NORTHERN LAKE SERVICE INC.

Northern Lake Service Inc. specializes in analytical chemistry and environmental sample analysis for federal regulatory and research programs. The company provides laboratory services supporting the detection and quantification of emerging contaminants, including per- and polyfluoroalkyl substances (PFAS), in complex environmental matrices such as water, soil, and landfill leachate. Their technical expertise includes method development and validation for Unregulated Contaminant Monitoring Rule (UCMR 5) analytes, compliance testing under EPA guidelines, and precision sample preparation for trace-level contaminant analysis. The firm demonstrates deep proficiency in chromatographic techniques, mass spectrometry, and quality assurance protocols required for high-stakes environmental monitoring programs. The contractor maintains a consistent relationship with the Environmental Protection Agency, delivering critical laboratory support for UCMR 5 compliance and contaminant surveillance initiatives. They also serve the Department of Agriculture on landfill sampling projects and the Department of the Interior on PFAS characterization efforts, indicating a strong alignment with federal environmental protection and natural resource management missions. These engagements reflect a pattern of trusted, mission-critical laboratory services for agencies requiring defensible, auditable data for regulatory decision-making. Northern Lake Service Inc. operates primarily under NAICS 541380, focusing on testing laboratories and services for environmental contaminants, with supplementary experience in pesticide and agricultural chemical analysis under NAICS 325320. This positions them as a niche provider in environmental analytical services, particularly for emerging contaminants and regulated substances impacting water quality and land use. Their work supports environmental compliance, risk assessment, and stewardship programs across federal land and water management sectors. The company is structured as a small business (2L) with no federal certifications on record. Based in Crandon, Wisconsin, they serve as a regional provider with national relevance in environmental testing, leveraging geographic proximity to Great Lakes and agricultural watersheds to support targeted federal sampling programs. Their operational focus remains on precision, regulatory adherence, and data integrity in high-sensitivity analytical environments.
