[HISTORY: Adopted by the Board of Health of the Town of Ashland 5-9-2023. Amendments noted where applicable.]
ATTACHMENTS
Attachment 1 - Exhibit A
The purpose of this Regulation is to protect the health, safety, and general welfare of the residents of Ashland, Massachusetts from groundwater emanating from the Nyanza Chemical Waste Dump Superfund Site. There are potential risks associated with exposure to ground water contaminants through direct ingestion, dermal contact, inhalation, irrigation of lawns and food crops, or watering of animals that are later to be consumed. This Regulation identifies a "Groundwater Use Restriction Sector" where controls are required to prevent human exposure from the use and consumption of, and public exposure to, potentially contaminated groundwater; and to prevent the further migration of groundwater or a change in groundwater hydrology (flow patterns) due to the extraction or pumping of groundwater.
The primary intent of this Regulation is to:
A. 
prevent the use and consumption of, and public exposure to, contaminated groundwater drawn from the Groundwater Use Restriction Sector;
B. 
prevent the further migration and/or changes in flow patterns of contaminated groundwater;
C. 
establish controls to help minimize public exposure to contamination; and,
D. 
protect the integrity of current, past, and/or future remedial efforts for the Nyanza Chemical Waste Dump Superfund Site.
To protect the public from exposure to potentially contaminated groundwater, the Ashland Board of Health adopts the following regulation to establish a Groundwater Use Restriction Sector and restrict the use of groundwater in that Sector, under the authority of Massachusetts General Laws Chapter 111, Sections 31 and 122A.
These regulations and the testing requirements, herein, reflect prudent means of minimizing, but not eliminating the potential risk from exposure to groundwater contamination. Persons withdrawing water for drinking or irrigation are encouraged to stay informed about newly identified contaminants that may be contained in the groundwater they use, and to exercise prudence in all aspects of water withdrawal.
A. 
MassDEP: MassDEP shall mean the Massachusetts Department of Environmental Protection.
B. 
Groundwater: All water found beneath the surface of the ground including all subsurface water stored in bedrock, and overburden aquifers and recharge areas within the Groundwater Use Restriction Sector. Groundwater does not include waters found in fire ponds or any other surface water bodies.
C. 
Groundwater Use Restriction Sector: All of the parcels of land within the boundary depicted on Exhibit A in the Town of Ashland, attached to this Regulation and incorporated by reference.
D. 
US EPA: US EPA shall mean the United States Environmental Protection Agency.
E. 
Well: Any reference to a well includes a Drinking Water Well, Irrigation/Supply Well, or Monitoring Well as defined herein.

Contaminant: any chemical, including but not limited to volatile organic compounds, pharmaceuticals, pesticides, radionuclides and metals, for which a regulatory limit for the maximum allowable contaminant level in drinking water has been established by the Environmental Protection Agency and/or the Massachusetts Department of Environmental Protection. Contaminant shall also include any compound for which a recommended health advisory has been promulgated by the Environmental Protection Agency and or the Massachusetts Department of Environmental Protection.
J. 
Irrigation - a network of valves, pipes, tubing, and emitters that applies water directly into the root zones.
There is hereby established within the Town of Ashland a Groundwater Use Restriction Sector, as depicted on Exhibit A ("Groundwater Use Restriction Sector") and all of which is serviced by the Town of Ashland public water supply. Due to the historical presence of DNAPL (Dense Non-Aqueous Phase Liquid) and a plume of contaminated groundwater emanating from the Nyanza Chemical Waste Dump Superfund Site, a Groundwater Use Restriction Sector has been identified where controls are required to prevent the use and consumption of, and public exposure to groundwater; and to prevent the further migration of groundwater or a change in groundwater hydrology (flow patterns) due to the extraction or pumping of groundwater.
The parcels of land contained within the Groundwater Use Restriction Sector are within the boundary depicted on Exhibit A and can be identified using maps on file with the Town of Ashland's Assessors Office or online at the Town of Ashland's website. The specific Map and Lot numbers for the parcels as of the date of adoption hereof are also identified on Exhibit A. The boundaries of this Sector are based on the facts and data available in consultation with the US EPA and MassDEP, and subject to future revision or amendment. This Regulation and the Groundwater Use Restriction Sector shall be reviewed every 5 (five) years under the jurisdiction of the Board of Health and track and incorporate any findings from EPA's Five-Year Reviews. Any revision or amendment to the Groundwater Use Restriction Sector shall be considered an amendment hereto and shall require a vote of the Board of Health.
Within the Groundwater Use Restriction Sector, the following restrictions shall apply, except as specifically provided in § 316-6 (Exceptions):
A. 
The extraction, consumption, or use of groundwater for any purpose by any person, corporation, or business, including without limitation, irrigation, industrial, commercial, geothermal, and residential use, is strictly prohibited.
