This paper describes the results of an above-ground pilot test of
zerovalent zinc (ZVZ) for degradation of 1,2,3-trichloropropane (TCP).
The work was a collaboration with Geosyntec, funded by the Navy. I'm
pretty sure that it is the first on-site test of granular ZVZ for
groundwater treatment. Some preliminary work that we did in
preparation for this study is described in Battelle Chlorcon
Conference proceedings papers, which are available from

2012. Evaluation of zerovalent zinc for treatment of 1,2,3-
trichloropropane contaminated groundwater: Laboratory and field
assessment. Ground Wat. Monitor. Remed. 32(4): 42-52.
The efficacy and feasibility of using zerovalent zinc (ZVZ) to treat
1,2,3-trichloropropane (TCP)-contaminated groundwater was assessed in
laboratory and field experiments. In the first portion of the study,
the reactivity of commercially available granular ZVZ toward TCP was
measured in bench-scale batch-reactor and column experiments. These
results were used to design columns for on-site pilot-scale treatment
of contaminated groundwater at a site in Southern California. Two of
the ZVZ materials tested were found to produce relatively high rates
of TCP degradation as well as predictable behavior when scaling from
bench-scale to field testing. In addition, there was little decrease
in the rates of TCP degradation over the duration of field testing.
Finally, no secondary impacts to water quality were identified. The
results suggest that ZVZ may be an effective and feasible material for
use in engineered treatment systems, perhaps including permeable
reactive barriers.
