Today’s projects require a balance between society's demand for natural resources and the need to sustain healthy ecosystems. B&L’s professional geologists and environmental consulting staff specialize in planning, assessing, developing, testing, permitting, and protecting water and geological resources for both public and private sector concerns. Our knowledge of the regulatory agencies and expertise with complex water supply, wastewater discharge, and contamination challenges allows us to effectively interpret laboratory test data to formulate innovative and cost-effective solutions. Specifically, we achieve this by combining sound technical criteria with economic and community considerations.
