The Federal Bureau of Prisons is conducting market research through a Sources Sought Notice to identify qualified contractors for a Blanket Purchase Agreement supporting water treatment chemicals, testing, monitoring, reporting, and related services at BOP correctional institutions nationwide. The contractor would supply personnel, chemicals, testing equipment, laboratory services, transportation, reporting systems, and technical support for boiler, chiller, cooling tower, and domestic water systems, including Legionella and other domestic water testing, compliance support, and a secure online reporting portal. Required services include monthly boiler testing, seasonal chiller-loop and cooling-tower testing, quarterly domestic water/Legionella testing at active inmate housing institutions, corrective recommendations, trend analysis, and monthly/quarterly reporting. Contractors must be able to implement treatment recommendations and supply required chemicals within 15 calendar days of test results and demonstrate nationwide geographic coverage and timely service across dispersed institutions. Respondents should identify planned subcontracting arrangements and prime-contractor experience, and the government is assessing small business set-aside possibilities.
