چکیده

The principal sources and pathways of pharmaceutical and personal product (PPCP) compounds within an urban drainage system are identified with combined sewer discharges from households and infiltration from landfill/land sludge applications constituting major routeways. Illicit connections, sewer exfiltration and reclaimed domestic wastewaters comprise potentially significant other contaminant sources. Dilution ratios during wet weather events provide reasonable safety factors although seasonal and climate change effects can exacerbate PPCP impacts on receiving waterbodies. DWF dilution patterns for a sewage treatment works in N London are described together with exfiltration impacts from a trunk sewer. The study stresses the ubiquity of PPCP compounds in the urban aquatic environment and the difficulties of predicting cause-effect relations for the typical pollution “cocktail” associated with urban runoff discharges.

In this paper we describe CO2-PENS, a comprehensive system-level computational model for performance assessment of geologic sequestration of CO2. CO2-PENS is designed to perform probabilistic simulations of CO2 capture, transport and injection in different geologic reservoirs. Additionally, the long-term fate of CO2 injected in geologic formations, including

As the stress on urban water systems from climate change impacts, population growth and resource limitations continues to grow, the need to transition to sustainable urban water management is being increasingly acknowledged. However, understanding of how strategic planning should be made operational to enable this transition is limited, as the links between strategic action and the processes of...

Hospital effluents can potentially increase the concentration of emerging pollutants in the influent of wastewater treatment plants (WWTP) and receiving water bodies. This paper presents a hydraulic model that predicts the transport of selected pharmaceuticals and personal care products (PPCP) in a municipal sewer system section of Oslo, Norway. The sewer section additionally collects sewage fr...

Harvesting stormwater from urban catchments provides a supplementary water resource and, due to the physical abstraction of polluted water, also leads to environmental benefits. These benefits include the reduction of frequent ecosystem disturbance during small storms and less waterway erosion; hydrological impacts which are currently addressed by WSUD guidelines for stormwater detention. Altho...

Local-scale heterogeneity in natural aquifers plays a key role in solute mixing and chemical reactions. The incorporation of this scale of heterogeneity in traditional grid-based methods is difficult because of large computational costs and because of their poor accuracy in the advective-dominated transport found in most practical problems. Particle methods are an attractive alternative to simu...
