Trace Metal Monitoring
In January 2009, SFWMD asked the TOC to consider dropping the last of trace metal monitoring from the Settlement Agreement NSID1 and S5A
Cadmium (Cd), Copper (Cu) and Zinc (Zn)
The TOC wanted more data on metals at NSID1 approved dropping Cd and Zn from S5A suggested Cu at S5A was a potential concern

Conclusions
There is little evidence to suggest a history of issues with trace metals at either S5A or NSID1/S38B.

Request
Eliminate the monitoring of Cd, Cu, and Zn at NSID1
Eliminate monitoring of Cu at S5A
