Ground Water
(OP)
Looking for an answer. We installed a new well about a year ago. the local state health office district engineer (DE) is suspicious it is GWUDI. He has no hard eveidence to support his claim. The well is greater than the minimum distance of 50' from any surface water body. It's design meets all state and county requirements. The seal is set @ 63' the minimum depth is 50'. the bore hole is 20' into ignious rock. We measured pH, conductivity and temp. of the well and the nearby pond. No correlation. The DE is requiring us to add turbidity monitoring to our proposed Fe/Mn treatment plant and test the well water for coliform monthly for a year. Also perform MPA test before and after a significant rain (1") for one year. He has imposed an MCL of .3NTU. What arguments can anyone suggest that would force him to modify his opinion.

For a water system <1000 service connections the MCL for turbidity is .5NTU.

Consider yourself lucky with the 50 feet requirement, another state requires the following:
The source must be within 500 feet of a surface water source (year round or intermittent/seasonal) and meet one of the following hydrogeologic setting criteria
as determined by the Source Water Assessment or other Department approved hydrogeologic study;
· 500 feet within a fractured bedrock or layered volcanic aquifer;
· 200 feet within a coarse sand, gravel and boulder aquifer;
· 100 feet within a sand and gravel aquifer;
· 75 feet within a sand aquifer
