Puget Sound Initiative Intersects State Parks
Why are we building this treatment facility?
• State Parks is doing its part to protect Hood Canal
as part of the Governor’s Puget Sound Initiative
The Problem
• 11 aged septic tanks are in a flood plain
As a result, Hood Canal water may be negatively
impacted
The Solution
• TheParking
new wastewater
treatment process improves
lot A
groundwater quality
Why is nitrogen removal so important?
• Nitrogen is the main pollutant that causes low dissolved
oxygen levels in Hood Canal
• Septic tanks do not remove nitrogen
• Excess nitrogen causes algal blooms
• As the algae decays, it uses up dissolved oxygen in water
• Fish and other aquatic life need oxygen to survive

How it Works
• Physical Barrier Provides for Complete
Disinfection
How it Works
• Flat Sheet or Screen Technology (Ovivo)
Why We Use It
• High Quality Effluent - Water Reuse
•
•
•
Groundwater Recharge
Irrigation
Fire Suppression
• Smaller Footprint
• Great for Removal of Nutrients

State Parks has taken proactive steps to address
noise & water quality
Environmental Noise Impact Study
• An independent firm was hired to evaluate the daytime
and night average sound levels of the Green Hill Property,
and the current ambient noise levels at the adjacent
residential properties.
• Once the plant is in operation, a second evaluation will be
conducted to confirm that the new sewage facility is not a
disturbance and is within the character of the existing
sound levels.
State Parks has taken proactive steps to address
water quality & noise
Monitoring Wells
• Three monitoring wells have been have been installed at
the Green Hill Property.
• The wells were sampled on a quarterly basis for 1 year.
• The Intent was to establish existing water quality
characteristics.
Water Sampling
• Four residential water wells were also sampled on a
quarterly basis for 1 year.
• State Parks intends to re-sample these wells in the future.

Groundwater Water Quality Sampling
• Quarterly Sampling from Four Monitoring Wells and
Four Private Wells (June 2011 – June 2012)
