Victorian Groundwater Management System Direct Input to ESdat
The Victorian groundwater management system (GMS) is a database of groundwater related data (for example groundwater, geology or chemistry data) across Victoria that is delivered quarterly by DVD from the Department of Sustainability and Environment to registered subscribers. The delivery of data from this system is often in a format that is time-consuming to extract, filter and output as ...

Offline Field Portal for Environmental Data
ESdat users have been asking for a long time, “when will the Field Portal work offline?” That date has finally arrived; the ESdat Field App has recently been released. The ESdat Field App is an upgrade of the Field Portal, offering all the same functionality and look and feel, but is further optimised for small screens and works offline. Features of the ESdat Field App include: • ...

Groundwater monitoring: what’s winter field work like?
Although the stimulation phase of the Newberry EGS Demonstration has come to a close, field work continues throughout the winter months on the volcano (brrr!). We’re currently collecting and analyzing groundwater samples in order to monitor any changes in the local groundwater system. This work is intended to make sure thestimulation hasn’t affected the quality of the groundwater high ...

Passive Groundwater Sampling – The Proven Alternative to Well Purging
By David Kaminski, Senior Vice President & Sandy Britt, Senior Hydrogeologist - QED Environmental Systems, Inc. Selecting groundwater sampling technology for any particular application can be challenging, as there is a wide range of technology available on the market, and some are far more effective than others. The traditional approach of pumping a well to remove “stagnant” ...

New science gauges potential to store CO2
A new method to assess the US's potential for storing carbon dioxide could lead to techniques for lessening the impacts of climate change, according to Secretary of the Interior Ken Salazar, who praised a U.S. Geological Survey report in an energy teleconference today. The USGS released the report to describe its methodology to assess the nation's potential for carbon sequestration--the ...

MOE presents: provincial water monitoring networks
Dave Rudolph – "Emerging Needs for Temporal and Spatial Data Precision" Dave Rudolph, with the University of Waterloo, started the symposium off with a very thought provoking presentation on the value of data. Dave used case studies to illustrate how different factors impact the quantity and quality of water resources, and how a small change can affect these conditions quickly and ...

Ultra-fine coatings on sediment grains influence nitrate and sulfate storage in soil
Tiny sediment grains are covered with a very fine-grained, complex mixture of minerals in an open fabric that results in a large surface area in contact with water between the grains. Scientists at the U.S. Geological Survey (USGS) are studying this microscopic layer and finding that the mineral composition of these coatings on sediment grains in the unsaturated zone (i.e., between land surface ...

Studies reveal why drinking water wells are vulnerable to contamination
New USGS groundwater studies explain what, when, and how contaminants may reach public-supply wells. All wells are not equally vulnerable to contamination because of differences in three factors: the general chemistry of the aquifer, groundwater age, and direct paths within aquifer systems that allow water and contaminants to reach a well. More than 100 million people in the United States ...
