TABLE 1.

Detection and levels of vanA measured by qPCR in water and sediment at three sites near the origin (within 800 m) of the sewage spill over eight sampling dates^a

^aSample limits of detection were 4 gene copies per 100 ml water and 6.7 × 10³ gene copies per 100 g sediment. Day 1 postspill is considered to be 1 October 2014. Note that access issues prevented sampling at all sites on all dates; data analysis focuses on site NC-03 where samples were collected on each sampling date.

^bND, not detected.

^c—, not measured.

^dDNQ, detected but not quantifiable.
