A very large number of our people defecate in the open. It may cause water pollution and soil pollution. Both the surface water and groundwater get polluted. Groundwater is the source for wells, tube-wells and handpumps. Thus it becomes the most common route for water-borne diseases like cholera, dysentery, etc.

Prevention of water pollution

  • Water wastage is a major problem globally and we are only now waking up to the issue. Simply small changes you can make domestically will make a huge difference.
  • Treating waste products before disposing of it in a water body helps reduce water pollution on a large scale. Agriculture or other industries can reuse this wastewater by reducing its toxic contents.
  • By using soluble products that do not go on to become pollutants, we can reduce the amount of water pollution caused by a household.

Prevention of soil pollution

  • Excavation and subsequent transportation of polluted soils to remote, uninhabited locations.
  • Extraction of pollutants via thermal remediation – the temperature is raised in order to force the contaminants into the vapour phase, after which they can be collected through vapour extraction.
  • Bioremediation or phytoremediation involves the use of microorganisms and plants for the decontamination of soil.
  • Mycoremediation involves the use of fungi for the accumulation of heavy metal contaminants.
