3. Rural Large population is still dependent on unsafe sources of water which are highly polluted, for direct consumption for eg. Rivers, lakes, ponds and tube wells Urban India is doing better than many other countries in the world for drinking water through treated pipe water supply Drinking Water Scenario in India

4. India has made “moderate” progress in reducing open defecation rates among its population and has succeeded in providing access to improved drinking water to more people in urban and rural areas The 31 per cent reduction in open defecation in India alone significantly influences regional and global estimates (Progress on Sanitation and Drinking Water, 2015 update and MDG Assessment, UNICEF and World Health Organization) Population OD India OD Low Developing Countries(LDC’s) Urban12%6% Rural65%30%

5. Impact of Drains in Delhi on groundwater Ministry of Earth Sciences The project work was planned specially keeping in view the problem of groundwater contamination in Indian context through unlined drains which are over loaded, with sewage waste from huge urban population and also waste from industries, lysimetric studies are important to know the possible sources and types of groundwater contamination through leaching

12. Heavy metals detected

13. Recommendations Lining of the drain through concrete would cut the leaching of contaminants Installing Sewage Treatment Plants (STPs) at the sewer before sewage release into drains would further prevent overloading of drains with contaminants Effluent Treatment Plants by industries must be enforced and checked strictly to avoid the release of toxic chemicals in drains

14. Zero Discharge of Effluent Domestic Use Process Use STP ETP ETP & STP treated water Tertiary Treatment Fresh Water Use for Horticulture

15. The government could also consider subsidizing sanitation projects at the level of individuals or community and also play a bigger role -providing community latrines like toilet blocks -distribution of soaps -inculcating hygienic habits starting from school children Projects like Sulabh need to be encouraged further and strengthened The private corporate sector can also be tapped to participate in this endeavor through resources under Corporate Social Responsibility (CSR) Only then by 2019, we can fulfill our dream of every household having total sanitation

18. Farmers use higher doses out of their ignorance above the prescribed dosages assuming that the pesticide formulations are either adulterated or do not have the prescribed active ingredient of optimum quantity This leads to severe contamination of the soil and water besides the high pesticide residues in agricultural produce Heavy use of pesticide may contaminate the nearby streams by runoff water and also leach down to contaminate the groundwater

20. Recommendations Rigorous legislation and regulations to control pesticides Training programs for personnel to inspect and monitor the use Extension services to farmers for judicious use of pesticides and awareness about the harmful levels of pesticides in the water which in turn adversely affect the environment and public health If pesticides are ingested above MRL values, they are carcinogenic and also cause nausea, dizziness, confusion, respiratory paralysis, skin irritation and problem with the development of early childhood Restricting the use of pesticides having higher potential for leaching beyond national regulatory levels Proper quarantine needs to be imposed to check the sale of banned and adulterated pesticides

21. New pesticide molecules like synthetic pyrethroids that degrade easily should be made available at a cheaper rate to the farmers Promotion for the use of integrated pest management methods need to be popularized amongst the farmers for the judicial use of pesticides along with cultural and mechanical control methods of pests Promotion of organic farming in farmers to obsolete the use of pesticides Popular articles to be published for public awareness for regarding the pesticide residues found in water and messages for the proper disinfection, filtration system through adsorption and boiling of the water
