If you are reading this and you are a resident of Hampstead, NH, you likely have a private well supplying your home with water which may require a water filtration system, water softener or a combination of filtration technologies. As is the case with many wells in New England, there are certain common contaminants that find their way into the water supply. Hampstead tends to have very high levels of iron & manganese in the water along with low pH. There are tried and true water filtration systems and water softener designs to remove these contaminants to provide you with excellent water quality.
Having your own well does give 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), however, having your own well shifts all responsibility for the safety and quality of your water to you.
COMMON HAMPSTEAD WATER QUALITY ISSUES
Very high levels of iron and manganese along with low pH tend to characterize the water in most Hampstead, NH wells. Due to these high levels, methods and technologies that may typically work on lower levels of iron and manganese may not be effective on these high levels. The highest level we have tested for and treated was at Phan Zone with iron at over 200 parts per million. To put this in perspective, the maximum EPA secondary contaminant level is at .3 parts per million! The system installed was unique but did the job and continues to work well. See the Water Technology Magazine article titled, “Iron So High It Was Almost Frightening!” at the following link: Iron Article in Water Technology Magazine. 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.
Water testing should be conducted by an EPA or 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 water treatment professional or lab for assistance. They can walk you through the steps required to complete this task. Typical items tested for include the following; however, you should discuss this with your water treatment professional of lab selected.
If the testing results for Radon exceed the current New Hampshire guideline of 2,000 pCi/L in water, the radon must be removed from the water and most Boards of Health recommend testing the air for Radon as well. . 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.
WATER FILTRATION SYSTEMS
Water filtration or water softener systems can be installed for the removal of any of the contaminants listed in the previous table and more. Water softeners are typically installed to remove hard water minerals, iron and manganese in the water through a technology called Ion Exchange. For very high levels of iron or manganese, the design of the equipment installation is of particular importance.
Arsenic is removed with tanks containing a specific media that “grabs” the arsenic out of the water. For more information on Arsenic in water, see the link at EPA Arsenic in water article.
Removing radon from water requires a system where the water is agitated to release the radon gas into a sealed chamber, then venting the radon gas safely outside the home to ambient air. Other technologies and systems are used to remove the other contaminants. Any water filtration system designed should start with a water test before an informed recommendation can be made.
