Water Quality Testing - Q&A
If you are on a private shallow well and have a household member considered a high public health risk, it is a good idea to test your water for nitrate. It is a colorless, odorless, and tasteless chemical that is only detectable by chemical testing. It is also a good idea to test for coliform.
Contact a certified testing laboratory for more information. The testing laboratory will provide you with the water bottle and instructions to properly test your water.
After obtaining a water sample as directed by the certified lab, you will return the sample to the lab for analysis.
