“Concentration”
is
the amount of a substance in a given amount of water (for
instance, bacteria colonies per milliliter). “Load”
refers to the total amount of a pollutant being carried by a
waterbody. It
is calculated by multiplying the concentration of the
pollutant times the volume of water. It’s
possible for a waterbody like the Dungeness River, which has
a large volume, to have a low concentration
and still be carrying a large load.
Also, a relatively small reduction in load can remove a lot
of bacteria from the system. |
Sampling
sites were chosen so the study could identify which stream reaches are
in most urgent need of cleanup activities.
In several areas, landowners are already working with the
County and Conservation District to improve practices on their land.
Here
are some of the study findings and recommendations:
Ø
Bacteria
concentrations must be reduced in several tributaries to the Dungeness
River to meet public health-based standards for clean water.
Ø
The
bacteria load in the Dungeness River and other freshwater sources
needs to be reduced to restore and protect shellfish harvest in
Dungeness Bay.
Ø
Matriotti
Creek is the primary contributor of bacteria to the Dungeness River.
During the wet season it contributes 46 per cent of the
Dungeness’ load; during the irrigation season 53 per cent.
Ø
During
the wet season, the area where the most fecal coliform bacteria enters
the River is between 0.1 and 0.3 miles upstream from the mouth.
This is of special concern because in that area there is a
greater possibility of the bacterial contamination coming from human
sources. The area is also
near to shellfish beds.
Ø
To
meet public health-based water quality and shellfish harvest
standards, reductions in bacteria are needed in the following areas:
Matriotti
Creek
the
irrigation ditch that enters the Dungeness River one mile upstream
from the mouth
the
Dungeness River between 0.1 and 0.3 miles upstream from the mouth
Meadow
Brook Creek and Slough
Cooper
Creek
Golden
Sands Slough.
Local
entities and state agencies are working together to address water
quality issues and shellfish closures in the lower Dungeness
watershed. Ecology’s
water quality study has been used to update and refine Clallam
County’s Clean Water Strategy.
Clallam County, the
Jamestown S’Klallam Tribe, Clallam Conservation District, and others
helped to write the strategy as part of the formation of Clallam
County’s Clean Water District, adopted by ordinance in June 2001.
The
strategy is the core of the Water
Cleanup Plan for Bacteria for the Lower Dungeness Watershed.
It describes activities recommended to help reduce bacteria
levels, the responsibility and authority of the responsible public
entities, and funding sources and needs. It also proposes a cleanup
schedule.
In developing the
strategy, the workgroup considered all sources of feces from warm
blooded animals, including
humans, domestic animals, and wildlife. Wildlife
sources are a concern. However,
options for addressing this waste are limited.
The strategy primarily
addresses human-influenced inputs such as animal keeping practices,
pet waste, and on-site septic systems.
By cleaning up the human side of the bacteria contributions,
most of the water quality concerns may
be alleviated. If it is not enough, options for managing
areas of high wildlife concentrations in the watershed can
be explored. Technology, such as “mycoremediation” (a
technique in which mushrooms are used to “eat” bacteria), may be
useful in removing wildlife
waste.
The
updated strategy, along with supporting information from the water
quality study, will be available for public comment from April 15 to
May 13. We are interested
in your comments on the cleanup activities and schedule proposed in
the Summary Implementation Strategy, as well as additional suggestions
you may have.
