This is a chemical specifications document for the Washington Suburban Sanitary Commission (WSSC) in Maryland, which outlines treatment chemical parameters for water treatment services across eleven facilities. The document details three primary chemical treatment programs: a Closed System Nitrite Program maintaining pH levels of 9-10 with nitrite concentrations between 500-1000 ppm; a Closed System Sulfite Program with pH 9-10 and sulfite levels at 80 ppm with maximum total dissolved solids of 3500; and a Steam Boiler Program with pH 9-11 requiring specific ranges for sulfite (30-60 ppm), phosphate alkalinity (300-400 ppm), alkalinity (400-600 ppm), and phosphate (30-60 ppm) with iron monitoring. The WSSC issued a solicitation for sealed responses due by 2:00 pm on Monday, August 3, 2026, through their eProcurement Portal at https://procurement.opengov.com/portal/wsscwater, with late submissions not accepted.

The document serves as a technical specification guide for the selected contractor who will be responsible for furnishing all supervision, labor, equipment, materials, chemicals, tools, and related services necessary to maintain these designated systems across WSSC's facilities. The chemical parameters specified represent industry-standard water treatment protocols designed to prevent corrosion, scaling, and biological growth in HVAC and biosolids systems while maintaining system efficiency and longevity.
