1 Introduction This sampling and analysis plan (SAP) addendum has been prepared to support ongoing groundwater remediation efforts at the 100-HR-3 Groundwater Operable Unit (OU). Remediation is being conducted under EPA et al, 2018, Record of Decision Hanford 100 Area Superfund Site 100-DR-1, 100-DR-2, 100-HR-1, 100-HR-2, and 100-HR-3 Operable Units, which was signed by the U.S. Department of Energy, U.S. Environmental Protection Agency, and Washington State Department of Ecology in July 2018. This addendum for DOE/RL-2013-35, 100-HR-3 Groundwater Operable Unit Well Installation Sampling and Analysis Plan (hereinafter called the parent SAP), contains site-specific field sampling plans for the proposed wells identified in Table 1. This addendum adopts the analytical methods, quality control (QC) acceptance criteria, and preservation and holding time guidelines for laboratory analysis (with minor changes) from the parent SAP (DOE/RL-2013-35) and TPA-CN-1100, TPA Change Notice Form: DOE/RL-2013-35-ADD12, 100-HR-3 Groundwater Operable Unit Well Installation Sampling And Analysis Plan, Addendum 12: Wells 199-D11-1, 699-98-50, 699-95-48B, 699-96-428, 199-H4-94, and 199-H3-14, Rev. 0. The analytical methods, QC, acceptance criteria, and preservation and holding time guidelines are in Chapter 2 of this document. The minor changes amount to practical quantitation limit (PQL) updates (Table 2 in ECF-HANFORD-18-0058, Practical Quantitation Limits for Groundwater Environmental Samples) for 14797-55-8 nitrate, as NO3, 14265-44-2 phosphate, and 17439-96-5 manganese. These changes arise because the changes are PQL values that have been calculated in the time between this document’s writing and DOE/RL-2013-35-ADD12, 100-HR-3 Groundwater Operable Unit Well Installation Sampling and Analysis Plan, Addendum 12: Wells 199-D11-1, 699-98-50, 699-95-48B, 699-96-42B, 199-H4-94, and 199-H3-1 (as modified by TPA-CN-1100). It should be noted that the parent SAP refers to quantitation limits as estimated quantitation limits (EQLs) which are essentially the same things as PQLs. The analytical requirements for groundwater in this document are in DOE/RL-2013-30, Sampling and Analysis Plan for the 100-HR-3 Groundwater Operable Unit Monitoring. Groundwater analytical requirements in DOE/RL-2013-30 have been reconciled with and are concurrent with those to be included in the pending new groundwater monitoring SAP DOE/RL-2017-13 ADD1 which will be included in the remedial design/remedial action work plan for the 100-HR-3 OU. Soil analytical requirements are stated in Section 5 of this document.
Waste generated under this SAP will be managed in accordance with DOE/RL-2017-13, Remedial Design/Remedial Action Work Plan for the 100-DR-1, 100-DR-2, 100-HR-1, 100-HR-2 and 100-HR-3 Operable Units, Section 6.3, “Waste Management”.

3 Well Design
Table 3 presents a summary of the anticipated drilling depths for each well and includes the anticipated screened intervals, the estimated depth to water (unconfined and RUM aquifers), and the estimated depth to the RUM surface. General well designs for unconfined and RUM well constructions are illustrated in Figures 3 and 4, respectively. Screened intervals will span the entire aquifer thickness with the top of the screen set above the high water-level mark. RUM well screens will span the aquifer thickness between confining layers. Exceptions may be made to screened interval lengths in cases of thick aquifers and specifically targeted contamination zones (i.e., screened interval set to the aquifer depths where contamination occurs and to accommodate a thin semi-confining layer between the RUM aquifer interval and the bottom of the unconfined aquifer as to not allow the filter pack to compromise the semi-confining layer [see Figure 4]).
Wells 199-D1-1 and 199-D2-14 are to be completed in the unconfined aquifer as monitoring wells (Figure 3). The locations planned for these wells are downgradient of potential future remediation activities at 100-D-100 and/or 100-D-56. Water levels in the aquifer near the planned locations of wells 199-D1-1 and 199-D2-14 typically varied by about 0.25 m (0.82 ft) from late 2018 to mid-2020. Such small variability in the seasonal water-level trend would not warrant well design modification for wells 199-D1-1 and 199-D2-14. However, river levels were unseasonably low during 2019, and a difference of about a meter exists between mid-2017 and mid-2020. At these locations, the top of the screen should be set 5 ft above the static water level to accommodate possible large water-table fluctuations. Therefore, a 20 ft screen may be needed at these locations.

The well location of unconfined aquifer extraction well 199-H1-51 was selected for capturing the Horn hexavalent chromium (Cr(VI)) plume (≥10 μg/L) extension that appears to be in contact with the Columbia River. The unconfined aquifer in this area is relatively thin, and unconfined aquifer water-level responses to river stage changes are rapid. However, it is expected that this will not greatly affect the performance of well 199-H1-51 because of planned injection in its immediate vicinity. Four extraction wells (199-H1-32, 199-H1-33, 199-H1-34, and 199-H1-35) will be realigned as injection wells in FY 2021. A more stable water table is expected because of the planned injection near 199-H1-51. Therefore, no special modifications to the well design are necessary.
Typical semiconfined aquifer conditions are expected at RUM wells 199-H3-33, 199-H3-34, and 199-H6-9, and well design modifications are not expected (Figure 4). The RUM semiconfined aquifer consists of silty sand and sand layers sandwiched between upper and lower silty layers. The saturated thickness tends to range between 3 and 9 m (10 and 30 ft).
4 Sampling Cr(VI) contamination is known to be present in the uppermost RUM water-bearing unit in the central part of 100-H, but the extent is not well defined to the north and south. Samples collected and analyzed from the RUM wells as part of this addendum will provide information to further define the extent of Cr(VI) contamination within the uppermost water-bearing unit in the RUM for the 100-HR-3 OU at 100-H. Borehole 199-H3-33 will be advanced into the lower RUM water-bearing unit (below the uppermost RUM water-bearing unit), and samples will be collected to determine the vertical extent of Cr(VI) at that location. This location was deemed appropriate for deep sampling because it is within the central portion of the highest Cr(VI) interpolation contour in 100-H.
Figures 5 through 9 show the general lithology for each new well based on the lithology of nearby existing wells. Sampling zones and depths are estimated from these interpretations but may be modified dependent on actual conditions encountered during drilling. The preferred drilling method is Sonic because it allows continuous coring. Continuous core samples can be collected in plastic sleeves rather than sealed liners if no sampling for volatile organic compounds is specified.
The RUM lithology contains various lenses of sand, silt, and clay within the uppermost water-bearing unit of the RUM. Clarifying the continuity, thickness, and hydrologic properties of this unit will expand the ability to track, model, and remediate Cr(VI) in the RUM aquifer. Soil samples will be collected and analyzed for grain size distribution, hydraulic conductivity, and permeability. Soil samples will be analyzed for particle size distribution within the aquifer interval into which the well screen will be set to specify screen slot size and filter pack requirements, per standard practice. Hydraulic conductivity and permeability are the hydrologic properties of this unit. Hydrologic property data will be input to the hydrologic modeling framework of the RUM aquifer and used for future predictions of contaminant migration.
Both the unconfined aquifer and the RUM aquifer will be sampled during drilling to allow for early characterization of aquifer conditions. Water samples will be collected to evaluate water chemistry and contaminant levels. Post-development groundwater sample data will be used to establish initial hydrochemical conditions. The sample type, targeted geologic unit, soil and water sample estimated depths, and analytes/physical properties are presented in Tables 4 through 8. Sample locations presented in Tables 4 through 8 are general zones for sample collection, with the targeted geologic unit where the sample is to be obtained identified. There is no suspected contamination in the vadose zone at the RUM aquifer wells; therefore, soil samples for chemical and physical analysis will not be collected from the vadose zone above the water table. Grab samples will be collected throughout the borehole for lithologic and archival purposes.

Groundwater contaminants to be sampled in RUM wells include total chromium and Cr(VI). Technetium-99 (Tc-99), and uranium will also be sampled at well 199-H3-33 because it lies only 75 m (246 ft) north of the 183-H Solar Evaporation Basins. All sampling will be conducted as per Appendix B of DOE/RL-2013-30. Groundwater samples in the unconfined and RUM aquifer will include field water chemistry parameters.
Wells 199-D1-1 and 199-D2-14 (Figure 5) are located in an area in which the Cr(VI) plume is well defined and do not require samples to be collected during drilling. Therefore, only post-development, midscreen groundwater samples will be collected at these locations.
Figure 6 presents the geology and estimated sampling zones for well 199-H1-51, which will be an extraction well completed in the unconfined aquifer northwest of 100-H.
Well 199-H3-33 is to be installed as a RUM extraction well for Cr(VI) mass removal in 100-H (Figure 2). Figure 7 shows the estimated geology and sampling scheme for well 199-H3-33. The RUM aquifer at this location is expected at a depth of approximately 19 m (62 ft) below ground surface and range between 5 and 6 m (15 and 20 ft) in thickness. Screen lengths are expected to be 10 to 20 ft, dependent on sampling results. This borehole will be extended through the lower RUM water-bearing unit in order to determine the vertical extent of Cr(VI) contamination at this location. Deeper confined and semiconfined aquifers are often reducing environments and, therefore, special precautions should be taken to collect Cr(VI) samples with dissolved oxygen values ≥5 mg/L. Deep sampling at this location was deemed important because this well lies in the central portion of the highest Cr(VI) RUM plume concentration (≥100 μg/L) interpolation for 100-H. Radioisotope Tc-99 will be sampled as well as total uranium because of the borehole location near the 183-H Solar Evaporation Basins. Tc-99, and uranium are all known to have been associated with the 183-H Solar Evaporation Basins.
The geology at the location of well 199-H6-9 is expected to be similar to the geology encountered at well 199-H3-33 (Figure 8). Soil and water samples at well 199-H6-9 will be taken at similar depths as well 199-H3-33, but the 199-H6-9 borehole will not be advanced as deep, because it is in an area distal to the highest expected Cr(VI) concentrations and is not near any known waste sites. Well 199-H6-9 is to be installed as a RUM monitoring well for plume delineation in the south-eastern area of 100-H(Figure 2). No well design modifications are expected for this location.
Well 199-H3-34 (Figure 9) is to be installed as a RUM monitoring well for plume delineation in the northern area of 100-H (Figure 2). Depth to the RUM aquifer at this location is estimated to be about 13 m (43 ft) below ground surface. Screen length is expected to be 3 m (10 ft) because the RUM aquifer zone at this location is expected to be thinner than to the south. No well design modifications are expected for this location.
Figure 10 provides the generalized hydrogeology for the 100-HR-3 OU. Geologic zones where soil and water samples for chemical and/or physical analyses are to be collected are also indicated. Unconfined aquifer and vadose zone material is anticipated to be Hanford sand and gravel, with the 100-D Area having a layer of Ringold Formation member of Wooded Island – unit E (Rwie). The Hanford formation facies consists of moderately to very poorly sorted, large- to very large-, cobble- to boulder-sized clasts in open framework gravels that include discrete sand lenses, with little or no silt and clay-sized material. The Rwie is a dense, compact, and well-graded formation versus the looser, coarser-grained Hanford Site gravel-dominated facies. The Rwie is composed of fluvial matrix-supported gravels and sands with intercalated fine- to coarse-grained sand and silt layers. The silt zone noted on each figure represents the RUM material, although it may consist of clay. The uppermost water-bearing unit in the RUM (the RUM aquifer) is anticipated to consist of a silty sand material. The actual geologic material of each unit will be determined in the field.
