Former Agricultural Chemical Formulation and Distribution Facility, California, Confidential Client

The project included soil and groundwater sampling, groundwater monitoring, and a sensitive receptor survey as part of a remedial investigation and feasibility study (RI/FS) for a 10-acre former agricultural chemical formulation and distribution site, The site was impacted by fuel hydrocarbons, fuel oxygenates, pesticides, soil fumigants, herbicides, and chemical fertilizers. A total of 16 ground water monitoring wells and six piezometers were installed. A pumping test was conducted with multiple observation wells to determine ground water flow characteristics. An adjacent water distribution canal was also monitored as a part of the hydrogeological environment. A pilot-scale phytoremediation study was conducted using hybrid poplar and willow tree species. Soil mixing and spreading was utilized to mitigate fertilizer hot-spots prior to planting. The rhysomal uptake of fertilizers and irrigation water was monitored throughout the pilot study, which served to demonstrate the feasibility of this approach for site remediation.

Industrial Nitrogen Operations Facility, California, Confidential Client

The subject site is a large-scale nitrogen fertilizer formulation facility, with on-site storage of liquid ammonia, acids, caustics, urea, and other fertilizer additives. The project included site characterization including soil and ground water sampling, ground water monitoring in multiple wetted zones, a sensitive receptor survey, preparation of risk management plans, process hazard analyses, and a study of a ground water extraction barrier along an adjacent deep shipping channel.

Former Agricultural Chemical Distribution Facility, Central California, Confidential Client

The site is an active agricultural chemical distribution and storage facility, which included bulk dry fertilizers, bulk liquid fertilizer products, and packaged pesticides, fungicides, herbicides, and soil fumigants. The project included soil and groundwater sampling, groundwater monitoring, a sensitive receptor survey, ground water pumping tests, as part of a remedial investigation and feasibility study (RI/FS), The site was impacted by fuel hydrocarbons, fuel oxygenates, pesticides, soil fumigants, herbicides, and chemical fertilizers. A total of 21 ground water monitoring wells in multiple wetted zones were installed and monitored.
