Trihydro experts will head to Palm Springs, CA this April 2018 to present at the Battelle Conference. The Eleventh International Conference on Remediation of Chlorinated and Recalcitrant Compounds will be held April 8-12 at the Palm Springs Convention Center.

Here’s a list of our presenters and details about their presentations and poster sessions:

Bios:

Ben McAlexander
Mr. McAlexander is a contaminant hydrologist and supports fate and transport modeling, development of site conceptual models, and remedy selection/monitoring. He has experience pilot testing conventional and novel remedial technologies, focusing on test design prior to implementation. On remediation projects, he assesses the role of natural processes that can work in concert with engineered methods. He has field experience in UVOST, CPT, groundwater monitoring, well installation, and vapor sampling.


Daniel Mummert, P.E.
Mr. Mummert is a Licensed Professional Engineer with more than 13 years of experience leading aerial mapping, surveying, and civil engineering projects. He has conducted LiDAR and photogrammetric mapping projects nationwide using manned and unmanned mapping systems. His expertise includes Unmanned Aerial Systems (UAS) regulatory compliance, structure from motion and LiDAR data processing, and digital terrain modeling. He currently oversees UAS flight operations, and data processing for Trihydro. Additionally, he has severed as a project manager, design engineer and surveyor for drainage, utility. and site development projects for municipal, commercial and industrial clients. His responsibilities on these projects include drainage studies and stormwater management design, water and wastewater system design and modeling, and permitting.



Friedrich Krembs, P.E., P.G.
Mr. Krembs has over 13 years of experience working in environmental remediation. He has worked with private and government clients on site investigations, remediation alternatives assessments, remediation system design, and construction oversight. Mr. Krembs is well-versed in several in situ remediation technologies, with particular focus on in situ chemical oxidation (ISCO) and in-situ bioremediation (ISB). He has worked with recognized experts on developing a technology practices manual for ISCO. Mr. Krembs has managed many large and complex remediation projects using ISB, ISCO, and other technologies. He has also evaluated remediation of redox-sensitive metals. Mr. Krembs also has extensive field experience, including site characterization and design, remediation implementation/construction, performance monitoring and documentation of many ISCO and ISB projects.



Michael Sweetenham, P.G.
Mr. Sweetenham joined Trihydro in 2013 as a Geologist. His field experience includes drill crew oversight, geologic logging, fluid level gauging, aquifer tests, groundwater sampling and analysis, LNAPL baildown tests, ISCO, ISB, stream gauging and dilution tests, infiltration tests, well surveying, and ERT. His modeling experience includes physical and chemical processes in variably saturated geologic media, migration and concentration of contaminated groundwater, stream response to water-input, aquifer test analysis, and building 3D geologic models. Additionally, Michael can process large datasets using programs written in Fortran, C, and Visual Basic. Michael has supported projects in a variety of roles, including conceptual site model development, dataset analysis, technical report writing, and GIS figures.
