Our transcription: The monitoring wells provide a picture, not only of when and where contamination is occurring, but also of the geological structure of the groundwater basin.
As a well is drilled, samples of the rock are collected and analyzed.
From these data the substructure is mapped and computer models created to predict how groundwater flows through the basin.
This information is extremely important because it helps water district personnel plan how to effectively contain groundwater pollutants.
We don't wait for a regulatory agencies, such as the State or the EPA, to come to us and tell us we've got a problem.
It's too late then, so we're looking at managing our own groundwater basin as though we had to drink the water, and we do.
