We’re pleased to announce a new small business joint venture with Paul Bechtel & Associates (PB&A), which was awarded a 5-year contract to continue supporting the U.S. Environmental Protection Agency’s (EPA) Office of Pesticide Programs. 

For 40 years our staff have supported EPA’s Office of Pesticide Programs in the review and evaluation of pesticide data. Through this contract we assess pesticide safety─including its effects on non-target species and the endocrine system─as well as potential residues in crops.

Our new partnership brings together PB&A’s managerial experience with our team’s expertise in the scientific evaluation of pesticide data, and includes several additional team members with a history of supporting the Office of Pesticide Programs. This creates one top-notch team!
