Ground Water / Surface Water / Non-Potable Water
With more than 50 years of environmental testing experience, Eurofins offers a comprehensive scope of analytical testing for non-potable water samples. Our extensive experience analyzing NPDES samples, monitoring wells, process and flowback water samples, surface water samples, and marine water samples ensures that your regulatory and project requirements will be satisfied. Methodologies offered include EPA, SW-846, Standard Methods, and ASTM. We also offer a number of specialty services including customized method development.
Soil and surface water
Remedial investigations are supported at Eurofins through a number of different methods. We routinely run GC/MS Volatiles by SW-846 8260B using methanol (high-level) or sodium bisulfate (low-level) preservation using EnCore soil samplers. We have extensive experience in hydrocarbon analyses, testing for PAHs by SW-846 8270C and other statespecific methods such as MA VPH/EPH.
Selective Ion Monitoring (SIM) is employed to meet lower action levels for PAH compounds. By monitoring a single ion within a specific retention time window, we are able to detect a lower mass of the target analyte. The ability to use SIM on these ecological matrices is based on the cleanups that we are able to do (GPC, in particular). Several cleanup techniques are utilized to remove matrix interferences that affect the reporting limits. The cleanups allow us to better differentiate the target ions from the matrix.
PCBs/Aroclors are identified by running SW-846 8082. Our recent MDL studies have shown we can meet most risk-based goals.
Soil samples to be analyzed for metals are prepared in accordance with SW-846 3050B acid digestion (a technique that allows the sample to dissolve completely and works very well) or SW-846 3052 microwave-assisted acid digestion. Water samples are digested using SW-846 3005A. Interferences found in brackish estuaries, such as the presence of chloride, sodium and TDS affect turnaround time and recoveries.
Eurofins is a pioneer in the analysis of wastewater for demonstrating compliance with wastewater permit requirements. Eurofins has extensive experience performing wastewater monitoring for the National Pollution Discharge Elimination System (NPDES) meeting the program requirements as administered in the states of Pennsylvania, New Jersey, New York, Delaware and Maryland for 40 CFR Part 136.
Eurofins's technical staff will review your permit and develop a monitoring program based on your needs and permit requirements. Data from monitoring events is clearly reported. Permit exceedances are flagged for easy recognition and presented in a timely manner to enable the client to initiate corrective action if necessary.
Eurofins field ervices staff regularly performs wastewater sampling and is well versed in developing sampling schemes to comply with client specific permit requirements. Eurofins also applies wastewater monitoring technology to the sampling and analysis of surface waters and stormwater to develop data for comparison with Federal and State standards.
