But lets lesson standards since Bush doesn't believe in scientific study.
WASHINGTON - One of every three lakes in the United States, and nearly one-quarter of the nation's rivers contain enough pollution that people should limit or avoid eating fish caught there.
Every state but Alaska and Wyoming issued fish advisories covering some and occasionally all of their lakes or rivers in 2003, according to a national databased maintained by the Environmental Protection Agency (news - web sites) and updated every year.
Though the number of advisories rose to 3,094, up from 2,814 in 2002, according to figures released Tuesday, EPA Administrator Mike Leavitt said the increase was due to more monitoring, not more pollution.
Nearly all the advisories involve contaminants such as mercury, dioxins, PCBs, pesticides and heavy metals, including arsenic, copper and lead. Currently they cover 35 percent of the nation's lake acreage and 24 percent of river miles.
