Monitoring of the Desjardine Drain's water and sediments for bacterial and chemical contaminants continued for the 1988 - 1989 fiscal year. Minor remedial work performed in 1988, involved repairs to a septic system and a barn bank which had been installed by the beaches program in 1988 and 1987 respectively. Water quality continues to follow seasonal trends and appears to be improving. While there were significant improvements in water quality in the summer of 1987 compared to summer 1986, little change was noted between the spring of 1987 and spring of 1988. E. coli concentrations continued to decrease at the downstream sampling station in 1988, possibly due to continued septic system repair. Further statistical analysis is required. There were no beach closures at Grand Bend due to bacterial contamination during the 1988 swimming season. Special research conducted in cooperation with the Ministry of the Environment -Southwestern Region continues including tracer experiments to determine the downstream movement of bacteria and the impact of sunlight on bacterial survival as well as pyocin work to pinpoint specific sources of bacteria.
