Chase Environmental Group (Chase) was contracted to repair
existing damage created through erosion. Site work including
clearing, grubbing, and the removal of surface debris in
preparation of the landfill surface for installation of
concrete infilled Geocells, geosynthetic liners and HDPE
liner systems. The project included detailed surveys and
excavating damaged areas prior to installing the improved
drainage channels.
The project involved identifying, testing, and transporting
to the Superfund Site, suitable clay and topsoil materials
that could be constructed into a low permeability cap with
sufficient root zone thickness to meet the construction
quality assurance and cap design documents. Chase and subcontractor
personnel used company-owned equipment to prepare the materials
in accordance with the design specification, compacting
and contouring existing and borrow material to grade specifications,
placing erosion matting (Enka 7010), and placing either
concrete or infilled geocells as final layers. The site
is currently under temporary shut-down due to hazardous
working conditions.
