COMMERCIAL TESTING LABORATORY INC

Commercial Testing Laboratory Inc. specializes in environmental water quality testing and analytical services for federal land and water resource management programs. The company delivers precision laboratory analysis for contaminants, microbiological parameters, and chemical constituents in surface and groundwater samples, supporting compliance with federal water standards and ecological monitoring protocols. Their technical expertise includes method validation, sample chain-of-custody management, QA/QC documentation, and data reporting aligned with EPA and ASTM protocols. A key differentiator is their consistent, repeatable execution of field-to-lab workflows under time-sensitive, mission-critical conditions, particularly in remote national park and scenic riverway environments. The contractor maintains a deep, sustained relationship with the Department of the Interior, consistently supporting field operations at the St. Croix National Scenic Riverway and other SACN-managed sites. Their work directly enables resource protection, regulatory reporting, and public health safeguards through reliable, defensible analytical data. The agency relies on them for recurring, on-demand water testing services that inform environmental stewardship decisions across protected lands. Commercial Testing Laboratory Inc. operates exclusively within NAICS 541380, focusing on environmental testing laboratories and services. This positions them as a niche provider of field-deployable analytical capabilities for federal natural resource agencies, with an emphasis on hydrologic monitoring and compliance-driven data collection. They serve the environmental science and conservation vertical, filling a critical gap between field sampling and regulatory-grade laboratory analysis. As a small business structured as a 2L entity based in Colfax, Wisconsin, the company maintains a focused geographic footprint aligned with federal land management operations. While currently holding no formal government certifications, their proven track record of delivering high-integrity testing services under blanket purchase agreements demonstrates operational reliability and institutional trust within the federal environmental services market.
