Comments submitted on behalf of Protect Our Water Jackson Hole (POWJH),urging the Wyoming Department of Environmental Quality
(WDEQ) to promptly investigate the potential for ongoing groundwater contamination adjacent to
the Town of Jackson wastewater treatment facility. Existing groundwater data
indicates an ongoing contamination problem but monitoring was discontinued in 2012. Nearby
groundwater quality is already suffering from wastewater pollution and the facility’s fragile and
important location dictate swift action to remediate what could now be decades of groundwater
contamination from our community’s largest point source discharge of nutrients into the
watershed.
