On-Site Analysis:
EMA offers a variety of on-site analytical testing of
soil, groundwater and soil gas using portable field instruments, calorimetric
methods, or immunoassay testing. For petroleum discharge sites, EMA
typically uses USEPA headspace gas chromatography (GC) method 3810
and/or purge and trap methods 601/602 to evaluate relative concentrations
of volatile organic compounds such as BTEX. The Mobile Laboratory is equipped
with an SRI Model 9300 GC with PID, FID and dry ELCD detectors.
The versatility of this unit also allows EMA to
customize non-standard methods for investigation of other types of discharges
including halogenated and non-halogenated solvents and PCB's.
EMA's highly sophisticated on-site testing provides real time data to
the investigator that can be interpreted in the field and used to focus
the investigation on recognized hot spots in the study area. This type
of advanced field screening can reduce the overall number of samples
requiring analysis at an offsite laboratory, thereby expediting site
delineation and reducing project costs and schedules.
