Ensuring that California coastal waters are safe for people and marine life has consistently been a priority for the state and for USC Sea Grant. Over the decades, the nature of USC Sea Grant’s research investment in coastal water quality has shifted from a focus on sewage and associated bacteria to a focus on stormwater runoff and viruses. The focus will continue to shift as climate change has become a major driver of emerging issues of drought, water conservation, and low-impact development and as legacy pollutants and chemicals of emerging concern increasingly affect coastal waters in our region.
