"Water Supply Challenges" Part Five of Five: Well water in area has issues but tests confirm few dangerous contaminants
Hard water is enough of an issue for area homes that receive their drinking water from wells that even the Poolesville town manager has a water softener installed at his home.
Water tests conducted by National Testing Laboratories for The Sentinel Newspapers showed the level of hardness at one sample site in Poolesville reached 210 milligrams per liter, 21 times the minimum detection level and twice the guideline set by the Water Quality Association and used by National Testing Laboratories.
Water hardness is not enforced by the Environmental Protection Agency like lead or other dangerous contaminants.
So while the water in Poolesville is still safe to drink, National Testing Laboratories director of business development Marianne Metzger said homeowners with hard water may want to consider treating it in order to prolong the life of their washing machines and sinks.
“It’s absolutely safe to drink. It’s totally an aesthetic issue,” said Metzger. “Knowing that you have hard water, you know it’s going to be harder on your appliances… It’s a choice that people have to make.”
