water well monitor training

A well is more than a hole in the ground that is used to produce water or for monitoring water quality. Each well needs to be designed and constructed to meet the unique aspects of the hydrogeologic environment and the purpose for which it is intended. The purposes range from obtaining thousands of gallons per minute from a heterogeneous sand ...

There are a lot more useful and appropriate purging and sampling device options available than the bailer! Learn what types of sampling devices are appropriate for a variety of analytical parameters, and which devices should never be used for some parameters. This series of 2 modules provides a detailed discussion of a wide range of devices ...

The well is installed, the surface completion is finished but the well is still not ready to sample.  Development is a critical step following construction of monitoring wells that is often short-changed or, sometimes, not implemented at all when new wells are installed at a site.  This can result in a detrimental impact on the ability ...

Water quality depends upon well-defined water quality standards and criteria, consistent and well-constructed monitoring and evaluation programs, and a legal framework that produces effective incentives to control public and private activities that may result in water pollution and the degradation of aquatic habitat.
