Water softener or water filtration system options can be very effective in improving water quality in Dedham, MA. If you have a private well, it is highly recommended that you get your water tested and analyzed. This is the only way to identify whether or not you should be considering a water filtration system or a water softener. Information on the public water supply is available in the town’s annual report. See the link identified in a later section of this write-up.
WATER SOFTENER SYSTEMS
Water softeners are typically installed to remove dissolved hard water minerals (calcium and magnesium) and dissolved iron or manganese in the water through a technology called Ion Exchange. To remove particulate iron or manganese, a properly sized sediment filter is required. According to information taken from the Annual Water Quality Report, average water hardness was identified at 116.5 mg/L (miligrams per liter) with a range from 89.9 to 143 mg/L.Hard water may result in scaling on plumbing fixtures and inside pipes, dull laundry, streaky glasses & dishware and will make it “harder to clean” than with soft water. When water falls as rain, it’s “soft” and free of hard water minerals. It picks up minerals as it passes through rock, sand and soil. Hard water is high in mineral salts, especially calcium and magnesium ions. This is no fault of the town, but just the cards they have been dealt. For more information on hard water, see the link at the Water Quality Association website at Perceptible-Issues/Scale-Deposits.
According to the Dedham Annual Water Quality Report, the average hardness level tested is in the high end of the moderately hard range (see scale below), while the upper level of the range tested is considered hard. See the hard water scale below:
DEDHAM’S PUBLIC WATER SOURCE
The District’s water supply is from groundwater. There are fourteen wells, six in Westwood and eight in Dedham. There are also emergency connections with the Massachusetts Water Resources Authority, the City of Boston and the Towns of Norwood and Needham. There is also the ability to purchase water from the MWRA on a routine basis, up to 36 million gallons annually, however less than 1% of the annual water requirement is accessed this way.
The District has two water treatment plants where water from all of its regularly pumped wells is filtered. Chlorine is added for disinfection, fluoride is added for preventing tooth decay, and iron and manganese (naturally occurring minerals found in New England groundwater) are removed. The pH and alkalinity are adjusted to neutralize the slightly acidic characteristics of the groundwater so that it is less corrosive to piping and plumbing. Numerous tests are performed for monitoring pH and other treatment plant performance indicators, while other parameters are analyzed daily, weekly, quarterly or annually depending on regulatory requirements.

BAD ODORS & TASTE IN WATER
For more on the removal of other bad odors and tastes in water, such as fishy, metallic, musty, etc., see the link at http://h2ocare.com/bad-odor-taste-water/. Chlorine can be removed with a carbon filtration system while removing other bad tastes and odor.
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.
