Chemicals and pesticides get into groundwater supplies through?
Sometimes referred to as groundwater contamination, groundwater pollution is not as easily classified as surface water pollution, as contamination may not be easy to recognise. Groundwater, by it's very nature, is more susceptable to contamination from sources that may not directly affect surface water bodies. Groundwater can become contaminated by those drilling for oil or gas wells. Groundwater may be polluted through a spill or ongoing realease of chemical or radionuclide contaminents into soil, polluting the aquifer below yet not the surface water body above. This is defined as a toxin plume, and as it travels it is defined as a plume front. Analysis of groundwater pollution usually focuses on the soil characteristics, geology, hydrogeology, hydrolgy and the nature of the contaminants at the site.
Which freshwater source is most important to people?
rivers, lakes, water sources, groundwater.
Why is ground water so important to us?
Groundwater not only provides water through wells, but it can replenish rivers and lakes in droughts. Groundwater constantly seeps into other water sources, so contaminated groundwater means contaminated rivers and lakes.
What are some possible causes of water contamination?
This really depends upon what it is that is being contaminated, for example, contamination of drinking water, contamination of food, contamination of soil, etc. Improper disposal of sewage, sloppiness, dirtiness, lack of purification, industrial discharges, and vermin infestation are all among the possible sources of contamination of various things.
What is the difference between renewable groundwater and nonrenewable groundwater?

Possible sources for wound contamination?
Hands, urine and stools.
What is a slogan for groundwater contamination?
Contaminate groundwater today, drink those contaminates tomorrow. Contaminating groundwater is dumb. Keep groundwater clean - for life.
What risk does this most likely pose?
contamination of groundwater
Which of these is a drawback of hydraulic fracturing?
Earthquakes
How can toxic waste can enter food through the contamination of?

What is the root cause of groundwater contamination?
a spill into a drain at a factory
What is groundwater contamination?
groundwater is water found below the ground. In many countries such as the UK, Nambia and Bangladesh, groundwater is a major water source for the population. Contamination of groundwater then, is the pollution of this water which often has major ramifications for a population. Major contaminants are nitrogenous fertilizers, and heavy metals found in the soil or rocks. Chalk and even certain types of plants have been used to combat groundwater contamination. Water hyacinth, for example, a plant found in Bangladesh was used to decrease the amounts of arsenic found in the groundwater in that country.
How can one tell if one has groundwater contamination?
One can tell if one has groundwater contamination if rain water or surface water comes into contact with contaminated soil while seeping into the ground or when liquid hazardous substances themselves soak down through the soil or rock into the groundwater.
Why is ground water free from pollution?
Groundwater is as prone to contamination as surface water. Groundwater contamination results from the infiltration of spills at the surface, leachate from tanks. pipelines and buried waste. Groundwater may also be contaminated by naturally occurring salts, metals, organics and gases in the soil.
Are ice rivers lakes and groundwater sources of salt water?
Ice, rivers, lakes, and groundwater are all sources of freshwater
Is California using methyl iodide as a pesticide yet?
Not as of September 2010. There appear to be some possible issues regarding groundwater contamination which have delayed any potential approval from the state.
What are biological sources of contamination?
Bacteria and toxins
