Bacteriological Water Testing

for the testing of drinking water samples from private and public wells for bacterial contamination.
The lab tests water from Missouri Department of Natural Resources regulated sources
such as: Jefferson County cities and water districts, mobile home parks,
subdivisions and also from similar sources
from outside of the county.
If you have a private well, it should be tested for bacterial contamination periodically to ensure the
water you drink is safe.

Drinking water samples must be collected in a sterile container provided by the health department lab.
Results are usually available in 24 - 48 hours.
