Sometimes a problem can be turned into an opportunity to teach
the next generation. That's what's happened near Latrobe, Penn.,
where more than 50 individuals, businesses and agencies have formed
a coalition to clean up a polluted stream, and in the process, also
set the stage for a new teaching resource to educate children and
young people about pollution solutions.

Four Mile Run is a small stream that feeds into Monastery Run,
a tributary of the Loyalhanna Creek. Four Mile Run's bed is stained
orange from pollution, like many mine drainage damaged streams,
and is the beginning point of contamination that eventually reaches
the Loyalhanna Creek. Upstream of where it connects with Monastery
Run, the Loyalhanna is a popular fishing spot. Below, however, the
Loyalhanna becomes progressively more polluted from mine water.
The polluted mine water enters Four Mile Run from "The Bubbler,"
a manmade bore hole draining the mine below at a rate of 300 to
550 gallons a minute. This discharge has a high concentration of
iron in it, which mixes with oxygen in the air to create iron oxide.
Because the area contains limestone rocks, this discharge isn't
particularly acidic, since the limestone neutralizes the acid much
the way antacids help with human stomach acidity. Still, it causes
problems.

In 1993 the Loyalhanna Mine Drainage Coalition began a collaborative
effort to treat the abandoned mine drainage coming from Four Mile
Run. The tool of choice was a passive approach using a system of
wetlands.
Water was piped from the Bubbler using only its natural hydraulic
pressure to move it the 1,600 feet upstream to the first wetland
cell, where it begins the cleaning process. Various subsequent stages
use natural tools like cattails, a dominant wetland plant, to slow
down the water flow. Slowing the water gives the iron oxide more
time to settle to the streambed instead of being carried farther
downstream.
In 1999, the effort expanded in a new direction. St. Vincent College,
a member of the coalition and owner of a significant portion of
the land involved, organized an environmental education center to
use the site for teaching and research purposes. The center offers
programs for students from kindergarten to college, as well as the
general public.

The Loyalhanna Mine Drainage Coalition created a wetlands
complex that acts to cleanup the polluted water.

"Our program revolves around the Monastery Run Improvement Program,"
said Angela Check, the environmental education center coordinator.
"We started in '93 when we started collecting baseline data using
AmeriCorp volunteers. When we did that, we always had it in mind to
do environmental education.
"What's been unique about the project is that we sort of have
this niche with mine drainage and wetlands. We currently have from
3,000 to 5,000 (if you count high school) students per year visit
the center."
This isn't just a field trip for the kids though. And while it may
be fun, it's not a lark either. There's preparation involved for
both the students and their teachers in order to get the most from
the experience.
"We bring the teachers in," Check said, "and they
go through a day long training session to introduce them to coal
mining and how it creates mine drainage. We give them guided tours
and teacher manuals, and pre-activity kits that they can use to
work with the students before they come in.
"When the school children come in they're introduced to coal
mines and how they work. The students are then broken down into
small groups and visit four stations at Monastery Run. They get
a hands-on experience where they do a scavenger hunt and water testing
with field kits where they test for iron and sulfates."
Each visit lasts about two hours. Teachers and students then leave
with post-visit educational materials to follow up on. There is
a $3.00 charge per student.
"At the end, we also play a wetlands simulation game,"
Check said. "We draw out the system on the parking area, and
the students dress in costume as water molecules and go through
an obstacle course playing different roles. At various points some
of them will be told to drop the iron molecules they're carrying
to simulate the effects of the system."
