Reuse of treated wastewater in agriculture

“As a result of climate change, agriculture will be confronted more and more with yield losses due to drought. The use of alternative freshwater sources, such as treated wastewater from industries and sewage treatment plants, can reduce drought damage. However, this wastewater contains various
substances foreign to the environment. What are the risks of using this effluent in agriculture?”
