Section 335-7-5-.15 - Ground Water Quality

The quality of water produced from wells and springs must be determined through analysis of samples representative of the sources.

(a) Physical Quality. Water produced from wells or springs to serve a community or NTNC system shall be free of rock or sand particles, silt, mud, or other foreign material. If compliance cannot be judged through visual observation, the following procedures shall be followed:

1. A turbidity test shall be performed according to methods approved by the Department and the results submitted to the Department.

2. A sample of the water shall be subjected to centrifuge or filtering tests. The test method shall be submitted by the project engineer to the Department which shall review and approve the method and apparatus prior to testing. If the design and apparatus are approved, the full capacity of the well upon start-up shall be tested for ten minutes. The maximum acceptable amount of material collected is one part per million.

(b) Bacteriological Quality. Every new, modified or reconditioned groundwater source shall be tested for bacteriological quality. A minimum of three chlorine free water samples collected at various periods during the capacity test shall be analyzed for both total and fecal coliform (or E. coli) bacteria by a laboratory certified by the Department. After the final pumping equipment has been installed and properly disinfected, at least two samples of chlorine free water shall be analyzed by a laboratory certified by the Department for total and fecal coliform bacteria (or E. coli). All results shall be submitted to the Department.

(c) Chemical Quality. After completion of the finished community or NTNC well, representative samples shall be analyzed for all primary and secondary contaminants, including inorganic, radiological and VOCs (regulated and unregulated). These analyses must be performed by a laboratory certified by the Department and a copy of the results shall be submitted to the Department prior to a request for a final inspection. Plans for providing treatment facilities should be provided at this time should any parameter not meet established standards.
