Waste was injected into the well from 1986 through1992. Apparently what was happening was the fluid wasencountering faults at near-failure condition," said Michael Hansen,the state seismologist. A team of Columbia University geologistsconcluded that the well caused the quakes.- Columbus Dispatch, March 21, 2011.
