Various types and sizes of whole house water filtration systems are available to address potential water quality issues experienced in Merrimack well water or town water. Not only is matching the right technology important, sizing the system to meet the water usage demands of your home is also very important. Additionally, a professionally plumbed system is also critical as well as maintenance of the system throughout the years to optimize the useful life and proper functioning of your new equipment.
While symptoms of water quality issues such as bad odors & taste, staining of laundry, bathroom fixtures, etc. are indicators of problems, the preferred starting point is to get a water test to identify the minerals or contaminants in the water and at what quantity they exist. This will lead to an effective system recommendation and route to providing your home with excellent water quality. While certain minerals & contaminants can be tested on-site (iron, hardness, pH, total dissolved solids), health threat items like radon in water, arsenic in water, nitrates and others should be properly sampled and brought to a certified laboratory for testing that requires specialized equipment.
A water softener is a type of whole house water filtration system that is designed for removing hard water minerals (magnesium & calcium) as well as dissolved iron and manganese from the water. For water with high levels of iron or manganese (“the stainers”), an “up-flow” water softener is recommended to prevent mineral build-up in the bottom of the water softener. Also, high efficiency water softeners that are more efficient with both water and salt usage are preferred. For more information about hard water, see link at Hard water.
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. If you are experiencing a rotten egg smell in water, you likely have a hydrogen sulfide problem. For more detailed information on common regional taste and odor issues, see the link at bad odors & taste.
WHOLE HOUSE WATER FILTRATION – Radon & Arsenic in private wells
Other contaminants found in New England well water include Radon and Arsenic. A water softener will not remove these health threat contaminants.
Radon in water is safely removed with an aeration system that agitates the incoming well water, releasing the gas from the water in a sealed chamber. This gas is then safely vented to the outside ambient air.
Arsenic in water can be removed at the point of entry into the home by installing tanks filled with arsenic specific resin that captures the arsenic before it can get into the home’s water supply. Point of use systems for drinking water can use reverse osmosis technology to effectively remove arsenic as well. Speak to a water treatment professional to decide which system is right for you.
