TI alternative site clean up presses on Herald Democrat Sherman gave Texas Instruments a pat on the back last week for its alternative efforts to clean up its production site. The city formally voiced support April 19 for Texas Instruments as it seeks a municipal setting designation: a an alternative form of clean up for industrial sites. The designation relieves industrial site owners from some responsibilities for site clean up in situations where the groundwater is never used for potable purposes and contamination poses no threat to neighboring areas and existing water resources. "Just as a reminder, the intent of such an application is to provide data to the city to show that the groundwater contamination from past activity is at safe levels and or contained and not a threat to potable wells or aquifers," said Wayne Lee, Sherman Director of Engineering.
