Are Sentinel water treatment chemicals really harmless to the environment?

In their concentrated form, Sentinel’s cleaners and inhibitors have been independently tested to be inherently and ultimately biodegradable according to OECD Guideline No. 302B (1992) “Inherent Biodegradability: Modified Zahn-Wellens/EMPA Test”, EEC Commission Directive 87/302/EEC and US EPA Fate, Transport and Transformation Test Guidelines OPPTS 835.3200. Consequently, the discharge of our products when diluted to recommended system water concentrations have negligible environmental impact.
