1 New Section; Groundwater Protection Act; Contaminated Wells; Monitoring. Amend RSA 485-C by inserting after section 6-b the following new section:
485-C:6-c Contaminated Wells; Monitoring. Upon receiving information that a drinking water well that is not a source for a public water system exhibits the presence of a man-made contaminant, other than road salt, but the concentration does not exceed an existing ambient groundwater quality standard, the department shall determine if the contaminant is increasing in the well by primarily measuring the contaminants in the well and comparing such measurements to any previous measurements, and therefore, should be monitored and whether it is possible to identify the source of the contaminant. If a responsible party is identified as the source of the contaminant and the department determines monitoring is warranted, the department shall require the responsible party to monitor the contamination at a frequency sufficient to provide advance warning of any exceedance of the standard. If the department determines that monitoring trends or other available information reasonably suggest that the concentration of the contaminant in the well is likely to exceed the ambient groundwater quality standard prior to the next scheduled monitoring date, the responsible party shall provide treatment or an alternative supply of drinking water that meets all applicable standards and is approved by the department.
2 Effective Date. This act shall take effect upon its passage.
