We conduct a contingent valuation study to estimate the willingness to pay for a point-of-use water quality technology and water quality testing services in the highlands of Guatemala. This study is unique in two ways: we measure drinking water quality at the household level through water samples collected at the household and we elicit the willingness to pay for water quality testing services. We find a significant divergence in subjects’ perceptions of water quality and the measured bacteria counts in their household water. This divergence is economically important as perceptions may play a significant role in willingness to pay for water quality improvements.
