Superfund National Priorities List EcoShelf evaluated data from several rounds of periodic monitoring conducted by the government in an attempt to develop data to justify listing of an operating industrial plant on the Superfund National Priorities List.

At first glance, the data collected indicated that contamination serious enough to justify listing allegedly was occasionally observed at and below portions of the site. In light of the fact that this was an operating plant, it would be expected that if the source of the contamination were related to site operations and conditions, the observed contamination would be observed continually rather than occasionally. The government, unable to explain the occasional observations, wanted to proceed with listing and require the client to undertake extensive investigative work at significant expense and resource commitments.

Our analysis of the data and background documents was successful in relating the apparent data anomalies to periodic data quality and quality control issues at the different test laboratories used by the government for each round of samples collected from the site. The site ultimately was not listed on the Superfund.

We have also worked on matters involving quality control issues in manufacturing.
