, the abandoned diggings will be put to new use. Fly ash from the dirt collectors on the smoke stacks at Colfax and Duquesne Light's new $100 millon Cheswick station will be mixed into a slurry that'll be pumped into the underground voids. "If we disposed of the fly ash at an open air dump, the wind could blow it around," said a spokesman for Duquesne Light. "This way, it travels to the disposal site in a closed system of pipes, then goes underground doe safe, clean storage.
Water Pumped Back
The water in the transporting slurry will be pumped back out of the mine after it has delivered its load. Il'll be treated at a new $300,000 water treatment plant that will remove impurities. The "cleaned" water finally will be discharged into Little Deer Creek. About five millon gallons of water will be treated each day, including the normal drainage from the worked-out mine. Henceforth, Duquesne Light will rely mostly on coal produced by its Warwick Mine in Greene County to keep its electric generating plants going.
Harwick Mine opened in 1901. Duquesne Light acquired
it in 1940.
|The monument at the Harwick Miners mass
grave site, in Springdale, PA, ca.2004. The monument is located near
the presentday coal handling area of the Cofax Power Plant. I tried
to locate the monument in 2010, the location is in a construction parking
lot area for the rebuilt power plant, and could not be located, not sure
if it was moved or covered over.

Update on the Harwick Miners Memorial
It is easy to visit the cemetery by entering the power station
driveway, located off Freeport Road, ironically at the site of the trestle
that carried coal from the Harwick mine via the Cheswick & Harmar Railroad
to the power station coal yard, and after stating your business to the guard,
proceed directly to the site.

Springdale, PA, ca.2004, a couple of miles from the site of the Harwick Mine,

Disaster. Adolph Gunia father and brother are buried at his mas grave
