What is the difference between point and nonpoint sources of water pollution

Here are a few examples of non-point source pollution the Marine Debris Program worked on. A grant from NOAA funds work that includes the removal and disposal of debris that accumulates behind large trash booms designed to block debris from flowing into the ocean. Working with volunteers and trained crew, ITN created a kayak-based cleanup operation to remove about 40, pounds of marine debris from Shuyak Island. The island — a remote location with critical habitat for numerous species of birds, fish, and marine mammals — accumulates large amounts of marine debris because of ocean currents and winds.

When excessive amounts of nutrients end up in streams, why should we care? How can we treat heavy metals in rivers and streams? What are the effects of river water pollution? How are industries polluting our water resources? Why are industries polluting our water resources? What is the largest source of water pollution? Nonpoint source pollution is a combination of pollutants from a large area rather than from specific identifiable sources such as discharge pipes.

Runoff is generally associated with nonpoint source pollution, as water is emptied into streams or rivers after accumulating contaminants from sources like gardens, parking lots or construction sites. The federal Clean Water Act requires states to identify a total maximum daily load TMDL for each pollutant — the combined amount of pollution from point and nonpoint sources that the state believes a water body can accept without exceeding water quality standards.

As an example, the high carbon dioxide concentration in the atmosphere is a result of the emission of carbon dioxide from various factories worldwide, vehicles, and so on. The emitting carbon dioxide moves across the globe through diffusion. Figure 2: Runoff of Soil and Fertilizer.

Since nonpoint source pollution is diffusible, it cannot be controlled by a quick solution. Point source pollution refers to the pollution that occurs from a single identifiable source while nonpoint source pollution refers to the pollution that occurs via many diffuse sources. The discharge of effluents occurs at one point in point source pollution while the discharge of effluents over a wide area leads nonpoint source pollution.

This is the main difference between point source and nonpoint source pollution.
