DEP, EPA Search for Golden Algae in Southwestern PA Streams

A golden algae bloom is believed to have wiped out the aquatic life in
Dunkard Creek, near the Pennsylvania/West Virginia border. Officials
are targeting at least 11 streams and the Monongahela River to see if
conditions are favorable to the algae.
The Pennsylvania DEP is keeping a close eye on streams in three
counties near the West Virginia border where the Dunkard Creek fish
kill began.
This week, the EPA and the Pennsylvania DEP are taking water samples.
Pennsylvania DEP Spokeswoman Helen Humphreys says the agencies are
trying to find out the extent of the golden algae contamination.
“We’ve looked at the streams, looked at the TDS levels in the streams,
to determine if the stream is more brackish or salty, which we know is
the preferred environment for golden algae,” she said.
The Pennsylvania DEP is looking at Monongahela River tributaries as far
north as Washington County, 30 miles south of Pittsburgh.
The Pennsylvania DEP has not found any evidence of dead fish in the
targeted streams.
They plan to conduct DNA testing of any algae found in the samples.
“This is a proactive effort,” Humphreys said, “we are looking down the
line seeing what possible impacts could be out there, so we can have a
chance of addressing it before there is a problem.”
The Pennsylvania DEP did not give a specific date when the samples
would be ready for release.
They say 750,000 Pennsylvanians use the Monongahela River as a water
source.
Humphreys says they are dedicated to eliminating all potential threats.
“There are multiple sources of TDS, so there’s not going to be a silver
bullet here,” she said.
“We’re not going to find one source and be able to eliminate it,” she
said. “We’re going to have to diminish it significantly across the
board, and that’s going to take time.”
In September, dead fish, salamanders and mussels were found on the
banks of Dunkard Creek in Monongalia County.
The creek’s water contained high concentrations of total dissolved
solids.
The West Virginia Department of Environmental Protection says a golden
algae bloom is the primary culprit of the fish kill.
It is the first documented case of golden algae in the Mid-Atlantic
states.
The West Virginia DEP says there are 20 other streams and rivers in
West Virginia that have conditions prone to an algae bloom like the one
at Dunkard Creek.
