. , ANON. . . provide related rainfall data with con- sideration of variation in int~nsity and location; ana to provide data showing the effects of progressive ur- banisation on flood peaks and volume. Six storm perio~s were selected for de- tailed analysis. The analysl!:'s for these storms incluoe a tabulation of incremental rainfall and discharge data, as well as hydrographs and mass curves. 1971: .Urban runoff in Lake County, Illinois.. In, Report to the Governor and the 77th Genernl Assembly, Vol.II - supporting studies. State of Illinois, Lake Michigan and Adjoining Land Study Commission; p73-101. Key words: urbanisation; biochemical oxygen demand; suspended solids; phosphorus compounds; urban runoff; sewage treatment. An attempt is made to quantify the am- ount of various pollutants which may teach Lake Michigan as a result of ru- noff from urban areas in tnke County, Illinois and to compare these quanti- ties with those which reach th~ lake in efflu~nts from sewage treatment plants in the same area. Various complex in- terre1atio~ships between runoff and sewage tre~tmcnt plants with r~gard to storm water are outlined. Physical factors - geography, 9recipitation, and land use - are described together with a summary of ~xisting sewage treatment practices. Sufficient data waS avail- able to compose two parameters, BOD and suspended solids. It was estimated that runoff usually accounted for ap- proximately 80 ?ercent of the total suspended solids and 12 gerccnt of the total BOD released to Lake Michigan, the remainder coming from sewage tr~at- ment plant discharges. However, during periodS of rainfall, the percentag~ of BOO resulting from runoff is greatly reduced. It is also concluded that ac- cepted figures for the quantity of phosphate contributed by urban runoff to l~k~ Michigan appears to be signifi- cantly low. ANON. 1971: "Storm ....ater quality..

This is a synopsis of a report by E. B. Bryan at the Water Resources Re- search Institute of the University of North Carolina which inv~stigated the "Ouality of Storm W3ter Drainage from Urban Areas in North Carolina". This project was undertak~n to evaluate the quality ch~racteristics of storm water runoff from 0 1.67 square mile drainage b3sin within the city of Durham, North Carolina. Parameters selected for rou- tine examination included total solids, volatile total solids, 000, COD, Chlo- ride, soluble phosphate, faecal coli- form counts, and lead. Flows were sam- ANON.

The former Health Committee of the City of Birmingham, now the Environm~ntal Services Committee, set up a special- ised unit within the Environmental De- partment to pay special attention to pollution. One of the particular ac- tivities of this unit was th~ d~v~lop- ment of a metal survey, part of w~ich involved the samplinq of dust from roads, gutters, school playgrounds, houses both inside an~ outside ann from some co~m~rcial premises. Nearly 5~0~ samples h~ve been t~k~n to d3t~ [thought to be more than in any other city in Europe) and h~ve been an~lysed for lead and a proportion of th~ sam- ples for oth~r metals.

The American City and County, Vol.91(10); pSI-53. Key words: storm runoff: runoff: flood control: watershed management: urban urban lakes; dri'inag"". New trends in storm water are dis- cussed, with particular emphasis on de- tention, long-term eaual isation, ann natural drainage. The objective of these solutions is to attenuate both peak and local short-term runoff ~nd to teduce major facilities investments re- quired for protecting against flood ha- tards in the low~r portion of a drain- ~ge basin. The initial planning for a residential subdivision should begin with a study of the total dr~inage areas, with th~ major components of the system (streams, larqe depressions, lakes, nod ponos) being located for an assessment of th~ir storm water mp.nage- ment potential. During this phase, ex- isting plans for storm water management should be ass~ss~d both in terms of th~ effect of the subdivision drain~ge on basin-wide drnlnage and vice versa. Temporary storaje can be achieved using rooftop and parking lot ponding; while ponds, reservoirs, and str~am chann~ls provide permanent storage.
