Algal Bloom May Affect Taste and Odor of Water
Posted Date: 7/16/2013 1:00 PM

The North Texas Municipal Water District (NTMWD) reports that an algal bloom is increasing in its reservoirs and may begin to affect the odor and taste of water in Richardson and the other cities it supplies with water.

An algal bloom occurs naturally when high temperatures and dry weather provide good conditions for the Nostoc and Anabaena species of blue green algae to reproduce, or “bloom.” The phenomenon typically occurs in the North Texas region in late July and August and does not pose any health risks.

NTMWD employees monitor algae levels in the water and take steps to minimize the changes in taste and odor.

Currently, NTMWD is preparing to implement ozonation, a new water treatment process that is expected to reduce or eliminate many of the odor and taste issues experienced during lake algal blooms. Full implementation is expected to be complete in early 2014.
