Abstract
A water integrity control and disinfection method and system that measures key water parameters and can diagnose water integrity instability trends that result in loss of water integrity. Relevant water parameters that are predictive of water integrity such as cell null value as measured by in-line colorimetry provide early warning and prediction of problematic trends in the water integrity so that the system can pro-actively respond appropriately and prevent, mitigate or reverse the instability trend and maintain microbiological control of the water supply.

Abstract
A system and method for controlling microbiological growth in a water system and premise plumbing system which uses stabilized hydrogen peroxide as a disinfectant and maintains water energy matrix control. Maintenance of stable hydrogen peroxide residual in the system in combination with active temperature monitoring enables better control of the water energy matrix and reduction of hot water temperature while maintaining microbiological control.

Abstract
An apparatus and method for measuring hydrogen peroxide concentration in water to an accuracy of 0.1 ppm comprises a colorimetric assay method to determine hydrogen peroxide concentration. The assay is monitored spectophotometrically at a desired wavelength. Each sample is corrected relative to a control sample and hydrogen peroxide concentration determined with respect to a standard curve.
