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. Materials from the land's surface can move through the soil and end up in the groundwater.

What can destroy an aquifer?
Aquifer depletion.
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 two pollutants that can seep into aquifers?
Aluminum, Chloramine, Lead, Mercury, Radium, and Uranium are just a few examples of common waterborne chemical contaminants. Runoff from industrial and agricultural areas is one of the most common ways that these chemicals get into groundwater.
What is the biggest threat to aquifers?
In addition to groundwater levels, the quality of water in an aquifer can be threatened by saltwater intrusion (a particular problem in coastal areas), biological contaminants such as manure or septic tank discharge, and industrial chemicals such as pesticides or petroleum products.
What happens if an aquifer is contaminated?
Contamination of ground water can result in poor drinking water quality, loss of water supply, degraded surface water systems, high cleanup costs, high costs for alternative water supplies, and/or potential health problems. The consequences of contaminated ground water or degraded surface water are often serious.
How do landfills and sewage 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 pollutes aquifers?
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.
Which of the following can possibly contaminate an aquifer?
An artesian well is one in which ________. Which of the following can possibly contaminate an aquifer? pesticides.
Under what circumstances does a contaminant become a pollutant?
A contaminant can be considered a pollutant when it is perceived to have an adverse effect on health or environment.
Why are aquifers bad?
Since groundwater that is very deep or below the oceans is saline, overpumping can cause the saltwater to move inland or upwards, resulting in saltwater intrusion, which can contaminate fresh drinking water. And when aquifers are overpumped, they can collapse, forever reducing their capacity to store water.
What are threats of our groundwater supply?
Industrial discharges, urban activities, agriculture, groundwater pumpage, and disposal of waste all can affect groundwater quality. Contaminants can be human-induced, as from leaking fuel tanks or toxic chemical spills.
What is the major threat to the Ogallala aquifer?
The true threat is posed by agriculture as it's currently practiced on the Great Plains by the farmers themselves, many of whom opposed the pipeline vehemently. The aquifer is being wasted and polluted. Wasted, that is, on corn, a thirsty crop that requires over 20 inches of irrigation water in parts of the Plains.
