Kentucky Division of Waste Management Annual Report, FY 2013, 22-24, 2013

At the Paducah Gaseous Diffusion Plant (PGDP) Superfund site, the C-400 Cleaning Building is the source of much of the TCE that now contaminates the site groundwater. In July 2013, the second phase of an electrical resistance heating (ERH) remedy was initiated to address part of an estimated 75,000 gallons of TCE in the subsurface. The ERH system features 52 borings, each with three 10-ft-long metal electrodes that heat soil to more than 194°F to evaporate the TCE so that it can be removed from the soil via vacuum extraction. The vapors are treated using carbon filtration and air stripping. Once this phase of the C-400 remedy is complete, a final phase will be initiated for TCE present within the aquifer at greater depths. http://waste.ky.gov/Annual%20Reports/DWM%20Annual%20Report%20for%202013.pdf
Heat also will be applied during steam-enhanced deep soil mixing to remediate TCE at the PGDP Oil Landfarm, a dumping ground for waste oils. See the Treatability Study Work Plan for Steam Injection at http://www.paducaheic.com/media/114083/ENV1.A-00516-PDI05.pdf.

CleanUp 2013: 5th International Contaminated Site Remediation Conference, 15-18 September 2013, Melbourne, Victoria. Presentation C44, 24 slides, 2013

A plume of dissolved-phase PCE migrated from the drycleaner and affected five other properties. Cleanup goals were determined for the chlorinated solvent groundwater concentrations: 5 mg/L by 26 May 2013 and 0.5 mg/L by 26 May 2016. Following a successful pilot test, the in situ bioremediation system design incorporated 20 groundwater recirculation loops installed across the affected sites, covering an area of almost one hectare. Groundwater was extracted downgradient, amended with sodium lactate, and reinjected upgradient. After 10 months of operation, groundwater contaminant concentrations fell to the 0.5 mg/L (2016) goal in 40% of the area.

Beale Air Force Base: Environmental Cleanup Program, Issue 59, 1-5, Oct 2013

For control and management of free-phase TCE DNAPL at Site 17, Beale Air Force Base, a slurry wall was keyed into siltstone bedrock ~35 ft bgs to isolate the DNAPL source area, from which a dissolved-phase plume extends about 4,000 ft downgradient. As part of this interim remedy, a phytoremediation system of 400 cottonwood, willow, and holly trees was installed within the slurry wall in 2001. The design called for elimination of pump and treat when the trees matured; however, the tree plantation so far has not reduced the need for pumping to maintain an inward hydraulic gradient. To control a secondary source of DNAPL discovered adjacent to and outside the slurry wall in 2005, a combined slurry wall/ZVI PRB was designed and built in 2006. A final remedy being evaluated includes 1) injecting EHC-L to treat DNAPL residuals in source areas; 2) removing a 200-ft downgradient section of the primary slurry wall and replacing it with another ZVI/PRB; and decommissioning the existing pump-and-treat system. http://www.beale.af.mil/shared/media/document/AFD-131104-131.pdf

The source area wells had cis-1,2-DCE and VC concentrations of 47,000 and 8,000 µg/L, respectively, from undocumented buried drums. Groundwater contamination was addressed with in situ chemical reduction (ISCR) using the DARAMEND® ISCR technology (a carbon source and zero-valent iron particles). The groundwater is relatively stagnant, anaerobic, and mildly reducing, with an estimated velocity of about 0.0023 ft/day. Site soils consist of silty clay overlying bedrock (~16 ft bgs). After excavation to remove the drums, DARAMEND was added at an application rate of 1 wt% to native soil mass in the soils below the water table. Upon completion of the excavation, mixing, and backfill operations, the contractor capped the former drum area. Remediation to groundwater quality standards was reported in all the wells except the source area monitoring well, and additional enhanced bioremediation will target the source area. http://ipec.utulsa.edu/Conf2013/Manuscripts_pdfs/ISCR_Haryani.pdf

CleanUp 2013: 5th International Contaminated Site Remediation Conference, 15-18 September 2013, Melbourne, Victoria. Presentation E24, 25 slides, 2013

Horizontal remediation well technologies were used in conjunction with in situ chemical oxidation (ISCO) to remedy a PCE-contaminated drycleaner site in Parole, Maryland. The cleanup took place on an active construction site. Site soils were silty sand. The contaminated groundwater zone was 25-55 feet bgs, and groundwater flow was 0.2-0.4 ft/day. Ten horizontal wells of a total of 3,875 ft at two soil depths were installed. The first of two injections delivered 340,000 gallons of permanganate solution, and the second delivered 1,032,333 gallons of solution. The ISCO treatment reduced PCE groundwater concentrations in the source area from 13,000 ppb to 400 ppb. Downgradient, PCE concentrations declined from 8,000 ppb to a maximum of 1,840 ppb, though most wells were nondetect. The length of screen in the horizontal wells permitted faster and more effective delivery of the ISCO treatment. The large permanganate zone of influence permitted a more complete reaction with the soil and groundwater PCE such that rebound did not occur and the site was closed. http://www.cleanupconference.com/presentations/Advanced%20remediation%20technologies.zip

ESTCP Project ER-200541, 384 pp, Nov 2013

The project successfully demonstrated the feasibility of a membrane biofilm reactor (MBfR) to destroy perchlorate and nitrate in groundwater via anoxic autotrophic biodegradation and produce potable water at the pilot scale. The investigators also evaluated process control parameters to optimize performance and estimated full-scale technology costs. The unit consisted of two 575-gallon MBfR vessels in a two-stage lead/lag configuration, with each tank containing seven polypropylene-fiber membrane modules—a total membrane surface area of 2,000 m². The MBfR was colonized with indigenous perchlorate- and nitrate-reducing bacteria within about one month. In the effluent of the lag reactor during steady state, perchlorate declined by ~94% to 9.2±2.3 µg/L and total nitrogen (the sum of nitrate and nitrite) fell by ~99% to an average of 0.12±0.07 mg-N/L. http://www.serdp-estcp.org/content/download/23078/235147/file/ER-200541-FR.pdf

A trial of technologies to evaluate the efficacy of bioremediation and in situ chemical reduction at remediating TCE-contaminated groundwater within a fractured basalt environment was undertaken in July 2011. A custom blend of organic carbon and zero-valent iron (ZVI), a propriety blend of controlled-release organic carbon plus fine-grained particles of ZVI (EHC-F®), and a sodium lactate-based organic amendment were injected into separate well arrays using a helical screw direct-displacement pump and pneumatic packer to transfer the amendment to the treatment zone. Periodically, the injection wells were gravity-fed with organic-based amendments, and three of the wells were bioaugmented with a Dehalococcoides culture 10 months after the first injection. Mass reduction and complete reductive dechlorination with resulting molar reduction was evident for some of the trialled compounds, and monitoring for long-term trends continues. A full-scale injection well network of ~90 wells was designed, installed, and injected with EHC® in late 2012.

Phosphate amendments have been studied as a means to mitigate risks from exposure to Pb in soil by promoting the formation of highly insoluble Pb species, such as pyromorphite. The formation of insoluble Pb species thereby reduces the risk of Pb leaching through soils into drinking waters and absorption by soil biota, and likely makes it less bioavailable during physiological transport in the human gastrointestinal tract following incidental ingestion. This paper provides a detailed description of phosphate chemistry and the goal of converting Pb into pyromorphite.

ESTCP Project ER-200517 had the following technical objectives:

1. Provide validation that the relationships between soil properties and in vitro bioaccessibility methods can serve as a screening tool for estimating in vivo toxic metal bioavailability in DoD soils.
2. Provide a scientifically and technically sound method for estimating human and ecological risk associated with metal contaminated soils in place of or as justification for more detailed, site-specific bioavailability (e.g., animal dosing) studies.
3. Promote the use of in vitro methods in human health and ecological risk assessments.

Phytoremediation can be integrated into the transformation of urban post-industrial areas, while improving public space. Buiksloterham, an industrial area contaminated with heavy metals (e.g., zinc) in Amsterdam, serves as case study. A regression-model estimate of the time needed to remediate the site using Alpine Pennycress (Thlaspi caerulescens) revealed a conflict in time between remediation and urban development. A research-by-design experiment showed how to overcome this conflict by dealing with contaminated soil innovatively while emphasizing spatial and aesthetic qualities of the phytoremediation plant species. The resulting landscape framework integrated phytoremediation with biomass production, giving new ecological and economic value to Buiksloterham.

Field experiments were conducted to assess the potential for anaerobic biostimulation to enhance BTEX biodegradation under fermentative methanogenic conditions in groundwater containing a biodiesel blend (B20, 20% v/v biodiesel and 80% v/v diesel). One 100-L B20 release was biostimulated with ammonium acetate added weekly through injection wells near the source zone over 15 months. The other release remained unamended to serve as a control. BTEX removal began within 8 months in the biostimulated source zone, whereas BTEX concentrations were still increasing in the control two years after the release due to source dissolution. Biostimulation fortuitously enhanced the growth of putative anaerobic BTEX degraders and associated microorganisms that consume acetate and H² and enhance the thermodynamic feasibility of BTEX fermentation. Field results indicate that anaerobic-methanogenic biostimulation can enhance source zone bioremediation of groundwater aquifers affected by biodiesel blends. http://alvarez.blogs.rice.edu/files/2013/05/156.pdf

The primary risk driver at DoD sites with Cr(VI) in the soil is hand-to-mouth ingestion of contaminated soil by children. Investigators evaluated the impact of soil geochemical and physical properties on the sorption and bioaccessibility of Cr(VI) in 35 soils. A-horizon soils typically sorbed significantly more Cr(VI) relative to B-horizon soils. Multiple linear regression analysis suggested that the bioaccessibility of Cr(VI) and its reduced counterpart Cr(III) decreased with increasing soil TOC and increasing soil pH. The results of this study help to define what soil types have the greatest risk associated with Cr(VI) exposure.

Varying compositions (15-30% by weight) of coarse and ground waste drywall were added to manure and biosolids during composting. Six composts were applied at four rates (0, 50, 100, 200 Mg/ha) to three reclamation soils (agricultural, urban clean fill, and oil sands tailings). Response to composts was assessed with three plant species: barley, slender wheatgrass, and Rocky Mountain fescue. Although no negative effects were observed after drywall addition, only low-quality tailings sand showed improved plant response following addition of 30% coarse drywall. Grinding drywall did not improve plant performance significantly; hence, use of coarse drywall would eliminate the need for specialized equipment and resources.

Lead (Pb) data from environmental soil sampling on 31 residential properties adjacent to six municipal water towers historically coated in Pb-based paint were derived from 498 core samples. Analysis indicated that surface samples alone were insufficient to classify a property as "lead safe." Post-remediation Pb-soil concentrations suggest the extent of Pb contamination might have been deeper than initially determined. Recommendations for improvement include specific modifications to Pb-soil sampling regulations reflective of lowered CDC reference blood Pb value for children 1 to 5 years old (5 µg/dL). http://www.ecori.org/storage/WaterTowerLeadStudy.pdf

River Mile 10.9 Removal Action Final Design Report, Lower Passaic River Study Area. U.S. Army Corps of Engineers, Appendix H: 12 pp, 2013

In August 2012, two vendors of sediment washing technologies (BioGenesis and Pear Technology) performed bench-scale treatability tests using bulk sediment samples collected from the Lower Passaic River study area river-mile 10.9. This report summarizes results for key site constituents. The sediment washing bench-scale tests did not achieve the degree of removal required to meet residential soil cleanup standards or provide cost-effective contaminant reductions for disposal at landfills (RCRA Subtitle D versus Subtitle C) for dioxins/furans, PCBs, and PAHs in the RM 10.9 removal area sediments; therefore, the cooperating parties group will not conduct sediment washing at pilot scale. http://passaic.sharepointspace.com/Public%20Documents/20130731%20RM%2010%209%20Final%20Design%20App%20H%20Bench-Scale%20Rep.pdf

A field study was conducted to determine the optimal planting mode for pakchoi (Brassica rapa chinensis, i.e., bok choy, or Chinese cabbage) in Cd-contaminated soil to reduce accumulation of Cd in the edible parts while maintaining yields. Four additives (red mud, silicon calcium fertilizer, spodium, and calcium magnesium phosphate), two foliar fertilizers (Ca and Zn), and two varieties of bok choy were used in the study. Red mud provided optimal results in reducing Cd accumulation in the edible parts as well as the available Cd concentration in the contaminated soil while simultaneously increasing plant biomass in both bok choy varieties. http://www.aepi.org.cn/Upload/Files/NewsAttatches/2647/additive.-.201353155343.pdf

Scientists evaluated the diversity of Dehalococcoides sp. and three of their reductive dehalogenase (RDase) genes in groundwater, microcosms set up with contaminated groundwater from the same field site, and water from a constructed wetland. The investigators found that although the Dehalococcoides 16S rRNA gene sequences retrieved from the investigated systems were identical, the RDase gene diversity varied among the systems according to the spectrum of the chlorinated ethenes present.

PCBs can emanate from PCB-containing products in building environments in both vapor and particulate form. Secondary sources of PCBs, such as caulk or light ballasts, can contribute to the overall exposures. Building owners and occupants may be unaware of the existence of these materials and their potential hazards. Due to a lack of data on potential exposures from sources in the built environment, it is not clear what the risk from these PCB-containing building materials is when compared to other PCB exposures (e.g., diet). This white paper 1) provides an overview of currently available information pertaining to PCBs in construction materials; 2) evaluates the exposure potential for building occupants and maintenance and construction personnel; and 3) identifies gaps in the current knowledge concerning the risk to public health from PCBs in building materials. http://www.aiha.org/government-affairs/WhitePapers/PCBs%20in%20Construction%20White%20Paper%20FINAL%209-26-13.pdf

This document provides an overview of potential exposure to lead (Pb) while gardening and consuming home-grown produce. Based on currently available information, best management practices (BMPs) are suggested for gardening in Pb-contaminated areas to reduce Pb exposure in contaminated soil. The BMPs are based on a review of the literature and best professional judgment to identify appropriate risk-mitigating actions associated with the varying ranges of soil Pb concentrations in produce gardens. Key data gaps and uncertainties are noted.

The Superfund remedial program has sustained substantial budget reductions over the past two fiscal years. This action plan, the result of a remedial program review, identifies short- and long-term measures and activities EPA will undertake to maintain an effective remedial cleanup program under budgetary constraints. The plan is divided into two major sections: Cleanup Process and Program Management Actions. The cleanup processes sections discuss adaptive management (an iterative process that allows modifications to remedial approaches based on newly acquired information) and the assessment, study, design and construction phases of the remedial process. The program management activities outline actions to use internal Agency resources, such as contracts (acquisitions), budget, in-house expertise, and information technology, more efficiently. http://www.epa.gov/superfund/cleanup/pdfs/Final_SPR_Action_Plan-11_26_2013_(2).pdf

This compilation contains peer-reviewed papers presented at the 2013 ASTM symposium in Jacksonville, Florida, which addressed methods for identifying and managing vapor intrusion risks. Prevailing sampling programs may fail to characterize vapor intrusion problems fully due to extreme spatial and temporal variability of VOCs and methane at contaminated sites. Ideally, where vapor intrusion risks are dynamic, vapor intrusion investigations also will be dynamic, and the investigations will involve continuous monitoring rather than one or two discrete monitoring events. The papers in this volume summarize state-of-the-art thinking on vapor intrusion by an international team of authors.

U.S. EPA, Brownfields Newsroom Announcements, 2013

On December 30, 2013, EPA published a final rule amending the All Appropriate Inquiries (AAI) Rule to reference ASTM International's E1527-13, "Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process" and allow for its use to comply with the AAI Rule (78 FR 79319). ASTM (www.astm.org) regularly reviews and revises its standards, and it recently revised the 2005 version of E1527. Among other changes, the E1527 2013 version states that Phase I environmental site assessments must include, within the scope of the investigation, an assessment of the real or potential occurrence of vapor migration and vapor releases on, at, in, or to the subject property. Other than recognizing the new ASTM E1527-13 standard as compliant with the AAI rule, there are no changes to the final rule setting standards and practices for conducting AAI at 40 CFR Part 312. See the Federal Register notice, "Amendment to Standards and Practices for All Appropriate Inquiries under CERCLA" at https://www.federalregister.gov/articles/2013/12/30/2013-31112/amendment-to-standards-and-practices-for-all-appropriate-inquiries-under-cercla.
