Organic chemicals easily pollute the drinking water supplies and can cause long-term health problems to humans. For example, organic solvents, pesticides, dioxins, polychlorinated biphenyls, furans, and other nitrogen-containing derivatives. Excessive use of insecticides, herbicides, fungicides, and rodenticides can result in toxic compounds carried by stormwater runoff from agricultural lands, construction sites, and residential lawns to receiving waters

Some algal blooms are the result of an excess of nutrients (particularly phosphorus and nitrogen) into waters and higher concentrations of these nutrients in water cause increased growth of algae and green plants.

As more algae and plants grow, others die.

This dead organic matter becomes food for bacteria that decompose it.

With more food available, the bacteria increase in number and use up the dissolved oxygen in the water.

When the dissolved oxygen content decreases, many fish and aquatic insects cannot survive.

This results in a dead area.

Algal blooms may also be of concern as some species of algae produce neurotoxins.

At the high cell concentrations reached during some blooms, these toxins may have severe biological impacts on wildlife.

Algal blooms composed of phytoplankters known to naturally produce biotoxins are often called Harmful Algal Blooms, or HABs.

In wastewater, oraganic matter including dye, humic substances, phenolic compounds, petroleum, surfactants, pesticides, and pharmaceuticals are the most common.

Organic pollution affects the organisms living in a stream by lowering the available oxygen in the water. This causes reduced fitness, or, when severe, asphyxiation. The increased turbidity of the water reduces the light available to photosynthetic organisms. Organic wastes also settle out on the bottom of the stream, altering the characteristics of the substratum
When an organic polluting load id discharged into a river it is gradually eliminated by the activities of micro organisms in a way very similar to the processes in the sewage treatment works. This self-purification requires sufficient concentrations of oxygen, and involves the breakdown of complex organic molecules into simple in organic molecules. Dilution, sedimentation and sunlight also play a part in the process, attached micro organisms in streams play a greater role than suspended organisms in self-purification. Their importance increases as the quality of the effluent increases since attached microorganisms are already present in the stream, whereas suspended ones are mainly supplied with the discharge

The runoff of the organic matter leads to the pollution of water. Excessive growth of phytoplankton in water can also be among the causes of water pollution. In addition,organic pollutants include many pesticides and herbicides that have been used in agriculture and pest control.
EFFECT
Organic matter enters the water bodies, the microorganisms present in the organic matter utilize the oxygen available in water. Therefore, this will, in turn, cause the oxygen-dependent aquatic life to slowly diminish and die due to lack of oxygen in the water

Organic pollution of rivers by wastewater discharge from human activities negatively impacts people and ecosystems. Without treatment, pollution control relies on a combination of natural degradation and dilution by natural runoff to reduce downstream effects. We quantify here for the first time the global sanitation crisis through its impact on organic river pollution from the threats of increasing wastewater discharge due to urbanization and intensification of livestock farming, and reductions in river dilution capacity due to climate change and water extraction

Organic pollution of rivers by wastewater discharge from human activities (cities, farming, industry) affects humans and ecosystems worldwide through the global sanitation crisis. First, untreated urban sewage contains pathogens that cause a variety of diseases, including diarrhoea, globally the leading cause of illness and death.

The occurrence of organic pollutants in wastewater have increased tremendously in modern years and has become a critical concern because of their toxicity, semi volatile nature, low water solubility, high bioaccumulation and non-biodegradability under normal environmental condition.
