Well Water Quality
Currently the CCNRD does not have the capability to sample water for e. coli, but the Department of Environmental Quality (DEQ) has a great site with information about what tests you should perform on your well annually, as well as a list of labratories. Additionally, you will find a tool that you can input your well test results into for more information about your results.
See the list of Laboratories if you are looking for a place to have your well water tested.
