Algae Bloom Tweaks Taste of Local Tap Water

Water district officials in Marin are treating an algae bloom that has given tap water a funny taste.

officials were handling a bloom at , according to a story in the , and Marin Municipal Water District officials were dealing a similar problem at Nicasio Reservoir.

NMWD General Manager Chris De Gabriele told the IJ that the lack of late spring rain led to the lake water being more stagnant than usual but that the problem is dissipating.

MMWD Spokesperson Libby Pischel said some with more sensitive taste buds may have noticed their water “tastes off.”

“It doesn’t have that great taste that people expect from our water,” Pischel said.

An algae bloom often happens on a cyclical basis when a reservoir gets a lot of sun, Pischel said. Workers are treating the reservoir with copper sulfate, she said.
