A remote electro-optical sensor (REOS) system permits early detection of algal blooms by continuously monitoring photosynthetic rates and other parameters in a distribution reservoir. A fish monitoring system utilizes abnormal reactions of fish as an early warning system of accidental or intentional contamination. No significant levels of byproducts were found in the use of Advanced Oxidation Processes (AOP), ozone and hydrogen peroxide, to remove trichloroethylene and tetrachloroethylene from contaminated groundwater supplies. Finally, corrosion studies show that the effectiveness of some treatment chemicals is highly dependent upon the dosage of the chemical used.
