Rain is often described as a natural cleanser. Yet when the atmosphere contains sulphur dioxide, nitrogen oxides and other pollutants, rainfall can become significantly more acidic than normal. This phenomenon,…

Acid rain is often introduced with a simple formula: atmospheric pollutants react with water, forming acids that return to Earth in rain, snow, fog or dry particles. The chemistry is…

Aquifer recharge is often presented as a practical response to water scarcity. By allowing rainwater, treated wastewater or surface water to enter underground formations, communities can store water for dry…

Acid precipitation is often associated with images of damaged forests, eroded statues and polluted lakes. But its effects on water quality are more complex than the term “acid rain” suggests.…
