Detailed explanation-1: -Turbidity is caused by particles suspended or dissolved in water that scatter light making the water appear cloudy or murky. Particulate matter can include sediment-especially clay and silt, fine organic and inorganic matter, soluble colored organic compounds, algae, and other microscopic organisms.

Detailed explanation-2: -3) Physical pollutants:-Physical pollution is change in physical properties of water e.g. temperature, colour, turbidity, suspended solids etc. It is caused due to waste heat, construction, eroded stream banks, mining sites etc.

Detailed explanation-3: -Presence of chloride is a very common cause of well water pollution that occurs due to the leaching of salts from soil to well reservoir of water. Although, chlorides have mild effects on living organisms, their excessive intake may cause some serious damage or poisoning to the living body.

Detailed explanation-4: -Point-source pollution can increase turbidity through the addition of suspended solids and colored effluent (wastewater) to a body of water. For water quality, common examples include discharge pipes from factories and wastewater treatment plants.

Detailed explanation-5: -Physical properties of water are related to the appearance of water, namely, the color, temperature, turbidity, taste, and odor.
