Title: Silloth sediment survey : April, July 1990
Author: National Rivers Authority North West Region
Document Type: Monograph
Yates Circuit Foil, Silloth, discharges trade effluent to the Great Gutter, a small ditch running from the disused airfield at Silloth, through Skinburness, and out to Grune point (see figure 1). This discharge measures approximately 1.2 Ml/d and arises from the manufacture of printed cicuit boards. It contains residual amounts of toxic metals, most notably copper, and has a high sulphate concentration. Table 1 shows the mean concentrations found in samples from the effluent during the years 1989 and 1990. The consent to discharge is listed in Appendix A. Two surveys were carried out with the following aims: to assess the impact that the disharge was having in the vicinity of Great Gutter; and to evaluate background levels and any contamination around Silloth upon which an additional input to Silloth Sewer would have an impact.
