Prepacked Screen Monitoring Well ASTM Standards


Regulatory Compliance

Many state regulatory agencies have approved the use of prepacked screen wells installed by direct push methods, and more states are joining this movement on an almost daily basis.  Likewise, many federal agencies have specified the installation of direct push prepacked screen wells for their permanent groundwater monitoring needs.

The U.S. Environmental Protection Agency has recommended the use of prepacked screens in their guidance document, "Expedited Site Assessment Tools for Underground Storage Tank Site, " (EPA, 1997).  Geoprobe® brand prepacks meet the requirements of ASTM Standards for the installation of prepacked screen monitoring wells (ASTM D6725-01).

Current standards are available from ASTM (610-832-9500 or www.astm.org).
