Test your tap water
Ask a certified laboratory which tests it offers for lead, bacteria, and other contaminants relevant to your home; a $20-$50 kit may cover only certain contaminants.
Consider a certified water filter
NSF/ANSI-certified filters reduce the specific contaminants listed on their certification. Match the filter to your test results for best protection. Try our filter matcher
Contact your water utility
Request the latest Consumer Confidence Report (CCR) from your water provider. It reports monitored contaminants detected in the utility's water and related compliance information.
Check for lead in your home
65% of homes in this county were built before 1980. Older plumbing and solder can leach lead into drinking water, especially after water sits in the pipes.
