Dungeness Area Fecal Coliform Project
Water Quality Improvement Project
Dungeness Area:
Fecal Coliform Bacteria
Introduction
The Dungeness River flows out of the Olympic Mountains into Dungeness
Bay. Located at the north end of the Olympic Peninsula, the area’s
natural beauty and quality of life have attracted many newcomers during
the last decade. Much of that growth happened in the lower river
valley, in the rural, unincorporated areas of Clallam County. (See
Study Area
Map)
Water quality issues
The population growth is impacting water quality. Numerous on-site septic systems, some
of which are failing or improperly maintained; a proliferation of hobby
farms where management practices may be less that optimal; and
accumulated waste from many pets are contributing to increasing fecal
coliform bacteria levels in local water bodies. Johnson, Bell, Cassalery,
Matriotti, and Bagley Creeks have been placed on the state’s
Water Quality Assessment (303[d])
List of impaired waters due to unacceptable levels of fecal
coliform. In 2000, Washington Department of Health closed some areas of
Dungeness Bay to shellfish harvest, also due to high levels of fecal
coliform bacteria. The closure area was expanded in 2001, and again in
2003.
Why this matters
Fecal coliform is a type of “bacteria” common in human and animal
waste. It can make people sick and cause the closure of shellfish
harvesting beds. Bacteria can get into our waters from untreated or
partially treated discharges from wastewater treatment plants, from
improperly functioning septic systems, and from livestock, pets and
wildlife.
People can help keep bacteria out of the water. Properly collect,
bag, and trash dog poop. Check your on-site sewage system to make sure
it is maintained and working properly.
Status of the project
In June 2002 Ecology submitted a water quality improvement report, also known
as a total maximum daily load (TMDL), to EPA for approval. The TMDL
included the results and recommendations of a technical study done on the water
in the watershed, and an implementation strategy that briefly outlined how the
recommendations would be addressed. EPA approved the TMDL in July 2002.
There is a strong local commitment to recovering and protecting water
quality in the Dungeness watershed, and a variety of activities are
ongoing or planned to deal with the water quality issues.
