Special Session - Applying the Biological Condition Gradient for Protecting Our Waters - Regional and State Experiences I
We are now at the point where several of our state and regional programs have applied the BCG (Davies and Jackson 2006; http://www.epa.gov/bioindicators/html/bcg.html) to evaluate reference conditions and set water quality goals. There are pros and cons to these approaches, but the BCG will likely be a major mechanism for how aquatic life designated uses in water quality standards will be interpreted. We would like to use this opportunity to share several lessons learned from programs in Maine, Ohio, Florida, Pennsylvania, New Jersey. EPA Regions 1, 2 and 3, among others.
