The pH values above and below concrete structures in streams on nine active construction projects throughout the state were determined. It was concluded that for streams with flow rates of 0.3 to 111.25 cfs (0.01 to 3.2 cubic meter/see) the variations in the pH levels of the water above and below the concrete structures were within; the acceptable EPA limit of 0.5 pH unit. It was concluded that cured concrete structures in live streams do not significantly affect the pH level of the water.
