The construction of a 'Park and Ride' facility at a site in Cork City, Ireland has been proposed. The former landfill ceased operations more than 30 years ago. The proposed park-and-ride facility would sit upon 18,914 sq. m of the site. Some ground remediation and dynamic compaction would be required, and a geosynthetic barrier system would be installed to control any gas and leachate. Learn more here.;

SKZ, with scientific committee support from Cemagref and the Geosynthetic Institute (GSI), will host the 3rd International Symposium on Geosynthetic Clay Liners (GBR-C 2k10) 15-16 September 2010 at the Fortress Marienberg in Würzburg, Germany. Technical sessions will address shear and mechanical behaviour of GCLs, chemical resistance of GCLs, testing of GCLs under unsaturated conditions, behaviour of GCLs in landfill covers (case studies), regulations, new concepts and developments in the use of GCLs, and GCLs for hydraulic and construction applications.

Mumbai-based, polymer processing firm, EMMBI Polyarns plans to raise Rs 45-crore through an initial share sale next month, the proceeds of which will be used to augment its production capacity, a top official said. The IPO will launch in January 2010. The company plans to use its AquaSave brand to launch a range of products such as flexible water tanks, rain water harvesting systems, canal liners, pond liners and geosynthetics. Learn more here.;

The 185-mile-long, historic Chesapeake and Ohio Canal--more familiarly known as the C&O Canal--was compeleted in 1850 and served as a major transport corridor for goods such as lumber and grain. Today, it is a national park surrounded by more than 12,000 acres of land. Not long ago, a towpath began to fail when drainage pipe broke. The saturated slope gave way and exposed a main water line for Arlington County, Virginia. Repair of the slope was key both for the preservation of this historic canal and for the safety of Arlington's water supply. Maccaferri's Green Terramesh® system was selected to provide slope stability and vegetation for the natural look park patrons and officials seek along the C&O. Construction was quick, economical and effective. Read Pino Cignarella's case study.

Advanced Drainage Systems, Inc. (ADS) has added an innovative new product to its Arc line of plastic leaching chambers to meet the needs of septic leach field installers. The new Arc 36LP is specially designed for challenging installations such as high groundwater conditions or other site restrictions. Installing systems requiring shallow burial depths has several advantages, including greater separation from the groundwater, enhanced aerobic bacterial action and improved percolation rates. The new Arc 36LP chamber leverages more than 40 years of experience designing state-of-the-art engineered structures.

A severe drought along the Yangtze River region in central China has rendered nearly 1,400 reservoirs in Hubei Province temporarily unusable, devastated farm fields and made drinking water scarce, according to a report on Monday by Xinhua, the state news agency. One-fourth of all small reservoirs had what officials called “dead water” remaining, which could be pumped for use only in an emergency. Learn more here.;

The 9th International Conference on Geosynthetics (9ICG) Brazil - 2010 will provide an opportunity to learn about and discuss highly technical and scientific geosynthetics issues and their solutions. A primary objective of the conference is to present the most recent developments, improvements and new technologies from the international geosynthetics community. The IGS Brasil (Brazilian Association of Geosynthetics) and ABMS (Brazilian Association of Soil Mechanics and Geotechnical Engineering) will organize the conference under the auspices of the International Geosynthetics Society (IGS) in association with the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) and with the support of the ABINT (Brazilian Association of Nonwoven and Technical Textiles).

Within the next 12 months, Turks and Caicos Island in the West Indies will replace its small, unlined dumps with a large, new, modern landfill with a geosynthetic lining system. The landfill will include a self-sealing geosynthetic clay liner (GCL) under a 60-mil layer of a polyethylene geomembrane. Refuse will be spread and compacted daily over a small 100-by-50-foot working face and covered with a layer of soil, completely closing off any open waste areas each day. Learn more here.;

ASTM Committee D18 on Soil and Rock has announced work item WK38062, Revision of D6459 - 11, Standard Test Method for Determination of Rolled Erosion Control Product (RECP) Performance in Protecting Hillslopes from Rainfall-Induced Erosion. The balloted issue regards revising issues associated with Note 7 in the standard. Note 7 reads: "Distribution of rain drop size and intensity over the plot may affect results and needs to be evaluated on a case-specific basis." Learn more here.;

Not much can be done to halt the volume of oil washing in on the Gulf of Mexico shores, but some counties are installing a double line of protection with floating booms further out and fabric fencing just off shore. Jackson County, Mississippi, for example, is installing 50,000 feet of fencing. Learn more here.;

Bloomberg News is reporting that Earthjustice and 11 environmental groups have notified the U.S. Environmental Protection Agency that they intend to sue the agency to force it to issue regulations for the disposal of coal ash. The agency has waffled for the past decade on whether to regulate coal ash disposal at all, though more recent policy discussions would suggest some sort of regulation is forthcoming. Even regulated as non-hazardous waste, it could compel the utilization of geosynthetic barrier systems on the federal level, such as are required for municipal solid waste landfills.

By most reports, 2012's construction activity has been furious. Many manufacturers have moved advanced expansion plans begun or announced in 2011, and those decisions seems to be paying off as the on-site services side of the industry (e.g., installation and CQA) also reports significant increases in business. A number of companies have even hired on multiple new full-time employees and expected a considerable growth in seasonal work positions. But as the mid-year work dies down (at least enough to breathe), events take over the calendar. Here are four events (3 in Europe, 1 in the US) Geosynthetica is looking forward to.

Cleaning up the ash dump at the old Medfield State Hospital near Needham, Massachusetts, were tabled following protests and a need for professional engineering reviews. ADS Environmental Engineering, LLC. ADS warned against the 12-inch soil cap plan, recommending instead that a geotextile fabric be placed in between the clean soil cap and contaminated soil, to provide a temporary and long-term erosion barrier, in the event that erosion of the cap isn’t immediately noticed, and to provide a visual signal that erosion of the cap is occurring.
