Sanitation and Hygiene

Groundwater contamination is a serious, but relatively ignored issue in the country. This contamination occurs in either through geogenic or anthropogenic means. Fluoride contamination is one such example of geogenic contamination that is widely found in the Kolar district of Karnataka. However, the fluoride levels in the town of Mulbagal are lower than those in the surroundings. Earlier, a study was conducted on the impact of pit toilets on the groundwater in the area. The present paper investigates the presence of any link between these two phenomena.

This document by Ministry of Housing and Urban Poverty Alleviation provides guidelines for the low cost sanitation scheme. The main objective of the scheme is to convert the existing dry latrines into low cost flush latrines and to construct new ones.

This article in Economic and Political Weekly,  by analysing various budget documents, attempts to capture the quantum of budgetary outlay for Water and Sanitation Services (WSS) in the slums of Bawana and Bhalaswa in Delhi. Further it captures various systemic weaknesses that impede the effective delivery of WSS in these two slum areas. 

The number people practicing open defecation in India is more than 600 million. Though the access to improved sanitation has increased since 2000 the pace of change has been slow. If the current trend continues then it will be difficult for the country to meet its Millenium Development Goal for sanitation. Thus accelerating access to and use of toilets and hygiene practices have become a national priority.

The Himalayas are inhabited by 40 million people, most of whom are dependent on agriculture and animal husbandry. The prevalent water scarcity also means a lack of water for sanitation. In this case, both open defecation and conventional sewerage pose a health risk. Conventional toilets not only consume a lot of water, but the effluent also pollutes groundwater.
