Frequently asked
Is there lead in Warwick tap water?
WARWICK-CITY OF's most recent lead 90th-percentile result (2025) was 1.94 µg/L, below the 15 µg/L action level. It comes from sampled homes; your own pipes decide what reaches your tap.
Does Warwick have lead service lines?
In EPA's service line inventory (2026Q2), WARWICK-CITY OF reported 55 lead service lines, 3 galvanized lines requiring replacement and 0 of unknown material, out of 26,337 lines in total.
How do I know if my home has a lead service line?
Ask WARWICK-CITY OF whether your address appears in its service line inventory, which utilities must publish. You can also look where the water pipe enters your home: lead pipe is dull grey, soft, and shows shiny metal when scratched gently.
How do I reduce lead in my water?
Run the cold tap for a few minutes after water has sat for hours, use only cold water for drinking and cooking, and use a filter certified to NSF/ANSI 53 for lead reduction. Replacing a lead service line removes the main source.
