Antimony occurs naturally in small amounts in several minerals in the earth’s crust, is used in various manufacturing processes, and is present in plumbing solder. It can enter drinking water as a result of the weathering of rocks and soils, from...

Arsenic is a naturally occurring element that is widely distributed throughout the Earth’s rocks and soils. Arsenic can be dissolved from arsenic bearing minerals in the soil or rock and be present in groundwater. On a more local basis, arsenic can...

In a situation in which the drinking water in a residence is found to contain unacceptably high levels of bacteria, the occupant is advised to follow the recommendations listed below: Safety Recommendations 1. Drinking Water and Food Preparation...

La contamination bactérienne est le problème de qualité de l’eau le plus courant auquel sont confrontés les propriétaires de puits privés. Il existe de nombreux types de bactéries. Les tests en laboratoire ne détectent que deux types d’organismes «...

Barium is a naturally occurring element that is found in small quantities in a variety of minerals. Varying amounts of barium can be dissolved as water passes through rocks and soils and be present in groundwater. Barium may also be present in the...

Chloride is a naturally occurring element that is common in most natural waters and is most often found as a component of salt (sodium chloride) or in some cases in combination with potassium or calcium. The presence of chloride in groundwater can...

Il est suggéré de désinfecter chimiquement ou de chlorer l’eau provenant d’un puits contaminé par des bactéries. Les puits, nouveaux ou réparés, et leur plomberie doivent être désinfectés avant d’être mis en service. La désinfection annuelle de...

La dureté est généralement définie comme la capacité de l’eau à neutraliser le savon, ou l’incapacité de l’eau à former une mousse de savon. L’eau dure est causée par des concentrations élevées de calcium et de magnésium dans l’eau, et peut entraîner...

L’Île-du-Prince-Édouard suit les Recommandations pour la qualité de l’eau potable au Canada pour évaluer la salubrité de l’eau potable et son utilisation à des fins domestiques. Les valeurs les plus importantes sont les « concentrations maximales...

Bacterial contamination is the most common water quality problem faced by private well owners. This information sheet will lead you through the step-by-step procedure to deal with cases of bacterial contamination of private wells. Step 1: Results of...

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...

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 occurs naturally in PEI rocks and soils. Usually it is not easily dissolved from these sources and its concentration in well water is low. In some cases, particularly in swampy areas where oxygen levels in groundwater are low, manganese is...

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...

What are PFAS? Per- and polyfluoroalkyl substances (PFAS) are a class of over 4,700 synthetic chemicals known for their stability and persistence in the environment, earning them the nickname "forever substances." First used in the 1940s, PFAS are...

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...

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...
