ELKHART, Ind. There's a new focus for Elkhart officials trying to reduce mercury levels in waste water that comes from the city's treatment plant: dentists offices.
At the end of the year, the city was notified by the Indiana Department of Environmental Management that average mercury levels in three months of the year exceeded the allowable limit.
The city will now be asking dentists to use separators which will capture the mercury that's used in some fillings, before it gets into the water.
The program will be voluntary, but officials say it could become mandatory in the future.
