What's the Problem?

The California Water Resources Board issued the drinking water advisory [1.] on August 23, 2023, after a water line in Imperial Beach tested positive for E.coli, indicating the water could be contaminated with human or animal waste, according to NBC San Diego [2.].

Residents of affected areas were urged to boil their water through the weekend and some schools canceled classes as a result of the problem.
