History of Nalco Water
- Founded: 1928
- Founders: Herbert G. Kerr (predecessor business)
- Acquired by Ecolab Inc.: 2011
The Nalco business traces to 1928, when Herbert G. Kerr founded a Chicago water treatment company that became one of the pioneering industrial water management firms. Nalco Chemical Company grew through the twentieth century into the leading US industrial water treater, serving power plants, refineries, steel mills, and manufacturers.
The company went public, was acquired by Suez in 1999, and was spun out again as an independent Nalco Holding Company in 2003. As an independent public company it remained the industrial water treatment leader until Ecolab's $5.4 billion acquisition in 2011.
Under Ecolab, the Nalco brand was maintained as Nalco Water, the identity for the industrial water treatment business. The 2013 acquisition of Champion Technologies added oilfield chemicals, merged into the Nalco operation as Nalco Champion for the energy segment before being fully integrated.
The brand has evolved from basic water treatment chemicals to integrated water and process management, incorporating the parent's digital monitoring, automation, and AI capabilities into offerings for data center cooling, microelectronics, and advanced manufacturing.

Nalco Water Recalls & Controversies
As an industrial water treatment brand, Nalco Water's issues are operational and environmental rather than product recalls.
Oilfield chemical scrutiny: The energy services business has faced scrutiny over hydraulic fracturing water treatment, though its role is treatment and management rather than extraction.
Chemical handling: Industrial water treatment chemicals carry handling and discharge regulations, with compliance managed through standard industrial protocols and periodic regulatory attention.
Historical ownership complexity: The brand's passage through Suez ownership and multiple ownership transitions created brand identity questions resolved by Ecolab maintaining the Nalco name as the industrial water standard.
