Water security and sustainability in urban India
The rapid growth of population combined with rising levels of consumption and pollution has increased water insecurity in urban India. The depleting water sources on the one hand, higher financial and technological costs to refine and transport water from far off sources on the other, leave limited possibilities to augment the water supply in the near future. Climate change may further adversely ...

CL#7 - In Situ BioLogix Application - Case Study
Site Information Dry cleaning solvents were found in the ground water at the former location of a dry cleaning facility at a commercial shopping center. Most of the mass of ground water contamination was located under a bank that was built over the former dry cleaners, restricting access for remediation. The PCE plume was estimated to be 30,000 square feet. The PCE concentration was greater than ...

Aquatic Ecosystem
An aquatic ecosystem is an ecosystem located in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems.[1] Continue reading the full article ...

Pellissippi Parkway Study
Summary: At the Pellissippi site the investigation concerned finding hidden voids underneath the highway. It is built on a location where numerous cave-ins have occurred over the years. The objective at this site was to determine if it was possible to find new voids in the subsurface which could be expected to cause more cave-ins. At this site the Dip-Dip method was used with a 56 ...

Designing robust water planning institutions in remote regions: a case of Georgina and Diamantina catchment in Australia
Several catchment-based water planning processes are currently underway in Australia, with the Water Reform Agreement of 1994 providing the legislative umbrella. This paper presents the results of a case study conducted in the joint catchment of the Diamantina and Georgina rivers, located in the remote central-west part of the state of Queensland. The paper investigates the new water planning ...

Four free surface algorithms for the 3D Navier–Stokes equations
Four algorithms are described for computing a steady free water surface with the solution of the three-dimensional (3D) Navier–Stokes equations. The numerical methods are used in hydraulic engineering cases, typically spillways and river modelling. The algorithms were tested against a laboratory experiment of a v-shaped broad-crested weir. The complex geometry of the weir introduced ...

Pb isotopes in drinking water: a new strategy for source detection of low Pb sources
Source detection of low concentrations of Pb in water, for instance less than 15 μg L-1, may require a new methodology as the tolerances of Pb in drinking water are further reduced. It appears that the isotope properties of Pb may aid discrimination among natural sources and anthropogenic sources, including some plumbing materials. Characteristic Pb isotope signatures in a typical rural water ...

Guarantee rate of freshwater in a river mouth intruded by saltwater with respect to the joint impact of runoff and tide
Saltwater intrusion is detrimental to water utilization. It is of vital significance to study the joint impact of runoff and tide on salinity and the risk of saltwater intrusion. To analyze the risk of saltwater intrusion, this paper proposes two concepts: critical runoff–tide level line and guarantee rate of freshwater. Taking Nandu River Estuary in China as a study case, a three-dimensional ...

Photodegradation of the antihistamine cetirizine in natural waters
The photodegradation rate of the anti‐histamine cetirizine (Zyrtec®) was investigated in various water matrices. The average observed first‐order photodegradation rate coefficient (kobs), obtained by linear regression of the logarithmic‐transformed cetirizine concentrations versus irradiation time in simulated sunlight, was 0.024 h−1 (n = 6; S.D. ± 0.004) in deionized water (DIW) corresponding ...

Diffuse pollution
Diffuse Pollution or Nonpoint source (NPS) pollution is water pollution affecting a water body from diffuse sources, such as polluted runoff from agricultural areas draining into a river, or wind-borne debris blowing out to sea. Nonpoint source pollution can be contrasted with point source pollution, where discharges occur to a body of water at a single location, such as discharges from a ...

Can Dowsing Rods Locate Water Supplies?
Finding water in the 21st century really isn’t all that difficult. We turn on the tap and out it streams, without so much as a second thought. However, it hasn’t always been that easy and – although we’re now blessed with a solid pipe network and other infrastructure that brings us what we need when we need it – in times past, civilisations had to rely on other ways ...
