The Kennewick Irrigation District is asking residents to clean filters and irrigation systems on a regular basis.
The district is experiencing issues with rapidly growing algae blooms.
The only way the algae can be destroyed is with herbicides and chemicals at levels dangerous to the environment.
In order to stop the blooms without using dangerous chemicals, people must keep their filters clean so water can continue to move through the canal. For more information, call 586-9111.
