Ms. Sitler has over 20 years of practical experience providing geologic and hydrogeologic consultation, management, and human health risk assessment for the characterization of contaminated sites and providing strategic planning with clients for compliance with federal, state, and local regulatory requirements. She has prepared human health risk assessments for Superfund mining sites by assessing the exposure to lead and other heavy metals. Ms. Sitler has applied this experience to mining sites in Missouri’s New and Old Lead Belts and in Arizona, Colorado, and Idaho. She has experience with the IEUBK child lead model and the adult lead model and is one of the few risk assessors that has experience applying both models to intermittent exposure. Ms. Sitler has managed and participated in soils, groundwater, surface water, waste, and wastewater sampling programs and has provided technical review and strategic planning for Resource Conservation and Recovery Act (RCRA), Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), and various state’s priority list and voluntary cleanup sites. Ms. Sitler combines a technical background in hydrogeology and human health risk assessment to support management decisions in environmental remediation projects. Her recent projects include residential yards cleanups and feasibility studies for the protection of aquatic life water quality criteria in mountain streams. Her years of experience have given her a unique view of data collection and data quality to support both project remedial decisions as well as legal decisions. Ms. Sitler earned her B.S. in geology and a M.S. in geology.
