Phase I remedial investigation report of Waste Area Grouping 2 at Oak Ridge National Laboratory, Oak Ridge, Tennessee

“…Stormflow is transient but may be a locally important pathway for water following precipitation events (Moore 1988; Solomon et al 1991). The role of the stormflow zone for contaminant transport into WAG 2 is currently being investigated by the WAG 2 SI Program.…”

“…However, these events were primarily dunng base flow conditions. Earlier storm sampling conducted in 1988 at the downstream location, MBWEIR (Solomon et al 1991), found measurable amounts of @Co associated with the suspended sediments that may have been transported from the HFIR area. The HFIR k e a subbasin discussion consists of risk and criteria exceedance results for the following subbasins that are analyzed in this assessment: HFIR, HFIR East, HFIR South, IjF-2, and MB-15.…”

“…Like Solomon et al (1991), Wickliff concluded that groundwater was the principal migration pathway for 3H; however, Sr migration was primarily in the stormflow zone.…”

“…A tracer study performed by Solomon et al (1989) revealed that "Sr added to the impoundment water was detected in downgradient groundwater well 1108 (on the northwest side of the P: RI-FMAL:VOL-3 BI'SEC-BIE.DOC D3SEPTEMBER 1995 …”

“…Graphical stream hydrograph separation techniques were used by Solomon et al (1991) to estimate that approximately 16% of the total 3H release (based on 1988 data) to Melton Branch resulted from quickflow (equivalent to stormflow and surface runoff; see Sect. B3.2.2); the balance was attributed to baseflow (discharging groundwater).…”
