We can all agree that the quality of your drinking water is very important. If you are on municipal water or are served by a water district, the water is already tested regularly. But if your water comes from a well or is hauled in and placed in a cistern then you should regularly test your water.
Testing your well water
Wyoming DEQ recommends sampling annually for a select list of constituents (bacteria and nitrate) and every 5 years for a comprehensive list of constituents. You should also test when:
- When there is an unexplained illness in the household,
- If there are changes to the taste, color or odor of the water,
- If there are spills of chemicals or fuel near your well, or
- If your neighbors find contaminants in their well
The District offers cost share on well water testing for District members. Collection dates are offered in the spring and fall annually. See below for upcoming testing dates and information. The Annual Well Maintenance test tests for bacteria and nitrates, while the Domestic plus Bacteria test offers a more comprehensive test. Tests for livestock and irrigation suitability are also offered.
Well Siting and Maintenance
Homeowners are responsible for maintaining their water well and testing the water quality. This will help prevent contamination from getting into the groundwater. This includes not only properly locating your well site, but also maintaining the integrity of the well and protecting it from contamination. The Wyoming Department of Environmental Quality recommends homeowners test their water every other year.
For information on properly maintaining your well, see the article in the Barnyards and Backyards magazine: You are responsible for the quality of your domestic well water
Do you haul water? Testing your cistern…
Whether hauling yourself or paying a hauling service, be sure to use clean water. It is also recommended that homeowners test the water from their cistern at least annually as well. And annual cleaning is also important to help remove sludge and sediment buildup. Also clean and test the water:
- When the water looks, smells, or tastes different than usual, and a test tells you it’s contaminated
- When contaminants—such as rodents or water from overland flooding—get in the cistern
- After the cistern is installed and sediment needs to be removed from the bottom of the tank
Tips on cleaning your cistern from My Health Alberta:
It is the homeowners responsibility to maintain their cistern the same as a private well, to ensure safe drinking water. The same tests for well water will also work to test the water from your cistern.
