Environment and Food
Dataset
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.
1. The Canadian Long term freshwater Water Quality Guideline for the Protection of Aquatic Life
Website link is here: http://st-ts.ccme.ca/
2. USEPA Aquatic Life Benchmark (lowest value on table was chosen).
Website link is here: http://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/aquatic-life-benchmarks-pesticide-registration#use
3. Health Canada Guidance Value
NOTE: the guideline/benchmark values have been converted from the published units to ng/ml by the author in order to compare the values to the detected results.
These samples are collected in the same rivers as the Finfish/Shellfish and the Stream Sediment Pesticide datasets.

Environment and Food
Dataset
Groundwater level search results include data from 14 groundwater level observation wells across PEI; mapped locations of observation wells; graphs; and downloadable raw data. The groundwater level data provides long-term trend information, both historical and real-time, on groundwater levels.

Environment and Food
Dataset
This Data set provides detailed information about the quality of drinking water. The application provides a summary of the on-going testing of drinking water done by the Prince Edward Island Analytical Laboratories.
The summary results will show values for the following parameters: alkalinity, cadmium, calcium, chloride, chromium, iron, magnesium, manganese, nickel, nitrate, pH, phosphorus, potassium, sodium, and sulfate.

Environment and Food
Dataset
The province of PEI has been monitoring dissolved oxygen in some Island estuaries since 2015. This dataset contains data collected from 2015 to 2021. Monitoring results from later years can also be found on the Prince Edward Island open data portal.
This dataset includes raw data from 20 Island estuaries from across PEI; mapped locations of monitoring sites; and downloadable raw data. The data includes dissolved oxygen concentration, dissolved oxygen saturation, water temperature and instrument depth. Data is usually collected between May and October of each year. 18 estuaries are monitored on a 3 year rotating cycle with at least 6 of these 18 monitored in any given year. Another 2 estuaries are monitored every year. 2 locations are monitored in each estuary; the Upper Estuary location represents the upper 10% boundary of the estuary’s surface area, is closest to the freshwater inputs and should display signs of eutrophication if they are present; the Mid Estuary location represents the mid-point or 50% boundary of the surface area of the estuary. The Mid Estuary site may have two loggers, one placed about 0.5 m the bottom substrate and one placed about 0.5 m from the surface of the water. Data may be used to determine hourly fluctuations in oxygen, the degree of eutrophication, and the presence and duration of anoxia and hypoxia. Temperature and instrument depth (not the same as water depth at the site) data are also collected and available for use.
