Mark Ruffalo has begun a nonprofit that provides a more accurate read of contaminants in water; the designer of the method says it is more accurate than what the gov't uses.

"Ever since oil giant BP used his product as part of the cleanup after the Deepwater Horizon oil spill in 2010, Scott Smith has traveled the world pitching his special sponge technology. 

"He brought it to disasters in China, Arkansas, Virginia, Canada and even Italy, where in 2012 he tried to convince Italian officials to use his plastic foam for mopping up any olive oil that might leak from the wrecked Costa Concordia cruise ship. 

"Now Smith has brought his absorbent foam stylings to Flint, Michigan, where a negligent government let residents drink lead-tainted water for more than a year. He’s there not as a businessman but as the chief technology officer for Water Defense, an environmental nonprofit actor Mark Ruffalo founded in 2010. Smith says his “WaterBug” technology can detect contaminants better than the government can."--Arthur Delaney, the Huffington Post
