Solutions for Lake Champlain Pollution The pollutants of Lake Champlain and what the community can do to preserve the lake Story by Tats Kasama Photo and figure courtesy of The Lake Champlain Basin Program State governmental
organizations, like the State
Department of Environmental Conservation, academic institutions, and
some private companies have begun efforts to improve and preserve Lake
Champlain's environment in the last decade. Now it's time for each
member of the community to take action. "I
was going to swim in the lake with my friend this summer, but my boyfriend
told me not to swim there because he was really concerned about the contamination." The Lake Champlain Basin Program has found eleven substances in Lake Champlain to be "High Priority Toxins," Dr. Robert Fuller, of Plattsburgh State University Colege, said. "Among those substances, two historical problems are PCB (Poly Chlorinated Biphenyl) and mercury because they are bioaccumulative."
PCB accumulates
in fat tissues while mercury accumulates in muscle tissues. Both can cause
health problems such as birth defects and cancer. New York and Vermont
have issued Fish Consumption Advisories that advise people to limit the
amount of, or not to eat, particular fish caught in Lake Champlain. However, "You can drink the (lake) water as much as you want," Fuller said. According to Fuller, fish consumption advisories were issued because fish spend their entire lives in the water, so "the larger the fish, the more likely to have accumulated PCB and mercury." Swimming in Lake Champlain, or drinking the water, is fine in terms of PCB and mercury.
The water quality of AuSable River is ranked fourth level from worst watershed, out of ten levels, in the New York State Clean Water Act Comparative Rankings. However, not only does Ausable River carry pollutants into the Lake but other watersheds do as well. The source of pollution that is discharged from a specific point, as Yoshida wondered, is called point source. If the source is a wide geographic area, it is called nonpoint source. Thanks to the improvement of sewage treatment and other facilities, now the percentage of phosphorus pollution from point sources around Lake Champlain has decreased from 20 to 10 percent. Stormwater
runoff, atmospheric deposition, and groundwater discharge are included
in nonpoint sources. Stormwater runoff carries any pollutants on the road
surface into the lake. These pollutants include de-icing chemicals, animal
wastes, oils that are thrown away improperly and so on. Atmospheric pollutants
can be carried by rain. Pollutants released from industrial areas in the
Midwest can also fall into the lake with acid rain. Pollutants in the
groundwater absorbed through ground surface can slowly flow to the lake.
If seals of hazardous waste site are not enough or are broken, the groundwater
will have critical damage. What actions would you suggest that an individual can make to solve this problem? |
