After a well has been drilled under a well drilling permit, the quality of the water shall be tested in accordance with the following.
(A) Class I wells - water quality report.
(1) Groundwater samples shall be analyzed, at a minimum, for the parameters reported in Table 1. The township may require analysis for additional parameters, if information available to the township indicates the potential presence of additional contaminants. The analysis shall be performed by a laboratory licensed by the commonwealth. The quality of the water from the well shall be certified by a state-certified laboratory, stating that it meets or exceeds state drinking water quality requirements, as adopted by the DEP.
(2) The groundwater sample to be analyzed by the laboratory shall be collected no more than ten minutes prior to completion of the short-term pumping test, or the well shall be pumped for a minimum of four hours and then sampled.
(3) The township can require additional testing for any well located within 1,000 feet of the boundaries of a property that contains, or did contain, a business involving the use, production, processing, storage and/or disposal of chemicals and/or petrochemicals, or has or had underground storage tanks. This testing shall be conducted for compliance with the United States Environmental Protection Agency’s Maximum Contaminant Levels and Secondary Maximum Contamination Levels for Selected Constituents in Drinking Water, the current edition.
(4) The following information shall be submitted with the water quality report:
(a) The laboratory report outlining the results of the analysis;
(b) The name, license number and address of the laboratory;
(c) A copy of the report prepared by the well driller;
(d) Location of the well where the sample was collected;
(e) Name of the person collecting the sample;
(f) Time and date of sample collection;
(g) The pumping water level at the time of sampling;
(h) Elevation of the ground at the wellhead;
(i) Depth of the well;
(j) Drilling method;
(k) Type of casing and grouting used;
(l) Level and type of treatment required; and
(m) Type and quantity of storage provided (if applicable).
(5) If the drinking water standards reported in Table 1 are not met, the water supply may be treated to lower the concentration of the contaminant below the standard. The proposed treatment system shall be approved by the township before it is installed. After approval and installation of the system, a sample shall be collected as provided in division (A)(2) above and analyzed by the same laboratory that did the previous analysis to verify that the treated water meets drinking water standards. Additional treatment facilities shall be installed until these standards are shown to be met. Any well that does not meet these standards shall not be approved. The results of any and all analyses shall be submitted to the township.
(B) Class II and Class III wells - water resources impact study. All drilling and testing of a Class II or III well shall be performed in accordance with the requirements of the DRBC and the DEP. These wells shall be sampled following the procedures outlined in the township subdivision and land development ordinance, and the groundwater samples analyzed for the parameters contained therein.
