Threats to groundwater supply

  • Threats to groundwater supply
    • Over- pumping
      • Too much extracted can leave not enough left to provide a reliable supply
    • Pollution
      • Nitrates, pesticides and microbes from agricultural run-off and sewage
      • Hydrocarbons and solvents from petrol stations/ factories
      • Toxic fluids from landfill sites
      • Acid mine drainage water containing toxic metals such as lead from abandoned mines
      • Once polluted it can be difficut to clean with unconfined aquifers more at risk than confined
