6 Purpose The City of Lansing, Michigan has been a leader in lead service line replacement and is nearing the end of its program. As the closest major utility to the Flint crisis, we have also been recognized for our work in assisting the City of Flint with getting their program off the ground. 11 Agenda History of the BWL Lead Replacement Program Challenges we have faced Keys to Success 12 Please consider the environment before printing. 6

7 Learning Objective Our goal for this presentation is that we can share from our experiences, whether they are good or bad, on some of the issues that you should consider as part of developing your own lead replacement program. 13 How We Are Different and Yet the Same We own the entire service line We have an accurate inventory (maybe) We have been actively replacing lead lines since the early 1990 s To date we have replaced nearly 17,000 services mostly with our pulling technique, and have less than 100 remaining active lead services in our system. 14 Please consider the environment before printing. 7

Please include your name and specify to whom you are addressing the question. 31 Halifax Water s Evolving Lead Program Reid Campbell Director of Water Services Halifax Water 32 Please consider the environment before printing. 16

17 Rationale Halifax Water has made continual adjustments to its lead program over the last 5 years as we have learned more about the occurrence of lead in our system. As we have adjusted we have encountered new challenges. 33 Learning Objectives Show how we have used research to continually modify our program. Share experiences in how we have built a multipronged program. Discuss challenges in striving to get all the lead out of our system. 34 Please consider the environment before printing. 17

18 Agenda Background on Halifax Water and Lead. Research and Program Adjustments. Overview of our Current Program Program Adjustments and Moving Forward. 35 Halifax, Nova Scotia, Canada 36 Please consider the environment before printing. 18

19 Sources of Lead in Halifax Drinking Water Water in water mains in Halifax is virtually lead-free Lead Service Lines (Stopped use in 1950 s) Lead Solder (banned in 1986) Leaded Brass Fixtures, pre-1997 can contain up to 8% lead 37 Halifax Water and Lead Replacing Lead Service Lines (LSL s) since the 1970 s. 2,500 public LSL s remaining today. Formal corrosion control program in place since Halifax Water has always achieved regulatory compliance for lead. Yet, we still see high lead numbers in our system. 38 Please consider the environment before printing. 19

20 Issues with the Historic Approach to Lead Most public LSL s have been replaced through proactive programs. 10% private uptake at the time of the public replacement. Outreach varied over time. Many barriers to home owners. No reliable estimate of how many private LSL s remain. Stopped doing partial replacements in Our ability to do public renewals is now linked to the customers willingness to deal with the private side. 100 year program at current rate of replacement. 39 Partial Replacements and Lead Release Lead Service Line Replacement (LSLR) sampling program with Dalhousie University. Pre-replacement sample. 72 hrs, 1 month, 3 months and 6 months post replacement. After 6 months: All full LSLR were below pre-replacement values. Many partial LSLR were above pre-replacement values. As a result of this research, in 2012, Halifax Water stopped conducting partial replacements where possible. 40 Please consider the environment before printing. 20

21 Number of Renewals Partial Replacements and Lead Release Impact of Discontinuing Partial Replacements Total # of Renewals Initiated by Public Renewal Initiated by Private Renewal # With Lead Remaining on Private 2016: 40 public LSLs replaced as of September 27 th 42 Please consider the environment before printing. 21

22 Lead (ug/l) Particulate Iron, Phosphate and Lead Release Pilot scale research showed: Correlation between cast iron mains and lead release. Doubling of orthophosphate dose leads to decrease in lead release. Impact on operations: Target unlined cast iron areas of distribution system for LSLR. Implemented doubling of orthophosphate dose in April Understanding Lead Exposure Compliance sampling in Canada and USA is based on a 1-L first draw sample post 6 hr stagnation. Research project 4 x 1L profile sampling shows that first litre does not often reveal peak lead. Result: Halifax Water uses 4 x 1L and a flushed sample, post 6 hr stagnation to assess lead exposure Only 28% of samples had peak lead in 1 st litre First Litre Max Lead 44 Please consider the environment before printing. 22

23 Current Halifax Water Lead Programs 1. Corrosion control treatment. 2. Corrosion control monitoring. 3. Customer sampling. 4. Lead Service Line Replacement Program. 5. Exposure reduction initiatives post disruption/construction. 6. Public outreach and education initiatives History of Corrosion Control Treatment 50:50 blend zinc ortho-polyphosphate to combat red water Switched to zinc orthophosphate at 0.5 mg/l PO 4 - Based on consultant recommendations as polyphosphates can increase soluble and particulate lead Pre ph Adjustment with Lime 75:25 blend zinc orthopolyphosphate dosed at 0.5 mg/l as PO 4 April 2016: Increased zinc orthophosphate to 1 mg/l as PO 4 - Implemented 1-year bi-monthly monitoring program in 40 homes with LSLs to monitor impact 46 Please consider the environment before printing. 23

24 2. Corrosion Control Monitoring a. Biweekly distribution system sampling at 21 sites for: ph, PO 4, Zn, Fe, Mn, Al, alkalinity, Cl -, SO 4, and turbidity. b. Quarterly monitoring of metal coupons. lead, copper and steel, 10 locations in distribution system. c. Bench and pilot scale research. Dalhousie University. Analysis of pipe scales and recommendations on corrosion control treatment. d. Lead Pipe Racks in distribution system. 47 3a. Customer Corrosion Sampling - Residential Monitoring Program Followed Health Canada Guidance document since Used Tier 1,1L post stagnation sampling until Tier 2 sampling since Target 100 homes, 50 with lead service, August. 4 x 1-L after six hrs stagnation plus 1L flush sample. Results of first L post stagnation have always had a 90 th percentile <15 µg/l. 48 Please consider the environment before printing. 24

25 3a. Customer Results Reporting and Recommendations Results letters sent to customers. Report total Pb and Cu for each litre sampled. Corrective actions advised if lead >10µg/L: Draw cold tap water for cooking and drinking. Flush > 6 hrs stagnation. Periodically remove and clean all faucet aerators. If pregnant, breastfeeding or have children under the age of six, consider using a household water filter (NSF certified). Boiling water will NOT remove lead! Recommend LSL replacement 49 3b. Customer Initiated sampling Complimentary 4L post stagnation profile sampling upon request in LSL areas. Same protocol as for annual residential monitoring. 4 x 1L profile after 6 hrs stagnation and 1L flush sample. Provided letters with results similar to annual residential monitoring. Have had significant increase in customer requested lead samples in 2016, from average of 15 to over 30 this year. 50 Please consider the environment before printing. 25

26 3c. LSL replacement program sampling Offered to any customer undergoing a full or partial replacement. Initially offered as part of research program. Over 200 customers since Sample analysis by Dalhousie University. Sample: Prior to replacement, 72 hrs after, 1 month, 3 months and 6 months. Same reporting protocol as for annual residential monitoring Lead Service Line (LSL) Replacement Program Current policy of lead service replacement: Following a private replacement. Upon disturbance of water man or LSL. Closing the gap on public and private renewal timelines, new program 2016: Standing offer with 3 contractors. Complete public and private LSLR in one day. Customer is still responsible for private LSLR. Customer has choice of Halifax Water contractor or one of there own choosing. 52 Please consider the environment before printing. 26

27 5. Exposure Reduction Initiatives Post Disturbance/Construction Flushing instructions provided to customers. New 2016: Pitcher type filters provided. Tested several brands at Dalhousie University. Supply one filter pitcher and 6 replacement cartridges (1 year supply) Public Outreach Pre- and post construction LSL Replacement Information to residents. Sample program reporting and recruiting. Nova Scotia Association of Realtors. Outreach to residents during water main renewal projects. Publications: Watertalk, Stewardship Report. Website. Developing a map for areas with potential LSLs based on house age and area served at time of construction. 54 Please consider the environment before printing. 27

28 Summary: 2016 Program Developments Response to Flint: Doubled rate of replacements. Doubled customer requests for sampling. Doubled phosphate dosage: Initiated bimonthly monitoring of 40 lead service customers to monitor change in corrosion control. Installing dedicated lead pipe racks in distribution system for sampling. Pre-Approved contractors to close public-private LSLR gap. Providing point-of-use filters. Developed a map of home construction pre Halifax Water Moving Forward: Developing Strategies for LSL Replacement Based on National Drinking Water Advisory Council Recommendations to the EPA. Replace all LSL s within a reasonable time frame. Remove barriers for private side replacement. Communicate with Customers. Shared responsibility. Develop an Accurate Inventory. Continued Corrosion Control. Continued Sampling. 56 Please consider the environment before printing. 28
