YONKERS, NEW YORK USA – A landslide occurred when a portion of a stone retaining wall 
collapsed in Old Croton Aqueduct State Historic Park, sending mud and debris up against a senior housing complex. The 150 year old wall appears to have given way due to saturated ground conditions caused by a leaking water pipe, recent heavy rains, and melting snowpack resulting from higher temperatures. The collapse sent a wall of debris 24 feet (7 m) wide down an embankment and deposited 4 to 6 feet (1.2 – 1.8 m) of mud up against the housing complex. The mud and debris blocked access doors to the building and caused possible structural damage resulting in the dislocation of approximately 110 residents. Luckily, no injuries were reported.
After clean-up was complete, the old retaining wall needed to be addressed to prevent future issues. The State of New York, responsible for the property, contracted with industry leader Moretrench to drill 97 holes for a new retaining wall. Moretrench is a nationally renowned geotechnical contractor specializing in design/build solutions to meet the diverse conditions and construction challenges that impact so many of today’s projects.
With other portions of the 150 year old wall at significant risk of collapsing, the Moretrench team got to work. The new retaining wall project called for the installation of 24” OD x 23” ID casing adjacent to the previous wall. Once drilled, H-Beams were to be grouted into place to provide the necessary support for the new retaining wall.
The Yonkers site presented many challenges with significant sloping and unstable terrain. The environment required Moretrench to build an earthen bench to provide a safe, flat drilling pad for the work required. A Bauer Track Rig RTG RG 19T was used to complete the bench and drilling was completed with the same rig with two Doosan HP 1600CFM/200PSI (1510 l/sec, 13.8 bar) compressors added.
The ground formations at the site were varied, consisting of gravel, boulders, backfill, and rock pads. To conquer this, Moretrench teamed with DTH technology leader, Numa, and distributor Star Iron Works to drill with Numa’s Patriot 180 hammer and T580ND Super Jaws Overburden Bits. “On previous projects, we found Numa’s Super Jaws to be the best method for drilling in loose, unconsolidated ground conditions,” commented Moretrench’s Mike Fattorusso, Project Manager. “And Super Jaws did not disappoint at the site in Yonkers, providing great performance in a difficult environment.” In addition to great products, Numa also provided on-site support with Construction Product Manager Kris St. Onge who provided insightful, technical expertise. 
A total of 59 holes were drilled to a depth of 20 feet (6 m) and another 38 holes were drilled to 30 feet (9 m). Instead of using a multi-step process of drilling, tripping out of the hole, and then casing, the Super Jaws bits allowed for simultaneously drilling and casing in one step. Super Jaws makes this possible due to its unique wing design that retracts back into the guide body for extraction of all tooling while leaving the casing in place. A further challenge with drilling was with the confined site at the base of the previous wall that required a ½” (12.7 mm) tolerance and little room for error. But this was no challenge for Numa’s products with Fattorusso commenting, “The Patriot Hammer and Super Jaws bit drilled flawlessly straight holes allowing us to avoid delays caused by making corrections along the way. We simply were able to drill faster with Numa.”

New targets to reduce toxic and nuisance algae blooms affecting Lake Erie
WASHINGTON.- U.S. Environmental Protection Agency Administrator Gina McCarthy and Canada’s Environment and Climate Change Minister Catherine McKenna today announced that Canada and the U.S. have adopted targets to reduce phosphorus entering affected areas of Lake Erie by 40 percent. The targets announced today will minimize the extent of low oxygen “dead zones” in the central basin of Lake Erie; maintain algae growth at a level consistent with healthy aquatic ecosystems; and maintain algae biomass at levels that do not produce toxins that pose a threat to human or ecosystem health.
Through the Great Lakes Water Quality Agreement, Canada and the United States committed in 2012 to combat the growing threat of toxic and nuisance algae development in Lake Erie, and agreed to develop updated binational phosphorus reduction targets for Lake Erie by February 2016. The 40 percent reduction targets are based on 2008 loading levels. Canada and the United States have committed to develop domestic action plans, by no later than February 2018, to help meet the new targets.
“To protect public health, we must restore the Great Lakes for all those who depend on them,” said Gina McCarthy, Administrator, United States Environmental Protection Agency. “The first step in our urgent work together to protect Lake Erie from toxic algae, harmful algal blooms, and other effects of nutrient runoff, is to establish these important phosphorus limits. But, establishing these targets is not the end of our work together. We are already taking action to meet them.”
The Honourable Catherine McKenna, Minister of Environment and Climate Change said, “Canada recognizes the urgency and magnitude of the threat to Lake Erie water quality and ecosystem health posed by toxic and nuisance algal blooms. By establishing these targets, we strengthen our resolve to work with our American neighbours, and Canadian and U.S. stakeholders who share these waters, to protect the tremendous natural resource that is Lake Erie.”
Algae occur naturally in freshwater systems. They are essential to the aquatic food web and healthy ecosystems. However, too much algae, linked to high amounts of phosphorus, can lead to conditions that can harm human health and the environment. Since the 1990s, Lake Erie has seen an increase in algal growth that has compromised water quality and threatens the Lake Erie region’s recreation-intensive economy. The targets were developed after extensive public input from a diversity of sectors.
Quick Facts
• The 2015 harmful algal bloom in Lake Erie was recorded as the largest bloom this century.
• Modeling experts from the United States and Canada used nine different computer simulation models to correlate changes in phosphorus levels with levels of algal growth in order to determine phosphorus load reduction targets.
• A binational public consultation process was held between June 30 and August 31, 2015. Final targets were established following widespread support for the draft targets and the target setting process.
• More than 40 Canadian and American experts formed a binational team under the leadership of Environment and Climate Change Canada and the United States Environmental Protection Agency to develop the targets.
• In Canada, more than 50 individuals, groups and agencies representing Agricultural and other non-government organizations, Conservation Authorities, municipal governments, Ontario government agencies, First Nations, and Universities commented on the draft targets through an on-line tool and face-to-face discussions.

There was another story in the news recently highlighting the danger of unsafe excavation 
and the much needed changes with how to locate and dig around gas and utility lines. In Fresno County, CA, county workers were using a front end loader when a gas line was struck by the equipment, killing one man and injuring a dozen workers. It’s no question that if the line was properly located and a vacuum excavator was used to dig around the line then a life could have been spared. States and cities should require a vacuum excavator on all underground projects.
Vacuum excavation is defined as the process of using air or high pressure water to break apart soil and then debris is sucked up into the tanks. This method of excavation is commonly referred to as soft excavation technology and accepted as being much safer than traditional digging around underground facilities.
Vac-Tron Equipment has been the industry leader for vacuum excavation for over 20 years, innovating new ways of safer digging for companies globally. It is much less invasive in nature when compared to other traditional methods of excavating, has higher precision, and is leading to decreases in the amount of disposal of materials and accordingly much less surface restoration.
Vac-Tron’s equipment is made in the USA and distributed by over 40 nationwide dealers and 110 dealer outlets with new dealers being added internationally.
Vac-Tron recently announced 12 new innovations for vacuum excavation at the ICUEE show this year in Louisville, KY that will continue to keep the industry pushing ahead for safer digging. Here are a few highlights of new vacuum excavation innovations that were announced.
Vac-Tron HTV 573 PTO Truck: A NEW series of PTO truck driven systems available on Ford or Freightliner chassis. The full line of the HTV (Hydro Truck Vac) series has debris tanks ranging from 300 gallon to 1500 gallon in size. The Power Take Off of the truck drives positive displacement vacuum blowers that produce 1,000 to 3,000 CFM. These units are standard with a high pressure water system, full hydraulic rear door, reverse pressure, and the patented “Big Red” filter housing that cleans the air down to 0.5 microns (best in the industry) before it passes back through the vacuum pump. Air compressors and Hydraulic booms are also available on most of the HTV series units. Patent Pending.
Vac-Tron MT Series (Mud Trucks): New Series with 6 debris tanks sizes of 1500, 2000, 2500, 3000, 3500 and 4000 gallons. Over 45 degree hydraulic tilt, full open hydraulic locking door, PTO powered rotary vane vacuum pump, 25 inches of mercury, and reverse pressure, your chassis or ours. Great for cleaning up drill mud slurry.
A Wobble Head PROTOTYPE which is an innovative digging tool. Use a 6” hose head to dig a 24” hold by swiveling the end of the hose. Patent Pending.
