The US Environmental Protection Agency (EPA) recently released its Lead and Copper Rule Revisions (LCRR)which includes the Lead Service Line (LSL) Inventory requirement.  This initiative requires public water systems, including the City of Snohomish, to inventory all water service lines and the materials they are made of, all the way from the water main to the meter (public side) and meter to the building (private side).  The mandate aims to help safeguard public health by ensuring that water systems across the United States develop and maintain comprehensive inventories of service line materials. The City has completed the required LSL Inventory. We are pleased to announce no lead service lines have been identified within the City's water system.

Our efforts have resulted in the identification of both city-owned lines (from the water main to the meter) and private lines (from the meter to the structure). Even though no lead, unknown, or galvanized requiring replacement (GRR) service lines have been identified, we cannot definitively confirm no presence of lead in your service line or internal plumbing, although it is unlikely based on the information available and field investigation.

This inventory is critical to ensuring the safety and highest quality drinking water for our residents, businesses, and visitors.

Is there lead in our drinking water?

Hundreds of water samples are collected annually at the water source, during treatment and in the distribution system in order to determine the presence of any radioactive, biological, inorganic, volatile organic or synthetic organic contaminants. 

Lead in drinking water is primarily from materials and components associated with service lines and interior plumbing. Lead and copper can leach into a water system from the piping or the fixtures (faucets). Homes built or plumbed with copper pipe before the 1985 lead solder ban, may have used lead-based solder. 

The City is required to monitor for the presence of lead and copper at household taps every three years. Snohomish in conjunction with the City of Everett participate in a regional monitoring program. Ongoing testing shows that the City of Snohomish’s drinking water meets or exceeds all state and federal drinking water standards for lead and copper. For additional information on where our water comes from and testing results see the link below. 

What can you do?

Provide verification of your service line material - click here for information on how to do that.

We need your help to identify the material for the remaining water service lines from the meter to the building (private side). 

If you know your water service line material please request and complete a Pipe Identification Form and submit to:

You can drop the form off in person at City Hall (116 Union Avenue) either in the lobby or utility payment drop box in the north driveway. 

 The City of Snohomish is responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. 

Elevated levels of lead can cause serious health problems, especially for pregnant women and young children. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in water, testing methods, and steps you can take to minimize exposure is available from the Environmental Protection Agency website. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking.
