The primary hard water minerals are magnesium and calcium (the hardness minerals), while iron and manganese (“the stainers”) can also be found in Dunstable water, mostly in private wells. 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. Calcium and magnesium may have major affects on your home’s plumbing and your ability to clean, even though the EPA has no published limits on these.
The maximum allowable level (per the Environmental Protection Agency) 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 have very noticeable, even damaging affects on your home. A water test and analysis will determine the best course of action. A water softener will improve your water greatly if you have these impurities in your water.
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. Clothing 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 and significantly reduce the life of water using appliances.
OTHER AFFECTS OF IRON, MANGANESE & HARD WATER
Scale from hard water 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 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.

WHAT A WATER SOFTENER REMOVES
A water softener effectively removes dissolved forms of iron & manganese and hardness minerals from the water. To remove particulate iron or manganese, water filtration utilizing a cartridge filter with proper micron rating will be effective. Selecting an appropriate micron rating and style of filter can be determined by a water treatment professional based on water test results and other symptoms.
