JOHNSTON, CLIFFORD T

Clifford T. Johnston specializes in scientific and technical consulting focused on analytical methods for environmental and occupational health applications, particularly in the characterization of respirable mine dust. Their work centers on enhancing the precision and efficiency of rapid quartz analysis—a critical technique for monitoring airborne crystalline silica, a known occupational hazard. This involves the development and refinement of spectroscopic, chemical, or instrumental protocols to improve detection limits, data reproducibility, and field-deployable analysis workflows. The contractor’s technical expertise lies in analytical chemistry, mineralogical quantification, and dust sampling methodology, with a demonstrated focus on translating laboratory innovations into actionable field protocols for regulatory and safety compliance. The contractor has delivered services to the Department of Health and Human Services, specifically supporting public health initiatives related to occupational exposure standards and mine safety research. This engagement suggests a niche alignment with agencies overseeing workplace health surveillance, particularly those under the Centers for Disease Control and Prevention or the National Institute for Occupational Safety and Health. The nature of the work implies a consultative, research-support role rather than large-scale program management, emphasizing methodological rigor and technical validation. The primary NAICS code, 541690, reflects a focus on specialized scientific consulting that bridges laboratory analysis and regulatory application. This positions the contractor in the environmental health and industrial hygiene sector, serving federal research and compliance missions requiring precise analytical validation. Their market niche is defined by technical depth in mineral analysis rather than broad environmental consulting. As a sole proprietorship (Entity Structure 2J), the contractor operates with agility and direct technical oversight. With no formal government certifications listed, their credibility stems from demonstrated technical competence in niche analytical domains. Based on available data, their operational base is in West Lafayette, Indiana, with a focused, research-driven presence in the federal health and safety contracting space.
