WATER SOFTENER / WATER FILTRATION SYSTEMS
Without a water softener, calcium and magnesium (the hardness minerals) can have devastating affects on your home’s plumbing as well as your ability to clean, even though the EPA has no published limits on these. The EPA maximum allowable level for iron as a secondary contaminant is .3 parts per million and for manganese is .05 parts per million. Small amounts of these minerals can create very noticeable, even devastating affects on your home’s water quality.
A water softener will provide very noticeably cleaner water if you have hard water minerals, iron, or manganese in your water. These contaminants can be removed with a water softener and/or a properly specified sediment filter depending on whether the contaminant’s form is in solution or particulate. The primary hard water minerals found are magnesium and calcium (the hardness minerals), while iron and manganese (“the stainers”) can also be found in Plymouth water, mostly in private wells. If other impurities are confirmed in the water test, they can be removed with other types of water filtration systems. A water test and analysis will determine the best course of action.
Hard water interferes with many cleaning tasks, from doing the laundry to washing dishes to taking a shower. Washing your hair in hard water may leave it feeling sticky and dull. Dishes and glasses get spotted and a film may build up on shower doors, bathtubs, sinks and faucets. Clothes can look dingy and feel rough and scratchy. Hard water can also cause a residue to build-up in pipes that can lower water pressure.
Water softeners vary, including up-flow versus down-flow which can make a big difference, particularly if there are elevated levels of iron or manganese in the water. In some cases where the water chemistry is more complicated, a different type of water filtration system may make more sense to remove iron or manganese.
The following chart identifies hard water levels. Compare your test data:
THE AFFECTS OF HARD WATER, MANGANESE & IRON
Hard water scale (see photo below) can build-up inside water heaters insulating the temperature sensor inside the tank creating extra work to bring the temperature up to the set level. This reduces the life of your hot water heater and will most likely require early replacement. Some other affects of these contaminants include corrosion and scaling inside pipes and major staining throughout the home’s showers, bathtubs, and sinks. 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. For more on hard water, see https://water.usgs.gov/edu/hardness.html. For those using their well water for outside lawn irrigation, iron and manganese can cause major staining of outside walkways, house siding and anyplace the water touches.

WHAT WILL A WATER SOFTENER REMOVE?
A water softener is effective in removing dissolved forms of iron & manganese and hardness minerals. To remove particulate iron or manganese, water filtration utilizing a cartridge filter with proper micron rating will be effective. Depending on the specific situation, this could require a series of filters with different size micron ratings to handle heavier levels in the water. Selecting the appropriate micron rating and style of filter can be determined by a water treatment professional based on water test results and other symptoms. For more information on Iron and Manganese in water, see our published articles in Water Technology Magazine at the following link: http://h2ocare.com/publications/.
WHAT WILL A WATER SOFTENER NOT REMOVE?
A water softener will not remove the health threat contaminants Radon and Arsenic which may be found in water and will require different water filtration methods. Arsenic in water can be removed at the point of entry into the home with 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. Radon can be safely removed with an aeration system that agitates the incoming well water, collects the gas from the water in a sealed chamber, then safely vents it to the outside ambient air. Speak to a water treatment professional to decide which system is right for you.
