Boatyard Stormwater Treatment Technology Study
Taylor Associates, Inc. Northwest Marine Trade Association;
Puget Soundkeeper Alliance; Washington State Department
of Ecology.
March
2008 Final Report
EXECUTIVE
SUMMARY
Project Overview. This report summarizes the methods
and results of data collected from a study of three
stormwater treatment technologies that were installed
at three boatyards around Puget Sound. These three
technologies include (1) the StormwateRx Aquip™
(Aquip) installed at the Port of Edmonds Boat Workyard,
(2) the Siemens Water Technologies Wastewater Ion
Exchange (WWIX) Services installed at the Canal Boatyard,
and (3) the Water Tectonics, Inc. Wave Ionics™
Electro-Coagulation System Treatment (Wave Ionics)
installed at CSR Marine. Each technology was installed
to treat
runoff from approximately one to two acres of predominately
impervious surfaces where boats are maintained and
serviced. The Northwest Marine Trade Association (NMTA),
Puget Soundkeeper Alliance (PSA), and Washington State
Department of Ecology (WSDOE) collaborated on the
study to assess the ability of the different technologies
to remove contaminants, especially metals and TSS,
from the boatyards’ stormwater runoff.
A steering committee comprised of members and representatives
from the NMTA, PSA and Ecology was put together to
oversee the study.
Technology Description. This section
includes brief descriptions of the three technologies
evaluated. More complete descriptions of each technology
can be found at their respective websites which are
listed below.
(1) StormwateRx® Aquip™ (www.stormwaterx.com).
The Aquip is a passive adsorptive filtration technology
designed specifically for reduction of stormwater
pollutants such as turbidity and metals from industrial
sites, including boatyards. The overall treatment
capacity of the Aquip system installed in the Edmonds
Boat Workyard was 5.4 gallons per minute (gpm).
(2) Siemens Water Technologies, Inc. Wastewater Ion
Exchange Systems (www.water.siemens.com). The WWIX
utilizes ion exchange resins and other media to remove
specific ionic contaminants such as metals from stormwater
and
wastewater. The overall treatment capacity of the
system installed at the Canal Boatyard was 10 gpm.
(3) Water Tectonics, Inc. Wave Ionics™ Electro-Coagulation
System Treatment (www.watertectonics.com). The Wave
Ionics is an electro-coagulation system that uses
electrical current to coagulate particles by forcing
contaminated water to flow
between closely spaced metal plates across which an
electrical potential is applied. The
overall treatment capacity of the system installed
at CSR Marine was 50 gpm.
Sampling Approach. Rainfall and water
quality data were collected for seven storm events
for the Aquip and WWIX, and four storm events for
the Wave Ionics between November 2007 and February
2008. Influent and effluent samples were collected
at discrete flow rates of approximately 5.4 gpm for
the Aquip, 13.5 gpm for the Wave Ionics, and 10 gpm
for the WWIX using automated water quality samplers.
Samplers were programmed to collect grab and time-paced
composite samples, which were
submitted for total suspended solids (TSS) and total
and dissolved copper (Cu), lead (Pb) and zinc (Zn)
analysis.
Effluent Concentrations relative to discharge
criteria. Effluent data for the three technologies
were compared to discharge criteria set by the pilot
study steering committee for total and dissolved copper,
lead, and zinc. The steering committee did not establish
a discharge criterion for TSS. The effluent results
are summarized in the table below. The results generally
indicate the technologies performed better in the
removal of total and dissolved lead and zinc than
total and dissolved copper.

Table i Percent of effluent
results that met the discharge criteria.
Pollutant reduction. Percent pollutant
reduction for each parameter was calculated for the
three technologies. Total inflow was equal to the
total outflow for the Aquip and WWIX technologies
due to the design of the technologies and the sampling
approaches. As a result, the concentration reduction
is equivalent to a mass loading reduction for these
technologies on an event basis. Because of the large
size, detention volume, and resulting sampling approach
for the Wave Ionics the inflow was not equal to the
outflow.
The average percent pollutant reduction for the grab
and the composite samples for each technology are
summarized in the table below. Overall removal rates
ranged from 59.9 to 98.0 percent for Aquip, -92.6
to 97.8 percent for the Wave Ionics, and 75.8 to 99.0
percent for the WWIX.

SEATTLE: Oyster-loving Seattle Mayor Greg Nickels
proclaimed March 27, 2007 “Oyster Day”
to honor the 18th annual Anthony’s Oyster Games
& Shucker’s Ball*. In a day of contests,
fun, food and drink, 600 celebrants at the sold-out,
popular, rite-of– spring event consumed 30,000
oysters while raising $42,000 to support the Puget
Soundkeeper Alliance’s clean water programs.
Greeting revelers and joining in the fun at the event,
Mayor Nickels commended Anthony's for generously sponsoring
these games
dedicated to bringing celebrities, elected officials,
local restaurants, the oyster industry, clean water
organizations and the public together to have fun
while emphasizing the importance of preserving oyster
habitats and the quality of Puget Sound waters. Seattle’s
Mayor also had a few unflattering words to say about
the U. S. Olympics Committee’s “cease
and desist” order regarding the use of “Olympics”
in the event known as Anthony’s Oyster Olympics
for 17 years.
In the event’s traditional event “Oystertainment”,
oyster and fun-loving Seattle celebrities rocked the
house with upbeat, spirited works created especially
for Anthony’s Oyster Games. Several songs boosted
the Oyster’s 2000 year-old reputation as a stimulant
to love and other’s poked fun at the U.S Olympics
Committee’s stingy “Olympics” attitude.
Northwest Cable News anchor Greg Copeland bested 12
area celebrities in the popular Celebrity Oyster Slurp
slurping 10 oysters off the shell, no hands, in 7.2
seconds. KMPS’s “Tall Paul” Fredricks,
came in second in 7.9 seconds with Evergreen State
College President, Les Purce taking third. Copeland
will represent Seattle in the National Oyster Slurping
Finals at Shaw’s Crab House’s Royster
with the Oyster Festival in Chicago on October 19th.
Twenty restaurant teams including, Joe Fortes from
Vancouver BC, competed in oyster shucking, oyster
identification and wine identification and for the
coveted Oyster Gamrs team trophy. David Leck from
Elliott’s Oyster House was the top shucker with
Nhi Luong from Elliott’s second and Chris Field
from Joe Fortes third. Shuckers are judged on quality
of presentation as well as speed. In five heats, the
Competition tests skills in opening five species of
oysters: Olympia, Pacific, Kumamoto, European Flat
and Eastern oysters. In the world’s most challenging
shucking competition, Leck
impressively bested the area’s top shuckers
in each of the five heats on the way to way to his
Anthony’s Oyster Games shucking medal.
Tara Brayman, Elliott’s Oyster House, earned
the top trophy in Oyster Identification. Contestants
determine the generic common name, Latin name, Market
name and growing method of 12 types of oysters. Marcia
Sullivan of Elliott’s took the silver and Charles
Broadwin, Metropolitan Market, won the bronze.
Contestants in the Oyster Wine Identification Competition
identify, in a blind tasting, 10 oyster-compatible
wines by varietal, producing country or state and
winery. Tom Arthur of Elliott’s Oyster House
won the gold with Doug King, Metropolitan Market and
Andy Gross, Anthony’s Des Moines taking second
and third respectively.
Elliott’s Oyster House, claimed the prestigious
team trophy, with Anthony’s Des Moines taking
second and third going to the second team from Elliott’s
Oyster House.
David Leck, the ace shucker from Elliott’s,
and Doug King, the wine expert from Metropolitan Market,
were inducted into Anthony’s Oyster Games Hall
Fame. Hall of Fame inductees qualify by earning individual
medals in three different years.
Jeff Florek of Taylor Shellfish Farms brought in the
big oyster to win the $500 prize in the Third annual
"Washington's Largest Oyster Contest". It
wasn’t longest and it wasn’t the widest
entry, but Florek’s Oyster Bay find was the
heftiest over all. The winning mollusk measured 9.5
inches long, 5.5 inches wide, 3.75 inches deep and
weighed 3.61 lbs. Ekone Oyster Co. from South Bend
landed the second and third largest oysters.
The 2007 Anthony’s Oyster Games & Shucker’s
Ball Lifetime Achievement Award for enduring contribution
to Northwest/Seattle oyster culture was bestowed on
Seattle Post Intelligencer columnist Susan Paynter
for her longstanding passion for the Oyster and her
enthusiastic participation in the event from the beginning.
Paynter
has participated as a fashion contestent, a Celebrity
Oyster Slurper and composes a spirited original poem
every year for “Oystertainment”. Each
year on the last Tuesday in March Anthony's-Shilshole
closes it doors to the public for the Oyster Olympics
and donates its space, food and labor. Additional
donations come from over 30 oyster, wine and ale vendors.
Since 1990, the event has raised $480,000 for the
Puget Soundkeeper. Anthony’s Oyster Games and
Shucker’s Ball was conceived as a way to bring
the community together for a day of fun, food and
beverage bring together to have fun celebrating our
local oysters while drawing attention to importance
of clean water. "Clean water is essential to
all of us who love this area,” says Anthony's
owner Budd Gould.

*After 17 years, Anthony’s, sponsor of the popular
clean water fundraiser formerly known as Antlhony’s
Oyster Olympics, received a “cease and desist”
order from the U.S. Olympics Committee regarding the
use of “Olympics” in Oyster Olympics.
While
organizing the 2007 event, a public contest was held
to find the new name, “Anthony’s Oyster
Games and Shucker’s Ball”.
