Will ONWASA sample my water for contaminates?
ONWASA routinely performs 100 bacteriological samples throughout the distribution system. Although your home may not be personally tested the area you live in is represented in the sampling. The amount of chlorine is tested daily and once again your area is represented in these daily samples.
Certain tests such as lead and copper can only be sampled from homes meeting a certain criteria as there are no elevated levels of lead and copper in your source water.
All other sampling performed on your water is from the source and if no contaminants are found in the source the chances of them being found in our distribution system and therefore your home a very minimal.

If you are concerned about a particular regulated contaminant being in your home, there are independent laboratories that will analyze your water and ONWASA will be happy to provide you with those contact numbers.
