21
streams at risk for fish kill algae

Mon creeks on watch list

The
West Virginia Department of Environmental Protection (DEP) fears 21 other state
streams have conditions conducive for growth of the same Dunkard Creek fishkill
algae.
During an interim meeting last week, the Joint Legislative Oversight
Commission on State Water Resources also learned:
The golden algae toxins
killed the fish and mussels, but no one yet knows how the algae got there.
Legislative action may be needed to control the conditions that could lead to
future outbreaks. The puzzle has to be solved before fish can be returned to
Dunkard Creek.
As investigators learned what makes the
algae thrive, particularly the total dissolved solids (organic and inorganic
minerals, salts, metals and other matter), Scott Mandirola of the West Virginia
DEP said, they began asking, “What other streams are potentially affected by
this?”
They compiled a list of 21 waterways of about 10
miles or more in length that had the right “conductivity,” a measure of the flow
of electric current that reflects TDS levels.
“Those
streams are now identified as being potentially at risk if these algae were
allowed to spread,” he said.
Frank Jernejcic, District 1
fisheries biologist for the West Virginia Division of Natural Resources (DNR)
identified seven of them, besides Dunkard, as being in this area — the
Monongahela River drainage basin: Buffalo Creek, Elk Creek, Bingamon Creek, Paw
Paw Creek, Pyles Fork, Indian Creek and Dents Run.
Jernejcic told the commission that the algae outbreak has
eliminated about 99 percent of the fish along the 30-mile stretch of Dunkard
Creek in West Virginia.
The kill destroyed 18 species of
fish and 14 species of mussels — all the mussels in the creek — he said.
He didn’t have information on the extent of the fish kill
in the Pennsylvania portion of the creek. The Pennsylvania DEP referred
questions to Eric Levis, spokesman for the Pennsylvania Fish & Boat
Commission, who did not return calls placed over the course of two days.
Investigators
search for algae source
Mandirola
told the legislators that the golden algae, known as Prymnesium parvum, first
appeared in Texas in 1985. It mainly kills fish and, unlike red tide, isn’t
harmful to humans.
Experts analyzed some of the dead fish,
he said, and confirmed algae toxins killed them — affecting the livers and gills
most severely.
Investigators know the algae likes brackish
water, and that Dunkard has the conditions — the right acid levels and high
total dissolved solids (TDS), including sulfates and chlorides (salt) — that
favor golden algae growth.
But, Jernejcic said, “why it’s
there, how it got there and what caused it to reach the levels ... that would
have caused the fish kill” is still a mystery.
The golden
algae is a symptom — they haven’t gotten to the cause.
“We
believe with confidence that it’s golden algae toxins that are killing the
fish,” Mandirola said. “They like the environment that’s there. We need to see
what we can do about the environment.
“They’ve not come up
with a clean, easy way to get rid of it,” he said. “The best approach is to
learn how to live with it and learn how to control what it doesn’t like. If you
can make the environment unfavorable ... they won’t be able to produce the
toxin, they won’t be able to bloom and they won’t cause the problems.”
Helen Humphreys, spokeswoman for the Pennsylvania DEP,
said her agency is continuing to collect information so it can come to its own
conclusion about the cause.
“The algae needs a brackish,
salty environment to thrive,” she said. “Dunkard Creek is a freshwater stream,
but high TDS levels have made it salty. So, where is it coming from?”
Investigators said they think it may possibly be linked to
mine drainage, which is associated with high TDS levels, especially during low
flow times, when rainwater isn’t diluting the discharge.
Tests show high TDS levels in the Dunkard as far upstream
as St. Leo, near the mouth of the South Fork tributary, southwest of Wadestown
near the Marion County border. There is a mine drainage pool in this area, and
at a point above a beaver dam, above the drainage pond, the algae cell count
drops dramatically.
And other mine pools drain into the
Dunkard in both states.
Legislation
may be needed to get solids under control
Getting
TDS levels under control is part of the answer, and legislation may be needed,
several people said.
“How long are we going to keep going
before we say, ‘Let’s draw a line in the sand?’ ” Jernejcic said after the
meeting.
Asked if it would require legislative action, he
said, “I suspect.”
Dr. Duane Nichols, a water expert,
retired WVU professor and member of the Upper Monongahela River Association,
gave his opinion to the commission: “We have called for water quality standards.
... We need a statewide standard for total dissolved solids.”
Delegate Tim Manchin, D-Marion and co-chairman of the
commission, said legislation may involve “a couple avenues.”
One could be adopting overall stream quality regulations
regarding factors related to chlorides (salt) and TDS. Pennsylvania already has
some TDS standards, he said.
Another could involve
implementing some treatment measures for mine drainage.
“How much discharge do you allow?” he asked.
Beyond that, he said, “At what point does this start
having an impact on our economic community?”
Right now, he
said, commissioners are trying to bring themselves up to speed so they’ll be
ready if and when the DEP brings forth proposed legislation.
Pennsylvania and West Virginia DEP officials have credited
CONSOL Energy with being cooperative during the investigation. Consol has ceased
discharges from mine pools along the creek while investigators study the cause.
Humphreys said the Pennsylvania DEP believes discharge
from the Blacksville No. 1 and Blacksville No. 2 mines could have contributed to
the high TDS and chloride levels, according to a letter the department sent to
CONSOL dated Oct. 7.
In the letter, the Pennsylvania DEP
requested information about the various mine pools in the Dunkard Creek
watershed and how they are connected.
The Pennsylvania DEP
also requested copies of all of CONSOL’s discharge monitoring reports for the
Blacksville No. 2 mine and copies of the company’s permits and permit
applications, among other things.
Humphreys said the
Pennsylvania DEP would review the information from CONSOL, once the company sent
it.
The Pennsylvania DEP also sent a letter to the U.S.
Environmental Protection Agency this month, asking the agency to revoke an
Underground Injection Control permit that allows CNX Gas Co. — a subsidiary of
CONSOL — to inject wastewater into the Morris Run Borehole at the inactive
Blacksville No. 1 mine.
The permit allows CONSOL to
dispose of up to 150,000 barrels per month of coal-bed methane wastewater, which
contains up to? 25,000 milligrams per liter of TDS, according to the letter.
EPA spokesman David Sternberg said the agency is
evaluating the letter and is preparing a response to it.
Sternberg said he did not know when the response would be
mailed.
CONSOL voluntarily stopped injecting the
wastewater into the borehole Oct. 2.
