  1. The detection limit was 3.18 ng/l and values below that limit are indicated as BDL
  2. aOften referred to as interstitial water samples
  3. bDissolved samples of water were filtered through a 0.45 µM filter; total-water samples were unfiltered. Selenium was detected in 416 of the 479 (87 %) in the total, pore and dissolved water samples collected between 2007 and 2009
