Liberty Lake Water Quality
Liberty Lake's Water District and Sewer System
During the 1960s, Liberty Lake, Washington faced significant environmental challenges, including a surge in blue-green algae caused by unsewered homes, leaking sewer pipes, and stormwater runoff.
In response, the Liberty Lake Water District (LLSWD) was formed in 1973. The district is dedicated to safeguarding the water quality of Lake Liberty, the aquifer, and the Spokane River. Doing so instills water conservation, backflow prevention, and health protection for the general public. It also maintains the watershed and provides Liberty Lake residents with reliable sewer and water utility services.
Water Quality Testing and Contaminant Analysis
The Liberty Lake Sewer and Water District (LLSWD) is committed to transparency and safety, providing annual Consumer Confidence Reports to keep you informed about the quality of your drinking water. According to their 2023 Annual Drinking Water Quality Report, we share the following information:
The highest levels of arsenic and nitrates found in pump stations within the LLSWD service area boundaries are below the legal limit.
Radioactive compounds found in LLSWD pump stations are also within legal limits.
The presence of lead and copper is also within legal limits.
However, the Environmental Working Group (EWG) states that the legal limits for contaminants need to be updated. Five contaminants have been detected to exceed their guidelines.
| Contaminants | Contaminant Level | MCL | EWG Standards |
|---|---|---|---|
| Arsenic | 1.85 ppb | 10 ppb | 0.004 ppb |
| Nitrate | 0.842 ppm | 10 ppm | 0.14 ppm |
| Nitrate and Nitrite | 0.827 ppm | 10 ppm | 0.14 ppm |
| Radium, combined (-226 & -228) | 0.32 pCi/L | 5 pCi/L | 0.05 pCi/L |
| Total trihalomethanes (TTHMs) | 1.21 ppb | 80 ppb | 0.15 ppb |
