As beautiful as the well preserved rural town of Groton, MA is, if you have a private well supplying your home’s water needs, the quality of that water may require some type of water filtration system or water softener. A properly designed, installed and maintained water filtration system will provide you with truly excellent water quality for your home or business.
START WITH A WATER TEST
Water testing should be conducted by an EPA or Massachusetts state certified laboratory and should minimally include analysis for the parameters in the table below. If you are uncertain as to how to take a proper sample or what to test for, you should contact a lab or water treatment professional for assistance. 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:
PRIVATE WELLS AND WATER TESTING RESPONSIBILITY
You are responsible for your own water testing if you have a private well, not the town. Most towns’ Boards of Health will require certain testing prior to moving into, or selling a home. The proper on-going testing intervals can be determined by discussing your particular situation with a water treatment professional.
COMMON WATER QUALITY ISSUES IN GROTON
Common issues encountered in Groton private wells are manganese and iron along with low pH and sometimes the health threats radon and arsenic making their way into the water. 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 and the Board of Health recommends testing the air for Radon as well. It should be noted that New Hampshire requires action if radon is 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 (miligrams per liter) or 10 parts per billion. For more information on this see the link at http://www.mass.gov/eea/agencies/massdep/water/drinking/arsenic-in-private-well-water-faqs.html. Hydrogen sulfide is typically evidenced by a rotten egg smell in the water, however, this can also be a sign of high manganese. A properly specified water filtration system will correct this problem.
EFFECTIVE WATER FILTRATION SYSTEMS
A water filtration system can be installed for the removal of any of the contaminants listed in the above table and more. A water softener is typically installed to remove dissolved iron or manganese in the water through a technology called Ion Exchange. Sediment filtration will remove particulate iron or manganese in the water. Arsenic is removed with tanks containing a specific media that “grabs” the arsenic out of the water. Removing radon from water requires a system where the water is highly agitated releasing the radon gas from the water into a sealed chamber, then vented outside the home to ambient air. Other technologies and systems may be required to remove other contaminants. These systems are typically installed in the basement at the water supply point of entry.
Again, any water filtration system designed should start with a water test before an informed recommendation can be made.
