Permissible exposure limits are levels of exposures mandated by:
Purifying contaminated groundwater can be challenging, as it can involve complex treatment processes depending on the type and extent of contamination. In some cases, it may be difficult or even impossible to completely remove all contaminants from groundwater, especially if they are present at high concentrations or are persistent pollutants.
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.
No, not all groundwater is clean. Groundwater can become contaminated by pollutants from various sources such as agricultural activities, industrial activities, and improper waste disposal. It is important to protect groundwater sources from contamination to ensure its cleanliness for drinking and other purposes.
Yes, in artesian wells, groundwater under pressure naturally rises to the surface without the need for pumping. This occurs when there is a confined aquifer with enough pressure to push the water up through the well. Artesian wells are a result of the geological conditions that trap and pressurize the groundwater.
True
This depends on the zone: sometimes the groundwater is polluted or the rain water is acidic and contain particles collected from the atmosphere.
Relatively is an adverb.
sometimes yes as it may have many impurities which are harmful for us.
