Yamba is a small coastal community on the northern beaches of New South Wales (NSW), Australia. and is known as the "Jewel in the Crown" for Clarence Valley Council, a point which was reinforced when it won "The Best Town in Australia" in 2009. In early 2012, undermining in the southeast corner of Whiting Beach was exposing key infrastructure, including the footpath, road, stormwater pipe work and chamber, pressurized sewer and a car park. ELCOROCK® Geotextile Sand Containers were seen as an ideal solution to fit these criteria and were adopted after consultation with Geofabrics Australasia, Fisheries and Crown Land.

Chenango Contracting is progressing steadily on geomembrane installation to cover a part of the Allegany County Landfill in Pennsylvania, as the site has reached capacity. Phase II of the work is to be done later this fall. After that, there will be one more section to cover up. County legislators have said the entire landfill could be at capacity in about four years. The county has some decisions to make about what to do with garbage after that. Learn more here.;

Monument Valley Park in Colorado Springs, Colorado once had a beautiful pond. But with the city under budget constraints, management of the pond was suspended. The water slowly drained back into the groundwater, leaving behind an empty pond bed. The city's parks and trails manager is evaluating the possibility of installing an EPDM pond liner, or perhaps some clay, but nothing will be considered until the money is available. It's possible that some late summer rain will relieve the parks of irrigation costs, and if so the money might be available to fix the pond. Learn more here.;

The Montmorency Oscoda Alpena Solid Waste Management Authority Board in Michigan needs to cap a waste cell. Initial feelings were to use only clay as a temporary bandage; but the board is now leaning towards a linear low density polyethylene (LLDPE) cap in order to provide a longer-term solution and leachate control.

A 22 July 2010 slip opinion Appellate Division of the Supreme Court of New York finds that the New York State Department of Environmental Conservation did not make an error in approving the extension of operations at a CWM Chemical Services hazardous waste landfill (RMU-1) in Niagara County. Part of the dispute has surrounded the permitted use of a geosynthetic clay liner in site capping plans versus a much thicker compacted clay liner. (The GCL enabled waste capacity to be increased by 106,870 cubic yards.) In the opinion, Judge John Lahtinen writes, "DEC determined, and the record supports, that a GCL cover affords better protection, thus having a positive environmental impact. The agency also noted that allowing the GCL cover would decrease the truck traffic that otherwise would have been necessary to deliver clay for a GCL cover." Learn more here.;

The serious problems at the nuclear power plant in Japan have raised new doubts about the safety of nuclear energy. New exploration has yet to resume in the Gulf of Mexico after last year’s blowout of a BP oil well. And coal plants have been under a shadow because of their contribution to global warming. Meanwhile, natural gas has overcome two of its biggest hurdles -- volatile prices and questionable supplies. Learn more here.;

Dr Ian D. Peggs and I-CORP INTERNATIONAL have been contracted by Leighton Contractors in Australia to provide technical support and guidance for the installation of high-density polyethylene (HDPE) double lining systems in about 14 production water and related ponds at the Condabri and Reedy Creek coal seam gas plants presently being built in Queensland, Australia. The plants are owned by Australia Pacific LNG, a joint venture of Origin, Conoco-Phillips, and Sinopec. This I-CORP/Leighton Contractors cooperation arose from a previous project in which I-CORP provided expert witness support to Leighton Contractors for concrete protection liner failures in SX/EW mixers/settlers at the Gunpowder mine near Mt. Isa in Queensland.

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.;
