Section 7:10-9.3 - Determination of ground water sources to be evaluated for direct influence of surface water

(a) Except as provided at (b) below, each supplier of water shall monitor each raw water source for pH, turbidity, temperature, conductivity, coliform bacteria and/or particulate matter, in accordance with N.J.A.C. 7:10-9.5, if the source meets any of the following criteria:

1. The source is an infiltration gallery, spring, cistern, radial well collector or dug well;

2. The raw water quality data for the source indicates the existence of one or more of the following in the raw water: fecal coliform bacteria, Giardia cysts, or other pathogenic organisms associated with surface water;

3. The source is a well which has less than 50 feet of casing;

4. The source is a well and the annular space between the oversized borehole and the well casing is not grouted;

5. The source is located less than 200 feet horizontally from any surface water body that holds or carries water continuously for at least 60 calendar days in any year, including, but not limited to, a stream, river, brook, lake, reservoir, impoundment, pond or creek; and/or

6. The source is less than 200 feet horizontally from a source of microbial contamination which may involve a ground water discharge, including but not limited to, a septic system, cesspool, feedlot, stormwater detention basin or point discharge of highway drainage.

(b) The monitoring required pursuant to paragraph (a) above shall not apply to the sources described at (a)5 and 6 above if the supplier of water demonstrates that such source draws water from a low risk formation as defined in N.J.A.C. 7:10-1.3.

(c) By June 30, 1997, each public community water system shall submit for each source that meets the criteria in (a) above a completed Checklist for Determination of Ground Water Status to the Bureau of Safe Drinking Water in the Department. Public noncommunity water systems shall submit the checklist upon the request of the Department, where, based upon a history of noncompliance with applicable coliform standards, use of disinfectant treatment, and other physical evidence revealed by inspection, the Department determines that the system's ground water source may be at risk of contamination by surface water.

1. The Checklist shall specify the identification, location, construction, and microbiological quality of each source.

2. Any Checklist properly completed and submitted to and received by the Department prior to November 18, 1996 will be considered as complying with this subsection.
