Types of water pollution other body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen, toxic tides. Water pollution: infectious agents: main source of waterborne pathogens is untreated and improperly treated human waste pathogens. Rubble left behind from in 1972, still in the environment. We still have it in our systems. productivity mining. Ehsc 3060 feb 22, 2017: runoff of pesticides from high-use areas fields, roadsides, golf courses, oxygen solubility in water decreases as temperature increase, species requiring high oxygen levels are adversely affected by warming.
