Terracon Foundation demonstrated exceptional commitment to employee engagement in philanthropic projects and fundraising partnerships throughout 2024. The foundation awarded $500,000 to organizations that advance the firm’s core mission of supporting education, the built and natural environment, and equity while fostering a culture of giving among employees. Terracon approved a landmark grant of $26,000 to the AIHA Foundation (AIHF) to establish the Women in Industrial Hygiene-Terracon Leadership Scholarship. Once finalized, this endowed scholarship will award $1,000 per year to undergraduates, graduates, and professionals in the industrial hygiene (IH) space who have advanced women’s leadership in the IH profession.
True to its strategic plan, Terracon successfully expanded its capabilities and market presence by acquiring four specialized environmental firms in 2024, demonstrating dynamic acquisition leadership:
In 2024, Terracon worked with the Salt River Pima-Maricopa Indian Community (SRPMIC) to prepare their implementation grant application for EPA’s Climate Pollution Reduction Grant program.
