. An investigation of the pollution con- centrations and loads from storm water runoff in an urban ar~a was conducted in Tulsa, O~lahoma. The scope of the project included: a field ass~ssment of the storm water pollution by Obtain- ing samples of the water resulting ftom precipitation and surface runoff from selected test areas within the metro- politan area; development of an ana- lytical procedure for correlation of storm water pollution with selectively defined variables of land uses, envi- ronmental conditions, drainage charac- teristics, and precipitation; and de- velopment of a plan for implementing remedial measures necessary to abate or control sources of pollution in an urban arca. Storm water runoff samples were collected from IS 'discrete' test areas in th~ Tulsa metropolitan area for laboratory analysis in terms of quality standards for BOD, COD, TOe, organic Kjeldahl nitrogen, soluble or- thophosphate, chloride, pH, solids, total coliform, faecal coliform, and faecal streptococcus pollutants. Selected land use parameters, environ- mental conditions, drain~g~ and precip- itation data, along with storm water pollution factors, provided input data lor functional relationships to enable assessment of 9ollution from storm water runoff. Reco~mendations were m~de for a plan of ~ction for prevent- ing and controlling storm water pol~u- tion from urban areas. . . . f .

The conversion of land from rural to urban use results in a decrease in sur- face permeability and a marked increase in freshwater runoff to receiving wa- ters. This incre~sed runoff has the following effects; Cl) Strcllm chanm~ls become erod~d, widened and unst~b]e ano stream ecology changes. (2) Flooding' occurs aore frequently as the land is unable to store peak rainfall and re- lease it gradually after the peak of the storm. (3) Ground water b~comes depleted as w~ter runs off impermeable surfaces instead of sOuking into th~ ground. (4) Possible reduction of bGlse flow of the stream in periods of low rainfall due to decreased jnfiltr~tion to. ground water stor~g<;t.
