Phase I, II, and III Environmental Site Assessments (ESAs) There is a plethora of written information concerning Environmental Site Assessments (ESAs), but quite simply an ESA is an investigation of real or possible environmental concerns associated with a property. The initial investigation of a property is usually referred to as a Phase I ESA, or simply a "Phase I". The primary intent of a Phase I ESA is to provide liability protection to a prospective purchaser, lender, or other party associated with a property transaction, particularly for industrial or commercial property, but increasingly for larger farms and ranches as well. ESA procedures are detailed in various documents such as ASTM 1527-05, which is the standard procedure followed by RMEA. The work scope of a Phase I includes both a detailed on-site inspection of the property, and research of existing information and records that might reveal environmental conditions associated with a property. Liability protection can be jeopardized if the environmental firm conducting the project uses inexperienced staff who lack the proper qualifications and experience. ESAs represent a core business service provided by RMEA since inception, and RMEA has performed many hundreds of ESAs in Idaho and surrounding states since 1991. Our ESA team is headed by John Rice. John has managed and conducted ESAs across the U.S., beginning in 1987. Our ESA team includes Roger Warner, Doug Davidson, Pam Reed, and Alex Warner. Landfill Monitoring and Statistics RMEA has provided a range of services to our landfill clients, including routine groundwater monitoring, installation of groundwater monitoring wells, hydrogeologic characterizations, statistical analyses of water quality data, and calculations of greenhouse gas emissions and associated reporting. Our landfill clients include several eastern Idaho counties. Our extensive experience with water quality studies and hydrogeologic characterizations allows RMEA to provide the highest level of technical service to our landfill clients. Underground Storage Tank (UST) Closures Many of RMEAs site investigation and remediation projects have been the result of leaking underground storage tanks (LUSTs). Our staff have extensive experience conducting tank-related projects since the 1980s, both in the Rocky Mountain region and across the U.S. Water Quality Studies Many of RMEAs projects involve water quality sampling and analysis. Our staff have many years experience with Water Quality projects throughout the region. RMEA maintains a wide range of groundwater and surface water sampling and in-field analytical equipment. Nutrient-Pathogen (NP) Studies RMEA conducts Level 1 and Level 2 Nutrient-Pathogen (NP) studies as per Idaho Dept. of Environmental Quality guidance. The selection of the appropriate input parameters into these models is the most important aspect of conducting a proper NP study. In particular, it is crucial with these models to select appropriate and defensible hydraulic conductivity and groundwater gradient values, as these parameters control the groundwater flow velocity at a site, which in turn controls the rate of waste-water contaminant attenuation.
