Explanation:
Groundwater Pollution
Groundwater is one of our least visible but most critical natural resources. With rainfall, it becomes groundwater as it seeps deep into the earth, filling up cracks, crevices, and porous spaces of an aquifer, which is an underground storehouse of water. Groundwater is then pumped to the earth’s surface for drinking water.
Groundwater gets polluted when contaminants such as fertilizers, pesticides, and waste leaching from landfills and septic systems, making their way into an aquifer.
Once polluted, an aquifer becomes unsafe for humans and remains unusable for decades, or even thousands of years. Besides, groundwater can also spread contamination far from the original polluting source when it seeps into streams, lakes, and oceans.
Making groundwater free of contaminants can be difficult to impossible, as well as costly.
Surface Water
Surface water covers about 70 percent of the earth, filling our oceans, lakes, rivers, and including all blue bits on the world map. Surface water from freshwater sources other than the sea accounts for more than 60 percent of the water delivered to our homes.
