Question

What are the main factors responsible for deterioration of quality and quantity of water resource?

Answer 1

Answer:

Many factors affect water quality

Sedimentation

Runoff

Erosion

Dissolved oxygen

pH

Temperature

Decayed organic materials

Pesticides

Toxic and hazardous substances

Oils, grease, and other chemicals

Detergents

Litter and rubbish

Substances present in the air affect rainfall. Dust, volcanic gases, and natural gases in the air, such as carbon dioxide, oxygen, and nitrogen, are all dissolved or entrapped in rain. When other substances such as sulfur dioxide, toxic chemicals, or lead are in the air, they are also collected in the rain as it falls to the ground. Rain reaches the earth's surface and, as runoff, flows over and through the soil and rocks, dissolving and picking up other substances. For instance, if the soils contain high amounts of soluble substances, such as limestone, the runoff will have high concentrations of calcium carbonate. Where the water flows over rocks high in metals, such as ore bodies, it will dissolve those metals.

Industrial, farming, mining, and forestry activities also significantly affect the quality of rivers, lakes, and groundwater. For example, farming can increase the concentration of nutrients, pesticides, and suspended sediments. Industrial activities can increase concentrations of metals and toxic chemicals, add suspended sediment, increase temperature, and lower dissolved oxygen in the water. Each of these effects can have a negative impact on the aquatic ecosystem and/or make water unsuitable for established or potential uses.

Answer 2

The main factors responsible for the deterioration of the quality and quantity of water resources are as follows:

Many factors influence the quality of surface and groundwater. Water shifting over or under the land surface can suffer physical and chemical changes.

• Major water pollutants contain microbes, nutrients, large metals, organic chemicals, oil and sediments; heat, which increases the temperature of the receiving water, can also be a pollutant. Pollutants are commonly the reason for major water quality degradation around the world.

Various factors credible for the deficiency of the water quantity are:

• High population: Water need has boosted with the raised population. As the number of humans boosts, the consumption of water also boosts.
• Increasing industries: All industries require water.
