Water Filtration Bolton


All new wells in Bolton must be approved by the Board of Health prior to any well drilling amd must be tested after drilling to the approval of the Board. In many cases, some type of water filtration system or water softening will be required to remove health threat contaminants such as Arsenic, Radon, Nitrates or others. Additionally, water filtration or water softener systems may be desired to deal with the aesthetically displeasing affects of certain other minerals or contaminants that may be present in the water such as hardness, iron, manganese and low pH.


Water Filtration Testing
Water testing should be conducted by an EPA or Massachusetts state certified laboratory and should minimally include analysis for the parameters listed below. If you are uncertain as to how to take a proper sample and get it to a lab, you should contact a lab or water treatment professional for assistance. A qualified water treatment professional can test for certain items on-site while others will require a lab. The closest lab to Bolton, MA for having this testing done is Nashoba Analytical in Ayer, MA. Website link. Typical items tested for, among others, are as follows:

Coliform bacteria, pH
Arsenic, Radon
Chloride, Sodium
Iron, Sulfate
Lead, Conductivity (TDS)
Manganese, Nitrogen-Nitrate


You are responsible for your own water testing if you have a private well. Testing should be done periodically. Speak to a water treatment professional or state certified lab for information on how often to have your well tested.

Well Water Filtration for Bolton,MA


The common issues encountered in Bolton private wells are manganese and iron along with low pH and sometimes 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 tighter action levels are required in other states such as New Hampshire requiring action if radon is 2,000 pCi/L (pico curries per liter); Maine and Rhode Island are at 4,000 pCi/L and the EPA is recommending 4,000 pCi/L as an action level. 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 Arsenic in water see the link at Mass.gov Arsenic Info.  Additionally, see our article in Water Technology Magazine for more detail at http://www.h2ocare.com, and click on the publications link.




Water softeners are typically installed to remove dissolved iron or manganese in the water through a technology called Ion Exchange. Other water filtration systems, such as Sediment filtration will remove particulate iron or manganese in the water. Carbon filtration will remove chlorine and a host of other contaminants from the water, eliminating the odor and taste associated with it. 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, but then vented outside the home to ambient air. Other technologies and systems may be required to remove other contaminants.

Any water filtration  or water softener system designed should start with a water test before an informed recommendation can be made.
