Microseeps offers a series of specialty analyses designed to accurately and reliably quantify the presence of specific suites of analytes used to evaluate subsurface processes.

Compound Specific Isotope Analysis (CSIA)

CSIA is an evolving technique which is used to more definitively characterize processes in groundwater which degrade contaminants of concern such as BTEX, MTBE and CVOC's. The data that is generated by CSIA can be used to unambiguously determine that biodegradation of these contaminants is occurring, may be able to identify the process of degradation as aerobic or anaerobic and in some cases determine the rate and extent of degradation.

Supporting Monitored Natural Attenuation / Enhanced Biodegredation

Microseeps offers specialty analytical services and proprietary technologies to support MNA. In particular, our dissolved gas analyses and our anion/cation analyses can be used to delineate redox zones and thus determine the achievable rates of various transformations of predominant TEAPs (terminal electron acceptor processes).

Bio Trap Sampling and Supporting Analyses

A large component of monitored natural attenuation (MNA) or enhanced bioremediation is demonstrating that biodegradation processes are occurring or can occur at a given site. Microseeps, in a collaborative effort with Microbial Insights, has expanded the capabilities of Bio-Trap Samplers to not only determine the microbial response, but to also assess the presence and acceleration potential of degradation of a given contaminant in-situ.

Solid Phase Analyses for Bioremediation are used to assess the quantity of iron that can participate in bioremediation as well as the quantity of reduced iron and sulfide bioremediation products.   Microseeps offers these analyses in three variations:  AMIBA, Bioavailable Ferric Iron, and a combination of AMIBA with bioavailable ferric iron.

Supporting Enhanced Biodegradation

With enhanced biodegradation (substrate injection) becoming a remediation technology of choice, Microseeps offers a number of analytical packages to support a better understanding of their progress. A key new analysis is volatile fatty acids via ion chromatography. This method has achieved significantly lower detection levels and is ideal for remedial approaches using the addition of organic substrates for stimulation of anaerobic degradation.

Microseeps has developed a method for determining Total Inorganic Carbon (TIC) that takes the guess work out of calculating TIC across a site. If TIC is measured before and after a stimulated degradation process is implemented, the difference in TIC is the amount of organic carbon converted to inorganic carbon during the stimulated degradative process.

Supporting the Remediation of Fuel Oxygenates

Most gasoline plumes today also contain fuel oxygenates. Microseeps has developed an analytical method that quantifies all hydrocarbon and oxygenate analytes commonly found in reformulated gasoline. Based on this method development, Microseeps has worked with USEPA to update existing methodologies to include the fuel oxygenates as named analytes and to include revisions peculiar to the fuel oxygenates. SW846 Methods 8015D and 5021A have become official promulgated USEPA Methods.

Vapor Sampling and Analysis

From the earliest days at Microseeps, the sampling and analysis of vapors has been a prominent service offering.  Methods for the use of soil gas as an assessment tool for volatile organics were developed using thousands of samples at the Savannah River Site in the late '80's and was later applied to the evaluation of hundreds of vapor extraction remedial systems over the last decade. Microseeps has developed a vapor sampling method that is superior to the use of Tedlar bags and comparable to, but much cheaper than the use of Summa cannisters. Recently, Microseeps has applied these methods to soil gas projects related to vapor intrusion pathways.
