The Los Angeles Department of Water and Power (DWP) made a splash with an ‘installation’ in one of the city’s reservoirs last week. The story began a few months ago when bromate, a suspected carcinogen, was detected in the water.  This compound is made when bromide and chlorine are exposed to sunlight. 

The Los Angeles Department of Water and Power (DWP) made a splash with an ‘installation’ in one of the city’s reservoirs last week. The story began a few months ago when bromate, a suspected carcinogen, was detected in the water.  This compound is made when bromide and chlorine are exposed to sunlight. 

After much debate, DWP decided to dump 400,000 black plastic balls to float on the surface blocking the sun’s rays and detering further contamination. This strategy ended up being quite a spectacle, resembling an art installation rather than an environmental management.  Read Treehugger's account or have a look at more images and view footage of the dramatic ‘ball drop’ courtesy of the L.A. Times.
