WATER FILTRATION IN MAYNARD
As a resident of Maynard, MA, you likely have the town supplying water to your home with water but may have a private well, both of which may benefit from water filtration. As is the case with many wells and water supplies in Massachusetts, there are certain common contaminants that find their way into the water supply. Later in this write-up, specific contaminants that are commonly found in Maynard private wells and the public water supply are identified and effective remediation methods are covered. Excellent water quality is achievable with the proper approach.
According to the most recent available Annual Water Quality Report, Maynard’s drinking water comes from seven groundwater sources. Wells #1–4 are constructed in sand and gravel deposits that overlie bedrock. These wells are 40–70 feet deep and are located in the southern half of Maynard. The remaining three wells, #5 -7, are approximately 400 feet deep into bedrock and are located in the northern half of Maynard. White Pond, a surface water supply located in Hudson and Stow, is no longer in service; however it remains available as an emergency backup supply

RECENT NOTIFICATION REGARDING TRIHALOMETHANES
Trihalomethanes (THM) are a group of four chemicals that are formed along with other disinfection by products when chlorine or other disinfectants used to control microbial contaminants in drinking water react with naturally occurring organic and inorganic matter in water. For more detailed information on THM, see the link at Trihalomethanes. The use of chlorine to disinfect water for the purpose of drinking produces low levels of various disinfection by-products with the trihalomethanes and haloacetic acids being the most common. The trihalomethanes and haloacetic acids have demonstrated carcinogenic activity in laboratory animals. Studies have been published which reported associations between THMs and bladder and colon cancer, and adverse pregnancy outcomes including miscarriage, birth defects and low birth weight.
EFFECTIVE REMOVAL OF THMs WITH WATER FILTRATION
To effectively remove THMs from your drinking water supply, a properly installed carbon water filtration system will work. The typical system can be installed either at the point of entry into your home with a tank filled with carbon or a smaller system, dedicated only to drinking water can be installed under a kitchen sink or other areas to feed a separate faucet for drinking. For an even greater level of filtration, a reverse osmosis system can be installed to feed a separate faucet which has even greater filtration capabilities. For more information on carbon filtration, see the link at Carbon filtration. For more information on reverse osmosis, see the link at reverse osmosis
OTHER POTENTIAL COMMON CONTAMINANTS- typically seen in private wells
Some common issues encountered in Maynard, MA private wells are manganese and iron along with low pH and sometimes the health threats radon and arsenic making their way into the water. Even in the public water supply, you may notice symptoms of iron, manganese or low pH in the water. Hydrogen Sulfide is evidenced typically by a rotten egg smell in your water, however this may also be caused by high Manganese levels in the water as well. A water filtration specifically for this problem is effective in correcting this. For a chart of symptoms, causes and solutions, see the link at Common Regional Water Problems
If testing results for Radon exceed the current Massachusetts guideline of 10,000 pCi/L (Pico curries per liter) in water, the radon must be removed from the water and it is recommended testing the air for Radon as well. It should be noted that New Hampshire requires action if radon is only at 2,000 pCi/L. Maine and Rhode Island actionable levels are at 4,000 pCi/L. For more information on radon see the link at http://h2ocare.com/wp-content/uploads/2015/09/radon-removal-from-well-water-91015.pdf
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
If your home is supplied by town water, you may notice odor and taste associated with Chlorine as this is used for disinfection purposes by the town to control microorganisms including bacteria and others.
Water Filtration Systems
Water filtration systems can be installed for the removal of any of the contaminants discussed above and more. Water softeners are typically installed to remove dissolved iron or manganese in the water through a technology called Ion Exchange. Particulate iron or manganese (which you can see in the water) can be removed with a properly sized sediment filtration set up. See more information on manganese in water, see the article at the following link Manganese in Water Article in Water Technology For more information on Iron in Water, see the article link at Iron Article in Water Technology Magazine
Arsenic is removed with tanks containing a specific media that “grabs” the arsenic out of the water. Removing radon from water requires a system in which the water is agitated in a sealed chamber then vented to the outside, sending the radon gas to ambient air. Other technologies and systems are used to remove other contaminants. Any water filtration system designed should start with a water test before an informed recommendation can be made.
Carbon water filtration systems are effective at removing chlorine and the associated taste and odors that come with it, as well as reverse osmosis systems, which incorporate carbon into the design. These systems can either be installed at the point of entry in your home, typically in the basement, or at a point of use for drinking water only.
