Columbia CEC and RTC teams collaborate with NJ DEP on household survey of private well owners in NJ areas where well waters frequently exceed drinking water standards for arsenic

Columbia Superfund Research Program CEC and RTC collaborate with New Jersey Department of Environmental Protection (NJDEP) on Arsenic Survey

Through both Columbia SRP's monthly seminar/webinar series and ongoing meetings with our Research Translation Core (RTC) on arsenic in private well issues, the New Jersey Department of Environmental Protection (NJDEP) learned of the Columbia SRP Community Engagement Core (CEC) research on private well treatment and testing in Maine. This has resulted in a new collaboration with all 3 groups.  The survey has been sent to 2000 households in 17 New Jersy towns where private well ownership is high and arsenic occurrence in private well waters has been documented.  Interventions have already been undertaken in seven of the towns and the study will explore the effect of previous interventions as well as seeking to identify factors promoting or discouraging testing and treatment.  Following completion of the survey all 2000 households will be mailed information about resources for testing, treatment and basic information about arsenic in drinking water issues, including links to the arsenic awareness and testing videos produced by Columbia's RTC.

CU SRP research highlighted at Arsenic 2014 Congress in Buenos Aires

Several Columbia SRP scientists participated in the 5th International Congress on Arsenic in the Environment (As2014), held in Buenos Aires, Argentina between 11-16 May 2014. Ms. Sara Flanagan,  CEC and RTC scientist, received first prize under Theme 5: Mitigation Management and Policy  for the poster she co-authored with Dr. Yan Zheng, on “Arsenic exposure through well water and household behavior in a rural Maine community: Implications for mitigation”. In addition, Dr. Yu Chen gave an oral  presentation on “Gene-Environment Interactions between Arsenic Exposure from Drinking Water and Genetic Susceptibility in Cardiovascular Disease Risk and Carotid Artery Intima-Media Thickness in Bangladesh”, based on research conducted as part of Columbia SRP’s Project 1 with additional collaborators from Columbia, New York University, University of Chicago, and U-Chicago Research Bangladesh, Ltd., Dhaka, Bangladesh. A co-investigator of that research, Dr. Faruque Parvez, along with Project 6 Co-Investigator Dr. Kazi Matin Ahmed, also attended the conference. The theme of As2014 was "One century of the discovery of arsenicosis in America (1913-2014)", to commemorate 100 years of the discovery of the effects of arsenic in human life in Latin America.

Please find links below to both the poster and oral presentation abstract.

CU SRP presents findings on As impact on school children to Maine CDC

CU SRP scientists meet with Maine CDC, May 1, 2014: Drs. Andrew Smith, Joe Graziano, & Gail Wasserman (seated, L to R) and Nancy LoIacono (standing R)

CU SRP scientists Gail Wasserman, Joseph Graziano, and Nancy LoIacono presented findings from their research on the impact of arsenic on children's IQ to the Maine Center for Disease Control and Prevention (CDC) office in Augusta, Maine on May 1st.

The April issue of the Environmental Health journal published the study's paper, "A cross-sectional study of well water arsenic and child IQ in Maine schoolchildren.". The CU SRP study described in this paper included 272 childrent in grades 3-5 in 3 Maine public school districts. It examined associations between drinking water Arsenic and intelligence as measured by the WISC-IV test. The findings suggest that levels of Water Arsenic equal or greater than 5 mug/L, levels, which are below EPA national standards and occur frequently in some US regions, could pose a threat to child development.

The CU SRP scientists also translated their research findings for the representatives from three of the school districts whose students participated in the study.

Columbia SRP Director Joseph Graziano is the recipient of the 2014 Career Achievement Award from the Metal Specialty Section of the Society of Toxicology. He was honored by his colleagues with a special reception held at the SOT Annual Meeting in Phoenix on March 23rd.

The Career Achievement Award recognizes a senior investigator whose outstanding research accomplishments have substantially advanced the understanding of metals toxicology. This includes depth and breadth of scientific contributions, as well as the significance of those contributions in advancing the field. In addition, recipients have had a major influence in the education, training and mentorship of young scientists in the field of metals toxicology. They have also demonstrated leadership and service to the metals toxicology field. Finally, they have influenced regulatory and risk assessment decisions related to metals toxicology.

Dr. Graziano was selected for his pioneering work on lead an arsenic poisoning in humans, and as a leader in research and education.  He is known for his work on the development of Succimer, the drug that is now widely used to treat childhood lead poisoning, for his work on the effects of environmental lead exposure on child health and development, and for leading a major NIH-funded research program that examines the health effects of exposure to inorganic arsenic.  Dr. Graziano also recently chaired a National Research Council committee that ultimately gave guidance to the U.S. Environmental Protection Agency regarding their ongoing reassessment of the toxicity of arsenic.

Dr. Graziano's research career has been devoted to understanding the consequences of exposure to metals, both on the molecular and population levels. His work has taken him to Bangladesh, where his current research is aimed at understanding the consequences of arsenic exposure on the Bangladeshi population, and on devising strategies to reduce toxicity and provide arsenic-free drinking water, a problem that spans beyond the political borders of Bangladesh, to much of South Asia, from India to Vietnam and to some states in the U.S. Recent findings that both arsenic and manganese, both elevated in Bangladesh drinking water, are associated with cognitive deficits in children, add urgency to solving this enormous public health and environmental problem.

Chemistry World features van Geen on Well-testing for Arsenic

On March 27th, Chemistry World, an online magazine, published Nina Notman’s article on “Digging deep for safer water.” Notman consults with Alexander van Geen, Associate Director of the Columbia SRP, in her investigation of testing wells for high levels of naturally occurring arsenic in water used for drinking. Van Geen suggests, “A robust, affordable and permanent testing service will work well to remediate this issue in villages with a mix of high- and low-arsenic wells.” However, he and others warn that overtime there is a possibility that deeper aquifers could become polluted due to pumping. This could be the case where there are subsurface layers of clay that release organic matter, causing the reduction of iron oxides and, thus, triggering the release of arsenic. Please see the article for additional details of the impacts, sources, and solutions related to arsenic in drinking water.

Columbia SRP mourns loss of colleague Mark Becker

On Wednesday, February 26th, 2014, our colleague and good friend Mark Becker died in a multi-vehicle accident on his way to teaching class. Mark, associate director for Geospatial Applications at Columbia’s Earth Institute Center for International Earth Science Information Network (CIESIN), has made lasting contributions to the Columbia SRP. In the early years of our program, he taught a week long GIS Training Workshop introducing our scientists and students to the value of the spatial visualization of their data on arsenic contamination in Bangladesh. Mark then went to Dhaka and provided GIS training to build the capacity of Bangladeshi academics and policymakers to help them better understand and address their country’s overwhelming environmental health problems. As part of our Research Translation Core, Mark continued for several years to provide GIS expertise for our science projects both in the US and Bangladesh. He was generous and effective in sharing his knowledge with acclaimed scientists as well as local communities. In 2008, with the exponential growth of administrative, teaching, and other project demands, Mark passed the RTC baton. Tricia Chai-Onn and Kytt MacManus, two very capable geospatial specialists that he had trained and mentored, took his place on the RTC. Still Mark has always been just around the corner for consultation on SRP projects- always with a friendly smile and helpful suggestion. Mark used his great intelligence and extraordinary vision as both a teacher and a steward for the environment- together a powerful and enduring force. He will be greatly missed.

Columbia RTC presents NPL Superfund Footprint Mapper to EPA Sustainable and Healthy Communities (SHC) Research Program

SRP Research Translation Core scientists Meredith Golden and Tricia Chai-Onn presented a webinar on the Columbia University Superfund Research Program’s NPL Superfund Footprint Mapper on February 18th as part of the U.S. EPA Sustainable and Healthy Communities (SHC) Seminar Series.

The Superfund Footprint Mapper, funded by NIEHS, permits academic researchers, government regulators, and community stakeholders to visualize critical data about the area and inhabitants near Superfund sites to better assess the potential exposure of nearby vulnerable populations and therefore more effectively prioritize cleanups.  The ATSDR Geographic Research, Analysis and Services Program (GRASP) polygon shapefiles define the boundaries for most of the sites; the remaining sites are designated by EPA CERCLIS point data indicating the site centroid.

The Mapper includes over 32 socio-demographic variables from the US Census (year 2000), including race, education, linguistic isolation, and women of childbearing age. Using US Census Grids population data, these characteristics are aggregated to provide a more accurate profile of populations living within 1 and 4 mile “buffers” surrounding more than 1700 NPL sites across the US and Puerto Rico. School locations with student enrollment are mapped. Environmental data such as Brownfields, fault lines, and Toxic Release Inventory (TRI) data indicate additional potential health risks for residents.

As the Columbia SRP Research Translation Core considers updates and enhancements to the Mapper, the CU SRP RTC invites feedback from those who would like to use the Mapper to better understand, assess, and remediate environmental health issues near Superfund Sites. Please see below links to the NPL Superfund Footprint Mapper, NPL Superfund sites shapefile and point data, and a pdf of the webinar presentation.

RTC Scientist Stuart Braman Presents Student Videos at SRP Annual Meeting

Dr. Stuart Braman, Columbia SRP, presenting Barnard Student Videos on Arsenic in Drinking Water at SRP Annual Meeting, October 15, 2013, Baton Rouge

Columbia SRP scientist Dr. Stuart Braman presented both a poster and a talk on "Multimedia for Public Engagement" at the Superfund Research Program Annual Meeting in Baton Rouge. This was part of the day-long session for the SRP Research Translation and Community Engagement Core scientists and staff. The videos Dr. Braman presented were created by undergraduate students at Barnard College.

Columbia's SRP RTC has been working with state and local officials in northern New Jersey to provide awareness and educational materials to homeowners with private wells in areas where the chance is significant that naturally occurring arsenic will be present in drinking water at levels above state standards.  Barnard College undergraduates in two sustainable development workshops worked under RTC guidance to create three videos, a website and a brochure. The first video is addressed to children and its goal is to encourage children to talk to their parents about testing well water for arsenic, the second video addresses the same message to parents directly and goes on to briefly discuss treatment, and the third focuses on demystifying the water testing process.  The Columbia RTC will devote the next 9 months to working on distribution of the videos before beginning work on the 4th video.  New materials developed will take advantage of the research undertaken by the Columbia SRP CEC to identify specific barriers to water testing and treatment among private well owners in Maine. .
