“…Potential sources may include sewage overflows (34), leaking septic systems, and birds occupying the beach (28,30,46,50). Rainfall and onshore winds can cause a dramatic increase in concentration and can exacerbate the contamination problem (15,56). Bacterial counts in water eventually fall to levels considered to be safe for swimming; however, many indicators remain in the sediment and adjacent beach sand (17,36) and can impact beach water quality at a later time.…”

Swimming advisories due to excessive Escherichia coli concentrations are common at 63rd Street Beach, Chicago, Ill. An intensive study was undertaken to characterize the source and fate of E. coli in beach water and sand at the beach. From April through September 2000, water and sand samples were collected daily or twice daily at two depths on three consecutive days per week (water samples, n ‫؍‬ 1,747; sand samples, n ‫؍‬ 858); hydrometeorological conditions and bird and bather distributions were also recorded. E. coli concentrations in sand and water were significantly correlated, with the highest concentration being found in foreshore sand, followed by those in submerged sediment and water of increasing depth. Gull contributions to E. coli densities in sand and water were most apparent on the day following gull activity in a given area. E. coli recolonized newly placed foreshore sand within 2 weeks. Analysis of variance, correlation, cluster analyses, concentration gradients, temporal-spatial distribution, demographic patterns, and DNA fingerprinting suggest that E. coli may be able to sustain population density in temperate beach sand during summer months without external inputs. This research presents evidence that foreshore beach sand (i) plays a major role in bacterial lake water quality, (ii) is an important non-point source of E. coli to lake water rather than a net sink, (iii) may be environmentally, and perhaps hygienically, problematic, and (iv) is possibly capable of supporting an autochthonous, high density of indicator bacteria for sustained periods, independent of lake, human, or animal input.

“…Muitos estudos enfocam a importância dos fatores ambientais na dinâmica dessas bactérias indicadoras de poluição fecal na água, tanto por óbvias preocupações de saúde pública como pelo interesse de avaliar a magnitude e natureza do declínio dos coliformes no ambiente CROWTHER et al, 2001;NOBLE et al, 2004). Os resultados destas investigações sugerem o envolvimento de diversos fatores individuais influenciando, com magnitude variada de importância, a sobrevivência e dispersão desses micro-organismos (ALKAN et al, 1995).…”

“…As condições climáticas como chuva e vento (CROWTHER et al, 2001, GABUTTI et al, 2004, e movimentos da maré (MILL et al, 2006) são alguns dos parâmetros que provocam a dispersão desses micro--organismos no ambiente e consequentemente influenciam na sua abundância.…”

This study is focused on water quality of Melen River (Turkey) and evaluation of 26 physical and chemical pollution data obtained five monitoring stations during the period [1995][1996][1997][1998][1999][2000][2001][2002][2003][2004][2005][2006]. It presents the application of multivariate statistical methods to the data set, namely, principal component and factor analysis (PCA/FA), multiple regression analysis (MRA) and discriminant analysis (DA). The PCA/FA was employed to evaluate the high-low flow periods correlations of water quality parameters, while the principal factor analysis technique was used to extract the parameters that are most important in assessing high-low flow periods variations of river water quality. Latent factors were identified as responsible for data structure explaining 72-97% of the total variance of the each data sets. PCA/FA was supported with multiple regression analysis to determine the most important parameter in each factor. It examines the relation between a single dependent variable and a set of independent variables to best represent the relation in the each factor. Obtained important parameters provided us to determine the major pollution sources in Melen River Basin. So factors are conditionally named soil structure and erosion, domestic, municipal and industrial effluents, agricultural activities (fertilizer, irrigation water and livestock wastes), atmospheric deposition and seasonal effects factors. DA applied the data set to obtain the parameters responsible for temporal and spatial variations. Assessment of high-low flow period changes in surface water quality is an important aspect for evaluating temporal and spatial variations of river pollution. The aim of this study is illustration the usefulness of multivariate statistical analysis for evaluation of complex data sets, in Melen River water quality assessment identification of factors and pollution sources, for effective water quality management determination the spatial and temporal variations in water quality.
