Answer: Increased transparency is NOT an indicator of the degradation of a water body.

pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic. Since pH can be affected by chemicals in the water, pH is an important indicator of water that is changing chemically.

Turbidity is the condition resulting from suspended solids in the water, including silts, clays, industrial wastes, sewage and plankton. Such particles absorb heat in the sunlight, thus raising water temperature, which in turn lowers dissolved oxygen levels.

The pollution from logging and Ag is more dispersed, and often less concentrated. It is a “non-point” source of pollution. But due to its ubiquitous nature, it is actually a far greater cause of water pollution than the collective impact of “point sources”. This is one of the problems facing any regulatory agency.

Demineralised water that has not been remineralized, or low-mineral content water – in the light of the absence or substantial lack of essential minerals in it – is not considered ideal drinking water, and therefore, its regular consumption may not be providing adequate levels of some beneficial nutrients.

PSA: The water damage indicator is white with red "X's", it does not mean there is liquid damage.

In bodies of water, like rivers, higher levels of total dissolved solids often harm aquatic species. The TDS changes the mineral content of the water, which is important to survival of many animals. ... It can increase then temperature of the water, which many animals can't survive in.

Why is it important to evaluate benthic macroinvertebrates? Benthic macroinvertebrates are commonly used as indicators of the biological condition of waterbodies. They are reliable indicators because they spend all or most of their lives in water, are easy to collect and differ in their tolerance to pollution.

what is the difference between soil degradation and soil erosion? soil degradation is when soil attributes required for plant growth deteriorate, and soil erosion is when soil particles are carried away by water and wind.

In terms of water quality, high levels of total suspended solids will increase water temperatures and decrease dissolved oxygen (DO) levels 1. This is because suspended particles absorb more heat from solar radiation than water molecules will.

Non-biodegradable substances affect the environment by: They contaminate soil and water resources as they cannot be decomposed by micro-organisms. These substances, when accidentally eaten by stray animals, can harm them and can even cause their death.

The two ways in which non-biodegradable substances would affect the environment are as follows: ... Use of non-biodegradable substances such as polythene results in blocking of drainage system and also harms animals when they are eaten by animals.

Elizabeth Y. Their cells show a beautiful symmetry, which distinguishes them from all other algal groups. Like many other algal species, desmids are important indicators of water quality. Their occurrence provides information on environmental conditions such as pH, conductivity and trophic state of a water body.

The local aquatic ecosystem can be damaged by thermal pollution, especially if it is dramatic, as in copious amounts of warm water being dumped into a chilly pond or bay or river. “Thermal shock” can kill off insects, fish, and amphibians. This sudden loss of life causes further issues with the ecosystem.

Thermal pollution decreases water quality through any process which causes changes in ambient water temperature. ... This simple use of heating or cooling water can have large effects to the oxygen levels in a body of water which impacts local ecosystems and the environment.
