Radon Measurement Professionals and Lead-Based Inspectors and Risk Assessor Service

The Chelsea Housing Authority in Chelsea, Massachusetts is seeking independent third-party professional services to identify and address environmental health hazards in residential properties. The agency requires these services to mitigate risks to occupant health, specifically focusing on lead exposure, radon, and other housing-based conditions. The selected contractor must perform all assessments without any conflict of interest regarding subsequent rehabilitation or abatement activities. The scope of work requires radon testing in all residential units participating in the program, which includes the placement, retrieval, and analysis of testing devices. The agency allows the use of either passive devices or continuous radon monitors depending on site conditions, provided all testing follows current American Association of Radon Scientists and Technologists standards. The contractor must deliver complete radon testing documentation for each unit, including the test results, an interpretation of the findings, and the identification of any elevated radon levels that require mitigation. The agency also requires a full range of lead-based paint inspection and risk assessment services to identify and document lead hazards. This portion of the work covers soil sampling, environmental pathway analysis, dust wipe sampling, and clearance testing. The contractor must perform these services both onsite in Chelsea, Massachusetts and offsite at their own facilities, ensuring compliance with all applicable federal, state, and local requirements. Eligibility is restricted to onshore organizations based in the United States. The agency is looking for proposals to determine the budget for this project. Bidders must submit any questions regarding this opportunity no later than July 8, 2026. Final responses may be submitted digitally via email or through the online portal.
