Be a little bit unease. This morning, we have been checking local stores for water. Many are not open yet, but we did stop by a Walgreens a couple of hours ago. Plenty of water on the shelves there. Well, like Cleo said this all because of foaming agents in the water supply. Now, the city has not said exactly what that foaming agent is. But according to know your h2o.com in general, they can cause the water to create a foam when it mixes with air, creating a bitter oily and fishy taste. The water may also have an odor and appear cloudy. Now, on high doses, the agents can cause gastrointestinal problems. Now, meanwhile, people in the city.
