Safety concerns about drinking water in Door and Kewaunee counties have renters and homeowners wondering what steps they can take to reduce or eliminate contaminants. While there are filters that can be attached to faucets, water treatment experts say your best bet is to go with a reverse osmosis system. An RO system eliminates molecular contaminants that are smaller than water molecules. Jeff Tebon with Culligan Water Conditioning Services of Sturgeon Bay says it's simple to find out what filtration system would work best for you.

Tebon says reverse osmosis filtration is tailored to remove nearly all metals like iron and lead and organic contaminants and parasites from home drinking water.
