[Added by Ord. No. 2001-32]
A. 
Purpose and applicability.
(1) 
It is the intent of the requirements of this section that an aquifer test and analysis as set forth in Subsection C(1) be provided as part of a preliminary plat application of a major subdivision which subdivision is to be served by on-site wells. It is the intent that an aquifer test and analysis as set forth in Subsection C(2) be conducted for major subdivision of five or fewer lots. It is the intent that an aquifer test and analysis as set forth in Subsection C(3) be conducted as part of a submission of a nonresidential use preliminary site plan when the development proposed by such site plan is to be served by one or more on-site wells with an average daily water demand of 600 gallons or more.
(2) 
The deepening or replacement of a well that has the primary purpose of providing drinking water to a residence is exempt from the requirements of this section. A nonresidential use preliminary site plan when the development proposed by such site plan is to be served by one well with an average daily water demand of less than 600 gallons shall also be exempt from the requirements of this section. However, the installation of a second well with the primary purpose of irrigation, filling of swimming pools, or any other purpose other than to serve as the sole source of drinking water for a residence or nonresidential site plan with an average daily water demand less than 600 gallons must satisfy the requirements of Subsection C, regardless of the second well's average daily water demand. A well installed for irrigation, filling of swimming pools, or any purpose other than providing the sole source of drinking water is considered to serve a nonresidential use.
B. 
Waiver. If an applicant can show that given the expected average daily demand and distance to other nearby wells, the subdivision will not induce drawdown in any existing or future wells adjacent to the subdivision boundaries or any existing or future wells within the subdivision, then the applicant can request a waiver from the Planning Board for all or some of the requirements of this section.
C. 
Aquifer test and analysis. The testing procedures for a major subdivision shall be based on a hydrogeologic analysis and a minimum of one aquifer test. The hydrogeologic analysis shall include the review of available information, including but not limited to published maps and reports depicting Lebanon Township and surrounding municipalities, stereo pairs of aerial photographs, New Jersey Geological Survey (NJGS) Special Report No. 24, and M2 Associates' report "Evaluation of Groundwater Resources of Lebanon Township, Hunterdon County, New Jersey." In addition, the hydrogeologic analysis will include the design and conductance of aquifer test(s). The data collection shall be designed and evaluated by a qualified hydrogeologist. A geological and hydrogeologic report containing appropriate maps, well logs, pump test data and monitoring well data and complying with the requirements of this section shall be prepared and submitted. Prior to conducting any aquifer test, a preliminary hydrogeologic evaluation and the design of the aquifer test(s) shall be submitted for review by the Township. The aquifer test shall consist of at least one pumping test conducted at a sufficient rate and duration to be able to determine aquifer characteristics such as transmissivity and storage coefficient. As part of the aquifer test, observation wells are to be monitored to determine and evaluate the cone of depression, confirm aquifer parameters, and predict the effect of long-term pumping on existing and future wells.
(1) 
Aquifer test and analysis for major subdivisions.
(a) 
Aquifer test.
[1] 
The rate and duration of the aquifer test will depend upon the size of the proposed subdivision and expected average and peak daily demands for all wells. The aquifer test shall be conducted at a location most representative of site geologic conditions. For residential subdivisions, biasing of testing toward areas of increased fracture density may result in the Township requiring additional testing in areas of lower fracture density to ensure that adequate yield is available throughout the proposed subdivision.
[2] 
If the proposed site is underlain by two or more geologic zones (Precambrian Metamorphic and Igneous Zone and the Cambrian-Ordovician Limestone/Dolomite Zone as defined in the "Evaluation of Groundwater Resources of Lebanon Township, Hunterdon County, New Jersey"), then an aquifer test will be required for each zone. The test requirements for each zone will depend on the number of lots and size of units per zone.
[3] 
In the event that the preliminary hydrogeologic evaluation indicates that a surface water and/or groundwater divide separates the subdivision, an aquifer test will be required for each side of the divide.
[4] 
The average daily and average yearly water demand for the subdivision must be determined according to the guidelines in N.J.A.C. 7:10-12.7. The peak day demand is twice the average daily demand.
[5] 
To ensure that the pumping test adequately stresses the aquifer, the length of the pumping test will be equal to the greater of the following: a) the volume of water removed from the aquifer is equal to the number of dwelling units multiplied by the peak day demand (e.g., 10 four-bedroom dwelling units times a peak day demand of 1,600 gallons per unit equals 16,000 gallons); or b) eight hours. At a minimum, the pumping rate for the test should be equivalent to 120% of the expected long-term rate (e.g., if the expected rate for a dwelling is five gallons per minute, then the minimum rate for the test is six gallons per minute).
[6] 
For nonresidential use, demand should be determined based on N.J.A.C. 7:10-12.6. If the demand exceeds 100,000 gallons per day, a New Jersey water allocation permit must be obtained from the New Jersey Department of Environmental Protection. For demands less than 100,000 gallons per day, the length of the pumping test will equal the greater of the following: a) the volume of water removed from the aquifer is equal to the peak demand; or b) eight hours. The peak demand should be assumed equal to twice the average daily demand. At a minimum, the pumping rate for the test should equal 120% of the expected long-term rate.
[7] 
For mixed developments containing both residential and nonresidential properties, the residential portion will be tested as described above for residential developments. Each proposed well for the commercial portions will be tested as described in Subsection C(3) for nonresidential use. In addition, wells installed for the residential portion should be used as observation wells for the nonresidential testing and wells installed for nonresidential use should be used as observation wells for the residential testing.
[8] 
The number of observation wells required per aquifer test will depend on the number of dwelling units and/or commercial units for the subdivision. New and existing monitoring wells may be located such that they can be used as future water-supply wells but they shall be located in such a manner that will yield the most accurate information concerning the aquifer. Observation wells should be located parallel and perpendicular to strike of the primary fractures intersected by the tested well.
[9] 
All wells must be located in accordance with the minimum distances required by N.J.A.C. 7:10-12.12. For nonresidential developments with an expected average daily demand less than 2,000 gallons per day, one observation well is required. This well should be within 500 feet of the pumping well. For all other nonresidential developments, two or more observation wells are required. At a minimum, one of these observation wells should be within 200 feet of the pumping well. A second observation well must be within 200 feet and 500 feet of the pumping well. These two wells should be located along strike of the major water-bearing fractures intersected by the pumping well. If additional observation wells are necessary, these wells should be located parallel to secondary and tertiary fracture sets.
[10] 
A fracture trace analysis showing the location and orientation of fractures beneath the site must be included with the pumping test plan. This same analysis with additional information regarding septic system locations must be included in the final report.
[11] 
Major subdivisions of five lots or less to be used for single-family dwelling purposes shall conduct a pumping test on each well as outlined in Subsection C(2). All the wells in a major subdivision of five lots or less shall be installed and used as observation wells as each individual well test is conducted. For major subdivisions of six or more lots to be used for single-family homes, the recommended number of observation wells shall be as shown in Table 1.

[12] 
The observation wells and test well must have a geologic log describing the depth and types of soils and rocks encountered and the depth and yields of all water-bearing fracture zones. Furthermore, the logs should include static water level measurements and total yield estimates for each well. The observation wells should be completed to a similar depth as the test well. At least one of the observation wells should be within 200 feet of the test well and at least one observation well must be located along the preferential fracture direction between 200 feet and 500 feet of the pumping well. Additional observation wells should be located to evaluate potential secondary fractures and impacts to adjacent properties.
[13] 
The design of the aquifer test shall be developed using the applicable guidance from "Guidelines for Preparing Hydrogeologic Reports for Water Allocation Permit Application with an appendix on Aquifer — Test Analysis Procedures" NJGS GSR 29, 1992. The aquifer test shall be conducted according to the following procedure:
[a] 
Owners of existing wells on lots located within 500 feet of the subdivision boundary shall be given an opportunity to have their wells monitored during the aquifer test. Such opportunity shall be given by the applicant by notice via certified mail and shall give the time and place of the well pumping test. Furthermore, the notice shall indicate that such existing well may be monitored if agreed to by the well owner, provided the well is readily accessible. Such notice shall indicate that the existing well owner must respond within seven days and the applicant's responsibility is to monitor up to three wells on properties within 500 feet of the subdivision boundaries. If the owner of the lot within 500 feet of the subdivision boundaries decides to participate by agreeing to have their existing well monitored, they shall notify the applicant by certified mail. Such response shall be provided within seven days of receipt of the certified notice from the applicant. If the applicant receives no response within the time provided, the response shall be deemed to be negative.
[b] 
If the owner of a lot within 500 feet of the subdivision boundaries is to have his existing well monitored, the applicant shall bear full responsibility for protection of the well against contamination and shall return the well to its premonitoring condition to the satisfaction of the lot owner.
[c] 
In the case when more than three property owners within 500 feet of the subdivision boundaries decide to participate and to have their existing wells monitored, only three nearest to the test well need be monitored. However, if any of the property owners requesting monitoring have wells completed to a depth less than 100 feet, these wells must also be monitored in addition to the three nearest wells.
[d] 
Prior to conducting an aquifer test, the applicant shall submit the design of such aquifer test including the location of wells to be monitored on adjacent lots and qualifications of the persons and firm who will be performing the test for review by the Township. The applicant shall submit an escrow fee of $500 along with the design of the aquifer test. The purpose of the escrow fee is to cover the cost of Township review of the proposed aquifer test. Such review may include submission of such design to a qualified hydrogeologist representing the Township for review and recommendations.
[e] 
The pumping test will be comprised of three phases. The first phase will involve the collection of background water levels prior to the start of the test. The second phase will involve the pumping of water from the well and the monitoring of water-level drawdown in the observation and pumping wells. The third phase will involve the recovery of water levels in the observation and pumping wells after the pump has been shut down. This third phase of the test should, at a minimum, be the same length as the pumping phase.
[f] 
If at all possible, the pumping test (all three phases) should not be conducted during precipitation events. If precipitation occurs during the test, the applicant should provide precipitation amounts and sufficient data to show that the precipitation did not recharge the aquifer during the test and adversely impact the testing results.
[g] 
The background phase includes allowing the test well and observation wells to stabilize for a minimum of three days before the test. At a minimum, water levels should be collected from the test well and observation wells 24 hours and one hour prior to the start of pumping. It is the applicant's responsibility to collect sufficient data to determine background conditions and to ensure that antecedent influences can be fully characterized. Barometer measurements and additional water-level measurements can be made by the applicant to evaluate the change in water levels resulting from barometric pressure changes and/or influences from off-site pumping.
[h] 
On the day of the pumping phase, water levels shall be collected from all wells. For those wells showing a change of more than 0.1 foot, a second round of measurements shall be collected before starting the test. Additional rounds of measurements may be necessary to determine that the well is in equilibrium. However, if the applicant has barometric pressure and water-level data to indicate that the change in static levels is due to changes in barometric pressure, the applicant can submit these data in lieu of delaying the pumping test.
[i] 
The pump and discharge pipe shall be equipped with an orifice/manometer apparatus and calibrated flow meter to instantaneously measure flow rate and determine total volume pumped from the well. The discharge shall be directed so that it leaves the site without infiltrating to the aquifer. Any and all permits required by the NJDEP for the discharge of water must be obtained prior to starting the test.
[j] 
When the pump is started the flow rate shall be adjusted immediately to a uniform pumping rate as required for a constant rate test and in accordance with the approved pumping test plan. The flow rate should not vary more than 10% throughout the test. If the flow rate fluctuates more than 10%, the test may be deemed invalid and the applicant required to repeat the notification and testing process. At a minimum, the flow rate for the test should be equal to 120% of the flow rate required to satisfy the average daily demand.
[k] 
Water-level measurements during the pumping phase of the test shall be collected in accordance with Table 2. This same schedule shall be followed for the recovery phase of testing upon shut down of the pump in the test well.

If the water levels in the observation wells and test well do not fully recover to static (prepumping) levels within a length of time since pumping stopped equal to the length of pumping, the test will be deemed to have failed unless adequate data can be provided to ensure that the aquifer is of sufficient extent to prevent the mining of groundwater.
[m] 
Groundwater samples should be collected during the pumping test from the pumping well. The samples should be collected in accordance with the NJDEP Field Procedures Manual. At a minimum, the samples should be analyzed by a NJDEP certified laboratory for hardness, iron, manganese, copper, lead, nitrate, ammonia, chloride, and coliform bacteria. In addition, field measurements of pH, conductivity, and total dissolved solids should be made with calibrated instruments. If site conditions indicate potential historic uses of pollutants such as heavy metals, pesticides, herbicides, volatile organic compounds, and/or semivolatile organic compounds, these analyses should be conducted. Based on past historical operations at the site or at nearby properties, the Planning Board, at its discretion, may require additional analyses of groundwater to assess potential future and current impacts. The results of the water sample analyses will be used to assess background water quality.
[n] 
The Township may elect to have a person of its choosing monitor the aquifer test at the expense of the developer.
(b) 
Adjacent properties. The observation wells shall be placed to determine whether the cone of depression from the pumping well will extend beyond the subdivision boundary in any direction. This shall be determined by actual measurements or from projecting the drawdown based on observation well data. If the wells are in use, they should be allowed to stabilize before the pumping test begins. A minimum of two water level measurements shall be collected from each well before the test. For any observation well which has been pumped within the 24 hours preceding the test, two depth to water measurements at least one hour apart shall be collected.
(c) 
Hydrogeologic report.
[1] 
A hydrogeologic report shall be provided with each major subdivision application. The report shall document the design and implementation of the aquifer test. The report shall include all water level data collected during the three phases of testing, the calculations of aquifer characteristics such as transmissivity and storage coefficient, calculations of the cone of influence, potential impacts to adjacent well owners, and the long-term sustained yield for the wells. The report shall also evaluate and draw conclusions from the aquifer test based on data collected and evaluation of available information concerning geologic conditions. The report shall include a detailed hydrogeologic description of the aquifers encountered beneath the site and adjacent properties. The report must include a detailed evaluation of the water supply demand for an average and peak day and this demand should be supported with information on anticipated population, expected dwelling unit density, and size of dwelling units. An inventory of all wells within 1,000 feet of the proposed subdivision boundaries should be appended. Figures depicting site geology, topography, water-level elevations, and plans shall be included.
[2] 
In addition, all water-quality sampling data including copies of the laboratory reports should be provided with the hydrogeologic report. Tables summarizing the analytical results should be included.
[3] 
The report should include a detailed evaluation of potential impacts from subsurface sewage disposal systems on groundwater quality. A site plan depicting well, septic leach field, and fracture trace locations at a minimum scale of one inch equals 200 feet should be included. For any and all locations where a fracture or set of fractures intersects one or more wells and/or septic leach fields, a detailed assessment of treatment technologies should be included. The treatment technologies should provide adequate assurances that any and all groundwater pumped from the wells will satisfy federal and New Jersey drinking water standards and will not be adversely impacted by the septic leach field discharges.
[4] 
The hydrogeologic report shall be prepared and signed by a qualified hydrogeologist using applicable sections of GSR 29 as a guide. A qualified hydrogeologist shall be an individual who has received a minimum of a bachelor's degree in geology at an accredited institution or has completed an equivalent of 30 semester hours of geological education while obtaining a bachelor's or master's degree in a related field of engineering or science at an accredited institution. Such a person must also demonstrate five years of professional work experience in the practice of applying geologic principals to interpretation of groundwater conditions. The individual should provide a resume or curriculum vitae to document education and experience requirements.
[5] 
The hydrogeologic report shall include the name and license number of the well driller and pump installer. The report should include the names of the persons and firm responsible for collecting the water-level measurements. In addition, the report should include copies of the completed NJDEP well records.
[6] 
The aquifer test and analysis shall be deemed to have failed if such test cannot demonstrate to the satisfaction of the Planning Board that sufficient groundwater supply exists to supply water via wells at a rate meeting at least the average daily demand for the proposed development. If the drawdown is measured or projected to be more than one foot at any existing adjacent property well or along the subdivision boundary, the applicant's hydrogeologist must evaluate the impact on adjacent properties based on the actual condition of wells in that zone.
[7] 
If a drawdown of five feet or more is noted in any existing adjacent property well, or is projected at any property boundary, then the proposed subdivision shall have failed the aquifer test. In the event of a failed aquifer test, because a drawdown of five feet or more is noted in any existing adjacent property well or is projected at any property boundary, either the applicant should decrease the number of lots to lessen demand or demonstrate to the satisfaction of the Planning Board that the impacts will not significantly reduce yields to existing and future wells.
(2) 
Aquifer test and analysis for individual lots in a major subdivision of five or fewer lots.
(a) 
Aquifer test. The procedure for testing wells for subdivisions of five or fewer lots shall consist of pumping each of the subdivision wells individually for two hours at a minimum of five gallons per minute (gpm). During the testing of a well, no other subdivision wells shall be operating. After pumping for two hours, the pump shall be shut down and the rate of recovery measured. For the well to pass the test, the pumping rate of five gpm must be maintained for the full two hours and a recovery rate of two gpm must be achieved over the first 30 minutes following shutoff of the pump.
[1] 
In order to provide the necessary data to evaluate the pump test results, the following conditions shall be met:
[a] 
The well shall remain undisturbed for three days following drilling to allow aquifer conditions to stabilize.
[b] 
Water level measurements shall be collected from the well and accessible adjacent wells (within 500 feet) before starting the pumping test.
[c] 
When the pump is turned on, the discharge rate shall be monitored and maintained at a minimum of five gpm. The flow rate must be measured with a calibrated flow meter or orifice/manometer apparatus.
[d] 
Water levels in the pumping well and adjacent observation wells shall be collected according to the schedule in Table 2.[1]
[1]
Editor's Note: Table 2, referred to herein, may be found in Subsection C(1)(a)[13][k].
[e] 
Near the conclusion of the pumping portion of the test, groundwater samples should be collected from the discharge in accordance with the NJDEP Field Procedures Manual. At a minimum, the samples should be analyzed by a NJDEP certified laboratory for hardness, iron, manganese, copper, lead, nitrate, ammonia, chloride, and coliform bacteria. In addition, field measurements of pH, conductivity, and total dissolved solids should be made with calibrated instruments. If site conditions indicate potential historic uses of pollutants such as heavy metals, pesticides, herbicides, volatile organic compounds, and/or semivolatile organic compounds, these analyses should be conducted. Based on past historical operations at the site or at nearby properties, the Planning Board, at its discretion, may require additional analyses of groundwater to assess potential future and current impacts. The results of the water sample analyses will be used to assess background water quality.
[f] 
Immediately after the pump is shut off, water-level recovery shall be measured accordance with Table 2.[2] The recovery rate shall be determined from these water-level recovery measurements for the first 30 minutes after the pump is shut down. The measurements should indicate a flow into the well of at least two gpm over this interval.
[2]
Editor's Note: Editor's Note: Table 2, referred to herein, may be found in Subsection C(1)(a)[13][k].
[g] 
In the event that the well shows little drawdown (less than two feet) during the two-hour pumping portion of the test, pumping may continue in lieu of the recovery rate portion of the test. The minimum requirement for pumping after two hours is that a minimum rate of two gpm be maintained for an additional hour with no increase in drawdown. The recovery of the water level shall still be monitored after the shutoff of the pump.
[h] 
A report summarizing the well construction and aquifer testing shall be submitted to the Planning Board. The report should include the water-level measurements and recovery rate calculations. The report must include a detailed evaluation of the water supply demand for an average and peak day, and this demand should be supported with information on anticipated population, expected dwelling unit density, and size of dwelling units.
[i] 
The report should include the well driller's and pump installer's name and license numbers. In addition, the names of the person and firm that measured the water-level drawdown and recovery data, and calculated the recovery rate shall be provided. The report should include a copy of the completed NJDEP well record for all wells within the subdivision.
[j] 
Based on the results of the testing and report, the Township may request additional analyses of the pumping test data to evaluate aquifer characteristics, the potential cone of influence, and potential impacts to other nearby groundwater users.
[i] 
If the test well fails any part of the above test either by failing to maintain a pumping rate of five gpm for two hours or failing to recover at a rate of two gpm after pumping stopped, the well shall be considered unacceptable and the applicant shall either replace the well or deepen the well to intercept additional fractures or add additional well storage. After well replacement or deepening, the entire test procedure shall be repeated on the new or deepened well. If the new or deepened well fails the testing procedure, the lot may, at the discretion of the Planning Board, be classified as unacceptable for development.
(b) 
Adjacent wells. Existing wells within 500 feet of the test well or on adjacent lots shall be identified as observation wells for the test. The applicant shall notify the owners of adjacent lots which contain wells within 500 feet of the test well and such owners shall be given an opportunity to have their wells monitored following the same procedures set forth in Subsection C(1)(a)[13][a] through [c] of this section. In the case where more than three existing wells are located within 500 feet of the well to be tested, only the three nearest accessible wells need to be monitored. However, if any of the property owners requesting monitoring have wells completed to a depth less than 100 feet, these wells must also be monitored in addition to the three nearest wells. If the wells are in use, they should, if possible, be allowed to stabilize before the pumping test begins. One water level measurement shall be collected from each well before the test. For any observation well which has been pumped within the 24 hours preceding the test, two depth to water measurements at least one hour apart shall be collected.
[1] 
If drawdown is measured or projected to be more than one foot at any existing adjacent property well or along the subdivision boundary, the applicant must notify the Township and evaluate the impact on adjacent properties based on the actual condition of wells, the static water level, and the depth of the pump in the existing well. The potential for adverse impacts needs to be evaluated by a hydrogeologist who will investigate the depth, yield, and pumping level of the effected well.
[2] 
If a drawdown of five feet or more is noted in any existing adjacent property well, or is projected at any property boundary, then the proposed subdivision shall have failed the aquifer test. In the event of a failed aquifer test because a drawdown of five feet or more is noted in any existing adjacent property well or is projected at any property boundary, either the applicant should decrease the water-supply demand or demonstrate to the satisfaction of the Planning Board that the impacts will not significantly reduce yields to existing and future wells.
(3) 
Aquifer test and analysis for nonresidential use subdivision and/or site plan.
(a) 
Aquifer test.
[1] 
An aquifer-pumping test shall be conducted when a nonresidential use is proposed and will be served by on-site groundwater supply. The pumping rate and total gallons pumped during the pumping test should demonstrate that the needed water is available without detrimental impact on the aquifer or nearby wells.
[2] 
Demand shall be based on N.J.A.C. 7:10-12.6. If the demand exceeds 100,000 gallons per day, a New Jersey water allocation permit must be obtained from the New Jersey Department of Environmental Protection. For demands less than 100,000 gallons per day, the length of the pumping test will equal the greater of the following: a) the volume of water removed from the aquifer is equal to the peak demand; or b) eight hours. The peak demand should be assumed to equal twice the average daily demand. The average daily demand shall be calculated from the projected maximum monthly usage. At a minimum, the pumping rate for the test should be equivalent to 120% of the expected long-term rate.
[3] 
For nonresidential developments with an expected average daily demand between 600 and 1,999 gallons per day, one observation well is required. This well should be within 200 feet of the pumping well. For developments with expected daily demands from 2,000 to 9,999 gallons per day, two observation wells are required. One of these observation wells must be within 200 feet of the pumping well. A second observation well must be within 200 and 500 feet of the pumping well. These two wells should be located along strike of the major water-bearing fractures intersected by the well. If a well(s) on one or more adjacent properties are located within the distance limits above, and these wells can be disconnected for a period of 24 hours prior to and during the entire pumping and recovery phase, these wells can be used for observation in lieu of installing new observation wells.
[4] 
For all other nonresidential developments, three or more observation wells are required. Two of these wells should be located along strike of the major water-bearing fractures intersected by the well. Additional observation wells should be located to evaluate potential secondary fractures and impacts to adjacent properties. The number of observation wells should be in accordance with Table 3.

[5] 
The observation wells and test well must have a geologic log describing the depth and types of soils and rocks encountered and the depth and approximate yields of water-bearing fracture zones. The observation wells should be completed to a similar depth as the test well.
[6] 
The design of the aquifer test shall be developed using the applicable guidance from "Guidelines for Preparing Hydrogeologic Reports for Water Allocation Permit Application with an Appendix on Aquifer — Test Analysis Procedures" NJGS GSR 29, 1992). The aquifer test shall be conducted according to the following procedure:
[a] 
Owners of existing wells on lots located within 500 feet of the nonresidential development's property boundary shall be given an opportunity to have their wells monitored during the aquifer test. Such opportunity shall be given by the applicant by notice via certified mail and shall give the time and place of the well pumping test. Furthermore, the notice shall indicate that such existing well may be monitored if agreed to by the well owner, provided the well is readily accessible. Such notice shall indicate that the existing well owner must respond within seven days and the applicant's responsibility is to monitor up to three wells on properties within 500 feet of the site boundaries. If the owner of the lot within 500 feet of the site boundaries decides to participate by agreeing to have their existing well monitored, they shall notify the applicant by certified mail. Such response shall be provided within seven days of receipt of the certified notice from the applicant. If the applicant receives no response within the time provided, the response shall be deemed to be negative.
[b] 
If the owner of a lot within 500 feet of the subdivision boundaries is to have his existing well monitored, the applicant shall bear full responsibility for protection of the well against contamination and shall return the well to its premonitoring condition to the satisfaction of the lot owner.
[c] 
In the case when more than three property owners within 500 feet of the nonresidential development's property boundaries decide to participate and to have their existing wells monitored, only three nearest to the test well need be monitored. However, if any of the property owners requesting monitoring have wells completed to a depth less than 100 feet, these wells must also be monitored in addition to the three nearest wells.
[d] 
Prior to conducting an aquifer test, the applicant shall submit the design of such aquifer test, including the location of wells to be monitored on adjacent lots and qualifications of the persons and firm who will be performing the test for review by the Township. In the case where the nonresidential development to be served by a single on-site well with an average daily water demand of 600 to 1,999 gallons is unable to secure approval to monitor wells on adjacent lots, the applicant may design their aquifer test using recognized techniques to estimate approximate values of aquifer characteristics in lieu of installing an observation well on the property. The applicant shall submit an escrow fee of $500 along with the design of the aquifer test. The purpose of the escrow fee is to cover the cost of Township review of the proposed aquifer test. Such review may include submission of such design to a qualified hydrogeologist representing the Township for review and recommendations.
[e] 
The pumping test will be comprised of three phases. The first phase will involve the collection of background water levels prior to the start of the test. The second phase will involve the pumping of water from the well and the monitoring of water-level drawdown in the observation and pumping wells. The third phase will involve the recovery of water levels in the observation and pumping wells after the pump has been shut down. This third phase of the test should, at a minimum, be the same length as the pumping phase.
[f] 
If at all possible, the pumping test (all three phases) should not be conducted during precipitation events. If precipitation occurs during the test, the applicant should provide precipitation amounts and sufficient data to show that the precipitation did not recharge the aquifer during the test and adversely impact the testing results.
[g] 
The background phase includes allowing the test well and observation wells to stabilize for a minimum of three days before the test. At a minimum, water levels should be collected from the test well and observation wells 24 hours and one hour prior to the start of pumping. It is the applicant's responsibility to collect sufficient data to determine background conditions and to ensure that antecedent influences can be fully characterized. Barometer measurements and additional water-level measurements can be made by the applicant to evaluate the change in water levels resulting from barometric pressure changes and/or influences from off-site pumping.
[h] 
On the day of the pumping phase, water levels shall be collected from all wells. For those wells showing a change of more than 0.1 foot, a second round of measurements shall be collected before starting the test. Additional rounds of measurements may be necessary to determine that the well is in equilibrium. However, if the applicant has barometric pressure and water-level data to indicate that the change in static levels is due to changes in barometric pressure, the applicant can submit these data in lieu of delaying the pumping test.
[i] 
The pump and discharge pipe shall be equipped with an orifice/manometer apparatus and calibrated flow meter to instantaneously measure flow rate and determine total volume pumped from the well. The discharge shall be directed so that it leaves the site without infiltrating to the aquifer. Any and all permits required by the NJDEP for the discharge of water must be obtained prior to starting the test.
[j] 
When the pump is started the flow rate shall be adjusted immediately to a uniform pumping rate as required for a constant rate test and in accordance with the approved pumping test plan. The flow rate should not vary more than 10% throughout the test. If the flow rate fluctuates more than 10%, the test may be deemed invalid and the applicant required to repeat the notification and testing process. At a minimum, the flow rate for the test should be equal to 120% of the flow rate required to satisfy the average daily demand.
[k] 
Water-level measurements during the pumping phase of the test shall be collected in accordance with Table 4. This same schedule shall be followed for the recovery phase of testing upon shut down of the pump in the test well.

If the water levels in the observation wells and test well do not fully recover to static (pre-pumping) levels within a length of time since pumping stopped equal to the length of pumping, the test will be deemed to have failed unless adequate data can be provided to ensure that the aquifer is of sufficient extent to prevent the mining of groundwater.
[m] 
Groundwater samples should be collected during the pumping test from the pumping well. The samples should be collected in accordance with the NJDEP Field Procedures Manual. At a minimum, the samples should be analyzed by a NJDEP certified laboratory for hardness, iron, manganese, copper, lead, nitrate, ammonia, chloride, and coliform bacteria. In addition, field measurements of pH, conductivity, and total dissolved solids should be made with calibrated instruments. If site conditions indicate potential historic uses of pollutants such as heavy metals, pesticides, herbicides, volatile organic compounds, and/or semivolatile organic compounds, these analyses should be conducted. Based on past historical operations at the site or at nearby properties, the Planning Board, at its discretion, may require additional analyses of groundwater to assess potential future and current impacts. The results of the water sample analyses will be used to assess background water quality.
[n] 
The Township may choose to have a person of its choosing monitor the aquifer test at the expense of the developer.
(b) 
Adjacent properties. The observation wells shall be placed to determine whether the cone of depression from the pumping well will extend beyond the subdivision boundary in any direction. This shall be determined by actual measurements or from projecting the drawdown based on observation well data. If the wells are in use, they should be allowed to stabilize before the pumping test begins. A minimum of two water level measurements shall be collected from each well before the test. For any observation well which has been pumped within the 24 hours preceding the test, two depth to water measurements at least one hour apart shall be collected.
(c) 
Hydrogeologic report.
[1] 
A hydrogeologic report shall be provided with each nonresidential use subdivision/site plan application. The report shall document the design and implementation of the aquifer test. The report shall include all water-level data collected during the three phases of testing, the calculations of aquifer characteristics such as transmissivity and storage coefficient, calculations of the cone of influence, potential impacts to adjacent well owners, and the long-term sustained yield for the wells. The report shall also evaluate and draw conclusions from the aquifer test based on data collected and evaluation of available information concerning geologic conditions. The report shall include a detailed hydrogeologic description of the aquifers encountered beneath the site and adjacent properties. The report must include a detailed evaluation of the water supply demand for an average and peak day and this demand should be supported with information on anticipated population, expected dwelling unit density, and size of dwelling units. An inventory of all wells within 1,000 feet of the proposed subdivision boundaries should be appended. Figures depicting site geology, topography, water-level elevations, and plans shall be included.
[2] 
In addition, all water-quality sampling data including copies of the laboratory reports should be provided with the hydrogeologic report. Tables summarizing the analytical results should be included.
[3] 
The report should include a detailed evaluation of potential impacts from subsurface sewage disposal systems on groundwater quality. A site plan depicting well, septic leach field, and fracture trace locations at a minimum scale of one inch equals 200 feet should be included. For any and all locations where a fracture or set of fractures intersects the on-site water supply well and/or septic leach field, a detailed assessment of treatment technologies should be included. The treatment technologies should provide adequate assurances that any and all groundwater pumped from the well will satisfy federal and New Jersey drinking water standards and will not be adversely impacted by the septic leach field discharges.

The hydrogeologic report shall be prepared and signed by a qualified hydrogeologist using applicable sections of GSR 29 as a guide. A qualified hydrogeologist shall be an individual who has received a minimum of a bachelor's degree in geology at an accredited institution or has completed an equivalent of 30 semester hours of geological education while obtaining a bachelor's or master's degree in a related field of engineering or science at an accredited institution. Such a person must also demonstrate five years of professional work experience in the practice of applying geologic principals to interpretation of groundwater conditions. The individual should provide a resume or curriculum vitae to document education and experience requirements.
[5] 
The hydrogeologic report shall include the name and license number of the well driller and pump installer. The report should include the names of the persons and firm responsible for collecting the water-level measurements. In addition, the report should include copies of the completed NJDEP well records.

The aquifer test and analysis shall be deemed to have failed if such test cannot demonstrate to the satisfaction of the Planning Board that sufficient groundwater supply exists to supply water via wells at a rate meeting at least the average daily demand for the proposed development. If the drawdown is measured or projected to be more than one foot at any existing adjacent property well or along the nonresidential subdivision/site plan boundary, the applicant's hydrogeologist must evaluate the impact on adjacent properties based on the actual condition of wells in that zone.
[7] 
If a drawdown of five feet or more is noted in any existing adjacent property well, or is projected at any property boundary, then the proposed subdivision shall have failed the aquifer test. In the event of a failed aquifer test, because a drawdown of five feet or more is noted in any existing adjacent property well or is projected at any property boundary, either the applicant should decrease the average daily demand or demonstrate to the satisfaction of the Planning Board that the impacts will not significantly reduce yields to existing and future wells.
