Scientists braved pouring rain and strong winds to collect more than
100 water and sediment samples from Huntington Harbour and Anaheim
Bay last week, launching the final phase of a two-part testing
process to determine the amount of pollution in the city’s harbor.
The study represents the most extensive water quality testing ever
to be done in Huntington Harbour, said Garry Brown, executive
director of Orange County Coastkeeper, a nonprofit environmental
organization dedicated to protecting the coastal waters in Southern
California.
The study is being directed and funded by the Santa Ana Regional
Water Quality Control Board, with the help of Orange County
Coastkeeper, which is providing the state agency with boats and
manpower.
“The theory is, if we can take that expense out of the equation,
then it will be easier for them to do the study,” Brown said.
To accurately assess contamination levels, data from the dry
weather season must be compared rainy season samples, said Pavlova
Vitale, planning director of the Regional Water Quality Control
Board.
Although the dry season data has been collected, scientists are
not releasing information until they can compare it to rainy season
data being collected now, Vitale said.
But Brown said that the overall water quality of samples taken in
the dry season was typical for harbors that have storm drains coming
in.
“There were no surprises,” he said. “The water had some excess of
water quality standards. There was nothing dire, but it shows we have
a lot of work to do.”
The historic study began in August of 2001, but the wet season
phase was put on hold for a year due to a shortage of rainfall.
The wet season study must be done after a hearty rain, since the
primary source of contaminants is carried in storm water runoff, said
Richard Gossett, laboratory director of CRG Marine Laboratories,
where the data’s chemical analysis is being performed.
“This is going to answer a lot of questions,” Brown said.
Of the several channels that drain into Huntington Harbor, the two
largest are the East Wintersburg Channel and the Bolsa Channel. Water
and sediment carried in the channels often contains contaminants such
as pesticides from lawns, nitrates from fertilizers, trace metals
from brake linings and diesel exhaust.
By the end this second phase of the study, scientists will have
gathered 60 water and 60 sediment samples from the harbor and the
bay. After collecting water samples, scientists began the arduous
process of collecting the sediment.
Using a tool called a Van Veen, the sediment was removed from the
top layer of the harbor floor and deposited into a large bucket
covered with a wooden grate, designed to break up the material to
facilitate the sorting process.
On the boat, the scientists sift through the sediment and extract
small worms, clams, shrimp and other organisms, which are then sorted
into phyla and later tested for toxicity in the lab.
“The sorting is really tedious,” marine biologist Karin Wisenbaker
said. “It involves taking anything alive -- shell hash, animals --
and identifying it.”
The samples will be sent to biology and chemistry labs, where
contaminants will be measured and organisms further identified.
Gossett estimates it will take as long as six months for results.
After determining contaminants, the next step of the process is to
try and pinpoint the source.
“If we’re finding brake lining, then we’ll start looking for a
junkyard,” Gossett cited as an example.
Once the data is complete, the state agency will often place
standards on the water body to enforce the amount of pollution
legally allowed in the water. These are known as “total maximum daily
loads.”
But Brown said that enforcing these standards can cost as much
$500,000 to $750,000. Instead, he hopes to eliminate the need for the
standards by focusing on educating the people and overseeing
different areas of the city to ensure that clean water guidelines are
adhered to.
“If we as a community can do some proactive things on our own, we
can reduce the need for [total maximum daily loads],” he said.
Brown suggested asking restaurant owners to stop hosing their
greasy mats into the water and urging people to quit dumping trash
and animal feces in the harbor.
The city is also devising a large-scale water quality plan. This
could include inserting storm scepters into storm drains to capture
and filter out the fine sediment that pollutants attach themselves
to, as well as installing units that would run alongside the flood
control channel and pull out trash.
Brown, who grew up playing on the beaches and in the waters around
Huntington and Newport harbors, is saddened by the changes he has
witnessed over the years.
“I remember the things I used to do here as a kid,” he said. “I
used to go out and dig clams. I could free dive and I’d come up with
a handful of abalone shells. They used to be very plentiful.”
Clams, barracuda and bonita also used to be abundant in the harbor
area but are no longer found in local waters.
“In 25 to 30 years, we have totally changed the whole ecological
health of our marine habitat,” Brown said, attributing the change to
pollution and population growth, which, he says, go hand in hand.
The Orange County Coastkeeper, founded by Brown in 1999, has grown
rapidly in the past four years. It is funded by grants, private
donations, private foundations and membership fees. It has its own
water lab and does bacteria sampling.
Brown is confident that change can be instilled on a local level.
“If the city becomes proactive, if the citizens become proactive,”
Brown said. “Then we can do a lot of things to improve water quality
and reduce the need to have [total maximum daily loads] imposed upon
us.”
