Lower White River pH water cleanup plan

Total Maximum Daily Load

June 16, 2022 - July 15, 2022, 11:59 p.m.

We invite you to comment on the draft Lower White River pH water cleanup plan.

Read the draft plan.

This waterbody and its tributaries are on Washington's polluted waters list for pH problems. Several years of monitoring data show pH in the White River regularly exceeds the upper end of the healthy pH range. If the pH in water is too high, it could be harmful for fish and other aquatic life. The plan describes what needs to happen to clean up the pollution so the river meets water quality standards.

The federal Clean Water Act requires states to develop a Total Maximum Daily Load (TMDL) — or water quality improvement project — plan for each water body on the state's polluted waters list, also known as the 303(d) list. This science-based approach assigns a numerical value that represents the highest amount of a pollutant a surface water body can receive and still meet the water quality standards. Learn more about the TMDL process.
