If you are a resident of Carlisle, MA, your private well may require some type of water filtration, water softener or both. As is the case with many wells in Massachusetts, there are certain common contaminants that find their way into the water supply. This is not something to fret about as there are tried and true water filtration and water softener systems and methods to remove these contaminants and provide you with consistently safe and excellent water quality.
In fact, an advantage of having your own well water in Carlisle is that it gives you control over your water supply more than if you were supplied by a public water supplier (and you don’t have to pay for the water). Public water suppliers must add chemicals to the water to disinfect, or kill dangerous bacteria and other potentially harmful substances in the water. The net result of this is safe water, but may include aesthetically displeasing tastes and odors, etc. Chlorine is probably the most typical of these chemicals. Having your own private well usually entails some type of water filtration system or water softener, however this will result in a very high quality water result for your home.
WATER TEST FIRST!
Prior to considering any type of water filtration or water softener system, water testing should be conducted by an EPA or Massachusetts state certified laboratory and should include analysis for the parameters in the table 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. The closest lab to Carlisle for having this testing done is Nashoba Analytical in Ayer. http://www.nashobaanalytical.com/. They can walk you through the steps required to complete this task. They are a reputable state certified laboratory. Typical items tested for are as follows:
|Total Dissolved Solids||Copper|
In addition to the above requirements, for all property located in Residence District A (an area around the traffic circle in the middle of town near Ferns Country Store), the Board of Health requires testing for Volatile Organic Compounds including Methyl Tertiary Butyl Ether (MTBE). The Carlisle Board of Health can give you a more specific interpretation of what territory Residence District A encompasses. MTBE was used in the past as a fuel additive in gasoline to reduce airborne emissions and may have reached some well water in Carlisle from seepage into the ground from fuel tank leaks. This has happened all around the country, however testing and proper water filtration has proven effective. 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. Arsenic has a maximum contaminant level of .01 parts per million. These and other maximum contaminant levels will be identified on the completed water test analysis provided by the lab.
Water Filtration / Water Softener Systems
Water filtration and/or water softener systems can be installed for the removal of any of the contaminants listed in the above table from your well water. Water softeners are typically installed to remove dissolved iron or manganese in the water through a technology called Ion Exchange. Particulate Iron or Manganese is removed with sediment filtration properly sized. 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 safely out of the home to ambient air. Hydrogen Sulfide is evidenced typically by a rotten egg smell in 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. Other technologies and filtration systems are used to remove the other contaminants. Any water filtration or water softener system designed should start with a water test before an informed recommendation can be made.
In summary, your well water in Carlisle, with a properly designed water filtration system or water softener will provide safe, clean water.
