Know Your Enemy - Implementation of Bioremediation within a Suspected DNAPL Source Zone Following High-Resolution Site Characterization at Contractors Road Heavy Equipment Area, Kennedy Space Center, Florida

The National Aeronautics and Space Administration (NASA), Kennedy Space Center (KSC), has adopted high-resolution site characterization (HRSC) sampling techniques during baseline sampling prior to implementation of remedies to confirm and refine the conceptual site model (CSM). HRSC sampling was performed at Contractors Road Heavy Equipment Area (CRHE) prior to bioremediation implementation to verify the extent of the trichloroethene (TCE) dense non-aqueous phase liquid (DNAPL) source area (defined as the area with TCE concentrations above 1% solubility) and its daughter product dissolved plume that had been identified during previous HRSC events. The results of HRSC pre-bioremediation implementation sampling suggested that the TCE source area was larger than originally identified during initial site characterization activities, leading to a design refinement to improve electron donor distribution and increase the likelihood of achieving remedial objectives. Approach/Activities: HRSC was conducted from 2009 through 2014 to delineate the vertical and horizontal extent of chlorinated volatile organic compounds (CVOCs) in the groundwater. Approximately 2,340 samples were collected from 363 locations using direct push technology (DPT) groundwater sampling techniques. Samples were collected from up to 14 depth intervals at each location using a 4-foot sampling screen. This HRSC approach identified a narrow (approx. 5 to 30 feet wide), approximately 3,000 square foot TCE DNAPL source area (maximum detected TCE concentration of 160,000 micrograms per liter [micro-g/L] at DPT sampling location DPT0225). Prior to implementation of a bioremediation interim measure, HRSC baseline sampling was conducted using DPT groundwater sampling techniques. Concentrations of TCE were an order of magnitude lower than previous reported (12,000 micro-g/L maximum at DPT sampling location DPT0225) at locations sampled adjacent to previous sampling locations. To further evaluate the variability in concentrations observed additional sampling was conducted in 2016. The results identified higher concentrations than originally detected within the previously defined source area and the presence of source zone concentrations upgradient of the previously defined source area (maximum concentration observed 570,000 micro-g/L). The HRSC baseline sampling data allowed for a revision of the bioremediation design prior to implementation. Bioremediation was implemented within the eastern portion of the source area in November and December 2016 and quarterly performance monitoring was completed in March and June 2017. Reductions in CVOC concentrations from baseline were observed at all performance monitoring wells in the treatment area, and by June 2017, an approximate 95% CVOC mass reduction was observed based on monitoring well sampling results. Results/Lessons Learned: The results of this project suggest that, due to the complexity of DNAPL source zones, HRSC during pre-implementation baseline sampling in the TCE source zone was an essential strategy for verifying the treatment area and depth prior to remedy implementation. If the upgradient source zone mass was not identified prior to bioremediation implementation, the mass would have served as a long-term source for the dissolved plume

On the well-posedness of a mathematical model describing water-mud interaction

In this paper we consider a mathematical model describing the two-phase interaction between water and mud in a water canal when the width of the canal is small compared to its depth. The mud is treated as a non-Netwonian fluid and the interface between the mud and fluid is allowed to move under the influence of gravity and surface tension. We reduce the mathematical formulation, for small boundary and initial data, to a fully nonlocal and nonlinear problem and prove its local well-posedness by using abstract parabolic theory.Comment: 16 page

Geochemical and microbial community determinants of reductive dechlorination at a site biostimulated with glycerol

Biostimulation is widely used to enhance reductive dechlorination of chlorinated ethenes in contaminated aquifers. However, the knowledge on corresponding biogeochemical responses is limited. In this study glycerol was injected in an aquifer contaminated with cis-dichloroethene (cDCE), and geochemical and microbial shifts were followed for 265 days. Consistent with anoxic conditions and sulfate reduction after biostimulation, MiSeq 16S rRNA gene sequencing revealed temporarily increased relative abundance of Firmicutes, Bacteriodetes and sulfate reducing Deltaproteobacteria. In line with 13C cDCE enrichment and increased Dehalococcoides mccartyi (Dcm) numbers, dechlorination was observed towards the end of the field experiment, albeit being incomplete with accumulation of vinyl chloride. This was concurrent with i) decreased concentrations of dissolved organic carbon (DOC), reduced relative abundances of fermenting and sulfate reducing bacteria that have been suggested to promote Dcm growth by providing electron donor (H2) and essential corrinoid cofactors, ii) increased sulfate concentration and increased relative abundance of Epsilonproteobacteria and Deferribacteres as putative oxidizers of reduced sulfur compounds. Strong correlations of DOC, relative abundance of fermenters and sulfate reducers, and dechlorination imply the importance of syntrophic interactions to sustain robust dechlorination. Tracking microbial and environmental parameters that promote/preclude enhanced reductive dechlorination should aid development of sustainable bioremediation strategies.

The least restrictive supplement

Project (M.A., Education (Special Education)) -- California State University, Sacramento, 2011.This project was a collaboration of work created by Carolyn DaPrato and Randi Sindt. The authors worked closely together to assist the Placer Union High School District (PUHSD) in creating a mathematical supplement focused on number sense to support any currently adopted mathematical curriculum that students with moderate to severe disabilities may be using for educational benefit. The authors were motivated to create a tool that the PUHSD could use to close the achievement gap between the alternate assessments content standards and the core curriculum content standards. The authors found the process of continual communication and consistent meetings with each other were vital throughout the process of creating this project. Both authors researched the project and created a Likert questionnaire as well as developed The Least Restrictive Supplement collaboratively.\ud The PUHSD special education teachers brought to the authors??? attention a need for a mathematical number sense curriculum that meets the needs of students??? with moderate to severe disabilities. Teachers within the field of special education are finding that students with moderate to severe disabilities need a curriculum that aligns with California core content standards and scaffolds down to CAPA level standards in order for students to make progress on state mandated assessments. The authors analyzed and researched the accountability policy authorized by No Child Left Behind (NCLB) 2001 and the Individual with Disability Act (IDEA). Based on the information gathered the authors created a mathematical curriculum focused on number sense to assist the PUHSD staff whom are serving students with moderate to severe disabilities. The creation of this curriculum would close the gap between alternate assessment standards and core curriculum content standards presented to students in both curriculum and statewide assessments.\ud The authors analyzed mathematical curriculum currently adopted by PUHSD to see what areas of content were being addressed, what standards were being addressed, and if the curriculum could assist the specificities required of a special educator to complete an Individualized Education Plan (IEP). The authors also conducted a likert questionnaire asking special education teachers and school psychologist within district what they believe is an area of need for students with moderate to severe disabilities. The questionnaire also gathered information on the importance of what should be included in a curriculum. \ud Once the authors gathered data they created The Least Restrictive Supplement and then they reconvened with the participants of likert questionnaire to receive feedback on their project. \ud Even though it was the intent of authors to develop a mathematical number sense curriculum, the author created a mathematical number sense supplement. The Least Restrictive Supplement was created to address the needs of a curriculum that aligns with California core content standards and CAPA standards. The Least Restrictive Supplement encompasses content pages which contain: CAPA standards, CARS+ goals, two benchmarks as well as monitor students??? progress. The supplement also enclosed worksheets in addition to assessments to help students with comprehension of the concepts. Upon the completion of The Least Restrictive Supplement the participants of the likert questionnaire provided feedback. Overall the participants thought that the supplement would be beneficial to their students with moderate to severe disabilities at PUHSD.Education (Special Education
