Collected and logged stormwater grab samples at 14 construction and municipal sites across the Denver metro area, following CDPHE and EPA field protocols with 100% chain-of-custody compliance. Performed 30+ SWPPP and BMP inspections, documenting deficiencies with GPS-tagged photos and recommending corrective actions that were closed out within 7 days on average. Prepared 9 AutoCAD Civil 3D drainage and grading drafts, including culvert, swale, and detention basin layouts, for senior engineer review. Managed lab QA/QC data for 250+ samples in Excel and ArcGIS Pro, flagging 12 out-of-range results and mapping exceedances for client reports. Built reusable Excel templates and map layouts that helped cut report turnaround by 20%.

Prepared and digested 120+ water and soil samples for PFAS and trace-metals analysis under EPA Method 1633 and 200.8 quality protocols. Cleaned and validated ICP-MS output for 5,000+ data points using Python (pandas), reducing manual spreadsheet review time by roughly 35%. Co-authored a research poster on PFAS occurrence in Front Range surface water, presented at the campus undergraduate research symposium. Maintained calibration logs, blanks, and duplicates for all batches, keeping QC recoveries within 85-115% acceptance limits. Trained 4 new student assistants on clean sampling technique, chain-of-custody forms, and lab safety procedures.

Conducted 60+ erosion and sediment control inspections at active construction sites, logging findings in the city's permit-tracking system. Screened 45 MS4 stormwater outfalls for illicit discharges, recording flow, odor, color, and turbidity observations during dry-weather surveys. Mapped 300+ storm inlets and manholes with sub-meter GPS, producing a clean asset layer that replaced outdated paper records. Supported the MS4 annual report by compiling inspection counts, photos, and corrective-action tracking for 3 permit program areas. Collaborated with a 6-person field crew to respond to 10+ resident drainage complaints, reporting hazards to supervisors the same day.

OSHA 10-Hour Construction Safety Card — OSHA Outreach Training Program (2024) Fundamentals of Engineering (FE) Exam — Environmental, passed Oct 2025 (NCEES) HAZWOPER 40-Hour Hazardous Waste Operations and Emergency Response — 29 CFR 1910.120 (2025)

Senior Design — Constructed Wetland for Mine Drainage: designed a 3-cell constructed-wetland treatment system for abandoned-mine drainage (target 0.5 cfs), sized cells with HEC-RAS and modeled metals removal to meet projected effluent limits with a 4-person team. Campus Rain-Garden Infiltration Study: measured infiltration rates at 6 sites with double-ring infiltrometers, found 38% higher infiltration in amended soils, and presented recommendations to campus facilities.
