  1. Water in its many forms -- oceans, lakes and rivers -- can become polluted in a number of ways. Among them are via untreated sewage, garbage, industrial waste, spilled oil and pesticide residue. Some of the pollutants in our water are not biodegradable. Normal biological processes cannot dispose of certain kinds of pesticides, fertilizers, oil spill remnants and even radioactive material.
