Beowulf by panniuniu


									        Hidden Evil before hidden evil…At night that lake Burns like a torch. …
     A stag with great horns, though driven through the forestfrom faraway places,
                  prefers to die on those shores, refuses to save its life

                               In that water. “Beowulf”

                              A Resource Despoiled

 The Environmental Protection Agency (EPA) estimates that approximately one third
of all of the waters assessed by individual state agencies are unsafe for swimming fishing
and drinking.

 As of 1997, 47 states have issued freshwater fish consumption advisories after
evaluating the extent of pollution in their lakes and rivers.

 Advisories identify 45 contaminants in lakes and rivers including mercury, PCB's,
chlordane, dioxin, and DDT.

 More than 100 types of human pathogenic viruses may be present in fecal-
contaminated waters. Giardia, an intestinal parasite that is difficult to remove from
source water, is found in waters receiving urban pollution.

 The use of disinfectants such as chlorine and algaecides such as copper sulfate, can
pose a health threat to humans and aquatic organisms. Trihalomethanes, a byproduct of

chlorination, are potential human carcinogens.
