b. Concentrations (mg/L) of TPH in water samples contaminated with GRO
compounds. The reference laboratory analyzed GW-10, 11, 12, and 13 after 6
days, GW 14, 15 and 16 after 29 days, and the rest after 14 days of refrigerated
storage. Samples were analyzed at CRREL after 9 days of refrigerated storage.
