Toxic Chemicals & Hazardous Substances

Managing toxic chemicals and hazardous substances requires agencies to evaluate risks across industrial processes, consumer products, and areas affected by legacy contamination. Abt Global helps state and federal agencies navigate this complexity through chemical risk evaluations, rigorous analysis for rulemakings, and hazardous substance planning. 

Our work translates nuanced chemical exposure pathways and toxicity data into the foundation of defensible decisions that safeguard public health and the environment.
