Exploring New Frontiers in Reclamation: 2014 National Meeting of the American Society of Mining and Reclamation, Oklahoma City, OK, June 14-20, 2014. Book of Abstracts, p 33, 2014
In 1997, the Jennings vertical flow pond (VFP) passive treatment system was installed at the Jennings Environmental Education Center in Butler County, Pennsylvania. The hydraulic design life of the media was estimated at 7-10 years, with exhaustion of the acid mine drainage (AMD) neutralizing capacity at ~14 years. Occasional maintenance activities, such as stirring the treatment media, is believed to have extended media life, but after almost 15 years of near-continuous operation, the treatment media of the VFP at Jennings experienced a significant loss of permeability. In 2012, media from the VFP was removed and encapsulated in Harsco's Mineral CSA, an alkaline material byproduct produced during recovery of metals from steel slag. Next, a new underdrain, bedding stone, and treatment media (spent mushroom compost, high-calcium limestone, and single-shredded woodchips) were installed. Post-rehabilitation water quality monitoring indicates that the system is functioning well. Additional information: http://www.paenvironmentdigest.com/newsletter/default.asp?NewsletterArti
SMART 2013: Smart Methods in Advanced Remediation Technologies, Calgary, Canada. 32 slides, 2013
This presentation provides an overview of how environmental fracturing technologies can overcome the limitations of in situ remediation in low-permeability lithologies. Two case studies showcase the integrated and synergistic use of fracture enhancement techniques for attaining sustainable and cost-effective remediation: (1) gasoline in shallow clays and (2) TCE in deep bedrock. Physical, biological, and chemical (reductive and oxidative) treatment technologies are addressed in the context of both subsurface extraction and delivery techniques to optimize contact with contaminants for their conversion to innocuous and natural end products.

The selected cleanup action for the Bee-Jay Scales site comprises shallow source-zone soil excavation, in situ bioremediation injection wells/borings (for delivery of a sodium acetate solution or calcium acetate to address nitrate and pesticide contamination in groundwater (e.g., 1,2-dichloropropane) and soil (e.g., 1,2,4-trimethylbenzene)), institutional controls, natural attenuation, and vertical permeable reactive barrier(s) or other Ecology-approved treatment method for the off-property groundwater plume attributable to the site. A biologically operated PRB consisting of sand mixed with phosphate and some type of organic material (mulch, compost, wood chips) would be appropriate for this site. A bench-scale study and field pilot (introduction of sodium acetate into four injection wells on the property) were conducted as part of the Phase II remedial investigation to guide potential nitrate and herbicide remediation activities. The treatability study determined the most effective treatment was denitrification using acetate as an electron donor. The pilot study demonstrated that injection of acetate was successful in remediating nitrate and nitrite concentrations to below detectable limits in groundwater within a 10-ft radius of the affected well for the duration of the monitoring period and also reducing concentrations of those constituents in saturated soils. https://fortress.wa.gov/ecy/gsp/DocViewer.ashx?did=10578

The Smalley-Piper site, ~9 acres in size, is located in Collierville, Shelby County, Tennessee. Among various industrial activities conducted at the site from the 1950s to 1980s, the manufacture of magnesium battery casings utilizing caustic soda, acetic acid, chromium acid, and water led to the contamination of soil, surface water pathways, and groundwater in the Memphis aquifer in the site vicinity. All on-site operations at the facility ceased in 2007. The amended Superfund State Contract (SSC) addresses the previously performed soil remedy of excavation and ex situ stabilization/solidification and adds a soil flushing component. The amended SSC has a total current estimated cost of $7,781,970, with the State's 10% match being $778,197. The original SSC addressing soil remedial action was performed at a cost of $1,982,915. The intent of the in situ flushing remedy is to reduce remaining Cr(VI) subsurface soil concentrations that might continue to leach into groundwater. Water will be extracted by on-site recovery wells; treated by chemical reduction, precipitation, and ion exchange treatment modules; and then re-injected into the former source area via an infiltration gallery. The system is expected to operate for one year, with July 31, 2015, the goal for remedy completion. http://www.tn.gov/environment//docs/dor/annual_leg_report_fy_2012_2013.p
An in situ thermal treatment remedy in the source area removed the majority of contaminant mass and reduced TCE concentrations in soil and groundwater near the source area accordingly; however, TCE concentrations in confirmation soil samples are nearly two orders of magnitude higher than the site-specific soil cleanup standard for TCE, which suggests that contamination remains in vadose zone soil. The August 2011 TCE concentration of 78 µg/L in monitoring well RW-05 (based on the most recent round of sampling at that location available to the optimization review team), further suggests the potential that a source of groundwater contamination remains in this area. The reviewers provided recommendations to improve remedy effectiveness and accelerate site closure. http://clu-in.org/Optimization/reportsDetail.cfm?opEvalID=128
Demonstrations / Feasibility Studies
ESTCP Project ER-200705, 416 pp, 2013
This project demonstrated a generalized data-driven paradigm for the assessment of source zone natural attenuation (SZNA) at chlorinated aliphatic hydrocarbon (CAH) cleanup sites. The method uses multiple lines of evidence and macroscopic mass balances, leading to confirmation of SZNA and quantification of the total mass loss rate resulting from degradation, dissolved-phase transport, and volatilization. Application of the method was demonstrated at three field sites, with multiple events per site spread out over about three years. The mass loss rates were relatively consistent over time for each site, but varied from site to site, ranging between about 1 to 10 kg/y at two sites and as high as about 600 kg/y at the third site. http://www.estcp.com/content/download/27662/274807/file/ER-200705-FR.pdf
West Virginia Mine Drainage Task Force Symposium, Morgantown, West Virginia, March 25-26, 2014. Abstract and 41 slides, 2014
A patented carbonization process is used to convert raw reed sedge peat into APTsorb™, a granular, hardened ion-exchange material with high affinity for trace metals, particularly lead. An APTsorb™ pilot test was initiated at a base metal mine in North America in October 2013. The pilot was designed to model both an active (pressurized tank) and a passive (biocell) treatment system approach. A pressurized sand filter was installed before both systems. Input mine water had a pH >7 and contained about 1,500 µg/L Pb, 100 µg/L Zn, and 1.5 µg/L Cd. The sand filter essentially removed all suspended metals, but removal decreased as the pressure drop over the filter increased. Both pilot systems removed >99% of the Pb and reduced all metals to below permit values. In a model of full-scale treatment for a mine discharge of 8,000 gpm, capital costs were ~$5 million, about a factor of three less than a standard chemical treatment plot.

West Virginia Mine Drainage Task Force Symposium, Morgantown, West Virginia, March 25-26, 2014. Abstract and 28 slides, 2014
The subject full-scale sulfate-reducing bioreactor (SRBR) had a volume of ~1,300 m3 and contained a mixture of wood chips, sawdust, hay, and manure. The influent flow rate varied from ~0.4 to 30 L/min, and influent iron and zinc concentrations varied by more than an order of magnitude. The passive, full-scale system was installed in 2009. The accumulation of aluminum and iron precipitates at the inlet piping and distribution system initially affected SRBR performance such that the influent zone was modified in the first year. During three additional years of operation, aluminum and iron minerals continued to precipitate in the distribution piping, albeit at a lesser rate. From this investigation of full-scale SRBR operation, the necessity of pre- and post-treatment for more efficient treatment of mine effluent is recommended.

Groundwater monitoring at the Idaho Pole Company (Bozeman, Montana) indicates that pentachlorophenol (PCP) concentrations are declining at a rate likely to require several decades or more to achieve cleanup standards. Site conditions are favorable for using the current pump-and-treat system to deliver amendments to the aquifer that could accelerate PCP degradation. Following a detailed technology evaluation and screening, two aerobic degradation technologies involving injection of amended water (hydrogen peroxide solution and ex situ aerated) were retained for pilot testing. This work plan details the methods proposed for evaluating the effectiveness of the two technologies for enhancing aerobic degradation of PCP in the Idaho Pole groundwater. The evaluation will be conducted by performing a pilot study over a period of ~4 months just upgradient of an area where PCP concentrations recently have been observed up to 2,000 ppb. http://www2.epa.gov/region8/idaho-pole-co-pilot-study-work-plan-aerobic-
ESTCP Project ER-201030, 191 pp, 2014
An enzymatic bioassay for determining the amount of perchlorate in an aqueous sample was developed initially under SERDP Project ER-1530. Under ESTCP Project ER-201030, the method was examined further to (1) compare benchtop bioassay results from testing in the primary investigator's lab to results from a reference analytical method performed by a commercial lab, and (2) compare results with a benchtop bioassay kit format tested by site field personnel to the site's routine perchlorate detection method (results varied). Because performance of the bioassay was insufficient to warrant proceeding with its field testing in a kit format, the focus of activities shifted to attempting to identify factors that interfere with the benchtop bioassay in order to determine whether operations and performance could be improved. http://www.estcp.com/content/download/27663/274817/file/Final%20Report%2
This project investigated less invasive methods for the assessment of soil microbial activity under in situ conditions using the well-established BACTRAP® in situ microcosm system adapted to direct-push technology. A field test revealed that the DP-BACTRAP probe is applicable to use in an aquifer and compares better to in situ soil conditions than conventional use of the BACTRAP system. In the laboratory, the DP-BACTRAP probe established hydraulic equilibration with the surrounding soil under vadose zone conditions within 2-3 days, thereby facilitating microbial colonization of the supplied activated carbon. Hexadecane was used as a model compound for crude oil contamination at a field site in a comparison experiment between BACTRAPs and other commonly used soil incubation microcosms. Results indicated similar performance, thus demonstrating the general applicability of the approach for this type of contaminant under vadose zone conditions. https://www.ufz.de/export/data/global/55998_ufz-diss_07-2013.pdf

The Rejuvenate project (http://projects.swedgeo.se/r2/
Plant growth-promoting rhizobacteria (PGPR)-enhanced phytoremediation systems (PEPS) have been deployed at over 35 sites in Canada for full-scale removal of petroleum hydrocarbons (PHCs) and salt from soil. PEPS provide large amounts of root biomass in contaminated soil, which promotes growth of rhizosphere microorganisms. The root and rhizosphere biomass allows rapid partitioning of contaminants out of the soil and their subsequent uptake and/or metabolism by microbes and plants. These processes result in degradation of PHCs in soil and large amounts of biomass for sequestration of salt into plant foliage. PEPS deployment has achieved ~35% remediation per year of PHC from soil (mostly F2, F3, and F4). Both grasses and cereals take up sufficient amounts of salt to result in 10-20% remediation per year. PEPS implementation has demonstrated that it is very effective for treatment of a wide variety of PHC- and salt-impacted sites, including sites with co-contaminants.

This special series of six Open Access papers was generated from the SETAC Technical Workshop, "Guidance on Passive Sampling Methods to Improve Management of Contaminated Sediments," held November 2012 in Costa Mesa, California. Forty-five experts&emdash;passive sampling method (PSM) developers, users, and decision-makers from academia, government, and industry&emdash;convened to review the state of science to gain consensus on PSM applications in assessing management actions on contaminated sediments. Recent advances in PSMs offer an improvement in risk-based decision-making because bioavailability of sediment contaminants can be directly quantified. The following topics are covered:
- Building consensus to improve decision making (pp 163-166).
- State of the science for organic contaminants (pp 167-178).
- State of the science for metals (pp 179-196).
- Scientific rationale supporting use of freely dissolved concentrations (pp 197-209).
- Practical guidance for selection, calibration, and implementation (pp 210-223).
- Risk assessment and management (pp 224-236).

Passive samplers were used to determine water concentrations of persistent organic pollutants (POPs) in the surface sediments and near-bottom water of a marine Superfund site on the Palos Verdes Shelf, California. Measured concentrations in the porewater and water column at four stations were used to calculate the flux of POPs, including DDE, DDD, DDMU, and selected PCB congeners, across the sediment-water interface due to molecular diffusion. Three passive sampling materials were compared: polyethylene (PE) strips, polyoxymethylene (POM) strips, and solid-phase microextraction (SPME) fibers. Performance reference compounds (PRCs) were used with PE and POM to correct for incomplete equilibration, and the resulting POP concentrations determined by each material agreed within one order of magnitude. SPME fibers, without PRC corrections, produced values that were generally much lower (one to two orders of magnitude) than those measured using PE and POM. In addition, diffusive fluxes measured within the Superfund site using PE strips at stations outside a pilot remedial sand cap area were similar to those measured at a station inside the capped area: 240 to 260 ng/cm2/y for p,p'-DDE. This work demonstrates the utility of passive samplers for making in situ flux measurements at contaminated sediment sites.
This special series of six Open Access papers documents the results of group discussions at the workshop, "Ecological Soil Levels: Next Steps in the Development of Metal Clean-Up Values," held September 17-21, 2012, in Sundance, Utah.

- Deriving site-specific clean-up criteria to protect ecological receptors (plants and soil invertebrates) exposed to metal or metalloid soil contaminants via the direct contact exposure pathway (pp 346-357).
- Furthering the derivation of predictive wildlife toxicity reference values for use in soil cleanup decisions (pp 358-371).
- Recommendations to improve wildlife exposure estimation for development of soil screening and cleanup values (pp 372-387).
- Deriving site-specific soil clean-up values for metals and metalloids: Rationale for including protection of soil microbial processes (pp 388-400).
- Regulatory considerations for the potential development and application of metal cleanup values (pp 401-414).
To ensure that brownfield cleanups remain effective despite climate changes EPA has added a new term and condition to its cooperative agreements, starting with the FY13 Cleanup and Revolving Loan Fund (RLF) Grants, that requires recipients to "evaluate the resilience of the remedial options in light of reasonably foreseeable changing climate conditions (e.g., sea level rise, increased frequency and intensity of flooding, and/or extreme weather events, etc.)." EPA has created a brownfield cleanup alternatives checklist to help Cleanup and RLF grant recipients meet this new term and condition. http://www.epa.gov/brownfields/sustain_plts/factsheets/EPA_OBLR_Climate_
The capacity of wetlands to retain, accumulate, and degrade pollutants in both urban and rural environments has been recognized for decades. The WETPOL symposium, established in 2005, has become a reference forum for the fundamental knowledge on pollutant dynamics and control inside wetland systems, with an emphasis on wetlands constructed specifically to control or mitigate the impact of pollutants on the environment. Every two years, leading experts meet and present their research activities and experiences and discuss new concepts and new technologies. The extended abstracts from WETPOL 2013 are posted in 10 separate PDF chapters at http://www.emn.fr/z-ener/wetpol2013/index.php?page=book-of-abstracts

This report follows up on the findings of the Superfund Site Assessment Program: Benefits beyond NLP Listing reports. The previous reports collected and reported the numbers of non-NPL outcomes on a national scale, however, their scope did not include investigating how these beneficial outcomes occur. This analysis reports how states (1) leverage CERCLA site assessment work products to achieve cleanup outcomes, both NPL and non-NPL; (2) use their site assessment cooperative agreement funding; (3) employ efficiencies and best practices to improve the site assessment program; and (4) track non-NPL beneficial outcomes of sites evaluated with their site assessment cooperative agreement funding. http://www.astswmo.org/Files/Policies_and_Publications/CERCLA_and_Brownf

Each demolition or refurbishment measure at a brownfield site causes emissions (e.g., gases, liquids, solids, noise, heat, vibration, light) that affect people, technical equipment and infrastructure directly related to the construction site and the surrounding area. This report describes typical emissions resulting from brownfield site redevelopment, emission prediction methods, and measures for minimization. http://www.andrea-kubitz.de/timbre/tl_files/timbre/Intern/4%20Work%20Pac
Many Navy installations receive requests to evaluate lead-based paint at cleanup sites. Each RPM is encouraged to discuss site-specific conditions with the respective Facilities Engineering Command ER manager to determine if circumstances allow for Environmental Restoration eligibility. This FAQ guide assists with identifying issues and promoting a consistent approach for dealing with lead-based paint at Navy Environmental Restoration sites. http://www.navfac.navy.mil/content/dam/navfac/Specialty%20Centers/Engine
The Navy has developed a toolkit to provide its RPMs with a resource to help improve the transparency and clarity of five-year reviews developed in accordance with CERCLA. The toolkit presents the use of visual communication methods that can enhance the review's overall presentation and emphasize the data, analysis, and rationale used to ensure protection of human health and the environment. Each of the 13 exhibits contains a "Toolkit Tip" to improve the quality and transparency of data presentation. The examples in the document neither replace existing Navy policy and EPA guidance nor substitute statutory and regulatory requirements for a five-year review. It is important during development of a review to include the level of detail recommended by EPA's Comprehensive Five-Year Review Guidance (OSWER 9355.7-03B-P, 2001) and consider the use of streamlining and visualization tools for better presentation of electronic data. http://www.navfac.navy.mil/navfac_worldwide/specialty_centers/exwc/produ
