Buffalo has become the first city in the Great Lakes region to pass a law aimed at curbing the amount of toxic chemicals entering the environment. As the Great Lakes Radio Consortium’s Joyce Kryszak reports, officials hope to accomplish this goal by changing their buying habits:


Every day, cities buy tons of office supplies and other products containing toxic chemicals. When these products are discarded, they eventually break down and sometimes leach toxins into the soil and water. The City of Buffalo recently adopted a policy to reduce purchasing of products containing Persistent Bio-Accumulative Toxins, or PBTs. But the decision could put more fiscal strain on a city that’s already in crisis. University at Buffalo Chemistry Professor Joe Gardella helped push for the law. He says a university study convinced the city it could both be fiscally and environmentally responsible.


“It doesn’t create additional exprenses, and, in fact, if one takes a long-term view of the fiscal impact, especially on the issue of creating markets for the recyclables that you’re trying to sell, there can be some really solid benefits to this,” said Gardella.


Under the new law, officials can only pay ten percent more for an alternative product. They say other costs will be reduced by eliminating some unneccessary purchases.

Breaking Down Groundwater Pollution

Scientists in the Great Lakes region are seeing good results from a new method that fights groundwater pollution. The Great Lakes Radio Consortium’s Erin Toner has more:


Researchers at Michigan State University are using a process that introduces microbial bacteria into contaminated aquifers. Over time, the microbes break down hazardous waste, usually from industrial spills. Before this new technology, the most common cleanup technique was called “air stripping.” That requires groundwater to be pumped to the surface, where toxic chemicals are basically blown out of the water and into the air.


Professor Mike Dybas says the new process doesn’t leave pollution in the ecosystem.


“It’s treatment actually occurring where the pollution is, and it is physically destructive of the contaminant. So at the end of the day, the contaminants are broken down into harmless end products.”


Dybas says the process could be used in any type of industrial or agricultural spill. He says since the microbes move with the water, cleanup could stretch for miles underground.
