Neptune provides third-party Data Validation and Verification, and in particular Focused Data Validation and Usability Assessment. We can then evaluate the field and laboratory QA/QC results in conjunction with analytical data, including field conditions such as pH and redox chemistry, to understand where failed QC impacts the data. This can be especially important in human health and ecological risk assessment, where redox conditions may preclude risk even when metals are present. The results obtained for total and hexavalent chromium are one example where this is applied.

Our chemists have extensive background in routine and innovative methods, including MS/MS techniques. We are particularly adept at developing validation steps for these non-routine methods and have significant experience with analytical techniques used for hydraulic fracturing studies, including RSK 175, glycols, and non-target species. We provide expertise in data usability, where the initial validation may have resulted in qualification. The extent and impact of this qualification can be evaluated and communicated, and in many instances contractually non-compliant data are usable within reasonable limits.
