As a resident of Lincoln, MA, you may have your home supplied by either the town’s public water supply or your own private well, which may benefit from a water filtration system or water softener. The following provides information on both situations with regard to potential water quality issues or concerns.
PUBLIC WATER SUPPLY
The Town of Lincoln is supplied by both surface water and groundwater wells. Flint’s Pond, also known as Sandy Pond, is the primary year-round supply. Tower Road Well is a supplemental source used during peak periods and when Flint’s pond is off-line for servicing. The town of Lincoln’s Annual Water Quality Report can be seen at the following link: Annual Water Quality Report.
Depending on the source location, the Lincoln Water Department adds a very low concentration of either potassium hydroxide or sodium hydroxide to the drinking water in order to increase the pH (reduce the acidity) of the water to reduce the natural corrosive properties. Chlorine is added as a disinfectant at the Flint’s Pond facility and fluoride is added at both the treatment plant and the Tower Road well to aid in dental health and hygiene. Zinc orthophosphate is also added at both sites for corrosion control and to reduce levels of iron and manganese.
If you have any concerns about these additives to the water supply, you may consider contacting the Lincoln Water Department directly at 16 Lincoln Road, Lincoln, MA 01773. The phone number is 781-259-2600.
Common Water Quality Issues in Lincoln Private Wells
The most common calls from Lincoln residents with private wells for a water filtration system are with regard to correcting low pH, which is corrosive to the home’s piping and other plumbing fixtures as well as Iron, Manganese, Hard Water and High Total Dissolved Solids (TDS). When water test results show low pH and/or high levels of these other minerals, a properly designed water filtration system or water softener can remedy the problems. See the “Water Filtration Systems” section below for more detail on this.
In addition to the above systems described, there are many other types of systems to remove bad tastes & odors, sediment and many other objectionable minerals and contaminants in the water. There are “point of entry” systems that will provide filtration for all of the water entering your home or facility. Also, there are “point of use” water filtration systems that will provide filtered water at a sink or other single point of use, typically by feeding the filtered water to a designated, separate faucet. Starting with a water test will help steer to the right approach for you. For more on bad odors & taste in your water, see the link at http://h2ocare.com/bad-odor-taste-water/.
Any water filtration system or water softener recommendation should start with a water test before an informed decision can be made. To determine what type of water testing to have performed and how to take a proper sample, call a water treatment professional or a state certified laboratory. In summary, controlling your home’s water quality is attainable through proper water testing and equipment specification with today’s available water filtration technologies at a reasonable price. Proper on-going maintenance is also critical to maintain a consistent level of great water quality.
WATER TESTING YOUR WELL
As a home buyer or seller, there are always questions that come up regarding testing the water when a home is serviced by a private well. If you are buying, have bought or are selling a home that is serviced by a private well, you will need to make sure it is tested.
Water testing should be conducted by an EPA or Massachusetts state certified laboratory and should include minimally, an analysis for the parameters in the table below. If you are uncertain as what to test or 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 Lincoln, MA for having this testing done is Nashoba Analytical in Ayer, MA. 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:
If the testing results for Radon exceed the current Massachusetts guideline of ten thousand (10,000) pCi/L in water, then the radon must be removed from the water and it is recommended that testing the air for Radon is performed 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. A water filtration system that will agitate and remove the radon gas by venting it outside will correct the radon in water issue. If the results for Arsenic come in at or above .01 parts per billion, then a water filtration system for removing the Arsenic must be installed. For information on Radon, Arsenic, Iron, Manganese, see the publications at Articles on Contaminants. Hydrogen Sulfide is typically evidenced 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.
Water Filtration Systems
Water filtration systems can be installed in Lincoln for the removal of any of the contaminants listed in the above table and more. Water softeners are 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. pH can be brought to neutral with a neutralization tank containing food grade sacrificial media for this purpose. 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 system designed should start with a water test before an informed recommendation can be made.
