Turbidity is the cloudiness or haziness of a fluid caused by large numbers of individual particles that are generally invisible to the naked eye, similar to smoke in air.The measurement of turbidity is a key test of both water clarity and water quality.
When the temperature is below 0 °C, the dew point is called the frost point, as water vapour undergoes gas-solid phase transition called deposition, solidification, or freezing. In the petroleum industry, cloud point refers to the temperature below which paraffin wax in diesel or biowax in biodiesels forms a cloudy appearance.
A suspension of flour mixed in a glass of water, showing the Tyndall effect In chemistry , a suspension is a heterogeneous mixture of a fluid that contains solid particles sufficiently large for sedimentation .
Surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to channel runoff (or stream flow).It occurs when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil.
Water hardness also plays a role in when your sink should be cleaned. The harder the water, the more minerals like magnesium and calcium are in it. ... If you notice a slow drain, it could mean it ...
Flocculants are used in water treatment processes to improve the sedimentation or filterability of small particles. For example, a flocculant may be used in swimming pool or drinking water filtration to aid removal of microscopic particles which would otherwise cause the water to be turbid (cloudy) and which would be difficult or impossible to ...
Depending on water losses, precipitation, and inflow (e.g., a spring, a tributary, or flooding), the temporal result of a lake in a sink may change. The lake could be a persistent lake, an intermittent lake, a playa lake (temporarily covered with water), or an ephemeral lake, which completely disappears (e. g. by evaporation) before reappearing in wetter seasons.

Tap water can sometimes appear cloudy and is often mistaken for mineral impurities in the water. It is usually caused by air bubbles coming out of solution due to change in temperature or pressure. Because cold water holds more air than warm water, small bubbles will appear in water.
