2.05.6 Mitigation of the Impacts of Mining Operations
QUALITY COAL PILE TCLP LEACHATE DATA — RW -1 COMPARISON:
* Dissolved
A TCLP with neutral leachate was also run on the clean coal sample to
obtain information that could not be obtained with the standard TCLP test
that uses acidic leachate.
A geochemical analysis was also performed on the clean coal to
determine parameters that cannot be determined by a TCLP procedure.
The complete data are presented in Volume I, Tab 6.
QUALITY COAL PILE LEACHATE DATA — COMPARISON TO RW -1:
EC (umhos /cm)
TCLP Geochemical
47.1 409
EC is electrical conductivity. ABP is acid base potential.
6575 2344
The pH is in the range of expected values for this type of material although
the TCLP derived pH is a little low. The conductivity values are low. The
acid base potential is not typical of the coal in this region.
Ground water in the vicinity of the loadout area is characterized by alluvial
well RW -1. All four quarters of 2010 were analyzed and the average pH
