Lead in Water Systems

Omak's drinking water sources don't contain lead. However, lead can leach into water from plumbing materials, such as lead-based solder and brass fixtures.

Reduce Your Lead Exposure

There are a few simple steps you can take in the home to reduce the risk of lead in your drinking water:

If water has been standing in pipes for over 6 hours, flush out the pipes by running the tap for 2 minutes. To save water, use the water you flush out for watering plants or doing dishes.

Always draw drinking and cooking water from cold water tap — lead dissolves more quickly in hot water.

Never make baby formula or other drinks or food for children from the hot water tap. Start with water taken from the cold water faucet (after flushing) and warm it if necessary.

If you are making plumbing changes, be sure to select low-lead or no-lead fixtures. As of January 2014, a new federal law is in effect, reducing the amount of lead in plumbing fixtures from 8 percent to 0.25 percent. Manufacturers are already offering faucets that meet the new standard.

Test your home drinking water

To have your home water tested for lead, contact a certified lab near your area. The Washington State Department of Ecology is responsible for certifying labs in Washington and maintains a database where you can find labs certified to test drinking water. Analysis costs range from $25 to $50. Please contact the laboratories directly for sample collection procedures and prices.

Lead and Copper Rule Compliance

The City of Omak began sampling and analysis to meet the EPA Lead and Copper Rule in 1992. The Lead and Copper Rule sets action levels of 15 ug/L (0.015 mg/L) for lead and 1300 ug/L (1.3 mg/L) for copper. A utility must make treatment changes or meet other requirements if the action level for either lead or copper is exceeded in more than 10% of the residential samples.

We have put a tremendous amount of effort into reducing lead and copper levels from home plumbing materials. 

These improvements have resulted in substantially lower lead levels in home tap samples. Omak now qualifies for reduced monitoring for lead and copper (20 homes once every 3 years). Omak has met all requirements of the lead and copper rule since 2003.

Lead Line Inventory

The City of Omak has over 2000 service lines to homes and businesses in the City. Through records we have an accurate inventory and can determine we do not have lead service lines to any of the homes or businesses we serve. If you have any questions about your service line please contact our Public Works Department and we can help you determine the materials used in your line. Contact Omak City Hall at (509) 826-1170.
