Groundwater contamination occurs when man-made products such as gasoline, oil, road salts and chemicals get into the groundwater and cause it to become unsafe and unfit for human use. ... Road salt, toxic substances from mining sites, and used motor oil also may seep into groundwater.

How do humans pollute the water?
People are polluting our water. Businesses and cities dump chemicals and waste products into our rivers, lakes and oceans. People throw trash–furniture, garbage, old tires, cars, old fencing, anything they can think of–into the water. ... The acid rain caused by pollution poisons water on the surface of the earth.
What are threats to aquifers?
Stressors that can deplete aquifers include changes in precipitation and snowmelt patterns; withdrawal of ground water for drinking, irrigation, and other human uses; and impervious paved surfaces that prevent precipitation from recharging ground water.
What are the examples of manmade groundwater pollution?
Human groundwater contamination can be related to waste disposal (private sewage disposal systems, land disposal of solid waste, municipal wastewater, wastewater impoundments, land spreading of sludge, brine disposal from the petroleum industry, mine wastes, deep-well disposal of liquid wastes, animal feedlot wastes, ...
What are underground aquifers?
An aquifer is a body of rock and/or sediment that holds groundwater. Groundwater is the word used to describe precipitation that has infiltrated the soil beyond the surface and collected in empty spaces underground. There are two general types of aquifers: confined and unconfined.
How do landfills and sewerage system pollute our groundwater resources?
Landfill leachate
Leachate from sanitary landfills can lead to groundwater pollution. Chemicals can reach into ground water through precipitation and runoff. New landfills are required to be lined with clay or another synthetic material, along with leachate to protect surrounding ground water.
What are four common sources of groundwater pollution?
The significant sources of contamination in groundwater are farming chemicals, septic waste, landfills, uncontrolled hazardous waste, storage tanks, and atmospheric pollutants.
How landfills can pollute groundwater?
Once in the landfill, chemicals can leach into the ground water by means of precipitation and sur- face runoff. New landfills are required to have clay or synthetic liners and leachate (liquid from a landfill containing contaminants) collection sys- tems to protect ground water.
How do humans use aquifers?
In the United States, approximately 37% of our drinking water comes from aquifers. We use groundwater every day to brush our teeth, flush the toilet, and irrigate our crops. Aquifers are a crucial part of the hydrologic cycle, the perpetual life cycle of all water on Earth.
What are threats of our groundwater supply?
Common pollutants of soil and groundwater include gasoline and diesel fuel from gas stations, as well as solvents, heavy metals and pesticides. The land and groundwater may take many years to clean up. Man-made ponds containing water produced from oil and gas activities may also contain pollutants.
What are some sources of groundwater contamination Why is groundwater pollution such a difficult problem?
Why is groundwater pollution such a difficult problem? Groundwater contamination can happen because of septic systems, landfills, and industrial activity that leaches pollutants into the aquifer recharge zone. Deep wells provide a direct method for pollution to enter groundwater.
