Spring 2012 Well Water Testing - Everything you need to know

Source: MorgueFileDo I need to get my well water tested?

Residents who are on a well should test their water regular to ensure their water supply is safe to drink. It is recommended that testing for bacteria is completed three times a year and after major plumbing work. Testing for nitrates is also recommended. In agricultural areas, residents may also wish to test for pesticides, herbicides, gasoline and solvents.

The bacterial stability of water cannot always be determined from a single sample. To establish drinking water quality, initially submit three samples at least one week apart. If the well shows acceptable coliform/E.coli counts, then sample three times a year.

Please do not send several samples at the same time.

Where can I drop of the samples to be tested?

  • Let the cold water run for three minutes before sampling
  • Fill the bottle to "fill line" directly from the tap without changing the flow of water
  • Replace cap tightly
  • Samples must be refrigerated after collection
  • During transportation, put bottle in a cooler if possible
  • Write down the bar code on the pink card and retain it for future reference
  • Keep the pink card - you will need the number to obtain your results
