Table 6. Comparison of laboratory results for environmental and quality-control samples for 9 wells in the Fraser River watershed, 1998-2001.-Continued
[All water-quality constituents are in the dissolved form except for total coliform bacteria, MBAS (methylene blue active substances), and radon-222. no, number; Env., environmental
sample; QC, quality-control
sample; Conc. diff., difference in concentration between environmental sample and quality-control sample; RU diff., absolute difference in lowest rounding unit; mg/L, milligrams per
liter; shaded cells represent differ-
ences greater than 1 rounding unit; <, concentration less than the laboratory reporting level; E, estimated; nc, not calculated; ammonia, un-ionized ammonia [NH3] plus ammonium [NH4'];
nitrate is nitrate plus nitrite;
--, no data; col/100 mL, colonies per 100 milliliters; pCi/L, picocuries per liter. For calculations, "less than" (<) concentrations are presumed to be zero]
