Containment

Prof. Robert M. Koerner has come out with the Sixth Edition of Designing With Geosynthetics. As with prior volumes, it comes with helpful test questions after each chapter with answers provided at the end of the book. Currently, Koerner is professor emeritus of Drexel University.

Several investigators have reported higher densities of indicator bacteria after dewatering of anaerobically digested biosolids, an inevitable byproduct of the wastewater treatment process. The effects of these processes on the sudden increase and regrowth of fecal coliform and E.coli are examined in the latest issue of Water Environment Research (WER), the popular journal published by the Water Environment Federation (WEF). Formerly available to subscribers only, selected WER articles are available free to the public on a monthly basis through an open-access program.

On the US Environmental Protection Agency's website, they have a concise page dedicated to general anaerobic digestor information. Learn about biogas recovery and power/funding potential in sections like "AD 101," read the FAQs, get contacts, and more. Learn more here.;

The Green Bay Press Gazette reports on the growing acceptance of anaerobic digesters on farms. The average cost of $1.5 million has limited adoption, but as more farms adopt them and more systems are developed, costs are coming down and beneficial power generation revenue is realized. Geomembrane containment liners are gaining greater acceptance, though greater awareness of the potential is needed, the Press reports. Learn more here.;

The Arizona Department of Environmental Quality (ADEQ) is concerned over too little regulation and oversight in some mining operations in the state. One uranium mine that was inspected recently as cited for numerous problems, including a number of pour patches on a geomembrane and an unchecked pipe penetrating one of the pond liners.

With more than 600 coal ash ponds in the United States, and with new rules potentially coming into effect to require liners for these facilities, every state is having to re-evaluate its handling of coal ash waste. In South Carolina, the Washington Post reports that 20 power company sites face closure and a need to reline their waste cells, if and when the new rules are enacted. Learn more here.;

The newly created, 160-acre Royal Palm Beach Commons Park in Florida has been constructed on a former golf course. When the tee boxes and greens were excavated, arsenic-contaminated soil had to be stockpiled. Arsenic was part of the herbicides used on the course for many years. Now, the soil is contained on an 18-foot-high mound behind a residential home. A 20-mil liner has been installed for containment. Residents want the arsenic soil moved, but the city says it would be too expensive. Learn more here.;

Though the threat of a hurricane at our Florida office this week caused us to prepare for shutting down our servers, we (and our industry's companies) managed to accomplish quite a bit. Newsletters were launched, conferences were furthered, second quarter statements were issued, and so much more. Catch up on the week's action in our review column. 8/22/08

The organizers of EuroGeo 4--the 4th European Conference on Geosynthetics--would like to remind readers of the early registration deadline (31 July 2008) and of the three technical courses that will be held in conjunction with the event. The technical course subjects are geosynthetics in reinforcement, waste containment and hydraulic applications. Read more.
