NEILSON RESEARCH CORPORATION

Neilson Research Corporation specializes in environmental water testing and analytical laboratory services, delivering precise, field-deployed chemical and biological analyses for federal environmental compliance and public health initiatives. Their technical expertise encompasses a broad spectrum of water quality parameters including arsenic, coliform bacteria, BOD5, nitrates, nitrites, ammonia, phosphorus, TSS, synthetic organic compounds, and inorganic ions, utilizing advanced methodologies such as Gas Permeable Membrane (GPC) systems and Quanti-Tray technologies. The firm demonstrates a strong command of EPA-compliant protocols and field sampling logistics, with a focus on high-volume, multi-parameter testing in complex aquatic environments. Their differentiation lies in operational agility across remote and ecologically sensitive sites, enabling rapid, accurate data collection for regulatory decision-making and environmental monitoring programs. The company has delivered services to the Department of Defense and the Department of Agriculture, supporting mission-critical water quality assessments in military installations and forested watersheds. For DoD, they provide environmental compliance testing under blanket purchase agreements, while for USDA, they conduct forest-wide hydrological monitoring to safeguard watershed integrity and ecosystem health. Their engagement patterns suggest a consistent role as a trusted technical vendor for environmental stewardship and regulatory adherence in federal land and water management programs. Neilson Research operates primarily under NAICS 541380, which defines testing laboratories and services for environmental, chemical, and biological analysis. Their market positioning centers on niche environmental monitoring, particularly in hydrologic and ecological contexts where regulatory precision and field scalability are paramount. They serve as a specialized contractor for agencies requiring accredited, defensible water quality data beyond standard sampling protocols. As a small, privately held entity based in Medford, Oregon, Neilson Research Corporation maintains a focused, regionally grounded presence with no formal government certifications. Their operational footprint is defined by contract-driven field deployments rather than large-scale laboratory infrastructure, positioning them as a responsive, on-the-ground technical partner for federal environmental programs in the western U.S.
