Through her practice, Beth frequently aids clients in the design, permitting, and monitoring of alternative and conventional liner systems and cover systems for waste containment and remediation sites. She is a nationally recognized authority on the performance of waste containment systems, including evapotranspirative cover systems and geosynthetics applications. She also provides leadership for a wide range of geotechnical engineering projects across the firm, including geotechnical investigations, stability and settlement assessments of soil slopes and foundations, forensic investigations of slope failures, slope stabilization, and foundation design.
To advance the state of the practice, Beth gives frequent presentations and peer-reviewed technical papers on geotechnical engineering and waste containment systems. She has played a major role in developing technical support and guidance for U.S. Environmental Protection Agency (EPA), including draft Technical Guidance for RCRA/CERCLA Final Covers; Assessment and Recommendations to Optimize the Field Performance of Waste Containment Systems; Evaluation of Liquids Management Data for Double-Lined Landfills; Waste Containment System Problems and Lessons Learned; LDCRS Flows from Landfills and Surface Impoundments; the Karst Terrains Guidance Manual; and Comparative Performance of Single-Liner and Double-Liner Systems. She also provided technical assistance to the U.S. EPA for finalization of the Liner/Leak Detection System Rule. Most recently she co-authored the Electric Power Research Institute's guidance document Coal Combustion Residuals Pond Closure: Dewatering and Capping.
Beth is a registered civil engineer in 12 states and a member of the American Society of Engineers (ASCE). In June 2014, she accepted an invitation to join the Board of Governors for the ASCE Geo-Institute for a three-year term. Beth has been a member of the Geo-Institute's Geoenvironmental Engineering Committee since the early 1990s and was its chair between 2000 and 2005. She also is a member of the Institute's Technical Coordination Council, Awards Committee, and Continuing Education Committee and is an editor of the Institute's Geo-Strata magazine. In 2018, Beth was named President of the Geo-Institute.
