Water Filter to Reduce Beach Closings?

Beaches throughout the Great Lakes have long been plagued by bacteria that can make people
sick. For the first time in the region, researchers will test a filter designed to guard a swimming
beach from hazardous bacteria. The Great Lakes Radio Consortium’s Annie MacDowell reports:


Next April, the Chicago Park District plans to install and test an eighteen-hundred foot-long
floating filter system. A similar technology was used to protect fish hatcheries during the 1989
Exxon Valdez oil spill. And studies show the system has been successful in decreasing bacteria
levels at New York beaches.


Jim Miner is the Executive Vice-President of Gunderboom Incorperated, the company that makes
the filter. He says the filter will surround the beach like an underwater curtain:


“What is underwater, the fabric curtain, will not be seen by the swimmer and it is a non-intrusive,
fabric-filtered barrier that goes from the surface to the bottom and it’s anchored there and
protected so that only filtered water can get into the swimming area.”


The technology could reduce swimming bans at city beaches.

Stronger Invasive Law on the Horizon?

Congress is considering legislation that would create national standards for fighting invasive species. The Great Lakes Radio Consortium’s Jonathan Ahl reports:


Two Republican house members and a Democratic Senator are sponsoring the legislation. If the bill passes, it would create nationwide standards designed to keep foreign species from overrunning native plants and animals.


The legislation would extend the ballast water exchange standards currently in effect in the Great Lakes to the entire country. It would also improve screening protocols for importing plants and animals.


The bill also includes some funding to test new technologies. They include using chlorine, filters, and ultraviolet lights to kill off foreign species at some entry points to U.S. waterways.


A staff member for Michigan Senator Carl Levin says the bill is intended to be a first step toward developing international rules to stop the spread of invasive species. The lawmakers plan to introduce the bill when they return from their August recess.

Screening Out Exotics

Efforts to find new technology to stop the spread of exotic speciesentering the Great Lakes continue, even as some worry that a virus-basedthreat could make its way here. The Great Lakes Radio Consortium’s MikeSimonson has more:
