  1. Virginia’s BEACH Monitoring Program Michele M. Monti Division of Zoonotic and Environmental Epidemiology Office of Epidemiology Virginia Department of Health

  2. Virginia’s BEACH Monitoring Program • BEACH Act of 2000 • Beaches Environmental Assessment and Coastal Health Act – 10/10/2000 • beaches in VA had been monitored since 1960’s Norfolk & VA Beach • EPA BEACH Act funds created a state-coordinated program in VDH starting in December 2001 • funds used for 2002 monitoring season @ VA Beach and Norfolk

  3. Virginia’s BEACH Monitoring Program • Sampling conducted by local health departments or health districts • Virginia Beach and Norfolk – long-term monitoring programs - 2002 funds • Hampton, Newport News/Yorktown, King George Co. began beach monitoring in 2003 • Eastern Shore and Gloucester in 2004 • Festival Beach in Mathews Co. in 2006

  4. Virginia’s BEACH Monitoring Program • What are the requirements? • States must adopt EPA Bacteria Criteria for Recreational Waters

  5. VA Water Quality Standards – Effective 1/15/03

  6. Indicator Organism for Virginia’s Marine waters • Enterococci • Enterococci instead of E. coli because enterococci has been found to be a better indicator of gastrointestinal illness in swimmers. • EPA single sample standard for enterococci: Cannot exceed 104 cfu • At 105 cfu or above, we issue a swimming advisory

  7. Waterborne Pathogens • Enteric organisms - found in fecal wastes • Giardia, Cryptosporidium, Campylobacter, Salmonella, E. coli, Hepatitis A, norovirus • Indigenous organisms - naturally occurring in marine/estuarine environments • Vibrio, Mycobacterium

  8. Sources of Contaminants • Stormwater drainpipes • Pets (esp. dogs) • Boat holding tanks • Wildlife (waterfowl, raccoons, deer, etc.) • Overflows at pumping stations, sewage treatment plants, residential & commercial sewage overflows (i.e., septic and sewer backups/failures/ overflows)

  9. Virginia’s BEACH Monitoring Program • What are the requirements? • States must adopt EPA Bacteria Criteria for Recreational Waters • States must submit beach water quality monitoring and notification data to EPA • XML schema - STORET • 1x/year submission • Web-enabled database for bacteria data - 2007

  10. Virginia’s BEACH Monitoring Program • What are the requirements? • States must adopt EPA Bacteria Criteria for Recreational Waters • States must submit beach water quality monitoring and notification data to EPA • Monitoring Plan – frequency, locations • QA/QC plan; tiered monitoring plan; protocols for sampling collection and analysis; predictive tools (for anticipating problems; pre-emptive closures)

  11. Virginia’s BEACH Monitoring Program • weekly monitoring – all beaches Tier 1 (48) • season mid-May thru September • Approved QAPP – includes protocols for sampling & analysis • working on rainfall & bacteria predictive model, not enough data, site-specific • pre-emptive closures/advisories based on rain and sewage overflow

  12. Virginia’s BEACH Monitoring Program • Sterile 100 ml bottles used for beach water sample • Meters used to obtain dissolved oxygen, salinity, temperature and pH of water • Samples must be delivered to lab & analysis begun w/in 6 hours

  13. Methods/Labs Used for Enterococci Analysis • Enterolert • VA Beach • Newport News Waterworks • Method 1600 - MF • Norfolk • VDH -Shellfish Labs • Accomac – eastern shore • State lab – DCLS

  14. Virginia’s BEACH Monitoring Program • What are the requirements? • States must adopt EPA Bacteria Criteria for Recreational Waters • States must submit beach water quality monitoring and notification data to EPA • Monitoring Plan – frequency, locations • Notification Plan – when and how to issue an advisory; public scrutiny of monitoring plan; press releases, web page(s)

  15. Virginia’s BEACH Monitoring Program • Reporting to the public • Reporting to local govts • VDH web page: • www.vdh.virginia.gov • http://www.vdh.virginia.gov/Epidemiology/DZEE/BeachMonitoring/

  16. Media Relations • Establish good relationships w/ your local reporters

  17. Public Notification and Risk Communication • Swimming Advisories • 2004 – 11 beaches, 27 advisories, 114 advisory days • 2005 – 8 beaches, 14 advisories, 43 advisory days • 2006 – 4 beaches, 8 advisories, 43 advisory days (*33)

  18. Problems: Solved • Hampton - diverted stormwater away from beach; repaired crack in ww pipe • Newport News – illegal hookup of ww to sw; ghost ww pipe found and capped; illegal hookup of trailer park ww to sw

  19. Microbial Source Tracking - VA Tech • Source tracking • Antibiotic resistance analysis • Dr. Charles Hagedorn • Fluorometer – human or animal?

  20. Indicator/Pathogens Rapid Methods Study - VIMS • PCR Analysis (standard and real-time) • Dr. Howard Kator, Dr. Kim Reece • E. coli, Enterococcus faecalis/faecium, • Staphylococcus sp. • noroviruses w/ comparison to standardized culture assays
