Environmental management is becoming increasingly dependent on quantitative analysis of environmental and health risks associated with exposure to chemical contaminants. Exposure to chemical pollutants can occur via primary pathways (e.g., inhalation of polluted air or drinking contaminated water) and/or secondary pathways (e.g., ingestion of contaminated food) and therefore requires information on chemical distribution in the environment.

The development of new chemicals and synthetic drugs require understanding of the role of various chemical functional groups on the activity of various drugs and the impact of such functional groups on the physicochemical properties of such chemicals and drugs (e.g., aqueous solubility and lipid phase partitioning).

Deterministic modeling of complex chemical and separation processes is often infeasible when such processes involve a series of complex steps and are affected by numerous variables. Recent, advances in neural network system design have made it possible to map complex process behavior, given sufficient operational data, and to be able to make generalizations regarding the process and even assess potential process upsets.

Drinking water supplies are dwindling around the globe due to aggressive water consumption practices in both urban and agricultural areas. As a result, the salinity of groundwater and surface water supplies has been on the rise in many regions and even in California, salinity (i.e., mineral salt concentration) has been on the rise.

Membrane fouling due to mineral scale formation is a problem often encountered in the reverse osmosis membrane desalination of surface water, groundwater and agricultural drainage (AD) water. Concentration polarization can result in the concentration of mineral salt ions exceeding the solubility limit. As a consequence, mineral salt precipitation may occur in solution, and also crystallize directly on membrane surfaces.
