STOCKTON (CBS13) – Well-known environment activist Erin Brockovich is voicing her concerns about the City of Stockton’s plan to add chloramines to its drinking water.

“Congratulations to the City of Stockton, California… you’re adding ammonia to your drinking water because you’re too lazy and cheap to remove dirt (organics) from your water supplies,” Brockovich posted on Facebook.
