How can pollution affect the water cycle? How much of our drinking water comes from groundwater? How does water pollution spread? How is groundwater naturally contaminated? How do humans affect the water cycle? How are chemical elements recycled in our environment?
How is groundwater filtered? How does water leave an aquifer? How does groundwater become acidic? How is groundwater depleted? How is Earth's groundwater and surface water replenished? How do nitrates get into drinking water? How can a confined aquifer become contaminated?
Groundwater comes to us mostly clean and free from pollution, but it can become contaminated, making it unfit for human use. Some of the most common contaminants are gasoline, oil, road salts and chemicals. One of the biggest sources of groundwater contamination is corroding, cracking or leaki...
