Mexican former teacher and cancer patient Blanca Estela Santos (64), resident of the Gral Pedro Maria Anaya community -built for those displaced by the construction of the Endho Dam in 1952- speaks during an interview with AFP, in Tepetitlan, Hidalgo state, Mexico on August 5, 2024. The Endho Dam, in the state of Hidalgo, is highly polluted as the Tula River, which receives sewage from Mexico City through the Central and the Eastern Discharge Tunnels, industrial waste from the Thermoelectric Plant, the Pemex Refinery, and other companies in the area, flows into it.
