NIGP 88578: pH Control Chemicals: Caustic Soda, Lime, Muriatic Acid, Quicklime, Soda Ash, etc.

NIGP 88578, pH Control Chemicals: Caustic Soda, Lime, Muriatic Acid, Quicklime, Soda Ash, Etc. is an Item code under which state and local governments procure treatment chemicals for municipal water and wastewater facilities. Recent solicitations show this code drives demand for calcium oxide (quicklime, hydrated lime), liquid caustic soda, muriatic acid (hydrochloric acid), sodium hypochlorite, and specialized treatment compounds—all NSF-certified for potable and reclaimed water systems. Water treatment plants represent the dominant buyer segment, with secondary activity from pool and recreational facilities. Cities and regional water authorities issue the majority of opportunities, with occasional procurement from county utilities and school districts. Typical scopes include bulk delivery of 20–1,800 tons annually on firm pricing, with 72-hour delivery windows and comprehensive material documentation (Certificates of Analysis, Safety Data Sheets, NSF/AWWA certification). Sole-source procurements for proprietary equipment such as lime slaking systems and compatible replacement parts also fall under this code when tied to treatment chemical supply.

Recent activity spans the Southeast (Florida, Georgia), Southwest (Arizona, Utah), and Pacific Northwest (Oregon), with Florida jurisdictions showing the heaviest concentration. The City of Holly Hill, Florida posted sole-source notices for Chemco Systems LP lime slaking systems and related services and for Andritz Separation, Inc. replacement parts (October 2026).
