Key Differences

What Should I Do?

If either utility shows open violations or elevated PFAS records, consider:

  • Installing a reverse osmosis filter — removes PFAS, lead, arsenic, nitrates, and most heavy metals.
  • Requesting your utility’s annual Consumer Confidence Report (CCR) for the most current test results.
  • Ordering a certified lab water test if you want contaminant-specific data for your address.
