No inventory counts on file
North Washington Street WSD serves about 14,500 people in Adams County, CO, but EPA's EPA SDWIS service line inventory, 2026 Q3 data has no service line counts for it. That doesn't mean the system has no lead. Ask the utility for its inventory, or check your own pipe with the steps below.
The most recent lead sampling period in EPA data (starting 01-JAN-2002) did not exceed the 15 ppb action level. Results are a 90th percentile across sampled homes, so individual homes can still be higher.

Where the water comes from
North Washington Street WSD's main water source is purchased surface water. It buys treated water from Denver Water Board. The seller treats the water, including corrosion control that keeps lead from dissolving out of pipes, while North Washington Street WSD is responsible for its own service line inventory and replacement program. It sells water to 3 other water systems: Northside Village MHP, Chaparral Village MHP, Franklin Mobile Home Park.
