The impact of access to clean water on health of the elderly: Evidence from China

Abstract Access to clean water is a crucial part for the health of humans. Many present and previous studies have found that drinking water quality affects people’s health. Our study aims to find the association between drinking water and health of the elderly in China. Through regression analysis, the results show significant association between water facility (access to tap water) and old people’s depression level, difficulties to do daily activities and self-assessed health. The harmful chemicals in unsanitary water bring health risks to the old people. We suggest the government that investing more money on drinking water facilities is necessary to improve both physical and mental health of the elderly.
