About Erica DiFilippo

Dr. DiFilippo has extensive experience addressing the fate and transport of organic and inorganic chemicals in the environment. She has conducted numerous studies of groundwater transport, statistical geochemical analysis, groundwater age-dating, dense non-aqueous phase liquid (DNAPL) dissolution, enhanced DNAPL remediation technologies, and the use of innovative technologies for measuring in-situ concentrations of organic contaminants in sediment pore-water. Dr. DiFilippo is an active member of the PFAS team with the Interstate Technology Regulatory Council (ITRC) and has contributed to the Physical and Chemical Properties and Fate and Transport sections of the main document and its associated fact sheets. She also provided support for ITRC’s web-based PFAS expert roundtables. Dr. DiFilippo has also contributed to responses written by the National Ground Water Association (NGWA) regarding PFAS regulations. For geochemical studies, she as applied various statistical methods (ANOVA, tolerance and prediction limits, confidence limits, cluster analysis, principal component analysis, trend analysis) to evaluate background concentrations and the impact of site activities on groundwater contaminants. Dr. DiFilippo has extensive experience coding in R and LaTeX and has developed several R packages for data processing and analysis. Dr. DiFilippo has authored several publications related to organic and inorganic geochemistry and groundwater transport. .Read More

Erica DiFilippo's Current Workspace

S.S. Papadopulos & Associates, Inc.
S.S. Papadopulos and Associates, Inc. (SSP&A) was established in 1979 to provide professional groundwater and hydrogeology consulting services. With that cornerstone of expertise, we have continued to grow and have developed a recognized practice in contaminant studies, environmental engineering, remediation, geochemistry, and surface-water hydrology. In addition to addressing site-specific water resource and contamination projects, SSP&A staff have been retained as expert witnesses and technical experts in high-profile judicial, administrative, and regulatory forums. Several SSP&A staff have been appointed to prestigious federal committees investigating current issues in contamination and remedia
