Much interest is directed at the chemical structure of hydraulic fracturing (HF) additives in
unconventional gas exploitation. To bridge the gap between existing alphabetical …

Toxic organic contaminants may enter the subsurface as slightly soluble and volatile
nonaqueous phase liquids (NAPLs) or as dissolved solutes resulting in contaminant plumes …

The transfer of pesticides from agricultural soils to food and drinking water is a major health
issue. There are actually few robust methods to identify, characterize and quantify the …

Biodegradation and biotransformation of contaminants in groundwater commonly occurs
naturally. However, natural biodegradation rates can be slow leading to elongated …

NSO heterocycles (HET) are typical constituents of coal tars. However, HET are not yet
routinely monitored, although HET are relatively toxic coal tar constituents. The main …

Anaerobic biodegradation of organic amendments and contaminants in aquifers can trigger
secondary water quality impacts that impair groundwater resources. Reactive transport …

Water table fluctuations play a significant role in the redistribution of chemical species,
microorganisms and organic pollutants in aquifers by creating favorable zones for reactive …

Dense non-aqueous phase liquids, ie, DNAPLs and the evolving contaminant plumes in
aquifers provide significant potential to pose hazards affecting both environment and human …

The hydrochemical composition of most groundwater systems, whether pristine or affected
by anthropogenic activities, evolves as a result of complex interactions between flow, solute …

Over more than a century of intense industrial production and associated accidental release,
petroleum products (eg, gasoline, diesel, fuel oil) have contaminated a significant portion of …
