1) Chemical Pollutants-Chemical pollutants are substances that enter into waterways and contaminate them. These include inorganic pollutants (such as heavy metals or industrial byproducts) and organic chemicals (such as pesticides or fertilizers). An example is when nitrates from fertilizer runoff end up in rivers or lakes; this causes algae blooms to occur which depletes oxygen levels leading to fish kills.
2) Thermal Pollution-Thermal pollution occurs when heat is transferred from one source to another, usually from factory processes or power plants that discharge heated waste water into rivers or other bodies of water. This disrupts the natural temperature balance of the body of water it is being discharged into and can lead to decreased species diversity as certain species may not be able to adapt quickly enough to survive these changes in temperature. For example, a power plant might dump hot wastewater into a lake resulting in increased temperatures which cause fish die-offs due excessive heat exposure over time.
3) Sedimentation-Sedimentation occurs when particulates such as soil, sand, silt, clay particles settle out of suspension in waterways due to their weight causing turbidity (cloudiness). This obscures light needed for photosynthesis thus reducing oxygen levels necessary for aquatic organisms’ survival; it also covers surrounding habitats preventing animals from finding food sources like insects living near shorelines resulting in habitat destruction over time. An example would be construction sites located near streams where loose dirt erodes away during rain events polluting the stream with high amounts of sediment loading downstream reducing its clarity severely impacting aquatic life within it eventually killing them off if left unchecked long enough .
5) Pathogens – Pathogens are microorganisms that enter our waterways via sewage discharges , agricultural run off , animal wastes etc… These pathogenic microorganisms have potential become detrimental populations within our waters depending concentrations found ; general rule thumb more pathogens means greater risk infection sickness those who come contact directly indirectly drinking swimming boating fishing potentially causing serious illnesses including death some cases since acceptable tolerable safe ranges differ between groups people . An example would be when sewage containing E coli bacteria gets discharged into rivers contaminating them leading people becoming ill exposing themselves drinking playing coming contact contaminated areas affected way places visited so please practice caution always around known polluted while outdoors activities related connected waters mentioned above listed prior combined together finally ending concludes entire list types major forms water pollution giving examples each occurred throughout article written above beginning start clearly defined labeled classified important understand issues faced today struggle against improving helping bettering state everyone’s well being future generations come later hoping successful efforts taken prevent further spread damage.
