Identify Impaired Waters
Previous sediment samples from Bruce Pond (03/13/08) showed that only the top 2 feet of sediment was influenced by past municipal sewage inputs. Additional core samples were collected on April 16th, 2009 to better define the distribution of heavy metal contaminants within the top 2 feet of sediment. Cores were collected from 3 sites (table 1) and partitioned into 0.5 feet segments. Segments from the 3 sites were composited prior to analysis.

Sediment Remediation Phase 6 - Post-remediation Monitoring
Total sediment depth will be determined by probing at 5 sites during the winter of 2007-8. Sediment cores will be collected from these sites in the pond and divided into 4 layers. A composite sample for each of the 4 layers will be analyzed.
