The static water level immediately prior to the testing for yield.
(12) 
A hydrograph of the depth to the water surface during aquifer testing and the recovery period at the test well(s) showing corresponding pump and discharge rate in gallons per minute and the time at which readings were taken.
(13) 
A statement of the raw (before treatment) water quality conditions and any treatment required to comply with the standards set forth in § 26-241 of this Part.
(14) 
Log of depth to water surface at existing and monitoring wells during test pumping period showing when time readings were taken.
(15) 
The location of the test well(s) shall be mapped.
(16) 
Recommended depth for the pump.
[Ord. 262, 9/17/2007]
1. 
Residential. In order to be certified for use for a single-family dwelling, a Class 1 well must have a production of not less than six gallons per minute as established by a four-hour test and certified by the well driller. To the extent any other Township ordinance is inconsistent with this provision it is hereby repealed.
2. 
Class 2 and 3 Wells. For community water supply wells to be certified for use, a report shall be submitted by a licensed professional geologist qualified in hydrogeology indicating the anticipated yield of the well(s) and storage requirements for the proposed use.
[Ord. 262, 9/17/2007]
1. 
The applicant for a Class 2 or 3 well shall be required to install observation well/wells as part of the testing of a well. The required number of observation wells is indicated in Table 26-V-1. The observation well(s) shall be constructed in accordance with the following criteria:
A. 
The well(s) shall be located close enough to the pumping well(s) so that sufficient drawdown is created in the observation well(s) during the aquifer test so that the capacity of the aquifer to store water can be calculated. The location of the observation well(s) shall require written approval of the Township Code Official, to be given upon the advice of the Township Engineer responsible for water and sewer matters.
B. 
An observation well shall be drilled to intersect the deepest water-bearing zone of the test well and/or the same depth as the test well.
C. 
The well(s) shall have a minimum diameter of six inches.
D. 
Casing material, as specified by the Township, shall be placed to a minimum depth of 40 feet. Additional casing shall be installed to prevent collapse if the weathered zone is deeper than 40 feet.
E. 
All observation wells shall be equipped with a locking cap. A weather resistant lock and two keys shall be provided to the Township Code Official.
F. 
The well(s) shall be drilled in an area on the site that allows easy access by Township personnel. The developer/owner shall agree to provide access to Township personnel. If necessary, a stabilized access road shall be provided at the Township's direction.
G. 
The Township shall be permitted to monitor the well(s) on a monthly basis, or more often if necessary, to obtain water level measurements and pump the well(s) to obtain a water sample for laboratory analysis.
H. 
The owner/developer shall be required to obtain a well drilling permit from Wrightstown Township prior to drilling an observation well(s).
I. 
The observation well(s) shall be equipped with a continuous record water level recorder during the aquifer test.
