This data set provides pesticide sample analyses results for drinking water samples for the province’s Pesticide Monitoring Program.
Over 100 wells are monitored annually, with samples being collected in drinking water wells of private homes, schools, municipalities, and seniors’ housing facilities. Sampling of the wells is conducted each January/February by Departmental staff. The samples are sent to a laboratory in New Brunswick for analysis. The purpose of the program is to monitor the environment for the presence of pesticide residues.
To create a long-term record of pesticide detections in drinking water, the same sites are sampled each year. Individual site locations are not listed to respect the privacy of the individuals involved, as this is a voluntary program for all participants. Public buildings (e.g., schools and seniors’ housing) are identified. The non-public building sites are listed as letter/number combinations (e.g. A1, AA, FFF, etc.) The designations remain consistent for each site from year to year.
The dataset also includes chemistry analyses for the sites. Additional water samples were collected at the same time as the pesticide sampling, which were then analyzed at the PEI Analytical Laboratory for various chemistry parameters. Users should note that the parameters analysed and the lab detection limits for these chemistry samples/results may vary from year to year. Chemistry sampling ceased after the 2013 sampling year.
Transportation Statistics, Prince Edward Island. Data represents an estimation of the annual two–way traffic volume for the Confederation Bridge with the annual change as well as summer and winter traffic.
Stream level data is available for a number of streams across the province. New Stream level data can be collected from June through September. Those who hold a Water Withdrawal for Irrigation Purposes Permit can use this tool to confirm the water level in Island streams, and to determine whether they may legally draw water for irrigation purposes.
This data set provides pesticide sample analyses results for stream water samples for the province’s Pesticide Monitoring Program.
The sampling includes a total of 9 rivers across PEI, with at least 3 of the rivers being sampled each year.
Stream water samples are collected at least once per year during wet weather sampling conditions.
Department staff collects the samples, which are then sent to a laboratory for analysis.
Results with a " < " represent values below the lab's reporting or quantification limit.
Such results do not confirm the presence nor the absence of a pesticide compound below that level.
Water Quality Guideline or Benchmark Values:
When available, Health Canada Guidance Values were used,
otherwise CCME Canadian Water Quality Guidelines for the Protection of Aquatic Life were used, and otherwise USEPA Aquatic Life Benchmark values were.
