Geosyntec News and Events

Geosyntec, a thought leader among environmental science and engineering firms, recently devised an innovative approach to rescue a client from a long-standing site condition where dissolved fluoride impacted groundwater at high enough levels to impair water quality and require cleanup. Fluoride releases are uncommon, but when this does occur the solubility of fluoride often results in groundwater contamination. Led by Chris Herin, the Geosyntec project team recognized that soil excavation was too disruptive to site…
In the early decades of Clean Air Act implementation, it was common for permitting agencies to require facilities seeking Prevention of Significant Deterioration (PSD) permits to conduct pre-construction ambient air quality monitoring prior to permit issuance. While less common, it was not unprecedented to require facilities to conduct post-construction ambient air quality monitoring to confirm that the new or modified facility would not cause a violation of a National Ambient Air Quality Standard or consume…
