Bathurst Selected to Deliver Prestigious Giroud Lecture on Geosynthetics
The International Geosynthetics Society (www.geosyntheticssociety.org) has announced its selection of Prof. Richard J. Bathurst, P.Eng., Ph.D., FEIC, FCAE, to deliver the 2014 Giroud Lecture—one of the Society's highest distinctions. Since its first awarding in 1998, the Giroud Lecture has recognized exceptional achievement and influence in the field of geosynthetics and has been delivered every four years at the opening of the International Conferences on Geosynthetics, organized by the IGS. Dr. Bathurst is only the fifth to be bestowed this honor and will present the lecture at the opening of the 10th International Conference on Geosynthetics (10 ICG), Berlin, Germany, 21–25 September 2014.

Emory River to Reopen as Recreational Advisory is Lifted for TVA Kingston Site
The U.S. Environmental Protection Agency (EPA) and the Tennessee Valley Authority (TVA) plan to lift the recreational advisory for and reopen the Emory River on Saturday, 29 May 2010, at 7:00 a.m. The main river channel will be accessible to the public, but caution is advised. A no-wake zone has been established from Emory River mile 1.5 to mile 3 because large equipment remains in the area as TVA and EPA continue recovery of the Kingston ash spill.
Apex Receives Permit in Ohio
The Ohio Environmental Protection Agency has given the go-ahead for Apex to expand its landfill that has space in both Jefferson and Harrison Counties. The EPA issued Apex Environmental LLC a final solid waste permit-to-install and final air permit-to-install for the company's proposed landfill expansion. This includes vertical expansion. However, Apex Environmental LLC will retain the existing 4-to-1 grade on the northern slope of the landfill. This means that the buried waste under 12 acres of the northern slope will not receive any new waste and will not need to be uncovered, preventing some potential odors.

Pipeline construction in temperate rainforest
Pipelines International has published an article on its website regarding the construction of pipelines in rainforests. Among the many recommendations is the need for geotextiles or other geosynthetics to ensure access road stability. The soils at most of these sites do not have good load bearing capacity. Geosynthetics provide that support and allow dependable pipeline construction.

Leaking BC Landfill Leachate Debated
A new study linking chemicals in the Bonaparte River in British Columbia, Canada to leachate in the Cache Creek landfill is being debated, but many officials remain unconvinced. Several independent engineering studies performed on the landfill over the years have failed to find problems with leachate escapement; but some strong similarities in the landfill's leachate and Bonaparte River contaminants have been found. One consultant--who has not actually studied the landfill--has speculated that wrinkles in the liner and methods used to wrap the leachate pumps have resulted in holes in the liner.

Cautionary Tale: Geoelectric Integrity Surveys on Double Liner Systems
Leak location technology has greatly improved construction quality assurance (CQA) measures and, thus, geosynthetic lining system performance. But while the benefits of geoelectric surveys cannot be disputed, one should understand that not all lining systems are immediately survey-able. Ian Peggs' short tech note on double liner systems illuminates this issue but establishing minimum boundaries and pointing out troubles (challenges to surveys) that may result from certain system arrangements.
Geotextile Tubes: Florida to New Zealand
Orewa Beach Reef project near Auckland is progressing. Funding is being obtained steadily for the off-shore, geotextile-based artificial reef that will be constructed to stem erosion of the beach. Project supporters cite the success of other installations in Australia and New Zealand and even the acceptance and successful use of geotextile tubes in Florida.

Floods in Turkey Caused by Poor Infrastructure, Development
Inadequate infrastructure and chaotic urban development are being blamed for floods that have devastated Istanbul, Turkey’s largest city. Thirty years ago, Turkey's population was approximately 45 million. Today, more than 70 million people call Turkey home, and more than 70% of the population lives in urban areas. This breakneck growth and movement into cities like Istanbul has resulted in an infrastructure ill-prepared to properly support the nation's needs. Even moderate rainfall is thought to challenge Istanbul's system.

Geotextile Tube for Norriego Point
In Norriego Point, Florida, a proposal is gaining momentum to build a partial seawall with a T-head groin while repairing the two existing T-groins. Crews would later extend the stem of the T-head groin to the tip of the point with a sand-filled geotextile tube before constructing another T-head/terminal groin. A sheet pile wall would be constructed to protect the point. Lastly, sand would be piled on the point by a dredge and sea oats would be planted.

EPA to Kill Coeur d'Alene Liner Plan?
The U.S. Environmental Protection Agency may kill a plan to install a plastic liner along 10 miles of the polluted south fork of the Coeur d'Alene River. The liner was intended to keep clean surface water from mixing with groundwater polluted from past mining activity. Last summer, the liner drew criticism during public hearings over an expanded Superfund cleanup in the upper Coeur d'Alene Basin. Local residents worried the south fork would lose its natural look.
