The objective of the 1992 Halton Region Conservation Authority (HRCA) CURB water quality monitoring program was to continue the program to identify the sources and types of bacterial pollutants that affect the Kelso Reservoir swimming area and to provide base line data to help access the impact of remedial projects. The program continued to make use of an extensive water sampling network already established. The water quality analyses consisted of i) bacterial analyses ii) nutrient, chemical and physical analyses.
