  • H2S Oxidation System for Water Treatment Facilities

    A new water treatment facility in the town of Jupiter, Florida, was causing a serious odor problem. H2S removed from the purified water was being released into the atmosphere. Complaints about the odor came from the residences and businesses downwind of the treatment plant. A turnkey LO-CAT® Hydrogen Sulfide Oxidation System designed to process 30,000 CFM of air containing 250 ppm of H2S ...

  • Meeting Melbourne's future demand for water using aquifer storage and recovery

    Melbourne is one of the fastest growing cities in Australia. City West Water (CWW) has developed an Integrated Water Cycle Management (IWCM) Strategy which includes the development of aquifer storage and recovery (ASR) schemes to store recycled water and storm water to assist with meeting future growth, where these schemes can be demonstrated to be viable and cost effective. The investigation ...

  • GroundWater Markup Language (GWML) – enabling groundwater data interoperability in spatial data infrastructures

    Increasing stress on global groundwater resources is leading to new approaches to the management and delivery of groundwater data. These approaches include the deployment of a Spatial Data Infrastructure (SDI) to enable online data interoperability amongst numerous and heterogeneous data sources. Often an important component of an SDI is a global domain schema, which serves as a central structure ...

  • Investigating and mapping spatial patterns of arsenic contamination in groundwater using regression analysis and spline interpolation technique

    The present study investigates the hypothesis that arsenic concentrations correlate with tubewell depth, and examines the effectiveness of spline interpolation, specifically completely regularized spline (CRS) and spline with tension (SWT) in estimating the magnitude of arsenic contamination in groundwater in Thanh Tri, a densely populated district located in the southern part of Hanoi City, ...

  • Village Drill: The Portable Water Well Drill

    The National Academy of Engineering declared that having access to clean water is still one of the 14 grand challenges of the 21st century. In many regions of the world men and women spend hours every day seeking out and carrying back water to their homes. This water is often filled with bacteria that can lead to illness and even death. The World Health Organization reported ...

  • Village Drill Digs Deeper: A Look Below The Surface

    Access to water is a number one priority for every living creature — just ask these elephants! Not all water is safe for humans to drink though, and many people don’t live close enough to a source of clean and fresh water. The solution to this problem is the same one humans have been using for the past ten thousand years: digging a well. Luckily wells ...

  • Storing Heat Underground

    Underground thermal energy storage (UTES) is a system that uses inter-seasonal heat storage, storing excess heat from the summer for use in winter heating, and the cooling potential from winter for cooling in summer. A cost-effective, low-energy and low-risk proven renewable technology, UTES reduces carbon emissions by up to 60% and is becoming an increasingly popular choice for residential, ...

  • The use of shallow high resolution seismic reflection data to determine drilling locations at the Apache powder superfund site.

    INTRODUCTION Groundwater contamination at the Apache Powder Superfund Site in Cochise County, Arizona includes dissolved nitrate-N and perchlorate. Past studies have determined that these contaminants migrate laterally from a perched zone underlying Apache Nitrogen Products, Inc. operating areas into the shallow aquifer of the San Pedro River alluvium (shallow aquifer). The base of both the ...

  • Who Owns Groundwater?

    California’s drought underscores the need to improve how the state - and the rest of us - divvy up a resource in demand. Grapevines march across wires strung along rolling hills, their little trunks improbably supporting heavy black fruit. Cindy Steinbeck’s family has been farming this land since 1920. They grow Zinfandel, Viognier, Cabernet, Merlot, and Petite Syrah grapes but are ...
