"Study Finds Unsafe Mercury Levels in Fish From Delta Watershed"

"The first comprehensive study of rivers and streams in California has found that sport fish in the Sacramento-San Joaquin Delta watershed have higher concentrations of mercury and PCBs than anywhere else in the state."

"The survey adds to the history of high mercury levels in sport fish in the Sacramento region and dovetails with recent research that found consumption of sport fish from certain Delta region streams remains high, despite knowledge of the high mercury levels.

The sport fish survey, conducted by the State Water Resources Control Board, surveyed 16 species from 63 locations in 2011."
