Perchlorate Groundwater Investigation, Barstow, California
A Southern California regulatory agency suspected that illegal disposal of perchlorate had impacted the soil and groundwater of a residential property located in Barstow, California. A groundwater investigation project was conducted at a suspected source of perchlorate site, and extended 1.5 miles offsite. The groundwater investigation project fully delineated the extension of perchlorate impacted groundwater and identified remediation alternatives.

Biological Wastewater Treatment and Operations Training in Argentina
A wastewater treatment process at a potato processing plant located in Argentina was experiencing continuous upsets with their activated sludge treatment system. A hands-on training program was implemented to teach operators to monitor and control the two existing biological treatment processes consisting of a low rate anaerobic wastewater treatment pre-treatment and an activated sludge treatment system.
