This book was released on 1996 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Raisin River watershed, located approximately 130 kilometres east of Ottawa, is the site of an environmental project examining the groundwater quality and contamination potential of a fractured bedrock aquifer in an agricultural basin discharging to the St. Lawrence River. Groundwater quality was monitored in five tile drains, four piezometers, and thirteen domestic wells over a period of 14 months (May-94 to June-95). Temporal variations in total dissolved solids (TDS), water level and major element concentrations, as well as fluctuations in dissolved organic carbon (DOC), $\delta\sp2$H and $\delta\sp $C were used to distinguish between regionally recharged groundwaters and recharge occurring by local infiltration through agricultural fields. Nitrate, agricultural pesticides, and heavy metals were analyzed as the principal components of groundwater quality. Water level, dissolved solids, $\delta\sp2$H, and $\rm\delta\sp C\sb{DIC}$ fluctuated according to seasonal change. Springtime showed high water levels coupled with depleted $\delta\sp2$H values. In addition, nitrate and DOC values were elevated due to local infiltration through the soil zone into the bedrock aquifer. The $\delta\sp $C values show that recharge contributions from (i) bedrock recharge areas, and (ii) infiltration through cultivated fields, vary on a seasonal basis. Spring and summer periods are dominated by recharge through cultivated fields where $\delta\sp $C values are governed by infiltration of C$\sb4$ plant (corn) carbon. Contributions of local recharge during the fall and winter months are reduced. The watershed's susceptibility to groundwater contamination is considered high since the aquifer responds to seasonal climatic variations. The mean residence time of these groundwaters is in the range of several months, based on cross-correlations between air temperature and $\delta\sp2$ values of Raisin River waters. The most potentially harmful times of year occur during rapid groundwater infiltration during the spring and periods of high precipitation. The effect of tile drains in diverting agro-contaminants to the Raisin River contributes to overall good bedrock groundwater quality as tile drainage effluent shows elevated concentrations of pesticides, nitrate, and trace metals.

This book was released on 2007 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban development has, historically, been more concerned with the hydraulic characteristics of the drainage systems and technological solutions for controlling floods and pollution than understanding the hydrological characteristics and sustainability of urban catchments. Given the complexity in evaluating the hydrologic behaviour of urban catchments, these systems remain poorly understood and an under-researched field of hydrogeology. Conventional models that solely concentrate on urban runoff as the primary cause of reduced natural recharge do not effectively deal with new sources or pathways of recharge created specifically by urbanization.The hydrologic cycle of Frenchman's Bay watershed, a 27 km2 highly urbanized catchment just east of Toronto, Ontario, Canada has undergone a fundamental change in the last 50 years due to increased urban cover. Isotopic hydrograph separation of groundwater and surface waters in stormflow showed that only about 15% of rainfall appears as overland flow and that groundwater accounts for 21% of the total stormflow. Furthermore, it was estimated that 35% of the total rainfall contributes to groundwater recharge.Analytical and numerical models were used to quantify and validate the elements of the urban water cycle. A modified soil moisture balance for the watershed highlighted the significance of localized recharge through preferential pathways. It was found that localized recharge through bypass flow has increased net recharge by about 36%. Moreover, infiltration of roof runoff and physical losses from water mains have essentially maintained urban recharge at preurban levels. Numerical simulations verified increased recharge that occurs following urbanization through onsite infiltration of roof runoff and bypass flow.A chloride mass balance revealed that approximately 50% of road salt applied to the catchment is stored in the shallow subsurface. The presence of oxygen-18 depleted groundwaters with higher bicarbonate concentrations in the most urbanized part of the catchment further substantiates the existence of a highly responsive urban aquifer.The findings of this study have important implications in our understanding of the complex behaviour of urban aquifers including groundwater-surface water interactions and contaminant flow paths.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundwater is an important source of baseflow. Baseflow supports minimum flows and living area through dry periods, and moderates surface water temperature. The reductions in baseflow after urbanization can cause degradation of the stream ecosystem. The purpose of this study was to investigate the groundwater-surface water interaction and thermal regime of Clythe Creek, Guelph to illustrate the importance of groundwater/streamflow interaction in determining the health of a stream ecosystem. Piezometers were used to quantify vertical and lateral groundwater flow direction, and surface water temperature measurements were used to characterize and quantify the thermal regime. Groundwater-surface water interaction varied both temporally and spatially between the two geomorphic units. Average summer surface water temperatures were consistently cooler in the downstream portion of the study reach. The importance of groundwater-surface water interactions in supporting stream ecosystems was concluded from this study, and restoration strategies to address threats from urbanization were made.
