Iron is a naturally occurring element that is common in PEI rocks and soils. Iron can occur in well water for two reasons; it may be present in fine sediment particles, or it may be present in dissolved form in the water. A reddish-brown colour to the...
Lead is a naturally occurring element that is present in some minerals in rocks and soils, but the main source of lead in drinking water is generally through contact with plumbing components containing lead. The amount of lead dissolved into drinking...
Manganese is a naturally occurring element that is common in PEI rocks and soils. Under oxygen-rich conditions, manganese is relatively insoluble and its concentration in groundwater is generally quite low. In cases where oxygen levels in groundwater are...
Over 100 wells are monitored annually, including those that provide drinking water to private homes, schools, municipalities, and seniors’ housing facilities. Sampling of the wells is conducted each January/February by departmental staff. The collected...
Nitrate is a naturally occurring form of nitrogen that is commonly found throughout the environment. It is present at low levels in most groundwaters, but can be present significantly higher levels in areas with extensive use of fertilizers, storage and...
Nitrate is a form of nitrogen. It can readily dissolve in water and can travel easily through soil to the water table. As a result, nitrate is common in our groundwater, ponds, streams, and estuaries.
Human activity is responsible for over 90% of...
What is the climate of Prince Edward Island?
Prince Edward Island has a mild maritime climate, strongly influenced by the warm waters of the Gulf of St. Lawrence. Each year, the Island gets about 890 mm of rain and 290 cm of snow. The average...
Drinking water and dairy testing are considered essential services at PEI Analytical Laboratories. The laboratory continues to accept and process drinking water samples for bacteria and all dairy sample types for bacteria and components. The dairy...
Surface water from nine rivers is sampled under the Pesticide Monitoring Program. At least three of the nine rivers are sampled each year for a selected number of pesticides.
Stream water samples and sediment samples are collected once in July, twice...
Wetlands are shallow, wet areas that support aquatic plants such as sedges, bulrushes and cattails, as well as shrubs and trees. These areas provide habitat for waterfowl, fish, amphibians and hundreds of invertebrate species.
Why are wetlands important...
The Water Supply and Wastewater Treatment System Regulations will be established under the Water Act to regulate public water supplies and municipal wastewater treatment systems. As required by the Water Act, they have been submitted to the Standing...
The Water Withdrawal Regulations will be established under the Water Act to regulate the withdrawal of water from groundwater and watercourses.
The proposed regulations and plain language documents are available below:

The Well Construction Regulations will be established under the Water Act to regulate the construction standards of wells and the licensing of well drillers. As required by the Water Act, they have been submitted to the Standing Committee for...
Each year people see things in streams, ponds and estuaries that cause concern, but this does not mean that the water is polluted. Often, there is a natural cause for these conditions.
If you are concerned about water quality because of something you...
Selenium is a naturally occurring element that is widely distributed throughout the Earth’s rocks and soils and is found in trace quantities in most plant and animal tissues. Selenium can be dissolved by weathering of minerals in the soil or rock or...
Sodium is a naturally occurring element that is widely distributed throughout the Earth’s rocks and soils, most often found in combination with chloride in the form of salt (sodium chloride). The presence of sodium in groundwater can result from a number...
Do I need to have my drinking water tested?
It is generally recommended that homeowners using drinking water from their own well should get their water tested for bacteria at least once a year and should have a chemical analysis of their well water done...
Uranium is a naturally occurring element that is widely distributed throughout the Earth’s rocks and soils. Uranium can be dissolved from minerals in the soil or rock and be present in groundwater. The concentration of uranium in water is typically very...
