Summary:
The American Society for Testing and Materials (ASTM) has an active program on developing
standards for use of direct push technology for environmental sites characterization. Numerous
ASTM subcommittees are working on standards for environmental site characterization. ASTM
committee D-l 8 on Soil and Rock developed subcommittee D-18.21 to develop standards on
ground water and vadose zone investigations. Direct push technology is focused in
subcommittee section D-l 8.21 .O 1 on direct push technology. Standard guides have been
published on direct push soil and water sampling. Standards on use of the electronic cone
penetrometer and the use of laser induced fluorescence have been completed. A general guide on
different induced fluorescence techniques are under development. Standards are needed for
resistivity/conductivity penetrometers. There are new penetrometer sensors being developed
which will eventually require standardization. The approach has been to generate general
information guides and then to develop more specific operations techniques for specific sampling
systems. Contrary to claims of ASFE and NGWA our guides do not restrict the use of
engineering judgement or development of new technologies. ASTM standards will evolve to
include new technologies as they are developed. However, monetary support from government is
now gone, the process is time consuming, and many participants find it hard to generate the
needed standards. It is doubtful the section will generate specific operations guides for
individual equipments.
