What to do
Don't be taken in if a water filter company contacts you unsolicitedly or runs advertising suggesting that your water is unsafe or otherwise not fit to drink. One way to find out what's in your water is to check your water utility's so-called consumer confidence report. The EPA requires utilities to provide a CCR to their customers every year. You also might find the CCR printed in your newspaper or posted on your local government website.
If you have well water, the only way to know if it's safe is to have it tested. Call the EPA's Safe Drinking Water Hotline (800-426-4791) for the names of state-certified testing labs or for information about your local health authority, which might offer low-cost or free test kits. Or visit the Environmental Protection Agency's laboratory certification program online. You might find that you don't need a water filter after all.
