Water pollution is bad and the pollution is mostly made by humans because of prior to industrialization, water pollution was usually caused by contamination from animal and human waste, leading to outbreaks of cholera and other waterborne diseases. Before the Industrial Revolution in the nineteenth century, humans produced relatively small amounts of refined metals and organic materials. The production of various alloys of copper, tin, lead, and zinc by heating the mineral ores or by using natural copper metal was also minor. During the Industrial Revolution, however, people began to produce cast iron on large scales, burning charcoal to heat iron ores at high temperatures. They also used other methods to refine other metals, such as nickel,

In addition, growing urban populations produced concentrations of untreated human and animal wastes and associated disease-producing organisms in water bodies.
First off Humans mine many elements and use them for manufacturing and other purposes faster than these elements weather out of natural rocks, producing a variety of atmospheric and water pollutants. Fertilizers have high concentrations of soluble nitrogen and phosphorus compounds, and animal wastes contain high levels of nitrate. The use of fertilizers thus can produce high nitrate (a nitrogen-oxygen compound) and phosphate (a phosphorus-oxygen compound) in natural waters. Nitrate can combine with hemoglobin so that oxygen transport in the body is inhibited. This is a potentially serious threat to infants. Water high in phosphorus can stimulate the growth of organisms such as algae. As the abundant algae die and drop to the bottom of a body of water, they may use up the dissolved oxygen in the water, which may, in turn, cause fish to die. Another major pollutant in water results from the acidity produced by acid mine drainage and acid rain. Acid mine drainage results from the chemical reaction of sulfide minerals such as pyrite (iron sulfide)
