State officials say the federal government is failing to do enough to stop invasive species of plants
and animals from damaging the environment and the economy. The Great Lakes Radio
Consortium’s Lester Graham reports:


The investigative arm of Congress, the General Accounting Office, surveyed state officials about
invasive species, the non-native plants and animals that sometimes stow away in shipments to the
U.S.


Many of the pests get loose in the wild and do a lot of damage, such as the zebra mussels that are
harming the ecosystems of lakes and rivers and emerald ash borers that are killing ash trees.


State officials say there are gaps in federal legislation, leaving no money or no requirements to
control the invasive species that have been here for a long time. State officials also say that
international trade agreements can make it difficult to regulate products that might harbor
invasive species because the trade agreements don’t address the problem.


The end result is often cheap imported goods that don’t consider or factor in the cost of the pest
that can be brought in with the cheap goods. Some state officials also noted that it would be more
effective to prevent the species from getting here in the first place instead of fighting them later.


For the Great Lakes Radio Consortium, this is Lester Graham.

State to Regulate Dishwashing Detergent?

The state legislature in Minnesota is looking at a bill that would restrict phosphorus levels in automatic-dishwashing detergents. Supporters say it would reduce harmful algae blooms in lakes and streams. If the bill passes, it would be the first state to make such restrictions.

The state legislature in Minnesota is looking at a bill that would restrict phosphorus levels in
automatic-dishwashing detergents. Supporters say it would reduce harmful algae blooms in lakes
and streams. If the bill passes, it would be the first state to make such restrictions. The Great
Lakes Radio Consortium’s Christina Shockley reports:


Phosphorus in detergents helps to clean dishes, but when the mineral ends up in lakes and
streams, it promotes algae blooms. Large algae blooms can kill fish and restrict sunlight to
bottom-rooting plants. In the 1970s, phosphorus was restricted in other types of detergents.
David Mulla is a professor in the soil, water, and climate department at the University of
Minnesota. He says that legislation did make a difference.


“We had a very large reduction in the amount of phosphorus that was being emitted to our waste
water treatment plants as a result.”


However, Mulla says dishwashing detergents are not one of the primary sources of phosphorus in
lakes and streams today. Detergent manufacturers say if they don’t use phosphorus, their
detergents might not meet some health standards. They also say a reduction won’t have any
environmental benefits. The bill is currently being discussed in the state legislature.

Will Legislation Ground Shipping?

Exotic species may claim another victim on the Great Lakes. If
proposed federal legislation passes, shipping industry experts say Great
Lakes commerce could be shutdown. The Great Lakes Radio Consortium’s
