Table of Contents Introduction Background TMDL Development TMDL Implementation Monitoring Introduction Pennsylvania has conducted monitoring of fish tissue contaminants since 1976. Early efforts were comprised of special studies in major water bodies as well as smaller waters with suspected sources of contaminants. Because Pennsylvania wanted the fish tissue monitoring program to focus on protection of public health, we began sampling both the edible portion and whole body at one-half of the stations. In 1987, Pennsylvania began sampling the edible portion almost exclusively.
Fishing is a wholesome, relaxing pastime, and fish are nutritious and good to eat.
Some fish, however, may accumulate contaminants to levels that may be harmful to those who eat them over a long period of time. In addition, the annual list and any individual advisories needed between lists are issued using press releases. They were listed because long-term, unrestricted consumption of these fish could potentially lead to human health problems. This document addresses contamination of fish tissue in the Monongahela River, Greene County, by PCB and chlordane. The advisory was reissued in 1991 and 1992, and remains in place.
