Coordinate the Virginia Household Water Quality Program, which affordable water testing and education to Virginians reliant on private water supplies (wells, springs, and cisterns) through extension offices in at least 65 counties annually. Partner with collaborating researchers to better understand private water supply water quality challenges. Applied research projects have focused on the following topics (collaborator and graduate student names in parentheses):

• Bacteria source tracking (Krometis, Allevi, Smith)
  
• Metals (lead) profiling (Pieper, Edwards, Krometis)
  
• Arsenic risk model (VanDerwerker, Schreiber)
  
• Contaminants of emerging concern/pharmaceuticals, personal care products and novel pesticides (Vesely, Xia)
• Bayesian belief models to predict lead in water (Berglund, Faesee, Pieper, Edwards)
• Strontium characterization (Scott, Juran)
  
• PFAS contamination (Krometis, Xia)
  
• Water equity, access and coping (Krometis)

Development and delivery of spray water testing program and supporting resources for Virginia agricultural producers

Development of social marketing and behavior change resources for community-based watershed organizations

Development and delivery of youth outreach focused on water quality (What’s in Your Water, Kids?)
