environmental quality
Environmental quality
  • Deteriorating environmental quality
  • Rising levels of air and water pollution
  • Weak provision of sanitation services.
  • Huge impact on human health and morbidity
  • Delhi, Mumbai, and Chennai rank among the top ten most polluted cities in the world,
growth and environment
Growth and Environment
  • None of the rivers in India is meeting the desired quality standards.
  • In fact in some of the polluted rivers like Sabarmati, Tapi, Ganga and Godavari, the violation of standards was observed close to over 90 per cent of the sites monitored.
  • Since rivers are sink for agriculture run-offs and municipal waste also, the violation of standards cannot be entirely attributed to industrial pollution.
growth and environment1
Growth and Environment
  • The data indicates that in many rivers say Ganga in UP, Yamuna in Delhi, Damodar, Subarnerakha, Betwa, Noyyal, Bhavani etc. industries contribute most to the water pollution.
  • Though industrial pollution may account for less than 25% of the pollution load in most of the rivers, the kind of effluent waste generated by industries makes the rivers highly toxic e.g. in Ganges, Yamuna etc).

A case study of health impacts near tanneries
  • Objective – To look at the impact of water quality on mortality and morbidity of the children under age 5
  • Study area - Nakal Keni area of Pallavaram and Chromepet township of Kanchipuram district in TN.
  • The area is highly polluted by tanneries and other industries and the Palar river water is contaminated.
  • Study focus – Carried out for two groups – one near the tanneries and bit further from the tanneries
  • Sample size – 450 households
main observations
Main observations
  • Contaminated water quality added with lack of precautionary measures and lack of nutrition affects the child health.
  • This is especially prominent in areas near to the tanneries.
  • Income is not a significant factor in determining child’s health.
  • It is mainly the quality of drinking water/precautionary measures that affect the incidence of water related diseases.,
  • Some of the diseases like cold and cough can be reduced significantly by getting piped water in the residence.
  • In addition to the water quality lack of proper sanitation also adds to the incidence of water related diseases.
  • If estimated in economic terms, the burden can be very huge on the economy
