MONONGAHELA – The state Department of Environmental Protection is
taking water samples downstream of a large orange streak on the
Monongahela River that developed in the Monongahela area Saturday.
A large orange streak on the Monongahela River developed in the
Monongahela area Saturday. A DEP spokesman said the discoloration
was caused by water from an abandoned mine pool.
The discoloration is caused by water from an abandoned mine pool
draining into a pipe that pours into a stream leading to the river
in Forward Township, Allegheny County DEP spokesman Neil Shader
“The water is thought to contain iron, aluminum and manganese,
which accounts for the orange discoloration,” Shader said.
He said the Allegheny County Health Department and public water
intake systems were notified, even though the water providers have
systems in place to remove the contaminants.
