Abstract:
The River Camel at R25B019 failed the EC Dangerous Substance Standards for total Zinc and dissolved Copper in 1993. Total Zinc concentrations increased by 4.0 microg/l between WSTW1517FE and R25B019, causing exceedence of the 8.0 microg/1 standard at R25B019. The St. Lawrence Stream was estimated to have contributed to 50% of this increase (calculated from theoretical flows). Dissolved Copper concentrations increased by 0.4 microg/1 between WSTW1517FE and R25B019, causing exceedence of the 1.0 microg/l standard at R25B019. The St. Lawrence Stream being estimated to have contributed to 100% of this increase (again calculated from theoretical flows). The objective of this report was to identify all significant sources of Zinc and Copper contamination in the St. Lawrence Stream sub-catchment, and the River Camel downstream of WSTW 1517 A; with a view to determining the cause of the failure at R25B0019, the downstream site for Bodmin (Nanstallon) STW discharge.
