Water can be polluted by
Organics:
* Hydrocarbon * Solvents * Fuels * Phenols * PAH * Alcohols * Ketones * Aldehyde * Sewage * organic plant or animal waste
Inorganics:
* pH * Acids/alkali * Ammonia * Nitrite/Nitrates * Metals * Silt * Radioactive material * toxics
Pollutants. This is in my science homework also :)
Rain water is composed of water molecules, which are made up of two hydrogen atoms and one oxygen atom (H2O). Additionally, rainwater can contain various other substances dissolved in it, such as minerals, gases, and pollutants, depending on the environment it passes through.
Chloroform and chloramine are two pollutants that can sometimes be found in shower water mist air and can be damaging to inhale. Both chemicals can irritate the respiratory system and may contribute to asthma and other respiratory issues with long-term exposure.
Quantitative Pollutants: The substances which are already present in the environment, but are termed as pollutants when their concentration (quantity) increases in the environment. eg. CO2 is present in the environment in greater quantity than normal and is hence termed as a quantitative pollutant.
Cumulative pollutants are substances that build up over time in the environment or living organisms, such as heavy metals or persistent organic pollutants. Noncumulative pollutants are those that are not stored in the environment and do not accumulate in organisms, like volatile organic compounds or some pesticides.

Pollutants
Whenever harmful substances such as sewage, toxic chemicals, silt, etc.., get mixed with the water, the water becomes polluted. The substances that pollute water are called Water Pollutants
Harmful substances in the air, water, or soil are called pollutants. These pollutants can include chemicals, toxins, heavy metals, and other harmful substances that can negatively impact human health and the environment.
It removes the particles of all the other substances in the water like pollutants....
Harmful substances in air, water, and soil are typically referred to as pollutants. These pollutants can include chemicals, toxins, and other contaminants that can negatively impact human health, ecosystems, and the environment. Efforts are made to monitor and regulate these substances to minimize their effects.
secondary pollutants are pollutants that form when primary pollutants react with other primary pollutants or with naturally occurring substances
Air and water containing substances that are harmful for us and our environment is said to be polluted and the harmful substances are known as pollutants.
Pure water is considered neutral, with a pH of 7. However, water can become acidic if it comes into contact with certain substances or pollutants.
Neither crops nor cows are pollutants. Pollutants are substances which pollute or contaminate essential life "elements" of the Earth, like air, water, and earth. While such commodities and animals do contribute to substances which are considered pollutants, such as pesticides, petrolleum-based fertilizers, fossil fuels emitting carbon dioxide, methane gas, and nitrous oxide, respectively, they are not all bad because they are not by-products themselves as all pollutants are.
Oil and wood are two substances that will float on water due to their lower density compared to water.
Two examples of solid substances are ice (solid water) and salt.
