GEOLOGY

Detailed explanation-1: -Groundwater contamination occurs when man-made products such as gasoline, oil, road salts and chemicals get into the groundwater and cause it to become unsafe and unfit for human use. Materials from the land’s surface can move through the soil and end up in the groundwater.

Detailed explanation-2: -Industrial discharges, urban activities, agriculture, groundwater pumpage, and disposal of waste all can affect groundwater quality. Contaminants can be human-induced, as from leaking fuel tanks or toxic chemical spills.

Detailed explanation-3: -Materials from land’s surface can travel through the soil ultimately reaching the groundwater. For example pesticide and fertilizers can enter into the ground water supplies. Untreated waste from septic tanks and toxic chemicals from underground storage tanks and leaky landfills can also contaminate groundwater.

Detailed explanation-4: -Groundwater sources are beneath the land surface and include springs and wells. As can be seen from the hydrologic cycle, when rain falls to the ground, some water flows along the land to streams or lakes, some water evaporates into the atmosphere, some is taken up by plants, and some seeps into the ground.

Detailed explanation-5: -Industrial Waste. Industries and industrial sites across the world are a major contributor to water pollution. Marine Dumping. Sewage and Wastewater. Oil Leaks and Spills. Agriculture. Global Warming. Radioactive Waste. 09-Sept-2019
