TOXICOLOGY 101: Using Toxicological Information in Emergency Resp M-F1

Monday 8am to 10am

Room	GOLD KEY I/II
Seating	8 of 108 seats available
Credits	REHS: 2.0
Speakers	Karen Riveles
Objective	Introduction to basic toxicological principles; understand health guidance values and how chemicals are reviewed for toxicity; and how this information is used before, during, and after emergencies to protect public health and the environment and assist in cleanup decisions.
Description	This course will introduce basic concepts related to understanding the toxicity of chemicals. We will provide an overview of basic principles of toxicology and human health risk assessment of hazardous chemicals.

SUSTAINABILITY IN GW REMEDIATION NON-PETROLEUM VI EVAL FOR UST TU-F3

Tuesday 3pm to 4pm

Room	GOLD KEY I/II
Seating	55 of 100 seats available
Credits	REHS: 1.0
Speakers	Yue Rong, Maryam Renard
Objective	This presentation will provide a discussion on sustainability in groundwater remediation, from environmental, economical, and social angles.
Description	Conventional environmental groundwater remediation methods usually include physical means to clean up contamination sources, such as excavation, pump, extraction, bury, and burn. Coming into 21st century, the remediation industry starts to emphasize sustainability in site cleanup, which requires consideration of lower use of resources and energy (e.g., lower emission) and resource conservation. In a design of site remediation, the factors such as energy, resources, climate change, green technology, safety and risk evaluation, cost benefit, and public acceptance may be considered. Sustainability is evaluated based on environmental, economic, and social considerations. This presentation will evaluate first cost analysis using case study in Los Angeles Region, which used 179 closed cases of active remediation since 2012. The average cost of cleanup with all methods is about $887,438 per site. Cost for individual remedial method such as soil vapor extraction is also analyzed. For example, cost for average soil vapor extraction is about $926,173 per site, which is higher than the average cost per site. The presentation also discusses the relationship between the cleanup goal and sustainability. Some individual site remedial methods, including soil excavation, groundwater pump and treat, soil vapor extraction, thermal enhancement, dual-phase extraction and air sparging, vapor barrier installation, chemical and biological in-situ treatment, monitoring natural attenuation, and phytoremediation, are also evaluated per the perspective of sustainability.

UPDATE ON WATER BOARD CLEANUP PROGRAMS, VI, AND AB304 W-F1

Wednesday 8am to 10am

Room	GOLD KEY I/II
Seating	58 of 100 seats available
Credits	REHS: 2.0
Speakers	Cheryl Prowell, Gregory Shaffer
Objective	Learn about changes within the Site Cleanup Program at the Water Boards and Local Agencies, and vapor intrusion guidance and policy progress
Description	This course is an overview of what's new within the Site Cleanup Program at the Water Board including updates regarding statewide investigations for PFAS, updates to vapor intrusion guidance, and progress toward developing a vapor intrusion policy. We will also provide an update on the changes to the Local Agencies Cleanup Programs, observations, and lessons learned since the passage of AB304.

VAPOR SAMPLING FRAMEWORK, CHARACTERIZING PFAS IN CA WATERS W-F2

Wednesday 10am to 12pm

Room	GOLD KEY I/II

Description	State-wide investigative orders have been issued to target known sources or secondary sources of PFASs and nearby public water supply wells. Those investigations are ongoing and provide invaluable data on the magnitude of the issue for targeted PFAS analytes. The findings of a limited study revealed elevated concentrations of non-targeted PFAS analytes and highlight the present challenge to characterize the full scope of the problem.
