Water quality is defined by the ‘standards’ we use

Washington Department of Ecology is in the early stages of revising water quality standards for our state, beginning with a series of meetings to find out what people think. See my story in yesterday’s Kitsap Sun for an overview, and check Ecology’s news release for the meeting schedule and process for proposing changes.

It’s hard to tell how aggressive Ecology will be about changing these standards. Given state budget limitations, the agency may opt to do little, yet Ecology officials say they are willing to address problems that people see in the existing standards or in their implementation.

What we’re talking about here is changing the definition what makes good, clean, safe water. Changing the standards could bring increased attention to individual streams, lakes and bays and possibly even trigger a new approach for all streams.

Water quality standards are the driver for creating the state’s list of impaired water bodies (the 303d list). They are used to write discharge permits for industrial facilities, sewage-treatment plants and stormwater outfalls. And in cleanup plans for polluted waterways, they provide guidance for allocating pollution limits among point and nonpoint sources.

Priorities for changes that could be made are expected to be announced next spring after all the comments are compiled and reviewed, including suggestions from state and local officials, according to Susan Braley of Ecology’s Water Quality Program. Nationwide standards, which are under continual review by the Environmental Protection Agency, sometimes require the state to make changes.

Some of the ideas that have been kicking about, in no particular order:

  • New standards for total petroleum hydrocarbons
  • New standards for certain kinds of pesticides harmful to salmon
  • New standards for copper, which are known to affect salmon
  • New standards for toxic chemicals known to affect human health
  • A change in the bacterial standard from fecal coliform to e. coli
  • Allowance for alternative indicators for the presence of human waste
  • Further refinements of temperature standards, which were updated in 2006 to protect bull trout
  • New standards for pH as related to ocean acidification
  • New rates for fish-consumption by people, which could change numerical standards for a range of toxics

If anyone tells me about other ideas, I will add them to the list.

To read the standards themselves, go to the Washington Administrative Code, Chapter 173-201A.
