Director Joe Graziano testifies before Maine State Legislature

Columbia's SRP Director, Joe Graziano, testified before the Maine Legislature's Labor, Commerce, Research and Economic Development Committee on April 14th regarding the proposed bill LD 937, on Private Well Water testing requirements. Both Dr. Graziano and our SRP Community Engagement Core PI Yan Zheng also sent in written testimony for this bill and a similar one, LD 1162, presented to another committee.

Columbia’s CEC partner, Bob Marvinney had this to say:
“Joe Graziano brought a very important message to the Maine Legislature today with his testimony on LD 937, a bill which provides mechanisms to increase private well testing and remediation in Maine.  It was very helpful for the legislative committee to hear directly from a prominent member of the public health community on the issue of arsenic in private well water. We hope the Legislature will take some action!”

Referring to the research led by Dr. Graziano’s SRP Project 2 research, Michael Shepherd with the Portland Herald noted, “The issue gained more attention last year, when scientists from Columbia University and the University of New Hampshire released a five-year study of 272 students in grades 3 through 5 at schools in Manchester, Readfield, Monmouth, Wayne, Mount Vernon and Hallowell who were exposed to arsenic in water. It found that exposure to even low levels could lower IQ levels by as many as six points on a test.”

The majority of the committee voted to pass the bill as amended. A minority voted not to pass the bill. The full legislature passed with very strong bipartisan votes in both the House (108-40) and Senate (22-13) the Act to Ensure Safe Drinking Water for Maine Families (LD 1162), championed by Rep. Drew Gattine, Rep. Karen Vachon, and Rep. Gary Hilliard. However, on June 26th Maine Governor Paul LePage vetoed the bill.  An attempt to override the veto on June 30th fell four votes short in the House.  Proponents are hopeful that the growing support for well water testing will secure passage of future legislation.

Columbia SRP Student Caitlin Howe Writes for EpiBeat on Histone Cleavage Impacts

The editors of the new online epigenetics blog (EpiBeat) invited SRP student Caitlin Howe to write a short summary of her Letter to publish on the EpiBeat blog regarding her recent findings related to histone modifications. Ms. Howe and Project 3 PI Dr. Mary Gamble have identified a cleavage product of histone H3 in human peripheral blood mononuclear cells (PBMCs), which interferes with the measurement of downstream modifications, (such as H3K9me2). They reported this finding earlier this year in a Letter to the Editor, which was published in Clinical Epigenetics, the official journal of the Clinical Epigenetics Society.

Histone modifications are increasingly being used as biomarkers of cancer prognosis and survival. They are also novel targets of interest for environmental epidemiology studies.

CBS News Video Features Columbia SRP Director Dr. Graziano

As part of the online CBS News video "Health worries about Arsenic", Dr. Graziano explains that scientific research now attributes a wide range of long-term health effects from exposures to arsenic in food and water. Columbia's SRP studies indicate that prenatal exposure to Arsenic via drinking water can also alter DNA and cause serious health effects later in life. In addition to Dr. Graziano, the clip shows Columbia SRP graduate student Tiffany Sanchez conducting tests in the Center's Trace Metals laboratory.

February NIEHS SRP Research Brief focuses on CU SRP CEC collaboration: Assessing and Reducing Health Risks from Arsenic in Private Well Water

Columbia SRP Community Engagement Core PI Dr. Yan Zheng and Joseph Ayotte, P.G., a U.S. Geological Survey hydrologist collaborated together to co-edit a special section on arsenic for the journal Science of the Total Environment (STOTEN), Volume 505, 1 February 2015. Their summary paper, “At the crossroads: Hazard assessment and reduction of health risks from arsenic in private well waters of the northeastern United States and Atlantic Canada” is the first in a collection of thirteen papers

The SRP Research Brief summarizes the ongoing research on arsenic (AS) hydrogeochemistry, effectiveness of household well treatment systems, and the testing and treatment decisions of private well owners in several northeastern U.S. states and in Nova Scotia, Canada. It summarizes two research studies on household behaviors in response to elevated arsenic led by CU SRP Community Engagement and Research Translation Cores Co-investigator, Sara V. Flanagan. In light of all the research, Zheng and Ayotte conclude that to actually reduce exposure from arsenic in private drinking water wells, there must first be a better understanding of what actions people take and why. The authors suggest that homeowners in areas prone to high levels of arsenic in well water be provided with a larger range of options. An exposure-reduction tool box, for example, could consider the range of concerns and needs of homeowners and provide guidance to encourage well testing, treatment, and access to alternative water.

CU SRP Scientists Engage Visitors at Lamont Open House

CU SRP Community Engagement and Research Translation scientist Sara V. Flanagan discusses testing and treating well water at the Lamont Open House

Several Columbia Superfund Research Program scientists and students participated in the full day of activities at Columbia's Lamont Open House on Saturday, October 11th. Over 2700 visitors braved cold temperatures and torrential rains to learn about the latest findings and advances in environmental science, making the connection between rational evidence-based knowledge and the difficult choices regarding the planet's stewardship.

Dr. Yan Zheng and Dr. Qiang Yang (former SRP student) along with CU SRP CE researcher Sara Flanagan answered visitors' questions regarding, "What's in your Well Water?" In the United States, 43 million people drink from private wells; however, the government does not require routine testing of these wells. Many of the Open House visitors wanted to know where they could get their water accurately tested and evaluated. Even those who have already tested their water had questions on how often to test, how to interpret the results, why the standards vary from state to state, the most effective treatment options, and when to change the filters and what to do with the old filters. Laws and services vary in the tri-state area. The SRP scientists explained the science and directed well-owners to resources available for their residences. Meanwhile, to increase an understanding of the difficulty in obtaining clean water, SRP scientist Dr. Stuart Braman helped direct the "Race for Safe Water" activity. Even in the rain, kids learned how difficult is it to pump, carry, and deliver enough safe water for daily needs both in Bangladesh and Rockland County NY. Dr. Steve Chilrud also introduced visitors to the latest equipment for measuring personal exposures to air pollutions. In the quest to find the "dirtiest kid at the Open House", Chillrud used sensors to measure the "personal cloud of microscopic particulates" of enthusiastic volunteers.

To a packed auditorium of an older crowd, SRP scientist Dr. Beizhan Yan and collaborator Dr. Martin Stute, demonstrated and discussed the physical and environmental dynamics of gas production by hydraulic fracking. Stute pointed out that the gas industry has proceded quickly, without the benefits of scientific inputs. Now science has to catch-up. There must be a better understanding of the processes in order to ensure effective regulations to protect the environment and human health. Across campus, under the protection of a tent and raingear, CU SRP RTC scientist Meredith Golden helped students, parents, and retirees use the Columbia SRP's online interactive NPL Superfund Site Mapper and think about the location and potential exposures from hazardous waste sites in close proximity of schools, residences, and natural hazards such as storm surges and fault lines.

There were over 55 exhibits and 20 lectures reflecting Lamont's global multi-disciplinary coverage of the origin, evolution, and future of our planet. Visitors received flyers and fact sheets on the Columbia NIEHS Superfund Research Program.
