A laboratory study of surfactant flushing of DNAPL in the presence of macroemulsion
Article Abstract:
Laboratory sandpacks containing a dense nonaqueous phase liquid tetrachloroethylene (PCE) are treated with the biodegradable surfactant Glucopon-425N to measure the effect of pore size, flow rate, and surfactant concentration on the remediation of polluted sand. Graphs show a correlation between the use of the surfactant solution and a normalization of the PCE solution due to a smoothing of porosity in the sand.

Major ion and electrical potential distribution in soil under electrokinetic remediation
Article Abstract:
The electrical potential distribution of a soil during electrokinetic remediation treatment and major ion concentrations in the pore water were modified to discover the impact of pore water chemistry on the removal rate of contaminants. Electrokinetic remediation, which is a technology that was developed for contaminant removal from soils and sediments, has advantages over other techniques because it can be practiced both in principal and in situ.

An improved thermal oxidation method for the quantification of soot/graphitic black carbon in sediments and soils
Article Abstract:
Soot/graphitic black carbon and char/charcoal black carbon are measured in soils and sediments from Mexico using thermal oxidation. Concentrations of black carbon are graphed in comparison to total organic carbon.
