Significantly
reducing pollution from human and animal waste and other sources of pathogen
and nutrient pollution is one of eight key
objectives established in law for the Puget Sound Partnership’s 2020 Action Agenda.
What’s
the problem?
Human and animal waste contains high levels of nutrients (such as nitrogen, carbon and phosphorous) and pathogens (such as harmful bacteria and viruses). These pollutants
can enter
Puget Sound
waters from a variety
of sources including:
-
Septic systems
Focus on high-risk areas.
-
Washington State
Department of Health is working with local governments, tribes, and
others on water quality projects to restore 12 commercial and recreational areas that are degraded or threatened.
-
The departments of
Health and Ecology are monitoring
60 swimming beaches with the goal of increasing the percent of
beaches that meet bacteria standards.
-
Design, permitting
and start of construction of a
new wastewater treatment plant will take place in the 2007-2009
biennium for the Squaxin Tribal Village in south Puget Sound.
-
Sewage treatment plants
-
Runoff from farms with livestock
-
Fertilizers
-
Waste discharges from boats and ships
-
Pet waste left on the ground
Nutrients. Excess
nutrients can disrupt the functions of a healthy ecosystem. For example,
too much nitrogen in marine waters can speed up and multiply the growth
of phytoplankton (microscopic algae). As the phytoplankton die and decompose,
they sink to the bottom and use up oxygen in the process. During this cycle,
fish, crabs, shrimp and other marine organisms can die from lack of oxygen.
The problem of low dissolved oxygen came to light in
Hood
Canal
in 2002 when
marine life washed up on the shores, having essentially suffocated from
lack of oxygen. Other areas of
Puget Sound
,
including portions of South Sound and Whidbey basin, appear to be sensitive
to excess nutrients.
Pathogens. Human
and animal wastes are the source of most pathogens in
Puget
Sound
. Viruses and some bacteria and parasites can make people
and animals sick.
Pollution from pathogens, which is
commonly measured using fecal coliform bacteria, has been the cause of widespread shellfish closures throughout
Puget Sound
.

What’s
being done to reduce pollution from human and
animal waste?
Efforts to reduce pollution from human and
animal waste are happening throughout the Sound. State, local and federal
agencies, tribes, non-profit organizations, watershed groups and businesses
are the main players. The following are some highlights of work underway:
-
Improve state
agency coordination to get better results.
-
Washington
State
Parks
and Recreation Commission is improving and adding boater pumpout facilities throughout
Puget Sound
.
State Parks is also engaging in a boater-education campaign with the goal of increasing by the amount
of boater waste collected at pumpouts.
The agency is upgrading, repairing
or replacing new sewage facilities to bring them into compliance
with Ecology and Health operating permits.
In addition, State Parks is installing
more pet-waste disposal stations to reduce the amount of pet waste
entering our waters.
-
The Puget Sound Partnership and the state departments of Health, Ecology
and Agriculture are updating their interagency guidance agreements
to improve how they coordinate
responses to shellfish closures and threatened shellfish areas.
-
Support effective and innovative
regulatory and non-regulatory approaches.
-
Agriculture is working with dairies and concentrated
animal feeding operations in
Puget Sound
to increase compliance with state and federal
water quality rules with the goal of reducing discharges and the
need for follow-up inspections.
-
Washington State Conservation Commission is working with local conservation
districts to complete hundreds of conservation
plans and put practices on the ground to prevent pollution.
-
The U.S. Environmental Protection Agency will issue general permits
from the National Pollution Discharge Elimination System (NPDES) for tribal and fish hatchery wastewater discharges.
-
Strengthen the ability of local
governments to carry out comprehensive control programs.
-
All 12 local health districts in
Puget Sound
are carrying out management
plans for their sewage programs, as approved by Health.
-
Six local health districts are developing
data to inventory and map onsite systems in priority marine areas.
-
Local
Puget Sound
health districts
and Ecology are managing loan
programs to help fix failing septic systems.
-
Educate and involve the public
to become stewards of the Sound.
-
The Puget Sound Partnership, WSU Extension, Washington Sea Grant Program
and State Parks are offering myriad
opportunities for the public to learn more about how to reduce
pollution from human and animal waste.
-
Washington Sea Grant Program and others are working with homeowners to change their fertilizing habits to
prevent runoff.
With help from Sea Grant, numerous shoreline landowners are growing shellfish that filter nutrient-rich phytoplankton from
the water. Many landowners will also be monitoring,
recording and mapping the varieties of macroalgae and shellfish
on their beaches.
-
Increase scientific understanding to guide management activities.
-
Ecology is leading the work on collecting monitoring data for a dissolved
oxygen and nutrient model for south
Puget Sound.
