Pesticide Concentrations in Ontario Stream Water Monitoring Sites

19 active monitoring sites in southern Ontario track pesticide levels in stream water. The dataset includes location data for 21 stations and pesticide concentration measurements from samples collected by the Ministry of the Environment, Conservation and Parks and the Ontario Ministry of Agriculture, Food and Agribusiness.

Use Cases

• Analyze pesticide concentration levels across the 19 active monitoring sites to identify spatial pollution trends.
• Model the relationship between land use (predominantly agricultural) and pesticide concentration levels in tributaries.
• Assess temporal trends in pesticide pollution using concentration data from the monitoring station network.

Strengths

• Data originates from a joint monitoring program by two provincial government ministries.
• Covers 19 active monitoring sites within watersheds, providing spatial coverage.
• Includes location data for 21 total stations, offering historical context.

Limitations

• Sample size and temporal coverage are unspecified, limiting trend analysis.
• Geographic scope is limited to selected tributaries in southern Ontario.
• Data granularity (e.g., sampling frequency, specific pesticides measured) is not detailed.
