State Seeks Help from Washington on Mon Discharges

A year after murky water quality problems first surfaced in the Monongahela River, Pennsylvania is asking the federal Environmental Protection Agency to set new, tougher pollution limits for the interstate waterway and public drinking water source.

According to Pennsylvania Department of Environmental Protection Secretary John Han ger, the state has issued orders limiting discharges of total dissolved solids, or TDS, in the Mon River and has started the lengthy state process of drafting new regulatory controls, but West Virginia hasn't taken similar steps to address the problem.

As a result, levels of the microscopic contaminants in the river where it leaves West Virginia and flows into Pennsylvania spiked to almost 600 milligrams per liter early this month, exceeding the federal and Pennsylvania secondary maximum contaminant levels of 500 milligrams per liter. West Virginia does not have such a standard but is reviewing whether to enact one.

"We're not satisfied with the response we've received from West Virginia and are engaging the EPA," Mr. Hanger said, "because at the end of the day, without federal involvement, we may not get the kind of cooperation needed to solve this problem. I personally have concerns that the posture of West Virginia on this matter is not aggressive enough.

Mr. Hanger, who complained that West Virginia had not shared much data on TDS sources and amounts, asked the EPA to intervene. And he said Pennsylvania has started the federal Clean Water Act process to have the river classified as "impaired."

Such a determination would allow the EPA to establish a watershedwide Total Maximum Daily Load limit, or TMDL, which is a calculation of the maximum amount of a pollutant that a body of water can receive and still safely meet water quality standards. If a load limit is established, the cumulative discharges from public utilities, industrial facilities and other point sources would be restricted.

Pennsylvania is expected to submit a package of river flow data to the EPA supporting the "impairment" determination by April of next year.

Not all the TDS loading is occurring in West Virginia, Mr. Hanger said, but so much is being discharged into the Monongahela River there that when the river flow is low in late summer and fall, its ability to dilute the dissolved solids to acceptable concentrations is completely used up by the time it reaches Point Marion, along Pennsylvania's southern border in Fayette County.

Sources of dissolved solids include sewage treatment plants, power plant scrubber and coolant water, storm water runoff, abandoned mine drainage, a host of industrial activities and wastewater from oil and gas drilling, especially the millions of gallons produced by deep wells tapping into the Marcellus shale gas bed.

For the past year, Pennsylvania has restricted the amount of wastewater from those deep gas drilling operations that sewage treatment plants can accept to no more than 1 percent of their total water discharges into the river.

West Virginia has only recently urged treatment facilities to limit intake of well waste water. And officials there said the sewage treatment plant in Clarksburg, the only such facility in the state that was permitted to accept well drilling waste water, stopped last month.

According to the West Virginia Department of Environmental Protection, most Marcellus shale well waste waster is disposed of by injecting it deep underground. Scott Mandirola, director of West Virginia DEP's Division of Water and Waste Management, said West Virginia will "cooperate fully" with Pennsylvania and the EPA to develop a TMDL standard for the Mon.

Last fall and winter, TDS levels in the river hit 800 milligrams per liter -- significantly exceeding the Pennsylvania and federal secondary drinking water standard -- causing bad tasting and smelling drinking water from public utilities that draw water from the river and problems for industrial users.

The pollutant levels have not been as high this year as last, but monitoring by U.S. Steel at its Clairton Coke Works water intake has shown recent increases. Erin DiPietro, a U.S. Steel spokeswoman, said the pollutant levels have not impacted operations, but the company will continue to provide the DEP with monitoring data.

For most people, high TDS levels do not make tap water unsafe to drink. But at least one individual allergic to sulfates, a component of TDS, broke out in hives last fall.

"It needs to be mentioned that people with certain allergies can have problems," said Marie Miller of Upper St. Clair, whose 11-year-old son, James, developed itchy hives for two weeks. "It's not a life-threatening problem, but I called our water company, Pennsylvania-American, and they said it will probably get worse again in the fall."

Water treatment plants -- there are 11 public water suppliers on the 70 miles of Mon flowing south to north in Pennsylvania -- are not equipped to remove TDS, a measure of all elements dissolved in water, including carbonates, chlorides, sulfates, nitrates, sodium, potassium, calcium and magnesium.

Public water suppliers using the river as a source include Pennsylvania-American Water Co., which is the largest with 86,000 customers in southern Allegheny, Fayette and Washington counties, Charleroi Municipal Authority, Belle Vernon Municipal Authority, Washington Township Municipal Authority, Newell Municipal Authority, Tri-County Joint Municipal Authority, Southwestern Pennsylvania Water Authority, Carmichaels Municipal Authority, Masontown Water Works, East Dunkard Water Association and Dunkard Valley Joint Municipal Authority.

TDS levels in the Mon River have been lower since the beginning of August due to increased river flows caused by recent rains. But the Pennsylvania DEP expects them to fluctuate through, and has recommended that customers with concerns should use bottled water to drink and prepare food when TDS levels are high.

"It's not an issue that will be solved in a couple of months," Mr. Hanger said, adding that Pennsylvania's new regulations for dissolved solids probably won't be in place until the end of 2010. "Ultimately, it will take federal involvement because it's a multi-state problem and we don't control what's going on in West Virginia."
