Investigating the toxicity of Dense Non-aqueous Phase Liquids (DNAPL) in contaminated groundwater

M.Tech. Biomedical Technology / Previous studies have reported on the potential health risks associated with direct contact with chemicals (such as DNAPLs) via inhalation or drinking of contaminated groundwater. Dense Non-Aqueous Phase Liquids (DNAPLs) enter into groundwater through incorrect storage or disposal and pose risk to human health. Industrialization contributes considerably to contamination of ground water with waste disposal practices leading to the deposition of hazardous waste at geologically/hydro-geologically unsuitable locations. Many hazardous chemicals found their way into groundwater by this mean and might cause problems if ingested in drinking water. Most of these compounds undergo only limited degradation in the subsurface, and persist for long periods of time while slowly releasing soluble organic constituents that present hazardous health effects (both toxic and non-toxic) to humans.
