Any physical or chemical change in surface water or groundwater that can harm living organisms or make water unfit for certain uses.
The addition of sewage, industrial wastes, or other harmful or objectionable material to water in concentrations or in sufficient quantities to result in measurable degradation of water quality.
sewage, industrial chemicals, heavy metals, and household cleaners are examples of materials commonly discharged into streams and rivers. In addition, chemicals from the air dissolved in rainwater, pesticides, and fertilizers leached from the land run off into water
the presence in water of enough harmful or objectionable material to damage the water's quality.
The addition of harmful or objectionable material to water in concentrations or sufficient quantities to adversely affect is usefulness or quality.
Contamination or other alteration of the physical, chemical, or biological properties of any natural waters of the state, or other such discharge of any liquid, gaseous, or solid substance into any waters of the state, as well as, or is likely to create any nuisance, or render such waters harmful, or detrimental, or injurious to public health, safety, or welfare, or to domestic, commercial, industrial, agricultural, recreational, or other legitimate, beneficial uses, or to livestock, wild animals, birds, fish, or other aquatic life.
pollution of the water in rivers and lakes
The change to water that is harmful to organisms.
Placing in or on waters any matter which changes the physical, chemical or biological condition of the waters; or introducing any matter which is likely to make the waters unclean, noxious, poisonous, impure, or detrimental to the health, safety, welfare, or property of persons, or harmful to animals, aquatic life, birds or fish.
one or more chemicals in high enough concentration in water to harm humans, other animals, vegetation or materials.
The introduction of substances that make water impure compared with undisturbed water. Usually this comes from soil erosion, introduction of poisonous chemicals from industries and spills and introduction of domestic sewage or industrial and agricultural wastes.
water that has been made unclean for aquatic life and plants by dumping in foreign objects or liquids from human activities or natural processes.
any impairment to surface water or groundwater that can make the water unfit for use by organisms
degradation of a body of water by a substance or condition to such a degree that the water fails to meet specified standards or cannot be used for a specific purpose.
Industrial and institutional waste, and other harmful or objectionable material in sufficient quantities to result in a measurable degradation of the water quality.
Water pollution is defined as a change in the chemical, physical and biological health of a waterway due to human activity. Ways that humans have affected the quality of the water throughout the planet over the centuries include sewage disposal, toxic contamination through heavy metals and pesticides, overdevelopment of the water's edge, runoff from agriculture and urbanization, air pollution, etc.
The presence of harmful material in water in sufficient quantities to result in a measurable degradation of the water quality.
Introduction of foreign substances to a water source, either toxic to life forms or creating an oxygen demand, depriving indigenous life forms of oxygen and resulting in their death.
Water pollution is a large set of adverse effects upon water bodies such as (lakes, rivers, oceans, groundwater) caused by human activities. Although natural phenomena such as volcanoes, storms, earthquakes etc. also cause major changes in water quality and the ecological status of water, these are not deemed to be pollution. Water pollution has many causes and characteristics.
