  1. Delaware Valley Early Warning System (EWS) September 24, 2008 Regional Response Team III Pittsburgh, PA

  2. What is the Delaware Valley EWS? An integrated monitoring, notification and communication network designed to identify and provide advance warning about source water contamination events Partnership of water suppliers, industrial intakes, emergency response agencies, government agencies and other relevant parties

  3. Early Warning Systems in the US and Abroad Only a relatively small number of EWS networks worldwide more prevalent in Europe and Asia heavily populated and industrialized waterways Historically developed in response to a major industrial contamination event and focus on organics detection Systems under development in the US are taking a more proactive approach

  4. Existing Early Warning Systems In Europe, Asia and Canada Rhine River River Trent Seine River Yodo River Han River St. Clair River In the United States Ohio River (ORSANCO) Lower Mississippi River Upper Mississippi River New York City Schuylkill and Delaware Rivers Susquehanna River Potomac River * AwwaRF #2527: “Design of Early Warning and Predictive Source-Water Monitoring Systems” (2002)

  5. History of the Delaware Valley EWS PWD Office of Watersheds begins Source Water Assessments 1998 - PWD first applied for funding – not educational enough 2002 – SWAPs complete – funding made available 2002-04 – Development and Optimization of EWS 2005 - Fully operational, optimization and upgrades continue 2006 – Annual user fee implemented to cover O&M 2007 – Deployment of new enhanced EWS website 2008 – Integration of CodeRED mass notification telephony system with DHS funding

  6. What makes the Delaware Valley EWS unique? Integration Data management Centralized access Automation Everyday utility Partnership approach to management decisions

  7. The EWS Coverage Area Schuylkill River Watershed Delaware Watershed with exception of: Tributaries DS Philadelphia NYC water supply 115 intakes

  8. Why is PWD leading the development of the Delaware Valley EWS? Operate the 3 most downstream WTPs in the Basin Provide drinking water to 1.5 million residents Experienced “close calls” (Athos I, Bridgeport industrial fire, transportation accidents) Recognize the benefit of better information about upstream water quality and events Understand need for a partnership approach

  9. Objectives of the Delaware Valley EWS Support existing notification protocols Develop a regional partnership Establish a secure forum for communication & information sharing Coordinate watershed-wide water quality monitoring Provide analytical tools for event response Provide information that will be valuable on a daily basis Build a framework that can be expanded in the future Protect water supply for over 3 million people

  10. Potential Sources of Contamination Wastewater Discharges Ag. Runoff On-Water Accidents Fires & Accidents Dam Sediments Sewer Overflows

  11. Components of the Delaware Valley EWS EWS Partnership Event Notification System Water Quality Monitoring Network Database and website

  12. Partnership Approach Partner buy-in & support essential for success EWS design based on input and needs of the stakeholder community Utility and Emergency Responder Surveys Stakeholder meetings Steering Committee meetings EWS Steering Committee

  13. EWS Partnership Initiatives Steering Committee Governing body of the EWS Voting seats for reps of participating utilities Advisory Committee - reps from govt. agencies (EPA, DEP, DRBC, USGS) Meetings open to all stakeholders Agreement of Participation Creates safe environment for information sharing Developed in response to concerns about confidentiality and liability for information provided to the EWS User fee structure Water suppliers Industrial intakes (Coming in 2009)

  14. Delaware Valley EWS Partnership 258 users in 47 organizations as of Sep. 2008 Water Suppliers PA Water Suppliers - 12 utilities, 23 WTPS NJ Water Suppliers - 5 utilities, 5 WTPs PA DEP / NJ DEP Delaware River Basin Commission US EPA USGS US Coast Guard County Offices of Emergency Management and Health Departments Industry – Exelon, Sunoco, PP&L, etc.

  15. EWS Industrial Users Company Facility BASF Corporation Belvidere, NJ Conectiv Energy (3) Edgemoor, Deepwater, Bethlehem DSM Nutritional Products Belvidere, NJ Exelon Corp (3) Eddystone, Limerick, Schuylkill Mafco Worldwide Corp Camden National Gypsum Co Delair, NJ Nu Star Energy (formerly Citgo) Paulsboro, NJ Philadelphia Gas Works (2) Richmond, Passyunk PP&L Martins Creek Rockwood Pigments Pipersville, PA Rohm & Haas Bristol, PA Smithfield Beef Souderton, PA Stepan Company Fieldsboro, NJ Sunoco (4) Eagle Point, Marcus Hook, Girard Point, Point Breeze Wheelabrator Gloucester Co Westville, NJ

  16. 115 intakes in coverage area

  17. 28 PWS participants

  18. 28 industrial participants

  19. Telephone Reporting Reporting party dials toll-free number Select phone notification for high level events or email only notification for low level events Touch-tone prompts record time and location The caller is encouraged to leave a voice message with event details The EWS automatically calls and/or emails all potentially impacted users Phone calls include general event alert followed by voice message with specific event information Emails contain time & location information and link to website Events can be updated from website

  20. Website Event Entry Form Risk: High sends telephone & email notifications, Low sends only emails

  21. Website Event Entry Form

  22. Water Quality Monitoring Network Collects water quality data from throughout the watershed 9 WTP intake or in-stream real-time stations - pH, DO, turbidity, temp, conductivity 83 USGS real-time flow and water quality stations EWS web-site provides centralized and secure location for real-time access to this data Proof of concept with simple water quality parameters at existing WTP intakes Pilot advanced monitoring technology in the future

  23. EWS Website and Database The EWS database receives and stores Telephony & website event information Water quality data EWS website provides Secure means of accessing and analyzing information Tools for determining appropriate event response Real-time water quality query Time of travel model Location for updating events List of contacts for follow-up Means of updating personal notification protocols Central repository for emergency response links RTDQ & HDQ for assistance in daily operations

  27. Water Quality Queries Real-time query 15 min data for past 30 days Historical data query Daily averages for past several years

  28. Water Quality Query Restrictions Currently – Real-time data query can be accessed by all users User Agreement protection Historical Data Query restricted to intake operators

  29. EWS Event History Events Reported Since January 2005 – full operation mode 115 water quality events 24 sewage discharges 22 oil spills 20 general notices (black fly spraying) 18 other (arsenic, leachate, etc.) 16 chemical spills 15 flood/reservoir release warnings

  30. Major EWS Events Athos-1 Oil Spill, 11/26/04 275,000 gallons of crude oil spilled into the tidal portion of the Delaware River at Paulsboro NJ PP&L Fly Ash Spill, 8/23/05 100 million gallons of water containing fly ash entered the Delaware River from PP&L lagoon Cyanide discharge, 6/14/06 Discharge through WWTP, 1000+ fish killed

  35. Next steps… PWD pilot biomonitoring technology Full incorporation of industrial intakes Industrial user fee Other telephony enhancements Trigger spill model from telephony Website enhancements Affected-intake based notifications Spill model expansion to tributaries Deploy Spill Model Analysis Tool Integrate system with PWD distribution system warning system (WSI) Oct 2: “Northeast Summit on Monitoring Technologies and Early Warning Systems for Drinking Water Supplies”

  36. Benefits of the EWS One call notifies all (does not fulfill NPDES notification responsibilities) One update informs all Increased notification speed Increased notification reach Ensures consistency in the event information Repeated notifications to each user Multiple notifications within each organization Event info provided in convenient format for notification recipients
