Deliverables: • Quarterly progress reports (in letter format) for 2021 biennium (four [4]total reports) Schedule: • Activities will be conducted throughout the life of the change order associated with this scope of work. • Progress reports will be issued quarterly. Task 26—Off-Property High-Resolution Site Characterization Purpose: Evaluate and determine the potential sources, depth, and lateral extent of the halogenated volatile organic compound (HVOC) dissolved-phase plume inferred upgradient to the west-northwest of the West Nob Hill Boulevard site (Site) and its pathway to the Site. Evaluate its transport and storage zones and identify pathways for potential mobility. 1 7 MFA Project No.0818.02.01 March 12,2021 Scope: MFA will subcontract Columbia Technologies to perform HRSC of the HVOC-impacted dissolved-phase plume by using the combined membrane interface probe and hydraulic profiling tool subsurface assessment technologies. Assessment activities will include: • Assess the suspected sources of HVOC-impacted groundwater using multiple high-resolution vertical aquifer profiles. • Assess the possible pathways from the suspected sources to the Site by completing two or more high-resolution transects across the direction of groundwater flow. • Evaluate the strata and type of soil and soil permeability in which the source material is resident within the groundwater regime. • Evaluate the vertical extent of the impacted groundwater, as much as practicable. • Identify probable storage and transport zones. • Identify pathways for the potential mobility of HVOCs. • Evaluate the hydrogeologic conditions of the unconfined and/or confined aquifer and the relationship of the air-water interfaces to the residual HVOC-impacted soils/groundwater. • Confirm the findings of the direct HRSC imaging surveys by measuring the mass of the HVOC contamination in groundwater at selected depths and locations via collecting targeted discrete groundwater samples. • Measure the mass of residual HVOC contamination present in the soil matrix within the saturated zone via targeted, discrete soil sampling. • Provide real-time data, information, and updates to Ecology and the City through Columbia Technologies' Smart Data Solutions. • Update the conceptual site model. Schedule: • Fieldwork is proposed for the second quarter of 2021. The actual schedule is dependent upon the review and approval from Ecology and the City of the proposed scope of work • A draft report with investigation findings will be issued within eight to 12 weeks of receipt of final laboratory analytical results. Assumptions: • All proposed subsurface investigation locations (i.e., borings) will be advanced in the City's right- of-way (ROW) unless access to private properties is needed and granted by property owners. Refer to the attached Figure. • The City will assist with coordinating approval of the ROW request. • Two to three transects of temporary borings will be advanced downgradient to the east-southeast of the suspected sources of the HVOC-impacted dissolved-phase plume to assess the hydrostratigraphy and soil permeability, as well as delineate the HVOC-impacted dissolved-phase contamination distribution upgradient of the Site. Findings from the initial HRSC borings will inform the locations and depths of subsequent borings for assessment of the HVOC-impacted groundwater. • Air knife/vacuum will be conducted at each proposed boring prior to drilling and HRSC activities due to the anticipated presence of underground utilities (municipal water lines and sanitary sewer lines) along the streets and ROW(West Nob Hill Boulevard, South 24th Avenue, and South 28th Avenue). It is anticipated that air knifing will advance to 5 feet below ground surface. 2 8 MFA Project No.0818.02.01 March 12,2021 • Traffic control will be present throughout the off-property HRSC fieldwork. • An estimate of 10 borings will be advanced to targeted depths of 25 to 40 feet below ground surface via direct push drilling methodology. It is anticipated that the field phase of this assessment may take up to six days. • Laboratory analyses of volatile organic compounds (VOCs) for soil and groundwater samples will be analyzed on a 48-to 72-hour turnaround time (TAT) to provide supplemental data for field assessments of the HVOC-impacted dissolved-phase plume. • Draft revisions will be issued in electronic format; final revisions will be issued in electronic and hard copy format. Deliverables: • Off-property HRSC assessment findings and report (in report format) Task 27—Indoor Air and Ambient Air Quality Assessment Purpose: Evaluate whether indoor air quality of existing buildings adjacent to the former Tiger Oil facility, including the Xochimilco Mexican Restaurant, Barber HQ, and 1UP Games, has been adversely impacted by the HVOC-impacted groundwater at the Site.
