II. Presentation by Dr. Rita Schoeny, U.S. EPA

Dr. Rita Schoeny, Senior Science Advisor for the U.S. Environmental Protection Agency’s Office of Water, gave a presentation to Subcommittee members entitled “What’s New in Microbes at EPA.” Dr. Schoeny’s presentation reviewed EPA’s Ground Water Rule and noted that fecal contamination will be defined in terms of indicators. She stated that the final rule (expected date of publication Dec. 2004) will look different than the proposed rule (May 2000). She also reviewed EPA’s revised total coliform rule stating that the proposed final rule is anticipated in 2006 and the Contaminant Candidate List 3 (CCL3) will be released in 2008. She discussed EPA’s development of guidelines for conducing microbial risk assessment and stated that EPA will be involving FDA in this process. She also reviewed the recently released National Research Council’s report “Indicators for Waterborne Pathogens”, which concluded no single, unique indicator (or small set of indicators) is capable of identifying all classes of waterborne pathogens. Chairman Condon thanked her for her time in meeting with Subcommittee members.


III. Approval of Minutes

It was MOVED and SECONDED to approve the minutes of the January 15, 2004, Virus/Microbial Subcommittee meeting.


IV. Review of Literature Search Results for Virus/Microbial Studies

Chairman Condon commented that the monthly literature searches that are being conducted to identify scientific papers on viruses/microbes in bottled and drinking water are turning up articles of importance to the industry. He also discussed that a response should be prepared to the paper by Larson et. al. that appeared in the May 2004 edition of Nursing Research (“ Predictors of Infectious Disease Symptoms in Inner City Households”). He will talk to Steve Edberg about preparing a response.


V. Update on EPA’s Candidate Contaminant List (CCL) and CCL2

Subcommittee members were provided with copies of a spreadsheet prepared by Chairman Condon that reviews and summarizes information on the CCL microbes, specifically whether they are waterborne, the illnesses they are associated with, their methods of detection, and their priority for research/regulation by EPA. The summary can be used for setting priorities for the Subcommittee’s focus. Sub-committee member were tasked to review the summary/spreadsheet and provide comments to Chairman Condon.

Members were also provided with copies of the April 2, 2004, Federal Register notice in which EPA published its draft Drinking Water Contaminant Candidate List 2 (CCL2). The CCL2 includes 9 microbiological contaminant candidates. Subcommittee members noted that Pseudomonas aeruginosa was not on the CCL2.


VI. Review of Virus Expert’s Deliverables

Subcommittee members discussed the two assignments completed in the spring by the Subcommittee’s virus expert Morteza Abbaszadegan. Dr. Abbaszadegan prepared a summary (dated March 26, 2004) entitled “Microbial Indicators of Pathogens Present in Surface and Ground Water”. Subcommittee members commented that no additional work was required by Dr. Abbaszadegan at this time on the assignment.

Dr. Abbaszadegan also prepared a review (dated March 16, 2004) of the paper “Norwalk-Like Virus Sequences in Mineral Waters: One-Year Monitoring of Three Brands” by Christian Beuret et al. (published April 2002 in Applied and Environmental Microbiology). Subcommittee members discussed whether there would be valuing at this date in asking Dr. Abbaszadegan to prepare a letter to the editor of AEM or possibly a full length paper that would review the conclusions of the Beuret paper. Kim Green was tasked to contact Annick Moreau, Danone, to ask her opinion. Kim will also share with Dr. Abbaszadegan a copy of the comments on the Beuret paper that have been prepared by Danone.


VII. Update on DWRF Project – Campylobacter

The Virus/Microbial Subcommittee had previously been asked by the Drinking Water Research Foundation (DWRF) to provide input on the ongoing project by Dr. Chris Madu that would respond to the October 2003 paper by Evans et. al. paper in Emerging Infectious Diseases (“ Hazards of Healthy Living: Bottled Water and Salad Vegetables as Risk Factors for Campylobacter Infection”). Subcommittee members shared with DWRF Chairman Jack West their thought that Dr. Madu should thoroughly address comments he received from CDC reviewers on his “Letter” to EID in his planned journal paper and that involving another expert such as Dr. Mike Miller from Albany Medical College in this effort would be appropriate.


VIII. Discussion of EPA Groundwater Rule

Subcommittee members continued discussions of EPA’s Proposed Ground Water Rule and possible implications to bottled water, specifically how FDA might apply the rule to bottled water. Chairman Condon reported that, as promised at the January 2004 Subcommittee meeting, he had prepared and distributed via e-mail to Subcommittee members a Summary of the Ground Water Rule. Kim Green reported that, as assigned at the January meeting, she contacted EPA to obtain updated information on the status of the final rule. EPA has a new manger for the rule, her name is Crystal Rogers. According to Ms. Rogers, EPA plans to publish its Final Ground Water Rule later this year (November or December 2004). This would result in a public water system implementation date of approximately December 2007 and, therefore, an FDA regulatory deadline of about June 2007. Ms. Rogers was unwilling to comment on what changes there will be between the Proposed Rule and the Final Rule. Kim also reported that, as assigned at the January meeting, she had investigated and obtained copies of comments IBWA previously submitted to EPA on the Ground Water Rule (February 1999 comments submitted on Preamble; August 2000 comments submitted on Proposed Rule).


IX. Discussion of Possible Need for Research on: Laboratory Testing for P. aeruginosa in Stool

As Dr. Steve Edberg was not present at the Subcommittee meeting, this item was not discussed.


X. Discussion of June 2004 IBWA/DWRF Meeting with CDC

Subcommittee members discussed continuing efforts to develop relationships with CDC’s person in charge of bottled water/drinking water. Kim Green reported that she, Joe Doss, IBWA, and Jack West, DWRF, met with CDC personnel on June 7, 2004. The purpose of the meeting was to meet and further develop relationships with CDC personnel who may be involved with drinking water issues, and to introduce CDC personnel to DWRF and the types of research that the Foundation performs. CDC representatives at the meeting included personnel from their Parasitic Diseases Division, Diarrheal Disease Epidemiology Section, Water Team, Laboratory Science Division, and Emergency and Environmental Health Services Division. Kim reported that Debra Levy of CDC’s National Center for Infectious Diseases (NCID), Parasitic Division has left. Debra was the person at CDC responsible for drinking water programs. CDC plans to hire someone in the summer of 2004 to replace her as their lead on drinking water. In the meantime, Dr. Michael Beach (CDC – Parasitic Diseases Section/Recreational Water) is filling in on these programs. Kim also reported that at the meeting, DWRF Chairman West provided an overview on the DWRF mission and recent research activities, and that CDC personnel discussed some of their current research involving drinking water, including a survey of tap water consumption and water treatment devices and biomonitoring for disinfection byproducts. At the meeting, CDC personnel also reiterated a continued interest in having bottled water labels provide consumers with information on which treatment methods are used in the product, viewing this as useful to immunocompromised individuals.

Chairman Condon stated that, although the Subcommittee’s goal is to develop relationships with CDC personnel, careful consideration must be given to what is discussed and shared with them.


XI. DWRF MAC Research Project with Europe

As requested by the Drinking Water Research Foundation Trustees, members of the Virus/Microbial Subcommittee continue to work with French investigators in developing a DWRF Project Proposal for consideration and funding that would examine Mycobacterium avium Complex (MAC) in drinking water. Steve Edberg will revise and rework a draft version of the proposal that will then be circulated to Subcommittee members for comment. Chairman Condon will also prepare and provide DWRF Trustees with information/introduction to MAC.


XII. New Business

The IBWA Virus/Microbial Subcommittee will next meet in Tampa, Florida, on Thursday, September 30, 2004 from 2:30 p.m. to 4:00 p.m.


XIII. Adjournment

There being no other business, a motion was made and seconded for adjournment. The motion passed, and the meeting was adjourned at 6:30 p.m.
