Surface complexation models: An evaluation of model parameter estimation using FITEQL and oxide mineral titration data
Abstract The ability of surface complexation models (SCMs) to fit sets of titration data as a function of changes in model parameters was evaluated using FITEQL and acid-base titration data ofExpand

TCLP underestimates leaching of arsenic from solid residuals under landfill conditions.
Recent revision of the arsenic in drinking water standard will cause many utilities to implement removal technologies. Most of the affected utilities are expected to use adsorption onto solid mediaExpand

Leaching of arsenic from granular ferric hydroxide residuals under mature landfill conditions.
Most arsenic bearing solid residuals (ABSR) from water treatment will be disposed in nonhazardous landfills. The lack of an appropriate leaching test to predict arsenic mobilization from ABSR createsExpand

Fate of wastewater effluent hER-agonists and hER-antagonists during soil aquifer treatment.
Estrogen activity was measured in wastewater effluent before and after polishing via soil-aquifer treatment (SAT) using both a (hER-beta) competitive binding assay and a transcriptional activationExpand

Nitrogen Transformations during Soil–Aquifer Treatment of Wastewater Effluent—Oxygen Effects in Field Studies
Depth-dependent oxygen concentrations and aqueous-phase total ammonia and nitrate/nitrite ion concentrations were measured in the field during the infiltration of wastewater effluent. MeasurementsExpand

Effect of pH, competitive anions and NOM on the leaching of arsenic from solid residuals.
Implementation of the new arsenic MCL in 2006 will lead to the generation of an estimated 6 million pounds of arsenic-bearing solid residuals (ABSRs) every year, which will be disposed predominantlyExpand

NDMA Treatment by Sequential GAC Adsorption and Fenton-Driven Destruction
N-nitrosodimethylamine (NDMA) is a highly toxic environmental contaminant that was first detected in groundwater tainted by rocket fuel manufacturing wastes. NDMA is also a by-product of certainExpand

Fate of effluent organic matter during soil aquifer treatment: biodegradability, chlorine reactivity and genotoxicity.
Hydrophobic acid (HPO-A) and transphilic acid (TPI-A) fractions of dissolved organic matter (DOM) were isolated from a domestic secondary wastewater effluent that was polished via soil aquiferExpand

Effect of silicic acid on arsenate and arsenite retention mechanisms on 6-L ferrihydrite: A spectroscopic and batch adsorption approach.
The competitive adsorption of arsenate and arsenite with silicic acid at the ferrihydrite-water interface was investigated over a wide pH range using batch sorption experiments, attenuated totalExpand
