Mesothelioma Due to Neighborhood Asbestos Exposure: A Large-Scale, Ongoing Disaster Among Residents Living Near a Former Kubota Plant in Amagasaki, Japan
Asbestos Disaster, 2020Co-Authors: Norio Kurumatani, Shinji KumagaiAbstract:We describe a serious on-going outbreak of Asbestos disasters which were uncovered in Japan in 2005 (the Kubota Shock). According to our epidemiological study, around 100 residential mesothelioma cases have been attributed to a single Asbestos Cement Pipe plant. That plant, now closed, was located in Amagasaki City, Hyogo Prefecture, west of Osaka. It was run by the Kubota Corporation, currently a large machinery company world-wide. A significantly increased risk of developing mesothelioma occurred among residents in the area which extends 2 200 m south south-east and 900 m north north-west from the center of the plant. This is in accordance with the predominant wind direction in the area, which blows from the north north-west. New cases of mesothelioma have continued to arise among residents, with the total number of mesothelioma patients currently near 200. Asbestos has been widely used since the early twentieth century, and therefore many factories world-wide, some of which are now closed, have handled Asbestos and Asbestos-containing products and may have spread Asbestos into the surrounding communities. Mesothelioma develops more than 40 or 50 years after the first Asbestos exposure. Public health policy-makers, health professionals, and industry need to recognize the serious health risks associated with the wide areas of neighborhood Asbestos exposure in the present and in the future.

mapping the risk of mesothelioma due to neighborhood Asbestos exposure
American Journal of Respiratory and Critical Care Medicine, 2008Co-Authors: Norio Kurumatani, Shinji KumagaiAbstract:Rationale: Little is known about neighborhood exposure to Asbestos and mesothelioma risk among residents around an industrial source of Asbestos.Objectives: To investigate the magnitude of the risk among residents by Asbestos exposure levels and to determine the range of the area affected by Asbestos.Methods: We calculated standardized mortality ratios of mesothelioma from 1995 to 2006 among the estimated population at risk that lived around a former large Asbestos Cement Pipe plant in Amagasaki City, Japan, between 1957 and 1975, the time when the plant had used crocidolite and chrysotile. The distance between the plant and homes and relative Asbestos concentrations obtained by diffusion equations involving meteorological conditions were used to determine Asbestos exposure levels among residents.Measurements and Main Results: We identified 73 mesothelioma deaths of 35 men and 38 women who had no occupational exposure to Asbestos. Among persons who had lived within a 300-m radius of the plant, the standar...

tetrachloroethylene leached from lined Asbestos Cement Pipe into drinking water with discussion
2016Co-Authors: Charles D LarsonAbstract:Tetrachloroethylene has been detected in concentrations ranging from a few micrograms per litre to several milligrams per litre in dead ends of water distribution systems made of vinyl-toluene-lined Asbestos-Cement Pipe. About 1600 km (1000 mi) of this lined Pipe is being used, primarily in New England. Tetrachloroethylene concentrations can be lessened by flushing and installing continuous bleeders, two of the solutions being suggested to correct this organics problem, which resulted from steps to control corrosion of Asbestos-Cement Pipe.

Pipe Bursting Asbestos Cement Pipe: The Process Is Established but What's Next
Pipelines 2015, 2015Co-Authors: Edward Alan Ambler, L. Pultz, John C Matthews, Ryan StoweAbstract:The City of Casselberry completed its $10.3 million Asbestos Cement (AC) pre-chlorinated potable water main Pipe bursting project in April of 2014 which replaced approximately 35 miles of AC Pipe. City staff has worked closely with the contractor, engineers and regulators from local and federal government to fully understand the applicability of the National Emissions Standards for Hazardous Air Pollutants (NESHAP) to Pipe bursting of Asbestos Cement Pipe. The Environmental Protection Agency and industry representatives have recognized the need to understand the potential environmental impacts of AC Pipe rehabilitation and have tasked the Water Research Foundation and the Battelle Institute with studying the various methods of AC Pipe rehabilitation. The environmental impacts of Pipe bursting AC Pipe have been analyzed with the Casselberry Water Quality Improvement Project as its pilot project. Results of the WRF study indicate that bursting AC Pipe is more environmentally friendly than removing the existing AC Pipe while providing the option to rehabilitate the existing Pipeline in place. This paper will present the results of WRF Project #4465 while clearly describing how to burst AC Pipelines and meet all existing regulations. This paper describes the challenges and successes of implementing a Pipe bursting project, from field application of Pipe bursting technology to working directly with regulators and rightof-way controllers who may be skeptical about Pipe bursting AC Pipe. A potential path forward through submission of a potential Administrator Approved Alternate to EPA that accepts a streamlined AC Pipe bursting process is also presented.

critical data needs associated with Asbestos Cement Pipe renewal methods
Journal of Construction Engineering and Management-asce, 2015Co-Authors: John C Matthews, Ryan StoweAbstract:AbstractAsbestos Cement (AC) Pipe accounts for approximately 15% of the total length of water distribution system piping in North America. Pipe renewal activities are needed to maintain these Pipes as they deteriorate, but concerns over the environmental impact and regulations associated with these construction methods are largely misunderstood. Confusion around these issues led this study to determine (1) what the regulations allow, (2) which renewal methods are applicable, and (3) the critical data needs associated with these methods when used for AC Pipe renewal. This paper describes current AC Pipe renewal regulations and practices (e.g., Pipe bursting, cured-in-place Pipe lining, etc.) and the critical data needs relating to AC Pipe renewal (e.g., study of the Asbestos fibers released in air, water, and soil during construction). These findings are valuable for water utilities in need of solutions for renewing their aging AC Pipes and in understanding regulations. The recommendations highlight the ne...

casselberry Asbestos Cement Pipe bursting project moving forward by leaving it behind
Pipelines 2014: From Underground to the Forefront of Innovation and Sustainability, 2014Co-Authors: Edward Alan Ambler, Bill Thomas, John C MatthewsAbstract:The City of Casselberry is nearing the end of its water quality improvement projects, which have utilized prechlorinated potable water main Pipe bursting to replace approximately 35 mi (184,800 linear ft) of Asbestos Cement (AC) Pipe. This project is likely the largest of its kind in the United States. The project has received $10.3 million in funding from the American Recovery and Reinvestment Act and the Florida Department of Environmental Protection's (FDEP) State Revolving Fund Program. The City, engineer, and contractor have worked very closely with FDEP and the Environmental Protection Agency (EPA) to determine the applicability of the National Emissions Standards for Hazardous Air Pollutants (NESHAP) to the fractured pieces of AC Pipe remaining in the ground after the Pipe bursting process. Utilization of Pipe bursting over traditional open cut provides many environmental, social, and economical benefits to the City's customers and residents. This paper will describe the working process in place to burst AC Pipe while meeting all EPA regulations and will describe all the efforts to complete the project.
