This document discusses different types of environmental pollution including water, air, land, and noise pollution. It provides details on the causes and effects of each type. Water pollution is caused by improper sewage disposal, fertilizer run-off, oil spills, and chemical dumping and can spread diseases. Air pollution comes from solid and liquid particles and gases from sources like vehicles and industry, and causes heart disease, lung cancer, and respiratory illnesses. Land pollution involves depositing waste on land and underground, and is caused by activities like deforestation that can contaminate soil and groundwater.

underground
in a manner that can
contaminate the soil
and groundwater.
