Final Technical Guidance—New Guidance

DEP ID: 394-2125-001. Title: Aquifer Testing Guidance for Public Water Systems. Description: Department regulations at 25 Pa. Code Chapter 109 (relating to safe drinking water) require an aquifer test for some proposed public water systems (PWS) that intend to utilize groundwater sources. An aquifer test and derivation of aquifer hydraulics are necessary for public health and compliance with the Pennsylvania Safe Drinking Water Act (35 P. S. §§ 721.1—721.17). This technical guidance document outlines recommended aquifer testing procedures for systems that require a permit and for all other PWS's that intend to pump more than 100,000 gallons per day. Information provided in this technical guidance is a stand-alone document and replaces the corresponding procedures in Part II of the Public Water Supply Manual (Department ID: 383-2125-108) pertaining to aquifer testing. This policy reflects and supplements the Department's regulations in 25 Pa. Code Chapter 109. This guidance was published as draft at 43 Pa.B. 5660 (September 21, 2013) for a 30-day public comment period. Comments were received from one commentator. Subsequent to publication, the Department completed minor edits to account for the public comments and to improve readability and accuracy of the document. Revisions to the draft technical guidance document resulting from the public comments are described in the accompanying comment-response document.
