Sagot :
The most crucial element in how the general public perceives water quality is water clarity. In general, lakes that are unproductive (low in nutrients) have a clarity greater than 5 meters. Lakes with moderate productivity range in depth from 2 to 5 meters.
The classic "water quality" indicators that the majority of people are familiar with are physico-chemical markers. They consist of nutrients, pH, temperature, salinity, and dissolved oxygen. How far down down the water column light may travel is determined by the quality of the water. While turbid waterways are characterized by large levels of suspended particles that obscure visibility by absorbing and reflecting light, clear waters are characterized by low quantities of suspended soil particles and/or algae. Antidegradation, designated uses, and water quality criteria make up the three parts of water quality standards. The level of water quality required to sustain a certain designated use is represented by water quality criteria. Ice is frozen water that has solidified. Because the molecules of water expand as it freezes, ice is less dense than water. Water that is liquid is moist and fluid. This is the type of water that we are most accustomed to. The vapour of water, a gas, is constantly present in the air around us. Temperature, dissolved oxygen, pH, conductivity, ORP, and turbidity are among the variables that are regularly sampled or checked for water quality. Secchi discs (which measure the transparency of the water), probes, nets, gauges, and meters are just a few of the many tools scientists use to assess the quality of the water.
