The relationship between RMD and
ionic strength for the CCR leachates is
shown in Figure 2 along with leachates
in the Electric Power Research Institute
(EPRI) leachate database reported by
Chen et al. (2018, 2019). The CCR leachates
in this study (closed symbols in
the figure) predominantly have ionic
strengths in the upper portion of the
ionic strengths in the EPRI leachate
database and tend to have lower RMD
(more polyvalent).
Geosynthetic clay liners
Seven commercially available BPC GCLs
were evaluated in this study. All of the
BPC GCLs are manufactured by dry mixing
one or more granular proprietary
polymers (cross-linked or linear polymers)
with granular sodium bentonite.
The BPC GCLs are labeled as BP4.0,
BP5.8, BP6.3, BP8.6, BP8.9, BP9.0 and
BP9.7, with the numerical suffix representing
the polymer loading in percent
by dry mass as measured based on loss of
ignition (LOI) of the BPC and NaB using
the procedure in Scalia et al. (2014).
Hydraulic conductivity of GCL
Hydraulic conductivity tests were conducted
on 6-inch (150-mm) diameter
GCL specimens using flexible-wall permeameters
in accordance with ASTM
D6766. The falling headwater-constant
tailwater method was used (Figure 3).
GCL specimens were trimmed from the
