Water testing in Groton, MA

Water Testing

Testing should be conducted by an EPA or Massachusetts state certified laboratory.  Additionally, for proper sampling for what to test, you should contact a lab or water treatment professional for assistance. Furthermore, certain items can be tested for on-site by a qualified water treatment professional  For health threat contaminants, a proper sample should be taken to a certified state laboratory. Typical items tested for are as follows:


Coliform bacteria pH
Arsenic Radon
Chloride Sodium
Iron Sulfate
Lead Conductivity
Manganese Nitrogen-Nitrate

Common issues encountered in Groton private wells are manganese and iron along with low pH and sometimes radon and arsenic.  If the testing results for Radon exceed the current Massachusetts guideline of 10,000 pCi/L in water, the radon must be removed from the water.. Note that New Hampshire requires action if radon is only 2,000 pCi/L (Pico curries per liter), Maine and Rhode Island are at 4,000 pCi/L. The maximum allowable level of Arsenic in drinking water per the EPA is .01 mg/L (Milligrams per liter) or 10 parts per billion. For more information on this see the link at arsenic-in-private-well-water.
