pollution of water is on the increase see how

Water pollution is the deterioration of the state of water from a good condition to a bad condition which is inhabitable to man and other living things. Here, we look into the state of and ways in which environmental state of water system and management has been infected by human activities and living organisms. It is considered that the treated effluent from sewage treatment plant is not as pure as river water. This is because it contains various partially un-dissolved oxidized substances. These substances could be organic or inorganic. Therefore, for the safe keeping of our hydrosphere, industrial technology need to take responsibility for adequate supply of treated water. This should be done in conjunction with the government policies. If adequate care is not taking, there is a tendency that the future generation will suffer a lot of water borne diseases.

levels of water pollution

Water can be polluted in three different ways despite the various causes of water pollution.

  • Natural causes: this is the change in water quality due to natural occurrences; such as air borne substances, suspension when carried from the soil to water ways.
  • Non natural ways: these include all temporally induced pollution such as impure release of energy.
  • Qualitative and quantitative pollutants: here, there is an inhibition of auto purification capacity of water. {there is a permanent induced pollution}

causes of water pollution

  • Addition of toxic substances to water bodies
  • Deoxygnation
  • The effect of buffering a solution
  • Addition of suspended solids
  • Addition of human, animal and plant pathogens (sewage)
  • read more causes

requirements of water pollution

  • Irrigation purposes: water should be
  1. Clear and transparent in surface
  2. Free from phytoxins
  • Not highly saline
  1. They must be aerated adequately
  • Drinking purposes: drinking water should be of the following
  1. Be bacterial free
  2. Colorless and odorless
  • Free from poisonous substances such as nitrites
  1. Contain moderate dissolved salts.
  • Industrial purposes: it must be that
  1. They do not contain dissolved salts which are corrosive
  2. Do not contain dissolved corrosive gases
  • Do not exhibit turbulence

Natural pollution of water is due to terrestrial, structural and activities done by meteorological phenomena. Artificial causes such as industrial discharge, arable farming, human discharge metabolism  and many more. When these are purged into water bodies, the cause unhealthy environments and sicknesses such cholera, which is common in our society.

In general, Government should back up their policies with action on defaulters of water management schemes. Laws about industrial discharge should be strictly followed. Water drainage should be kept clean and avoid dumping of non biodegradable and degradable materials in them.
