Nutrient water pollution is a form of water pollution caused by excessive inputs of nutrients into water bodies. The main nutrients that cause this pollution are nitrogen and phosphorus. This type of pollution is one of the most widespread and challenging environmental problems faced by many nations. It occurs when excess nitrogen and phosphorus from agriculture, storm and wastewater facilities, use of fossil fuels, and daily domestic activities enter our waterways.

Excessive nutrients cause algal growth in lakes, rivers and coastal waters
Nutrient water pollution is a form of water pollution that occurs when there is an excessive input of nutrients into lakes, rivers, and coastal waters. The primary cause of this type of pollution is the presence of too many nutrients, usually nitrogen or phosphorus, in these water bodies. These excess nutrients stimulate the growth of algae, a process known as eutrophication.
Nutrient pollution can come from various sources. Surface runoff from farm fields and pastures, for example, can carry excess nutrients from agricultural activities into nearby water bodies. Discharges from septic tanks and feedlots can also contribute to this type of pollution. Emissions from combustion and raw sewage are other significant factors. Sewage is high in nutrients, and dumping it into water bodies can lead to cultural eutrophication.
When there is an excess of nutrients in coastal waters, it often results from wastewater treatment facilities, runoff from urban areas during rains, and farming activities. Increased nutrient pollution in these areas can have detrimental effects on the environment and human health.
The EPA has collected data and developed tools to manage and reduce nutrient pollution. Water quality criteria for nitrogen and phosphorus are established to protect and restore water bodies that have been impaired by nutrient pollution.
Excessive algal growth, a direct result of nutrient water pollution, can have significant ecological consequences. Algae blooms can produce toxins that harm people, animals, and aquatic life. Additionally, excessive algae can reduce or deplete the dissolved oxygen available to aquatic organisms, leading to hypoxia and harming aquatic life.

Nutrient pollution is a primary cause of eutrophication of surface waters
Nutrient pollution is a form of water pollution that occurs when there is an excessive input of nutrients into the water. This is a primary cause of eutrophication of surface waters such as lakes, rivers, and coastal waters. Excess nutrients, usually nitrogen or phosphorus, stimulate algal growth in these waters. Sources of nutrient pollution include surface runoff from farm fields and pastures, discharges from septic tanks and feedlots, and emissions from combustion. Raw sewage is a large contributor to cultural eutrophication since sewage is high in nutrients. Releasing raw sewage into a large water body is referred to as sewage dumping and still occurs all over the world.
Nutrient pollution occurs when excess nitrogen and phosphorus from agriculture, storm and wastewater facilities, use of fossil fuels, and daily domestic activities enter our waterways, impacting human and environmental health and our economy. Excessive algal growth can reduce or deplete dissolved oxygen available to aquatic life and, in many instances, produce toxins that can harm people, animals, and aquatic life.
The EPA has collected data and developed tools to better understand, manage, and reduce nutrient pollution in surface and source waters. Water quality criteria for nitrogen and phosphorus help to protect water bodies and restore those that are impaired by nutrient pollution.
Nutrient pollution is one of the most widespread and challenging environmental problems faced by our nation. Excess reactive nitrogen compounds in the environment are associated with many large-scale environmental concerns.

The EPA has collected data and developed tools to better understand, manage, and reduce nutrient pollution in surface and source waters. Water quality criteria for nitrogen and phosphorus help to protect water bodies and restore those that are impaired by nutrient pollution. The EPA supports and facilitates access to state progress via a StoryMap, basic and applied research, publications, and resources to help manage nutrient pollution in our nation's waters.
Nutrient pollution can be reduced through daily choices we make around the house, yard, our communities, and classrooms. Excess reactive nitrogen compounds in the environment are associated with many large-scale environmental concerns. Because there are increasingly more people living in coastal areas, there are more nutrients entering our coastal waters from wastewater treatment facilities, runoff from land in urban areas during rains, and from farming. All of these factors can lead to increased nutrient pollution.
