America's Infrastructure
The sagging state of the American infrastructure is well known. The recent collapse of more than 20 levees during the flooding in the Midwest is more than telling. But the Economist has now weighed in with a rather stark, short essay on the funding and application needs. Transportation and water management are of major concern. Read more.

Demolition Geotextiles
While the primary uses of geotextiles include separation, cushioning, drainage control and filtration, another major use has grown in recent years: demolition control. The durability of geotextiles and finer apperatures have seen demolition crews go increasingly for them over more traditional site demolition wraps like chain link. The materials are used for blast, dust and debris containment.

Dewatering Tubes in Mining
Pacific Gold Corp. has annouced that it is progressing on new design approaches for desanding at the Black Rock Canyon gold mining operation in Nevada's Lander County. As part of their future approach, they anticipate using geotextile dewatering tubes to eliminate fine gravels from being delivered to the settling ponds after initial gold recovery. This will allow for mostly clean water to be reprocessed back into the screening operations.

Long-Term Mining Boom
World prices for precious and semi-precious metals have vaulted in the past few years, and this spike in demand has helped fuel tremendous growth in the mining industry. But while prices have somewhat stabilized, growth will continue. Australia forecasts a 70% rise in employment (90,000 new jobs) in mining through 2020 in the mining sector. And these projects will also require environmental controls, which is where geosynthetics enter in.

Liner Dispute
Mining company Glacier Northwest is at loggerheads with people in the Seattle area now that the firm wants to expand a sand and gravel mining operation on Maury Island. To do so, Glacier would need to encapsulate contaminated soil in geosynthetic linings. Opposition to the project claims that the company's design is of a landfill, not a "containment facility" as maintained. Landfills are banned on Maury Island.

Future Nickel Mining
Nickel comes in two types: laterites and sulphides. The latter is deeper in the earth but easier to process. The former is the dominant sort in today's mining, but not by choice. It seems to be the lionshare of accessible deposits right now. Laterite mining is near the surface, but the nickel requires acid leaching, high temperatures and more stringent environmental controls.

Post-Mining Creek Restoration
The Maryland Bureau of Mines is tackling a decades-old acid mine drainage problem. The $1.2 million project goal is to transform Bloomington's Aaron Run into a fresh water creek that can sustain fish. The first phase of the work's bid will be awarded soon with a second phase solicited and awarded closer in early 2009.

Engineering Demand in Mining
Canada's Globe and Mail newspaper reports that Canada's skyrocketing demand in energy and mining sectors is producing a hard-to-fill order for engineering and technical services. The Canadian mining industry is thought to need 92,000 more professionals by 2017, many of them engineers and engineering technologists. These projects require significant environmental controls, access roads and remediation readiness too.

Mining Cleanup Tax
In Florida, a higher tax will be placed on phosphate companies to encourage quicker closure of former gypsum operations. Florida has a long successful gypsum mining industry, but its environmental legacy is not nearly as admirable. Significant cleanup and capping are required for operations dating back decades. The Ledger article includes an interesting close-up photo of a geomembrane being seamed.

BC Chooses Bituminous Geomembrane
A former copper mining site that has polluted waters in British Columbia, Canada, will be capped with a bituminous geomembrane as part of the site's $4.5 million remediation project. The project will cleanup copper leachate from now through 2010 and clean soil on top of the cap will be planted with vegeation. The end result will be not just safe land and water but a situation for replenishing Vancouver Island's fish stocks.

Mining Remains Strong
Despite slowing demand in the US, the mining and metals sector is expected to remain strong for Eurpoean groups, reports Thomson Financal Network. Demand in China and India will help keep mining commodities prices--iincluding gold, copper and silver--high. Those prices also influence new developments, and they'll require significant environmental controls, such as leach pad liners.
