In 1997, the White River was listed as one of the
United States’ most threatened rivers.
Pesticides (
herbicides and
insecticides) are used extensively in the White River basin. Application of herbicides to
corn and
soybeans accounts for most of the use. The pesticides most frequently detected near the mouth of the White River during 1991–1995 were the herbicides
alachlor,
atrazine,
cyanazine, and
metolachlor. In 1999, the West Fork experienced a massive
fish kill that spread for with an estimated loss of 4.6 million fish (187 tons). The kill was traced back to
Guide Corp, an automotive parts maker in
Anderson, which had discharged of the chemical
HMP 2000 into the river. Guide Corp eventually reached a settlement whereby the company would pay a total of $14.2 million in fines, penalties, legal expenses, and river restoration. Many animals that had burrowed into the mud were protected from the chemical, and by March 2000, some fish were naturally returning to the affected area. The
Indiana Department of Natural Resources conducted a restocking program in October. The city of Anderson announced in 2002 that it would invest millions of dollars for improvements to its sewage treatment system. Ten years after the fish kill, officials with the DNR stated that the White River was in better condition than before the
environmental disaster. Stones along the bank of the river are still bleached, and are a reminder of the chemical spill. ==See also==
