Quantity and quality of urban storm runoff in the Irondequoit Creek basin near Rochester, New York: Part 2,.Quality of storm runoff and atmospheric deposition, rainfall-runoff-quality modeling and potential of wetlands for sediment and nutrient retention

Storm runoff from four characteristic types of residential roofs and incident rainwater were monitored for 47 storm events over a six‐month period at Nacogdoches, Texas, to study water quality conditions for 20 element and four chemical variables. The total element concentration in storm runoff from each roof type was greater than that of rainwater in the open. Differences in element concentrations in storm runoff among the four roof types were statistically significant (α≤ 0.05) with the differences for the wood shingle roof being the greatest and that for terra cotta clay roof being the least. The median concentrations of four element variables exceeded the Texas surface water quality standards, while 12 variables exceeded the standards at least one time in all samples collected. Zinc concentrations violated the Standard ranging from 85.7 percent of the samples for the wood shingle roof to 66.0 percent for the composite shingle, the greatest exceedances of all 24 variables studied. Storm characteristics and gutter maintenance level had some effects on these water quality conditions. The study suggested that roof types can be important to water pollution management programs. More detailed studies on roof water quality in major municipalities are required.

The diagram below shows the percentage of the investigations for fiscal year 1987 in each of the broad categories of collection of hydrologic data, areal appraisals and interpretive studies, and research projects: COLLECTION OF HYDROLOGIC DATA RESEARCH PROJECTS AREAL APPRAISALS AND INTERPRETIVE STUDIES These investigations are directed toward obtaining the information needed by managers and planners for the solution or alleviation of water problems in New York. The investigations are supported by funds provided by State and local units of government and federal funds from the U.S. Geological Survey and other federal agencies (OFA program). About 80 percent of the federal funds contributed by the Geological Survey are used to match, on a 50-50 basis, the funds contributed by the State and other local units of government. In fiscal year 1987, the financial support for these programs in New York was about $7.3 million, which was distributed as follows:
