Water well records contain details of the location, construction, and groundwater level of wells drilled on Prince Edward Island.

Available as an ESRI ArcGIS Shapefile, and as a MapInfo MIF/MID file. This dataset was created in 2010.

Data collected from the Mussel Monitoring Program. Information includes date collected, year, month, water temperature, mussel larvae concentration, mussel larvae minimum size, mussel larvae maximum size, mussel larvae pre set size (%), mussel larvae set size (%), Pseudo nitzschia cells), tunicate larvae - Ciona, tunicate larvae - Styela, Tunicate Larvae – Botryllus, Tunicate Larvae – Botrylloides.

Available as an ESRI ArcGIS Shapefile, and as a MapInfo MIF/MID file. This dataset was created in 1993.

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.

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.

This data set provides results for surface water samples (streams, ponds and lakes, estuaries and bays) in Prince Edward Island.

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.

2. USEPA Aquatic Life Benchmark (lowest value on table was chosen).

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.

This data set provides pesticide sample analyses results for stream sediment samples for the province’s Pesticide Monitoring Program. The sampling includes sampling a total of nine rivers across PEI, with three of the rivers being sampled each year.

Sediment samples are collected once in July, twice in August (once during a normal/dry weather and once during wet weather), and once in September. The two samples in July and September are collected during dry weather.

Sediment sampling involves Department staff collecting sediment from the stream bed of the site, using a small shovel. Samples are then sent to a laboratory for analysis.

These samples are collected in the same rivers as the Stream Water and the Finfish/Shellfish Pesticide datasets.

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.
