How do households living in arsenic-contaminated regions value safe drinking water?

Past Event

NCAER hosted an online lecture titled “How do households living in arsenic-contaminated regions value safe drinking water?” presented by Dr. Diptimayee Nayak (Associate Professor at IIT Roorkee) and discussed by Dr. Papia Raj (Associate Professor at IIT Patna), as part of its Virtual Dialogue Room Webinar Series moderated by Dr. Reshma Roshania and chaired by Dr. Souryabrata Mohapatra on Friday, 28 June 2024, at 4:00 pm IST.

Abstract:

Access to safe drinking water is a critical concern, particularly in areas affected by arsenic contamination. The report of the Ministry of Jal Shakti, Government of India (2021), reveals that about 24 habitations from five districts of Bihar are affected by arsenic groundwater contamination, impacting about 71,946 population and their health and economic conditions. In this context, the objectives of the present study are to estimate the mean willingness to pay (WTP) for arsenic-free drinking water and determine factors that impact households’ WTP for arsenic-free drinking water in Bihar. The primary data was collected from 300 households following simple random sampling, and villages were selected through a multi-stage sampling method. The study uses a single-bound dichotomous choice method for WTP elicitation and applies a probit model to determine factors affecting households’ WTP for arsenic-free safe drinking water. The mean WTP is estimated to be ₹ 216.68 per household/month, and results find that education, income, health expenditure, awareness level and high-risk exposure to arsenic are the most influential determinants of households’ WTP for arsenic-free drinking water. Hence, the study suggests appropriate interventions by the policymakers in the arsenic-contaminated areas in Bihar.

Speaker notes:

  • “The government must prioritise providing safe drinking water, organise regular health camps and raise community awareness about the risks of arsenic contamination and safe water sources.” – says Dr. Diptimayee Nayak
  • “Health education would be instrumental in motivating communities to develop a positive attitude towards WTP for arsenic-free drinking water, reducing the burden on the public healthcare system in India.” – says Dr. Papia Raj
  • “Communities value safe water. Building awareness on arsenic risk along with ensuring safe water for all is key”– says Dr. Reshma Roshania
