• Coordinated and performed vertical, as well as, horizontal air sparge, soil vapor extraction (SVE), vacuum enhanced groundwater extraction (VEGE), and total-phase extraction (TPE) remediation feasibility testing at a number of project sites.• Designed a groundwater extraction and treatment (GWE&T) system to capture, recover, and treat light non-aqueous phase liquid (LNAPL) contaminated groundwater in a tidal wetland. • Conducted oversight of construction activities including geophysical investigative surveying, excavation, horizontal drilling, monitoring/ extraction well installation, carbon vessel mobilization and de-mobilization, and remediation system installation.• Coordinated, and performed chemical injections of various remedial solutions.• Managed operation and maintenance (O&M) of GWE& T, SVE, air sparge (AS)/ SVE, VEGE, and sub-slab depressurization (SSD) remediation systems installed at industrial manufacturing facilities, bulk petroleum terminals, and petroleum retail stations.• Prepared applications and renewals for National Pollution Discharge Elimination System (NPDES) permits.• Prepared and submitted regulatory compliance reports for air, groundwater, and industrial stormwater discharge permits including NPDES discharge monitoring reports (DMRs), request for determinations (RFDs), remedial action plans (RAPs), and local township permitting.

Newark, De

• Accompanied a team to conduct field sampling of water quality within the Christiana watershed• Surveyed stream cross-sections for specific sub-watershed• Conducted spatial analyses with GIS on watershed characteristics such as soil classification, land use, flood plains etc.• Compiled reports outlining watershed action plans for watershed in question

University Of Delware

• Conducted field surveying of industrial facilities in order to identify current practices and determine major sources of electrical energy consumption• Computed calculations for projected energy resource savings as well as reductions in carbon emissions• Compiled and provided reports to clients outlining recommendations to be implemented in facilities in order to reduce consumption and operate at optimal efficiency.

• Created the agenda and designated tasks to members of the environmental engineering team • Redesigned a stream channel in order to reduce sediment deposition using natural stream parameters• Computed current conditions analyses of soil and groundwater contaminant levels at project site• Computed complex calculations to determine the radius of influence required for groundwater wells• Designed alternative solutions to remediate the groundwater treatment facility to contain the contamination• Used tools such as RACER and ISI to determine the most efficient solution based on cost and environmental impact• Liaised with civil, transportation and structural team leaders to coordinate project goals and meet deadlines
