New documents related to the cleanup of a 1,4 dioxane groundwater plume in the Ann Arbor area, resulting from contamination by the former Scio Township manufacturing site of Gelman Sciences (now owned by Pall Corp.), have been posted on the Michigan Dept. of Environmental Quality website. Specifically, on Oct. 26, 2011, Pall filed a petition with the court stating that “if it is required to install additional compliance monitoring wells it will dispute the location of such wells.” In a response filed Nov. 7, the state argued that a consent judgement issued by the court doesn’t prohibit the installation of additional monitoring wells for the purpose of monitoring compliance with court-ordered cleanup. The state further argues that Pall’s proposed monitoring-well network is inadequate. [.pdf of state's response to Pall petition]
A Dec. 21 dispute resolution hearing has been set at 1:30 p.m. in the courtroom of Judge Donald Shelton of the Washtenaw County Circuit Court. For background on the dioxane contamination and cleanup, see Chronicle coverage: “Residents Frustrated by Dioxane Decision.” Additional information is also available on the websites for Scio Residents for Safe Water and the county’s Coalition for Action on Remediation of Dioxane (CARD).
