The 45 pages that link to Groundwater contamination, each with the reason it gives.

• SolubilityRelated: A contaminant's solubility affects how readily it enters and moves through groundwater.

• KarstRelated: Rapid conduit flow can carry pollutants through karst with limited natural filtration.

• GroundwaterRelated: Contaminants can persist and spread through aquifers, compromising water supplies.

• AquiferRelated: Contaminants can move through aquifers and compromise wells and springs.

• Water qualityBroader topic: Contaminants can persist underground and impair wells that supply drinking water.

• Water pollutionBroader topic: Pollutants can seep through soil and persist in aquifers used for drinking water.

• Water tableRelated: Contaminants can move downward through soil and reach the water table.

• Groundwater rechargeRelated: Recharge can carry contaminants from the surface into aquifers.

• LandfillRelated: Leachate migration can contaminate aquifers if containment or monitoring fails.

• Hazardous wasteRelated: Hazardous waste can release pollutants that migrate into drinking-water sources.

• Concentration gradientRelated: Dissolved contaminants disperse and diffuse along spatial concentration differences.

• Groundwater flowRelated: Flow transports contaminants away from their sources through aquifers.

• HerbicideRelated: Some herbicides can leach through soil and reach groundwater.

• LeachingRelated: Leached chemicals can pass through soil and reach underlying aquifers.

• Underground RiverRelated: Fast flow through underground conduits can spread pollutants with little filtration.

• Pesticide residueRelated: Residues that migrate through soil can contaminate groundwater used for drinking or irrigation.

• HydrogeologyRelated: Hydrogeological flow paths determine how contaminants spread and where they may reach.

• BariumRelated: Mining and industrial wastes can release barium compounds into water supplies.

• Environmental fateBroader topic: Fate processes determine whether contaminants reach and persist in aquifers.

• Chemical wasteRelated: Leaking chemical waste can introduce contaminants into groundwater.

• Dry cleaningRelated: Leaks and spills of chlorinated cleaning solvent can persist in soil and reach groundwater.

• Septic tankRelated: Poorly treated or leaking septic effluent can carry contaminants into nearby groundwater.

• Artesian wellRelated: A poorly sealed artesian well can connect contaminated surface water with a confined aquifer.

• Pit latrineRelated: Leaching from a pit can contaminate nearby groundwater, depending on soil, water table, and siting.

• Water chemistryRelated: Water reactions govern how contaminants persist and move through aquifers.

• Confined aquiferRelated: Confining layers may reduce contaminant entry, but leakage and wells can provide pathways.

• Pump and treatNarrower topic: Pump and treat is applied to contamination dissolved in aquifers.

• Water wellRelated: Poor construction or nearby pollution can make well water unsafe.

• Agricultural pollutionRelated: Nitrate and pesticide residues can leach from agricultural land into aquifers.

• EthylbenzeneRelated: Leaks and spills can carry ethylbenzene into soil and groundwater.

• Shale gasRelated: Potential pathways from wells and surface operations have driven disputes over shale development.

• Methyl tert-butyl etherRelated: Leaking fuel tanks can release MTBE, which travels readily through groundwater.

• ChlorobenzeneRelated: Chlorobenzene can reach groundwater through spills, leaks, and contaminated industrial sites.

• 1,2-DichloroethaneRelated: Leaked 1,2-dichloroethane can reach groundwater and persist there.

• Perfluorooctanoic acidRelated: Releases from industrial sites and firefighting areas have contaminated groundwater with PFOA.

• Guarani AquiferRelated: Pollution in exposed recharge areas can threaten water stored beneath extensive covered zones.

• NitrobenzeneRelated: Leaks or industrial releases can introduce nitrobenzene into groundwater.

• Unsymmetrical dimethylhydrazineRelated: Spills and discarded rocket stages can release UDMH into soil and groundwater.

• 1,1-DichloroethyleneRelated: Industrial releases can make vinylidene chloride a contaminant of concern at affected sites.

• 1,4-DioxaneNarrower topic: Leaking industrial wastes and disposal sites have introduced 1,4-dioxane into aquifers.

• AgrochemicalRelated: Some mobile agrochemicals can leach below fields and reach aquifers.

• Chemical hydrologyBroader topic: Chemical transport and reactions determine contaminant persistence and spread underground.

• FrackingRelated: Concerns focus on spills, faulty well barriers, and pathways connecting operations to aquifers.

• Solutional caveRelated: Rapid flow through cave conduits can carry contaminants with little natural filtration.

• Underground lakeRelated: Pollution can travel through cave conduits into lakes with little natural filtration.
