Thank you for the opportunity to help you with your question!
What I know about groundwater pollution: Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way down into groundwater. It can also occur naturally due to presence of a minor and unwanted constituent, contaminant or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution.
What I want to know about groundwater pollution: If treatment or remediation of polluted groundwater is deemed to be too difficult or expensive, then is abondoning the use of this aquifier's groundwater and finding alternative source of water the only other option?
Please let me know if you need any clarification. I'm always happy to answer your questions.
What I have learned from groundwater pollution: Pollution can occur from on-site sanitation, landfills, effluent from wastewater treatment plants, leaking sewers, petrol stations or from over application of fertilizers in agriculture. Pollution can also occur from naturally occurring contaminants like arsenic or fluoride. Using polluted groundwater causes hazards to public health through poisoning on spread of disease.
