Each Phase II Environmental Site Assessment (ESA) is unique and often requires the use of multiple assessment techniques in order to achieve the objectives. Dependent upon the Phase II ESA objectives, the collection of soil and/or groundwater samples is often difficult. Obstacles typically encountered during Phase II ESA activities include, but are certainly not limited to subsurface utilities (e.g. natural gas, sewer, electric), overhead or nearby powerline concerns (arc sparking), heavy vegetation, variable topography, or the presence of structures in the areas to be assessed. In many cases, environmental consulting firms are unable to collect samples in suspect areas of a property, which were identified as environmental concerns during the course of the preceding Phase I ESA.
As shown in the photograph for this discussion, access limitations (width and height) resulted in the inability to utilize typical soil boring equipment, such … Read More »
Mold Growth in Austin hotel behind wallpaper. This Austin hotel had some issues in the past with roof leaks around the window frames. With the torrential rains the Central Texas area received last spring, these issues became more prevalent. Farmer Environmental Group were called out to perform moisture and mold-growth mapping. Farmer’s licensed professional, Cameron Cadenhead, visited the job site every day over the span of about two weeks; going through rooms that the hotel management staff had designated for him. Cadenhead used a moisture meter to locate walls with elevated moisture and marked them on the floor plans that the hotel staff provided. He visually inspected the walls to assess the extent of the mold growth behind the vinyl wallpaper. Various shades of pink and blue were visible on some areas of the wallpaper. This indicated that mold was … Read More »
Thermal investigation at surgical center.
Farmer utilized a Flir (E5) IR camera to conducted a thermal investigation of a surgical center that was impacted by a water intrusion from a busted water main. Farmer’s use of the thermal imaging camera along with verification using a pin moisture meter allowed for the client to remove and/or dry out all wet building materials as to not allow microbial growth within the damaged areas. The use of the IR camera allowed Farmer to assess the affected areas to determine what was restorable vs what materials must be remediated. This use of this application also allowed the client to remediate the surgical area with minimal downtime and gave confidence that there would be no future microbial growth issues associated with the water intrusion.
