Contamination is Common in U.S. Stream Fish

Scientists found mercury contamination in every fish sampled from 291 U.S. freshwater streams from 1998
The U.S. Government agency, U.S. Geological Survey
(U.S.G.S.), study found:
More than ¼ of the fish contained mercury levels above Environmental Protection Agency (EPA) recommendations
More than two-thirds of the fish contained mercury levels above EPA recommendations for fish eating
The U.S.G.S. Interior Secretary Ken Salazar stated: “This study show just how widespread mercury pollution has
become in our air, watersheds, and many of our fish in freshwater streams.”
Mercury is a neurotoxin that enters the environment primarily as air pollution
kicked into the atmosphere by industrial emissions and coal-fired power plants. The inorganic mercury then falls
to the surface in water, snow and dust. The mercury then is converted by plants and bacteria in the more toxic
form methylmercury. This more toxic type of mercury was found in the fish.
Previous studies of U.S. lakes and ocean waters found similar elevated mercury levels in the water and fish.
This was the first study of streams in the U.S.
The highest levels of mercury were found in the coastal “blackwater” streams of North Carolina and South
Carolina, Georgia, Florida and Louisiana. High levels of methylmercury were also found in some streams in the West
fed by areas where mining had taken place.
Mercury concentrates in animal tissue as it moves up the food chain, from algae, to insects to small fish and
larger predators. Largemouth Bass had some of the highest levels of mercury since they are at the top of the
in-stream food chain. Similar mercury concerns were found in largemouth bass in U.S. Lakes.
Toxic Water Solution
The main source of mercury contamination and mercury poisoning in humans comes from eating fish and shellfish.
If you have high levels of mercury in your body you should limit your consumption of larger species of stream,
river, lake and ocean fish.
You should test your body for elevated levels of mercury with the Comprehensive Urine Elements Profile from Genova Diagnostics or the Heavy Metal Screening Test.
If you have elevated levels of the toxic metal you can take oral chelation products for a couple of months and
lower the mercury levels.

You can decrease the need for coal-fired electric power plants by conserving electricity and switching to solar
and wind generated power.
