Air Monitoring during soil remediation

EPA is conducting soil remediation activities for approximately two weeks during October 2011. Contaminated soils are being excavated and hauled offsite to an approved landfill. During soil excavation and backfill activities, we will collect air samples each day to monitor the ambient air for volatile organic compounds (VOCs). We will not collect air samples when it is raining or on weekends (no excavation will be going on then). We will post analytical results daily so that residents and community members can view the data.

At the end of each day, the four summa canisters that have been taking readings will be sent to a lab for analysis. We are measuring approximatly 30 different VOCs using the standard lab method TO-15. These results will be compared to the Michigan ambient air standards. The analysis takes 24 hours.

Background

Grand Traverse Overall Supply was a commercial laundering and dry cleaning facility. GTOS began laundering operations in that building in 1953. These machines were removed during the1980s. Activities at the site between 1955 and 1968 included construction of a dry well and seepage lagoons to collect waste. In 1977 the facility began discharging waste to the sanitary sewer. A year later, the Michigan Department of Environmental Quality (MDEQ) discovered groundwater contaminated with volatile organic compounds (VOCs) such as trichloroethylene (TCE) and perchlotoethlyene (PCE), impacting at least 10 wells. One of the wells supplied water to an adjacent elementary school. Contaninated wells were abandoned and new wells were drilled. The waste lagoons were drained and filled with gravel, and the contaminated soils around the dry well and on-site barrels of waste sludge were removed in the 1970s.
