The June sucker (Chasmistes liorus) is a federally-listed endangered fish endemic to Utah Lake. Junesucker spend the majority of their life cycle in Utah Lake, but enter tributary streams each spring to spawn. Provo River is the primary June sucker spawning tributary, but historically the fish most likely spawned in multiple tributaries. Alterations associated with flow withdrawals, diversion structures, and channelization have greatly limited or precluded access to suitable spawning habitat in tributaries other than Provo River. In addition, we obtained electrical, natural gas, and telephone utility services for the remediation systems and provided construction management and labor for system installations that included 62 aquifer sparging wells, 88 soil vapor extraction (SVE) wells, 2 catalytic oxidizers, 1 thermal oxidizer, and associated aquifer sparging and SVE blowers. System installation included supervision of drilling crews, electricians, excavators, asphalt crews, and laborers. The remediation systems removed the free product and reached the 100 percent cleanup milestone in less than 3 years of operation.
