Average total dissolved sol- <br />ids and nitrates as well as the average <br />pH value of storm runoff are within the <br />USPHS standards for drinking water, <br />while solids concentr~tions and total <br />alkalinity concentrations are in the <br />r~nge of those founn in raw sewage in- <br />fluent.

The <br />drainage basin selected has an area of <br />1.67 square ~iles an~ is in th~ upper <br />portion of the Caoe River basin of <br />North Carolina. Re~idential, commer- <br />cial and industrial rctivities on the <br />selected bnsin are repres~ntative of <br />the urban land use pattern in North <br />Carolina cities and towns. Durincr the <br />first year a gauginq jnd sa~p1ing sta- <br />tion was installed on the outlet of the <br />major basin. SHmpling and analyses <br />w~re initiated to charact~rise the <br />qu~lity of water draining from the <br />basin and its two major constitu0nt ba- <br />sins. In the second year, the major <br />basin was divid~d into a nu~ber of sub- <br />sidiary basins to characteris~ th~ <br />quality of water draining fro~ P2ch <br />sub-b~sin nnd att~mpt correl~tion of <br />its qualities with land use. <br /> <br />. <br /> <br />, <br /> <br />BRYAN, E.H. 1971: hUrban storm w'ter oual- <br />ity and its imp~ct on the r~c~ivino <br />system..
