grade product and potable water-grade
product. For potable water, we suggest
that those in North America follow NSF
61. In Australia and the Asia Pacific
regions, the preferred test is AS/NZ 4020,
which is a more stringent potable water
test. As certain EIA products are promoted
into exposed potable water applications,
we have also specified a 90-day
chlorinated water immersion test per GRI
GM 24. This accelerated test includes
testing the surface cracking and tensile
properties retained.
Despite the lack of a complete set of

specifications, it is felt that GSI's geosynthetic
material specifications have
brought a considerable amount of order
to generic geomembrane specifications.
While some manufacturers are reluctant
to participate in such efforts, the specifying
community is certainly pleased with
the results to date as evidenced by the
widespread use of GSI's specifications.
We continue to maintain and update
the existing specifications and develop
new ones.

reinforced geomembrane options, we
offer Table 1 and Figures 1 through 7.
These materials contrast one another and
provide engineers various tools to meet
clients' containment needs that cannot
be met by nonreinforced films, barriers
or geomembranes.
Geosynthetics are a viable and rela7
tively
developed subset of engineering
materials. As such, the industry needs
generic specifications to champion the
quality of geosynthetics worldwide. In
short, the time is right for a generic EIA
geomembrane specification. If you are
interested in participating with the development
of the EIA geomembrane specification,
please reach out to us ASAP to
get involved with this effort. G
