anthropogenic alterations have affected urban hydrology in india and have generated a wide range of hydrological problems. such alterations include increase in directly-connected impervious cover thus reducing natural groundwater recharge. in the past urban runoff was largely viewed as a nuisance, but within the new paradigm of sustainability, this water is recognized as a potential resource. t...

Artificial recharge of urban aquifers with stormwater has been used extensively in urban areas to dispose of stormwater and compensate for reduced groundwater recharge. However, stormwater-derived sediments accumulating in infiltration beds may act as a source of dissolved contaminants for groundwater. Concentrations of hydrocarbons, heavy metals, nutrients and dissolved oxygen (DO) were monito...

In urban and suburban areas, stormwater runoff is a primary stressor on surface waters. Conventional urban stormwater drainage systems often route runoff directly to streams and rivers, thus exacerbating pollutant inputs and hydrologic disturbance, and resulting in the degradation of ecosystem structure and function. Decentralized stormwater management tools, such as low impact development (LID...

The objective of the Parafield Aquifer Storage Transfer and Recovery research project in South Australia is to determine whether stormwater from an urban catchment that is treated in a constructed wetland and stored in an initially brackish aquifer before recovery can meet potable water standards. The water produced by the stormwater harvesting system, which included a constructed wetland, was ...

Urbanisation and the subsequent increase in impervious land use generate increased urban stormwater which can be recycled viamanaged aquifer recharge (MAR) to supplement more traditional surface or ground water supplies. This paper compares the quality of stormwater from two urban catchments in South Australia to assess the risks, in accordance with the Australian Guidelines for Water Recycling...

The University of Minnesota is committed to the policy that all persons shall have equal Acknowledgements The Minnesota Pollution Control Agency (MPCA) provided funding for this review. The involvement of the project manager from the MPCA, Bruce Wilson, was greatly appreciated. Executive Summary Recently, there has been an increased interest in the use of infiltration as a method of managing st...

A quantitative microbial risk assessment (QMRA) was performed at four managed aquifer recharge (MAR) sites (Australia, South Africa, Belgium, Mexico) where reclaimed wastewater and stormwater is recycled via aquifers for drinking water supplies, using the same risk-based approach that is used for public water supplies. For each of the sites, the aquifer treatment barrier was assessed for its lo...

Abstract Urbanization alters the flow regime of streams, including increasing frequency and magnitude storm flows, along with reducing baseflows. An increasingly common management strategy is stormwater infiltration, which thought to reduce surface runoff recharge groundwater thus restore lost baseflows streams. Recent research has pointed considerable uncertainty on fate infiltrated stormwater...
