Since 1998, The Contaminated Site Clean-Up Information (CLU-IN) website has presented Internet Seminars covering a wide variety of technical topics related to hazardous waste characterization, monitoring, and remediation. For select seminar topics offered since 2012, we are making complete video recordings available through our archives. This feed contains all video seminars archived in the last 12 months. For a complete list of seminars archived since 2000, please visit http://www.clu-in.org/live/archive/. Our Rehabilitation Act Notice for reasonable accommodation is available at http://www.clu-in.org/training/accommodation.cfm. CLU-IN was developed by the U.S. Environmental Protection Agency (EPA) but is intended as a forum for all waste remediation stakeholders.

Evaluating Plant Uptake Pathways of Chemical Contaminants in State Models for Risk Assessments of Contaminated Urban Gardening Sites (Dec 19, 2022)
Integration of urban agriculture into modern city planning has acquired an increased popularity in communities across the United States. Agriculture on the urban scale has proved to be a promising method to increase access to healthy, nutritious, and low-cost produce. Urban soil systems differ from their rural counterparts in terms of their physical and chemical properties. Due to their urban nature, the soil media used in these gardening plots are highly influenced by past and present anthropogenic activities that can threaten both soil health and food safety via chemical contaminants. Consequently, plant uptake findings from rural agricultural soils do not directly apply for risk assessment of urban soil media. This webinar will provide an overview of the following topics: contaminants of emerging concern (CECs) found at urban gardening sites, state-specific CECs, plant uptake of CECs from urban soil, and plant uptake models. A portion will be dedicated to outlining research and primary data gaps which require remediation to facilitate a more accurate characterization of potential exposure to ensure enough data is provided to form a national screening level.
