Adrienne LaPierre, Principal and President, (510) 834-4747 ext. 12, Download Vcard

Ms. LaPierre has more than 20 years of experience in environmental consulting, with emphasis on toxicology and human health risk assessment.

She has managed or performed multipathway risk assessments for Superfund sites, RCRA facilities, petroleum release sites, town gas sites, and various types of industrial properties. She has extensive experience in performing critical evaluations of the toxicological literature, defining dose-response relationships, establishing exposure limits, and evaluating potential causal associations between chemical exposures and documented adverse health effects.

Representative Project Experience

Mission Bay Development Project

Managed the human health and ecological risk assessment components of the Mission Bay Development project in San Francisco, California. She assisted in the design of a comprehensive sampling program to identify the environmental conditions at the site, and developed and implemented a risk-based evaluation to determine whether the site could be developed in a manner that would be protective of both human health and ecological populations.

She developed the risk management decision framework that will be followed throughout the 20-year development period to control potential impacts associated with the development of the site. Throughout the project, Ms. LaPierre has worked closely with the state, city and local regulatory agencies, and the other various stakeholders to negotiate a management plan that could meet the needs of all parties involved.

Former Gas Plant Remediation

Developed and implemented a statistically-based approach to the remediation of a former manufactured gas plant site. The former manufactured gas plant site has been occupied by 20 residential homes since the 1940s. Individual properties were contaminated with elevated levels of carcinogenic polycyclic aromatic hydrocarbons.

Ms. LaPierre worked with the local and state regulatory agencies to develop a remediation strategy that would be health protective and acceptable to the property owners. The remediation strategy involved the temporary relocation of all property owners and the removal of impacted soils. The Department of Toxic Substances granted individual Certificates of Completion for all 20 residential lots.

Indoor Air Quality Evaluation

Working with a southern California School District to evaluate indoor air quality impacts surrounding the use of portable classrooms. The project has included designing a statistically- based air monitoring program to determine the levels of chemicals and molds that may be attributable to the portable classrooms.

Working closely with members of a Technical Working Group, we developed indoor air health standards to identify and prioritize those portable classrooms that pose the greatest risk to the health of students and teachers. All targeted portable classrooms are currently the subject of additional evaluations.
