This sealed‑bid contract requires the City of Worcester to purchase blended liquid phosphate for corrosion inhibition in its water‑filtration plant. The City estimates a need of roughly 200,000 lb over a one‑year period, with deliveries to a bulk‑storage tank (max 4,500 gal per shipment) and a 14‑day delivery window after purchase order issuance. Vendors must supply a product meeting EPA potable‑water standards and NSF‑60 certification, provide a one‑liter sample within 7 days of notification, and furnish third‑party lab test reports for a full suite of chemical parameters. The award went to Chemrite, which offered a unit price of $1.184 per pound; a $500 chemical conversion fee is also assessed. The contract is a unit‑price, full‑open‑competition solicitation with an optional two‑year renewal clause.
