Groundwater testing

An underground fire has been smoldering in the southern part of the Bridgeton Landfill for more than four years. Now the state is concerned the north quarry may also be heating up.

This story was updated Oct. 20 with a response from Republic Services — The Missouri Department of Natural Resources has ordered Bridgeton Landfill LLC owner Republic Services to study the increased groundwater contamination detected at the site.

In a letter addressed to Republic Services engineer Erin Fanning last Friday, MDNR engineer Charlene Fitch provided a detailed review of groundwater sampling reports that span from October 2014 to April 2016. The sampling was conducted by a contractor hired by Republic Services. It noted increasing levels of hazardous substances that exceed federal levels, particularly benzene, which can increase the risk of cancer to those exposed to it.

A special master has allowed the state to proceed with groundwater testing at wells in the portion of the West Lake Landfill where World War II-era radioactive waste has been detected. The decision Wednesday in a circuit court of St. Louis County comes after landfill owner Republic Services tried to stop the testing from moving forward. The tests were scheduled to begin Aug. 22, but the work was delayed when Republic Services attorney Peter Daniel wrote Assistant Attorney General Thais Folta to inform her the company would not permit the sampling.
