Every day, us Yakimans use our city’s water for for drinking, cooking, or irrigation. But have you ever stopped to wonder what’s actually in your tap water?
At Independent Water Service of Yakima, we believe that understanding your water quality is the first step toward protecting your health and your home. Let’s take a closer look at the reality of Yakima’s water and why it matters. Keep in mind that we’re generally referring to municipal water. Well water is a different beast and has different risks that you need to be aware of.
Where Yakima’s Water Comes From
Yakima’s water supply primarily comes from the Naches River, supplemented by groundwater wells operated by the City of Yakima Water/Irrigation Division. According to the City of Yakima 2023 Water Quality Report, the city’s water system serves over 90,000 residents and consistently meets, and often exceeds, federal drinking water standards set by the Environmental Protection Agency (EPA).
However, even water that meets federal guidelines can contain trace levels of contaminants that you should be aware of.
Common Contaminants Found in Yakima Tap Water
Water testing in Yakima has occasionally found small amounts of the following:
- Disinfection Byproducts (DBPs): Formed when chlorine used to disinfect water reacts with organic matter. High levels over time may pose health risks.
- Nitrates: Particularly a concern in rural areas where agricultural runoff can seep into groundwater.
- Hard Water Minerals: Yakima water is moderately hard, containing calcium and magnesium, which can cause scale buildup in pipes and appliances.
- Lead and Copper: While not typically an issue in the source water, older plumbing can leach lead or copper into tap water, especially if the home was built before 1986.
It’s important to note that the City of Yakima routinely tests for these contaminants and remains within the EPA’s safety limits. However, individual homes may still experience higher levels depending on plumbing, household water usage, and location.
Seasonal Changes and Water Quality
In Yakima, spring snowmelt and summer irrigation demand can impact water sources. During these periods, runoff can increase the presence of sediment and agricultural chemicals in water supplies. The city adjusts treatment processes during these times, but homeowners using private wells are especially advised to conduct regular water tests in the spring and late summer.
Why You Should Still Test Your Water
Even if municipal water meets EPA standards, your individual water quality can vary. Factors like aging pipes, plumbing materials, and household filters all affect the water you drink. Testing your home’s water once a year, or installing a certified water filtration system, can offer extra protection and peace of mind.
