Municipal water filter all drinking and cooking water with a Berkey. Looking for options to do whole house filter. NOTE: my parents got a notice from Perdue Chickens (home based in Salisbury, MD) that their well water may not be safe. After they water tested, they gave my parents and neighbors a full house water filtration system. So, think about it, my parents have lived there for over 60 years drinking that water. Perdue has been there just as long. Just because you have well water doesnt mean you are safe.
