Algae Bloom Affecting Water Taste and Odor
Zone 7 Water Agency, which provides all drinking water to DSRSD, has reported that water-borne algae is currently affecting the taste and odor of the water delivered to its local treatment plants. The current algal bloom is temporary and should clear up naturally within a week or two. Zone 7's water treatment process ensures the water is safe to drink and meets all state and federal standards.
When water-borne algae are present in source water, Zone 7 adds powdered activated carbon to reduce the dirty, musty taste and odors, but this treatment is not 100 percent effective. To address this, Zone 7 is upgrading its plants by adding ozone treatment over the next few years. Ozone is significantly more effective than other treatment technologies at treating algal byproducts that cause the unpleasant taste and odor.
