2. Processes of the Water Cycle

3. Water Pollution
Water Pollution: Any physical, biological or chemical change in the water quality that has an adverse effect on organisms or that makes water unsuitable for desired uses.
Water can be polluted from natural sources like volcanoes and landslides as well as human activities.

4. Point and Nonpoint Sources
Point sources are fairly easy to monitor and regulate.
Ex. Point sources of water pollution:
Factories
Power plants
Sewage treatment plants
Oil wells
Non-point sources of pollution are more difficult to monitor, regulate, and treat in regards to water pollution because sources tend to be periodic.
Ex. of Non-point sources
Run-off from farm fields and feedlots
Lawns
Construction sites
Logging areas
Roads
Parking lots

5. Bioaccumulation and Biomagnification
Bioaccumulation: The process by which pollutants collect in the cells and tissues of organisms
Biomagnification: The increase in concentration of pollutants in tissues of organisms that are at successively higher levels of a food chain or food web
Relation: Bioaccumulation at the lowest points of the food chain leads to biomagnification throughout the whole food chain. They also work together to magnify certain water pollutants in large predators
