2026 Final Insufficiently Reclaimed Sites Quality Assurance Project Plan (Qapp), Pioneer Technical Services, Inc.

Silver Bow Creek/Butte Area Superfund Site

Insufficiently Reclaimed sites exist within the Butte Priority Soils Operable Unit (BPSOU) that could pose a threat to human health or surface water quality due to the exposure of historical mine waste. Although many source areas have been previously reclaimed, areas exist where reclamation was completed prior to the establishment of the Butte Hill Revegetation Specifications (BHRS) or reclaimed areas that have failed consecutive Butte Reclamation Evaluation System (BRES) inspections and now fall into either the Insufficiently Reclaimed or Reclamation Improvement category. In all these cases, additional work is required to comply with the BHRS to ensure the cap remains …

Unreclaimed sites exist within the Butte Priority Soils Operable Unit (BPSOU) that could pose a threat to human health or surface water quality due to the presence of historical mine waste. Although many source areas have been previously reclaimed, areas still exist in which soil has not yet been evaluated; such sites may provide a pathway for human exposure or impact surface water quality via stormwater runoff. These Unreclaimed sites will be evaluated in accordance with Appendix D, Attachment C, Section 8.0 of the BPSOU Consent Decree (referred to herein as CD) (EPA, 2020a).

Quantitative Mapping And Mitigation Of Light Pollution At Erau, Desireé Robinson, Marcus Flesher, Axon Deadrick, Conner Callahan, Jarrett Usui, Josef Kaelin, Douglas Griswold, Raiden Keefer, Harrison A. Zimmermann, Cole Gresham, Maya Curtis, Ahnika Gee

Discovery Day - Daytona Beach

Light pollution is an increasingly urgent environmental and public safety concern that affects energy costs, astronomical research, ecological systems, human health, and aviation. At Embry-Riddle Aeronautical University (ERAU), artificial lighting from campus infrastructure and adjacent airport operations contributes to elevated skyglow, limiting the performance of the university’s 1-meter telescope and degrading the nighttime environment. This project seeks to quantitatively map and analyze light pollution across the ERAU Daytona Beach campus using custom-built Sky Quality Meters (SQMs) integrated with environmental sensors and mounted on an unmanned aerial system (UAS). By collecting calibrated sky brightness measurements at multiple altitudes and geospatial coordinates, …

Influence Of Transboundary Wildfire Smoke On Fine Particulate Matter Concentrations At South Texas Border Schools, Sai Deepak Pinakana, Kabir Bahadur Shah, Owen Temby, Dawid K. Wladyka, Juan L. Gonzalez, Md Saydur Rahman, Katarzyna Sepielak, Amit U. Raysoni

School of Earth, Environmental, & Marine Sciences Faculty Publications

Exposure to air pollutants in indoor and outdoor school environments poses significant health risks to children due to their heightened vulnerability. Increasing wildfire frequency has intensified transboundary smoke transport, with border communities among the first to experience associated air quality impacts. While the impacts of wildfires on air quality are increasingly recognized through satellite observations and modeling, ground-based observations remain scarce in under-monitored regions. Low-cost air sensors were deployed across schools in the Roma and Rio Grande City areas of Starr County, along the U.S.–Mexico border, for 146-days from November 2023 to April 2024. The raw sensor measurements were corrected …

Variability In Nutrient And Enterococcus Concentrations In Tidal Floodwater Across Watersheds With Different Land Uses, Alyssa Bucci

OES Theses and Dissertations

Tidal flooding is an increasingly pressing hazard in coastal Virginia due to sea level rise and land subsidence. The Hampton Roads region of Virginia has the second-highest rate of relative sea level rise in the United States and experiences frequent tidal flooding, but the water quality impacts of this flooding on the Chesapeake Bay are not being accounted for. High concentrations of dissolved nutrients and Enterococcus bacteria (a fecal indicator) have been observed in tidal floodwater of the Lafayette River, a tributary of the James River and the lower Chesapeake Bay. This study investigates variability in dissolved nutrient and Enterococcus …
