WS 07: Zone 2 Pumping Test

Approval to conduct a pumping test to delineate the Zone II for an existing well

MassDEP Drinking Water Program

The Details

What you need

The approval is to conduct a pumping test in order to delineate the Zone II for an existing well. Zone II is that area of an aquifer which contributes water to a well under the most severe pumping conditions that can be realistically anticipated (180 days of pumping at safe yield with no recharge from precipitation). Pumping tests must be conducted in accordance with Guidelines and Policies for Public Water Systems.

The pumping test is conducted in order to evaluate the hydrogeologic characteristics of the aquifer. This is necessary to accurately delineate the Zone II. After the Zone II is delineated, the town or water supplier may wish to implement wellhead protection zoning and non-zoning controls to protect groundwater quality.

A public water supply system must apply if it has been approved to pump 100,000 gallons per day or greater, but has not yet delineated the existing well's Zone II, and is required to pursue a Water Management Act Permit.

Prior to applying, applicants should consider how the data collected during the pumping tests will assist with generating the Zone II boundary. Please consult MassDEP staff prior to the pumping test concerning the data necessary for the delineation.

Note: Approvals of this type may require MEPA review. Please carefully examine 301 CMR 11.00, the MEPA Regulations, to determine if your project exceeds the MEPA review thresholds, or for more information contact the MEPA Unit of the Executive Office of Environmental Affairs, 100 Cambridge Street, Boston MA 02114, 617-626-1020. MassDEP cannot begin technical review of the application until the MEPA process has been completed, unless otherwise agreed to in writing. Copies of MEPA filings (with reference to any applicable Transmittal numbers) should be sent to the appropriate program offices in Boston and the MEPA Coordinator in the appropriate Regional Office.

Note: These additional requirements are intended to serve as a guide to the applicant. It does not necessarily include all additional requirements.
