CHARACTERIZING BEDROCK FRACTURE ORIENTATION AND DENSITY USING FRACTURE TRACE ANALYSIS, OUTCROP FIELD MAPPING, AND GEOPHYSICAL BOREHOLE METHODS IN FOSTER, RHODE ISLAND US Army Corps of Engineers BUILDING STRONG® Jeff Schwindaman Hydrologist, US Army Geospatial Center Date: 03 November 2015

NIKE PR-79 Control Site Approx. 14 acres in NW RI Former NIKE missile defense network 1956 – 1963 TCE discovered in two on-site production wells, 3 residential wells N

Purpose of the study Fracture Trace Investigation Determine potential pathways of TCE migration by characterizing the bedrock fracture pattern at the NIKE PR79 Control Site 1. Determine the location and orientation of remotely-sensed fracture traces 2. Characterize bedrock fractures in outcrop 3. Compare results with borehole geophysical data Fracture Trace Investigation Bedrock Fracture Characterization Field Outcrop Investigation Borehole Geophysical Investigation

Site Geology Ponaganset gneiss Fine-grained quartz diorite South Foster migmatite Woonasquatucket quartzite (Acker, 1950; Frost, 1950)

Fracture Trace Investigation

Fracture Trace Analysis ? Structural trend? North – NE/SW South – NW/SE

Field Outcrop Investigation

Field Outcrop Investigation 22 outcrop locations N = 96 fractures Float vs. Outcrop? 59 % steeply dipping (≥ 60°) 3 % shallow dipping (≤ 20°) Average linear fracture density: 0.28 fractures/ ft Average linear fracture spacing: 3.57 ft/fracture Slightly to very slightly fractured (USBR Classification) Characteristic Average Minimum Maximum Apparent Length 7.6 ft 1.0 ft 26.7 ft Openness 4 (Moderately Wide; 0.03 to 0.1 ft) 1 (Slightly Open; <0.003 ft) 5 (Wide; > 0.1 ft) Moisture 2 (Dry, no evidence of water flow) 1 (Dry, tight, impedes water flow) 3 (Dry but shows evidence of water flow) Roughness 3 (Asperities clearly visible) 1 (Near-normal steps and ridges on fracture surface)

Borehole Geophysical Investigation All Fractures Open Fractures Transmissive Fractures Fracture Zones Faults Orientation Bias Terzaghi Correction Transmissive Fractures N325° / 77°NE N024° / 82°SW N255° / 89°NW 73% Steeply dipping (≥ 60°) 3% Shallow dipping (≤ 20°) Average 1D fracture density: 0.6 fractures/ft Average fracture spacing: 1.7 ft/ fracture Outcrop Fractures

Summary and Future Work Outcrop-correlated fracture traces Mostly steeply dipping fractures, striking from NW to NE Fracture spacing and density were similar between outcrop and borehole investigations Results improve the conceptual site model and can be used for future modeling (e.g. MODFLOW, DFN)
