Why are mobile/portable analytical systems needed for natural attenuation studies?
EAM designs and operates analytical systems that maximize representativeness, accuracy and precision. All data generated by EAM is conducted in accordance with USEPA methods and Quality Assurance procedures, resulting in scientifically and legally defensible data (1,2,3). The understanding of continuous biogeochemical equilibriums and cycles that occur in groundwater ecosystems can be quite complicated (4). The moment a sample is removed from the biogeochemical equilibriums that exist in-situ, the water chemistry of the sample begins to change. Sampling procedures, temperature and pressure variations, removal from geological contact, exposure to the atmosphere, photo-degradation, biodegradation, preservation, containerization and transportation effect the chemistries of the compounds of interest. When one looks at these data variables and applies the data for quantitative interpretation (i.e. numerical modeling), the range of output could be significant, rendering data with low confide
