The department's Health Protection branch has in place preventive measures to ensure the safety of drinking water supplies. These measures are meant to reduce the incidence and spread of some communicable diseases and reduce exposure to contaminants often found in drinking water supplies.
The Drinking Water Quality Guidelines in New Brunswick can be found in the information section. Please refer to the web page entitled "Understanding your Water Quality Results" for important information on how to read your water test results.
The Department of Environment maintains a database of groundwater quality data collected from domestic wells drilled since 1994. This information can be obtained from the Department of Environment website.
Importance of testing private water supplies
Water from private water supplies should be routinely tested twice a year for Total Coliform and E.coli when the water supply is most at risk- after the spring thaw and during the autumn rainy season. Testing should be done even if there are water treatment devices installed on the water system.
Water should be re-tested after any event that could have affected the microbial safety of the water supply, for example a sewage back-flow in the area of the well, or a flood. The water should also be re-tested if there is a change in the appearance, taste or odour of the water.
