Select Projects

Site Ecological Risk Assessments:  Conducted ecological risk assessments at numerous US and international contaminated sites.

Environmental Stewardship:  For global companies, evaluated the environmental safety of their products to support sustainability goals.

Pharmaceutical Environmental Risk Assessments:  For pharmaceutical companies, evaluated the environmental risk of their new drugs to support market approval, compliant with either European (European Medicines Agency [EMA]) or US (Food and Drug Administration [US FDA]) guidelines.  As part of several assessments, oversaw the collection of additional environmental fate and toxicity test data.

Secondary National Ambient Air Quality Standards (NAAQS):  On behalf of trade associations, provided written and oral comments to the Clean Air Scientific Advisory Committee (CASAC) and to US EPA on welfare risk and exposure issues in the context of US EPA’s NAAQS for ozone and lead.

Emerging Contaminants:  In the context of a wide variety of projects, provided consulting and expert support related to the environmental safety of various contaminants of emerging concern, such as endocrine disruptors, pharmaceuticals, 1,4-dioxane, PFAS, microplastics, etc.

Endocrine Disruptors:  For companies, trade associations, and government (US EPA), provided technical expertise related to the topic of endocrine disruption.
