MATRIX SCIENCES INTERNATIONAL INC

Matrix Sciences International Inc. specializes in environmental analytical services for low-level selenium detection in complex aquatic and sediment matrices, delivering precision laboratory testing to support federal water quality monitoring programs. The contractor provides high-sensitivity analytical workflows for trace contaminant characterization in groundwater, sediment, and bypass water samples, utilizing advanced instrumentation and validated methods compliant with EPA and state regulatory standards. Their technical expertise includes sample preparation, method validation, quality assurance/quality control (QA/QC) protocols, and data reporting for environmental baseline studies and long-term monitoring initiatives, particularly in sensitive ecosystems such as grassland wetlands and riverine systems. A key differentiator is their consistent execution of complex, multi-site, longitudinal sampling programs requiring strict chain-of-custody and low-detection-limit accuracy under demanding field-to-lab conditions. The company maintains a sustained relationship with the Department of the Interior, primarily supporting hydrologic and ecological monitoring projects across federal land and water management programs. Their work directly informs environmental assessments for infrastructure projects, wildlife habitat protection, and water resource compliance, often in collaboration with regional field offices and state partners such as CDFW-R4. This recurring engagement reflects deep institutional trust in their ability to deliver technically rigorous, audit-ready data under evolving regulatory frameworks. Matrix Sciences operates exclusively within the Testing Laboratories and Services NAICS category (541380), positioning itself as a niche provider of environmental analytical services for federal natural resource agencies. Their market focus is on trace contaminant analysis in environmental media, with specialization in selenium speciation and low-concentration detection in complex matrices—a critical capability for agencies managing legacy contamination and ecosystem health. As a small business structured as a 2L entity based in Chicago, Illinois, Matrix Sciences International Inc. operates without federal certifications but maintains a focused, mission-aligned presence in the federal environmental testing market, delivering specialized lab services to agencies requiring high-precision environmental data.
