(example)

Even where water quantity persists, quality is declining. Agricultural runoff rich in nitrogen and phosphorus creates toxic algal blooms—a process called eutrophication. Lake Erie experiences annual harmful blooms that threaten drinking water for 11 million people. Meanwhile, plastic waste, industrial chemicals, and untreated sewage contaminate lake sediments and food webs. Lake Victoria in East Africa, the world’s largest tropical lake, suffers from hypoxia (oxygen depletion) linked to sewage and agricultural runoff, killing fish species and threatening the livelihoods of 40 million people.
