Management of petroleum-impacted waters by monitored natural attenuation (MNA) requires an understanding of the toxicology of both the original compounds released as well as the transformation products formed during natural breakdown. Here, we report data from a groundwater plume consisting of a mixture of crude oil compounds and transformation products resulting from a crude-oil release in August, 1979 near Bemidji, MN, USA. Water samples were characterized for activation of 52 human nuclear receptor (NR) activities and 50 transcriptional pathways associated with toxic responses. Five replicate analyses were performed for each solution at strengths of 1, 3, and 10 times the sample concentration. Radar plots of...

Groundwater samples were collected in June 2018 from a background (reference) well located 200 m upgradient from the source and five wells along a flowline in the plume at 39, 68, 102, 125, and 254 m downgradient from the source. Before sampling, at least three times the water volume in the well casing was purged and field parameters (temperature, dissolved oxygen, specific conductance, and pH) were stable. Two samples from each well were collected into unpreserved 1 L amber bottles and shipped on ice overnight to a commercial lab. The two samples were extracted using dichloromethane (DCM; EPA Method 3510). One sample extract was treated with silica gel cleanup (SGC) column (USEPA method 3630C). Aliquots of the...
