The Farnworth Lake Floatplane Base is located in Canada in an isolated area about 10 km southwest of Churchill, Manitoba. Over many years of aviation storage and fueling, petroleum hydrocarbons contaminated the groundwater, with potential effects on a nearby lake. The remediation plan had to contend with the site's remote location far off the electrical grid in an area subject to harsh subarctic weather conditions. The site contractor designed a system powered by four wind-powered turbines to supply air for sparging to remediate BTEX contamination in the groundwater. The windmills selected for the site are typically used to aerate fish ponds or to fill livestock watering sloughs. The compressor delivers air through two lines ("header cells") installed through the groundwater plumes to increase pressure on the groundwater, thus driving out the more volatile contaminants. The turbine units are decommissioned and stored over the winter months. The windmill sparging system was installed in 2010 and has proven highly effective, with considerable cost savings compared to conventional sparge systems. http://www.federalcontaminatedsites.gc.ca/20C563C3-D699-4284-8780-CCDB27ADB495/1454%20Farnworth_FCSAP_Profile_En_02.pdf

In late 2013, a direct-fired thermal desorption (DTD) plant was mobilized from the United States to a former fire training area at RAAF Williams Base, Point Cook, Victoria, Australia. Following installation and commissioning of the plant and completion of successful proof of performance testing at a feed rate of 23 tonnes per hour in April 2014, full-scale treatment operations commenced. After optimization, the DTD operated at up to 30 tonnes per hour. Treatment activities ceased in February 2015, and the site has been rehabilitated and revegetated.

A pilot-scale injection of nanoscale zerovalent iron (NZVI) stabilized with carboxymethyl cellulose (CMC) was performed at an active field site contaminated with a range of chlorinated VOCs (CVOCs). CVOC concentrations and microbial populations were monitored at the site before and after NZVI injection. The remedial injection successfully reduced parent compound concentrations on site. A period of abiotic degradation was followed by a period of enhanced biotic degradation. Results suggest that the NZVI/CMC injection created conditions that stimulated the native populations of organohalide-respiring microorganisms. Dehalococcoides spp. abundance immediately following the NZVI/CMC injection increased by an order of magnitude throughout the treated area relative to pre-injection abundance. Distinctly higher CVOC degradation occurred over a 3-week evaluation period following NZVI/CMC injection when compared to control wells. Both abiotic and biotic degradation appear to have occurred following injection.

Comparative studies of the use of chlorine/ultraviolet (Cl₂/UV) and hydrogen peroxide/ ultraviolet (H₂O₂/UV) advanced oxidation processes (AOPs) to remove TCE from groundwater in a pump-and-treat application were conducted for the first time at the full-scale operational level at two water treatment facilities operated by Aerojet-Rocketdyne in Northern California. In these pilot studies, aqueous chlorine replaced hydrogen peroxide in the AOP treatment step, where the oxidant is exposed to UV light to produce highly reactive radical species that degrade groundwater contaminants. At the site where the natural pH of the water was 7.1, TCE was removed to a concentration <0.5 µg/L for nearly every chlorine dose-point tested, and pH adjustment enhanced the treatment process slightly. At the second site, which had a high natural pH of 7.7, TCE was not removed completely for any chlorine dose up to 5.7 mg/L, although TCE removal did increase when the chlorine dose increased between 0.9 and 3.6 mg/L. Residual TCE remaining in the water post-Cl₂/UV was readily removed using active carbon filtration, which is part of the facility's overall treatment train. The studies also verified that Cl₂/UV AOP did not interfere with the photolysis of N-nitrosodimethylamine or result in an effluent acutely toxic toward Ceriodaphnia dubia. Chemical costs associated with Cl₂/UV AOP were 25-50% of the costs associated with in-place H₂O₂/UV AOP treatment.

This report demonstrates different modeling approaches that use sediment temperatures to estimate the magnitude and direction of water flux across the groundwater-surface water transition zone. Following a review of analytical models based on steady-state or transient temperature solutions, case study applications of the modeling approaches are illustrated for two different field settings with quiescent and flowing surface water systems. For the quiescent system, two different steady-state models were used to evaluate temperature records from three depths to estimate groundwater seepage into a pond. For the flowing water system, two different transient models were applied to estimate water exchange across a granular cap placed atop sediments in a small river. http://nepis.epa.gov/Exe/ZyPURL.cgi?Dockey=P100MP4G.txt

This paper summarizes the state of the science regarding the biotransformation of dimethylarsinic acid (DMA[V]), a once-popular herbicide. The (V) suffix in DMA(V) denotes the +5 oxidation state of arsenic. The authors surveyed peer-reviewed and gray literature, input from experts in the field, and other pertinent sources to review the current understanding of biologically mediated transformation of DMA(V) and its metabolites. Given the challenges remaining in transitioning from lab studies to field applications, this paper provides summary guidance for implementing currently recommended remediation strategies for DMA(V) at contaminated sites. http://nepis.epa.gov/Adobe/PDF/P100MH3S.pdf

Urban soils within the Omaha Lead Superfund (OLS) site were contaminated with lead (Pb) from atmospheric deposition of particulate materials from lead smelting and recycling activities. The final ROD (May 2009) stated that any residential soil exceeding the preliminary remediation goal (a PRG of 400 mg Pb/kg soil) would be excavated, backfilled, and revegetated. The remedial action entailed excavating contaminated soil in the top 12 in; excavation could stop when the concentration of soil Pb was <400 mg/kg in the top 12 in or <1200 mg/kg at depths >1 ft. After removal of the contaminated soil, clean backfill was applied and a grass lawn was replanted. A depth of 12 in was based on the assumption that Pb-contaminated soil at depth greater than 1 ft would not represent a future risk, based on the principal that mixing and other factors encountered during normal excavation practices would not result in Pb surface concentrations above the PRG. Subsequently, Pb redistribution was investigated in remediated residential surface soils after typical homeowner earth-disturbing activities in the OLS site to determine whether soil mixing associated with normal homeowner excavation practices resulted in surface Pb concentrations above the PRG. Results from the 18 properties tested indicate that when Pb concentration was <1200 mg/kg in soil below 12 in depth, Pb surface soil concentration remained below 400 mg/kg. http://nepis.epa.gov/Adobe/PDF/P100MVEW.pdf

Microbial metabolism has the potential to alter the solubility of a broad range of priority radionuclides, including actinides and fission products, in uses such as the biostimulation of anaerobic microbial communities to remove redox-sensitive uranium U(VI) from contaminated groundwater. This paper offers a review the mechanisms of U bioreduction and phosphate biomineralization and their suitability to facilitate long-term precipitation of U from groundwater, with particular focus on in situ trials at DOE field sites. The review also discusses redox interactions of technetium, neptunium, plutonium, americium, iodine, strontium, and cesium.

Under anaerobic conditions, PCE and TCE can be degraded by a sequence of reductive dechlorination steps through the intermediate products cis-DCE and VC to ethene. This process is driven either by specific microorganisms or by reductive agents, such as nano- or microscale zero-valent iron particles (NZVI or MZVI, respectively). In a field test, a permeable reactive barrier was prepared by applying a mixture of NZVI and MZVI to a series of wells downstream from the source of contamination. Polymerase chain reaction (PCR) and real-time PCR analysis of microbial composition of groundwater up- and downstream of the barrier revealed that the recovery of microbial colonization in groundwater, including bacteria capable of degrading chlorinated ethenes, was strongly influenced by iron-driven dechlorination. http://avestia.com/ICEPR2014_Proceedings/papers/172.pdf

Kocur, Chris M.D., Ph.D. dissertation, University of Western Ontario, 300 pp, 2015

After verifying that nanoscale zero-valent iron (NZVI) synthesis methods can be safely scaled up and implemented at field scale, a successful demonstration was conducted of NZVI injection and mobility under constant head gravity injection into a utility corridor affected by chlorinated ethenes and ethanes in Sarnia, Ontario. NZVI detection and characterization using multiple methods proved that field mobility was reliably achieved. Additionally, long-term effects on the site's microbial communities were monitored to determine whether on-site organohalide-respiring species were enriched and CVOC degradation was sustained by the carboxymethyl cellulose polymer amendments that accompanied NZVI injection. Quantitative polymerase chain reaction was employed to target Dehalococcoides spp. (dhc) and vinyl chloride reductase genes (vcrA). The distinct zones where NZVI treatment was applied subsequently showed high abundance of dhc and vcrA. The methods used to target dhc and vcrA can serve as a template for future field investigations of NZVI mobility. http://ir.lib.uwo.ca/cgi/viewcontent.cgi?article=4602&context=etd

Chekli, Laura, Ph.D. thesis, University of Technology, Sydney, New South Wales, Australia. 309 pp, 2015

Developing novel methodologies to gain a better understanding of the behavior of engineered nanoparticles (ENPs) in the environment is crucial to assessing their potential risk. A multi-method approach that included flow field-flow fractionation, high-performance size-exclusion chromatography, and Fourier transform infrared spectroscopy was developed for thorough characterization of the behavior of iron oxide NPs (a surrogate for NZVI) under environmentally relevant conditions. The stability of iron oxide NPs coated with dissolved organic matter also was evaluated by assessing aggregation and disaggregation behavior over time. The following work was included in this research effort:

• Development of a novel method based on radiolabeling (Fe-59) to enable the detection and quantification of iron-based NPs in intact soil cores.
• Method improvement by coupling gamma counting and ICP-MS measurements to evaluate both the mobility of radiolabeled NPs and contaminant co-transport potential in soil.
• Development and demonstration of a simple method based on on-line light scattering measurement for characterizing NP aggregation behavior and aggregate structure in different natural waters.
• Combining the on-line light scattering method with off-line instruments, such as field-flow fractionation techniques, in a multi-method approach to gain complementary data on the particle size distribution of the samples.

This paper reviews current practice for both direct and indirect characterizations of nano zero-valent iron (NZVI) during groundwater remediation and explores prospects for improving these methods or refining the interpretation of the measurements. Results are presented based on laboratory batch and column studies of NZVI detection using chemical, electrochemical, and geophysical methods (e.g., using chemical redox probes for specific detection of NZVI). The potentiometric and voltammetric detections of iron nanoparticles using traditional stationary disc electrodes, rotating disc electrodes, and flow-through cell disc electrodes provide insight for interpreting ORP measurements, which are affected by solution chemistry conditions and the interactions between iron nanoparticles and the electrode surface. The geophysical methods used for characterizing ZVI during groundwater remediation are reviewed and assessed for application to NZVI detection.

NZVI reactivity is affected by both water chemistry and the properties of the NZVI particle used. The reactivity of three types of commercially available Nanofer particles (Nanoiron, s.r.o., Czech Republic)—uncoated Nanofer 25 particles; polyacrylic acid-coated Nanofer 25S (with the highest potential for transport within porous media); and air-stable Nanofer Star particles (very easy to handle)—were investigated to elucidate nanoparticle reactivity under a simulated field setting. Reaction rate was highest for the uncoated Nanofer 25 particles, followed by the coated Nanofer 25S and air-stable Nanofer Star particles. The Nanofer Star particles were the least reactive of all the Nanofer products tested. The reaction kinetics predicted by column experiments provided more realistic results than the reaction kinetics predicted by batch experiments.

This paper gives an overview of the challenges to nanoparticle detection and details possible methods for detecting, quantifying, and characterizing engineered nanoparticles (ENPs) in complex environmental matrices (e.g., water and soil/sediment), particularly against high background levels of ambient and naturally occurring nanoparticles. A description of the existing nanometrology tool kit is followed by a discussion of potential new measurement approaches that might overcome current limitations for ENP analysis in complex matrices. Estimates of ENP releases in life-cycle assessments suggest that the aqueous and soil/sediment environments will be the ultimate ENP reservoir. http://cfpub.epa.gov/si/si_public_file_download.cfm?p_download_id=520064

This operating procedure describes how to determine the nanomechanical properties, hardness, and Young's modulus at solid surfaces using atomic force microscopy (AFM). Briefly, an appropriate AFM cantilever is calibrated to determine its deflection sensitivity and spring constant; it then is used as both an imager and indenter at the surface of material of interest. The load applied by the cantilever is accurately controlled by knowledge of the deflection sensitivity. The maximum applied load is mediated by the cantilever spring constant. Following data collection, image and force curve analyses are completed to determine projected indent areas and to load/unload profiles, thus yielding materials properties that include the material hardness and the Young's modulus along with corresponding surface topography. http://www.dtic.mil/cgi-bin/GetTRDoc?AD=ADA616441

This report highlights selected projects that EPA's Engineering Technical Support Center (ETSC) supported throughout FY 2014. ETSC teams went into the field to spearhead projects at the cutting edge of remediation research in the areas of bioremediation and groundwater treatment, active sediment capping, in situ stabilization, and sustainable site cleanup. ETSC organized and reported significant developments in environmental engineering in several Engineering Issue papers as well as in peer-reviewed journal publications. ETSC also began newer initiatives that focus on integrating sustainability into communities and land-use plans. While ETSC's principal mission of bolstering technical expertise for site-specific remediation at contaminated sites remains a central focus, its teams are reaching out to support other efforts in prevention, thereby reducing EPA's future burden from legacy sites. http://nepis.epa.gov/Exe/ZyPURL.cgi?Dockey=P100MVJ3.TXT
