Sludge Again A Problem In Raleigh Creek

Superbugs thriving in wastewater treatment plants

by Kate Melville

In the first study of its kind, University of Michigan researchers have established that wastewater treatment plants are providing a perfect environment for the emergence of antibiotic-resistant superbugs that eventually end up in neighboring streams and lakes.

Simulating pharmaceutical and personal care product transport

Date:5/19/2009

MADISON, WI, MAY 18, 2009 Pharmaceuticals and personal care products (PPCPs) carried in biosolids (i.e., treated sewage sludge) may reach surface waters or groundwater when these materials are applied as fertilizer to agricultural land. During the high flow conditions created by land application of liquid municipal biosolids (LMB) the residence time of solutes in soil macropores may be too short for sorption equilibration which increases the risk for leaching. Physically based solute transport simulation models are widely used in environmental risk assessment for pesticides. These models may also be applicable for PPCPs when their physical and chemical properties and soil dissipation characteristics are available. However, these models do not account for non-equilibrium sorption in soil macropores. The model MACRO is one of the models used in environmental risk assessments for pesticides and may have potential as an environmental risk assessment tool for PPCPs.

Crap Happens: A Grist Special Report on How We Dispose of Our Poop


Three hundred million Americans head to the restroom multiple times a day. The amount of sludge produced staggers the mind—7 million dry tons per year and counting. And it’s not even just crap—it contains residues from everything else we put down the drain, from the detergent in your dishwasher to the chemicals used at the industrial plant down the street.

Can the United States continue to flush all that waste down the drain? Can Western-style sanitary practices be replicated throughout the developing world without breaking the natural water and nutrient cycles? And what if the answer is that each one of us needs to start taking more responsibility for where our crap winds up? It ain’t easy being green as it is, but even the most diehard enviros may not be ready to live under the same roof with a composting toilet.

Journalist Catherine Price, a contributing editor at Popular Science and a 2008 Middlebury Fellow in Environmental Reporting, gives a crap about crap. Over the course of three days, she’ll take Grist readers on a guided tour through the bowels of sewage. So grab some extra toilet paper and get ready for some straight poop on poop.

Day 1

* Sludge, farmer’s friend or toxic slime?
* Regulating biosolids

Day 2

* Businesses struggle to profit from sewage sludge

Day 3

* For some eco-pioneers, solving the sludge problems means getting their hands dirty

People are asking why a boy died after riding his bike over some sludge

A terrible waste gets long look

People are asking why a boy died after riding his bike over some sludge

Sunday, June 11, 2000

By Tom Gibb, Post-Gazette Staff Writer

OSCEOLA MILLS, Pa. -- The hurt is deeper because Tony Behun was so healthy -- an 11-year-old boy who loved life in the perpetual motion universe of an 11-year-old boy.

At her dining room table, his mother holds a stack of family photos, the chronicle of a young life.

There's the scrubbed, sandy-haired boy in his baseball uniform. The grinning youngster at creek-side, fishing. The tame dirt bike he rode across the mountaintops, where Centre and Clearfield counties come together.

Six years ago, life did what life isn't supposed to do to baseball-playing, dirt-bike-riding boys.

It slipped away.

On Oct. 12, 1994, Tony rode his dirt bike across hills coated in a sludge of treated sewage, the soup of waste and nutrients that the state lets strip miners use to coax life back into used-up mines.

In two days, he had a sore throat and headache. Six days later, he was in a hospital emergency room, his fever climbing, doctors calling a helicopter to fly him 110 miles through the night to Pittsburgh.

"Before the helicopter came, he was actually excited about the ride. He said, 'I'll get to tell the kids at school about this,' " said Tony's mother, Brenda Robertson. "Those were our last goodbyes, at Clearfield Hospital."

Tony died at 7:54 the next morning in Allegheny General Hospital.

Doctors determined he was killed by a blood infection, the bacteria Staphylococcus aureus. How he got it was a soul-searing question with no hint of an answer.

Until last year. Brenda Robertson happened to see a newspaper story about a state permit to spread sludge on another idle strip mine. The state Department of Environmental Protection was responding to talk that a local youngster had ridden through treated sludge and died of a bacterial infection.
