The Ivanhoe Reservoir in Silver Lake, near Los Angeles, is being covered with plastic black balls in an attempt to prevent the bromate count from exceeding health quality standards. There will eventually be a few million balls tossed onto the reservoir.
Too much bromate – a carcinogen – which gets created from a reaction to bromine and sunlight, is not good for you. The reservoir feeds LA, hence the need to do something about this. Someone or some group decided that the black balls will essentially shadow the lake and therefore reduce the creation of bromate.
When sunlight starts breaking down the plastic and releasing other chemicals into the water, how much will the state of California pay to remove the balls? When algae start adhering to and scumming the black balls, turning them green, who will clean them? When the lack of sunlight on the lake bottom starts affecting the ecological environment 20 feet under the water, will the environmentalists suddenly clamor to have them removed?
I smell the law of unintended consequences coming into play, real soon. This article makes it sound like there is little to worry about. I’m not so confident about that at all.
