When soil particles or other organic particles are suspended in water, it can become brown and murky. Scientists measure turbidity to find out how clear the water is. High turbidity brown, murky water can block sunlight. Soil particles suspended in water also absorb heat, which can cause water temperature to rise, and particles can become [...]

The salt found in sea water is sodium chloride, which is the same compound as table salt. The typical salinity, or salt content, in surface sea water is 33 to 37 grams of salt per liter of water. Salinity varies in different parts of the ocean; sea water at the equator and the poles tends [...]

Contamination of groundwater, which supplies humans with much of their drinking water, is often due to the intrusion of salt water. If too much much salt water enters fresh groundwater supplies, it can render groundwater unsuitable for human use. Saline infiltration can occur as a result of over pumping from groundwater aquifers, and the presence [...]
