Unveiling The Hidden Pollutants: What's In Our Water?

Water is a universal solvent that can dissolve many substances, making it susceptible to pollution. Human activities that generate domestic sewage and toxic waste cause water pollution by contaminating water with disease-causing microorganisms and poisonous substances. Oil spills are another source of water pollution that have devastating impacts on surrounding ecosystems. Nonpoint source pollution, which includes agricultural or stormwater runoff, is the leading cause of water pollution in U.S. waters.

Agricultural runoff

The runoff can also contaminate groundwater, which is one of our least visible but most important natural resources. When rain falls and seeps deep into the earth, filling the cracks, crevices, and porous spaces of an aquifer, it becomes groundwater. However, human activities that generate domestic sewage and toxic waste can cause water pollution by contaminating water with disease-causing microorganisms and poisonous substances.

In addition to agricultural runoff, other sources of water pollution include oil spills, which can have devastating impacts on surrounding ecosystems and cause the death of many different marine species. Sewage can also promote algae growth, which can lead to eutrophic "dead zones". Microplastics are another concern, as they can become concentrated in humans who consume seafood because of biomagnification.

Oil spills

Water pollution is a worldwide problem affecting one in every three people on the planet, according to the United Nations (UN). Water pollution is water whose composition has been changed to the extent that it is unusable. It is toxic water that cannot be drunk or used for essential purposes like agriculture, and which also causes diseases like diarrhoea, cholera, dysentery, typhoid and poliomyelitis that kill more than 500,000 people worldwide every year.

Water is a universal solvent that can dissolve many substances. While this is a wonderful quality that we take advantage of for everyday tasks such as cooking, cleaning and taking medication, it is also the exact quality that causes water pollution. Human activities that generate domestic sewage and toxic waste cause water pollution by contaminating water with disease-causing microorganisms and poisonous substances. Oil spills are another source of water pollution that have devastating impacts on surrounding ecosystems.

Nonpoint source pollution is contamination derived from diffuse sources. These may include agricultural or stormwater runoff or debris blown into waterways from land. Nonpoint source pollution is the leading cause of water pollution in U.S. waters, but it’s difficult to regulate, since there’s no single, identifiable culprit. Transboundary pollution is the result of contaminated water from one country spilling into the waters of another. Contamination can result from a disaster—like an oil spill—or the slow, downriver creep of industrial, agricultural, or municipal discharge.

Sewage

Water pollution is a worldwide problem affecting one in every three people on the planet, according to the United Nations (UN). Water pollution can be caused by human activities that generate domestic sewage and toxic waste, contaminating water with disease-causing microorganisms and poisonous substances. Sewage can promote algae growth, which can eventually result in eutrophic “dead zones” where aquatic life cannot survive because of a lack of oxygen.

Water is a universal solvent that can dissolve many substances, and this is a wonderful quality that we take advantage of for everyday tasks such as cooking, cleaning and taking medication. However, it is also the exact quality that causes water pollution. Every time it rains, fertilisers, pesticides, and animal waste from farms and livestock operations wash nutrients and pathogens—such bacteria and viruses—into our waterways. Nutrient pollution, caused by excess nitrogen and phosphorus in water or air, is the number-one threat to water quality worldwide and can cause algal blooms, a toxic soup of blue-green algae that can be harmful to people and wildlife.

Water pollution can’t be contained by a line on a map. Transboundary pollution is the result of contaminated water from one country spilling into the waters of another. Contamination can result from a disaster—like an oil spill—or the slow, downriver creep of industrial, agricultural, or municipal discharge. Oil spills are another source of water pollution that have devastating impacts on surrounding ecosystems.

The main water pollutants include bacteria, viruses, parasites, fertilisers, pesticides, pharmaceutical products, nitrates, phosphates, plastics, faecal waste and even radioactive substances.
