| 520 | 3 |a"The Environmental Protection Service conducted a monitoring program in May 1983 to determine whether continued modifications to the collection and treatment works at Westmin Resources had resulted in improvements in Myra Creek water quality. Conductivity, residues, turbidity, sulphates, pH and total and dissolved metals were recorded. Mean copper, zinc and sulphate loadings were calculated. The Lynx pond discharge and any acid mine drainage that escaped collection and treatment appeared to be primarily responsible for the elevated copper and zinc levels in Myra Creek. The Myra ponds discharge mainly contributed to increased residue, sulphate and hardness concentrations. Metal and sulphate levels in Myra Creek were less in May 1983 than in December 1982"--Abstract, page i. |
