Environmental authorities in each country state that sourceless pollution is the main reason behind the increase in rainwater pollution. Pollution from non-point sources is removed from suburban and urban areas.

Due to the widespread use of concrete and asphalt in residential environments, polluting causes are carried from these impenetrable surfaces into storm sewers directly into state waterways. The hard surface makes it easy to clean any grease, gasoline, antifreeze, or pet waste left on the floor in the storm drain.

Every drop or spill of these and other by-products of city life is constantly being washed down the drain. These substances contribute to the pollution of rivers and streams. This constant increase in pollution causes a constant decline in the integrity of the water system. Rainwater pollution is a major problem.

Thousands of kilograms of pollutants enter the water every day. Some of these harsh chemicals are introduced into the ecosystem. They are absorbed by or attached to fish and wildlife, creating unhealthy habitats for fish and birds, as well as humans.

The scale of the pollution problem increases with the spread of civilization. To protect the safety and integrity of these water resources, many cities apply their own training, policies, and fines to industry and individuals.

While the industry holds a higher standard for implementing this process, non-privately sourced pollutants are the biggest threat. There is a clear statement in the CWA guidelines that it is illegal to release pollutants into waterways.
