Lead and Copper Inventory

Everett Public Works will be conducting an inventory of drinking water pipes throughout the city to determine whether there is lead in any part of our water system. The City of Everett has no known lead lines but we are still planning to inspect a subset of service lines in the City to confirm this. Everett is required to complete this inventory by October 2024 to comply with the Environmental Protection Agency’s (EPA) requirements related to lead and copper in local water systems. 

  1. Background
  2. Lead in drinking water

In 1991, the EPA published a new rule to control lead and copper in drinking water systems across the country, called the Lead and Copper Rule (LCR). As part of a 2021 change to this rule, the City of Everett is required to inventory its water system and report its findings to the EPA by October 2024. 

Everett conducted its latest round of monitoring in 2021. The EPA action level for lead is a maximum of 15 parts per billion for 90% of the samples. The highest level found in the 108 homes tested was ten parts per billion. The 90th percentile result—the highest result obtained in 90 percent of the samples—was two parts per billion.

Everett’s source water contains virtually no lead, and Everett has eliminated lead lines and connections from its distribution system. These results indicate that the lead level at household taps is most likely due to the corrosion of household plumbing systems. More information about lead monitoring requirements can be found at the Environmental Protection Agency's website.
