Lost Chinese groundwater

Pollution caused by ion exchange regeneration waste fluid: Monitoring in 200 cities shows that 55% have poor groundwater quality. Sources of pollution include seepage from industrial pits and wells, urban sewage discharge, as well as the use of fertilizers and pesticides in farmland. Chinese experts discovered in 2002 that sodium ion exchange regeneration waste fluid causes permanent damage to groundwater; 2–5 kilograms of salt must be discharged into the ground for every ton of softened water produced. A city of moderate size or larger discharges hundreds of thousands of tons of salt into the ground each year, which increases the risk of hypertension, heart disease, and cancer among humans. The United States banned the use of sodium ion exchangers in 2001
Water resources are an essential resource for human survival and health; failure to manage them promptly will lead to serious consequences!
