Hear from an EPA representative on practices for sample collection and analytical approaches to address microplastic pollution. Recent literature has shown that microplastics are ubiquitous in the environment and very commonly found in environmental water samples. Despite this the field is challenged by a lack of standard practices for sample collection and a lack of standardized analytical approaches. Older methods have been shown to be very inaccurate and imprecise. Newer methods show much promise for analytical reproducibility. These newer methods should be adopted for more routine monitoring practices.
Learning Objective(s):
After participating in this session, attendees will be able to:
- Discuss the extent, the mechanisms and resulting potential for harm from microplastic pollution.
- Describe the relative contribution of wastewater to microplastic pollution.
- Identify current policy positions in CA and within US EPA.

Harry Allen
LA Team Lead
US Environmental Protection Agency (EPA)
Harry has over 20 years of operations experience in large scale, multi-agency responses to major natural disasters, hazardous waste sites, oil spills and many other types of pollution incidents (USEPA Region 9; 2002-present). Areas of expertise include environmental study design, contamination estimation, and unique application of technology solutions to pollution monitoring and remediation.
Harry’s primary research interest is in studying the extent of microplastic particles in the environment. Harry created structures for the rigorous testing of microplastic sample collection and analysis with the ASTM D19-06 subcommittee. He designed and implemented several field studies collecting microplastic particles in marine & estuarine environments including at Tern Island, within the Papahanaumokuakea Marine National Monument (2018).
Harry has a B.S. from Rutgers University and an M.S. in Environmental Management from the University of San Francisco where he served as part-time faculty from 2007-2018. He has received three US EPA Gold Medals and the Federal Employee of the Year Team Award (2019) from the San Francisco Federal Executive Board.
