Independent Third Party Data Validation

HSW Engineering, Inc. provides independent third-party validation of environmental data (groundwater, soil, surface water, and sediment samples and associated Quality Assurance /Quality Control samples) and generates QCSRs (Quality Control Summary Reports) for a variety of military sites throughout the country.  

Work is performed as a subcontracted service to clients, who are the prime contractors with the U.S. Army Corps of Engineers.  HSW has been working with one of the clients for roughly 10 years.  HSW currently has three active projects, two of which involve regular on-going monitoring of groundwater by SW-846 methods and require QCSRs written each year.  For a large project currently in progress, HSW worked with the primary contract laboratory to establish an ADR (Automated Data Review) project library based on project objectives, DoD QSM Ver 4.1 requirements for accuracy and precision, and the laboratory’s empirical quality control limits.  The laboratory is providing ADR Level 2a EDDs (Electronic Data Deliverables) as well as full EPA Level IV deliverables for over 200 soil samples and over 70 groundwater samples, each of which is being analyzed by SW-846 methods for volatile organic compounds, semivolatile organic compounds, metals, and petroleum hydrocarbons.  All of the EDDs are being processed through ADR.  The expanded deliverables are being reviewed 100% for completeness, with a representative 10% of these expanded deliverables undergoing manual validation.
