The objectives of this study were:
1. to determine the areal extent of discharged materials within each of the rivers using the aluminum:silicon ratio as an indicator;
2. to evaluate the benthic invertebrate communities within each of the rivers;
3. to determine whether there are differences in the productivity of the benthic algal and planktonic communities which can be attributed to the discharge of alum sludge in each river;
4. to evaluate the condition of the marsh communities in each river near the filtration plant;
5. to review historical biological data for the Poquoson and Warwick Rivers and to relate …
