Marine monitoring at Cape Lazo, B.C. marine sewage outfall : March 1985 update and trend analysis / by Alan G. Colodey.: En40-240-1/86-20E-PDF
"Sediments and water were sampled in the vicinity of the (Comox) Cape Lazo, B.C. submarine sewage outfall on 11 March 85. A reference site 5 nautical miles away was also sampled. The water column at the outfall and the reference site was unstratified. Temperature ranged from 7.8 - 7.9°C, while salinity was uniformly 29.7 ppt. Dissolved oxygen ranged from 7.0 to 8.9 mg/L (74 - 93 % saturation). Nutrients (NH3, NO2, NO3, o-PO4, t-PO4) were not elevated at the outfall site, when compared to baseline and reference site data. Sediment nickel, lead, and hydrocarbons were all below detection limits. Sediment fecal coliforms were at or below the limit of detection (200 mpn/100 g sediment). The increase in sediment volatile residue noted in the summer of 1984, was apparently due to seasonal fluctuations. Levels detected in winter 1985 are comparable to the winter 1979 concentrations. In summary, no significant impact of the outfall on water or sediment quality was detected after about one year of sewage discharge"--Abstract, page i.
