Possible Sources of Groundwater Contamination (Failure of Septic Systems,…
Possible Sources of
Groundwater Contamination
Improper Disposal of Hazardous Waste
Non-point contamination that associated with rainfall
Pesticide, Herbicide and Fertilizer Uses
During raining, those chemicals would seep into the ground and eventually into underground water.
Mining Activities
Oxidation of minerals can lead to acidic leachate water, particularly in heavy metal and coal mining.
Landfills
If the protective bottom layer is cracked, the contaminants e.g. car battery acid, paint, and household cleaners could pollute the groundwater.
Failure of Septic Systems, Sewers or other Pipelines
The water treatment system does not work properly.
Leaking of fuel and chemical tank
Surface Water and Atmospheric Contaminants
Via hydrological cycle
Underground pipes
For transferring chemicals such as oils
Burst and releasing the transferred chemicals into the soil.
Road salt
Used to clear snow
Cause corrosion to infrastructure and making water ingested become salty. Toxic to fish
Poultry industries
Disposal of litter poorly managed.
