The Limits of Water Quality Criteria

The Limits of Water Quality Criteria

A rising tide of acidity is overwhelming the global ocean. Estuaries and near-shore waters fall under the jurisdiction of states and the federal government, mandating treatment under the Clean Water Act, but criteria for action are uncertain and unclear.

Since the beginning of the industrial revolution, the global ocean has absorbed a third of the carbon dioxide emissions from fossil fuels, transforming it into carbonic acid. The acidity of the marine environment has increased by roughly a third since 1750, changing chemical processes vital to life, including shell and coral formation and the growth of bony structures in fish. This massive change in ocean chemistry is a growing water quality problem that focuses attention on the surprisingly difficult business of determining whether and how a particular water quality standard has been violated. Such attention brings with it a larger question of whether water quality criteria are legally sufficient under the CWA if they are difficult or impossible to test as a practical matter, and highlights the changing role of the act as it is used to combat a new class of water pollution.

Washington State Targets Pollutants that Lead to Ocean Acidification

Washington State Targets Pollutants that Lead to Ocean Acidification

BY: DAVID MALAKOFF, Science

In the first state-level action of its kind, the governor of Washington today announced that her state will try to protect valuable shellfish industries and marine life from ocean acidification. Responding to a report that she requested, Governor Chris Gregoire said she has directed state agencies to take steps to reduce the pollutants that contribute to acidification. She also plans to ask the state legislature to establish a new acidification research center at the University of Washington (UW), Seattle.

Oceans' rising acidity a threat to shellfish — and humans

Oceans' rising acidity a threat to shellfish — and humans

Peering into the microscope, Alan Barton thought the baby oysters looked normal, except for one thing: They were dead.

Slide after slide, the results were the same. The entire batch of 100 million larvae at the Whiskey Creek Shellfish Hatchery had perished.
