True
No. Sometimes, groundwater can run into sewage, dumps, or other places that make it polluted.

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.
It can be impossible BUT sometimes , you can use a shovel or bulldozer.
Caves caused by volcanic activity are made of basalt Caves caused by dissolution due to groundwater are formed in limestone or sometimes marble. Caves also form in glacial ice due to melting. (Glacial ice can technically be considered rock.)
A. True
Permissible exposure limits are levels of exposures mandated by:
False: if the contaminated water has been collected. True: if the contaminated water is still in the ground. It is very easy to contaminate water that is in the ground or in aquifers. It is very difficult and yes, sometimes impossible to decontaminate ground water that is still in the ground.

Yes, depending on your state. Sometimes difficult to prove, but not impossible.
No. Sometimes, groundwater can run into sewage, dumps, or other places that make it polluted.
no
True
This depends on the zone: sometimes the groundwater is polluted or the rain water is acidic and contain particles collected from the atmosphere.
They are difficult and sometimes impossible to repair. Go to a salvage yard and buy a used horn. Cheapest way!
