2 Lead and Copper Sampling Giving Your System the Best Shot to Stay in Compliance

3 Lead and Copper Rule Applies to CWS, NTNC, and adjacent systems Tries to ensure water delivered to customers is noncorrosive Compliance is based on 90 th percentile result Action Level, not a Maximum Contaminant Level (MCL) Lead Action Level = mg/l Copper Action Level = 1.3 mg/l

4 Lead and Copper Sampling Pool LEAD AND COPPER SAMPLING POOL PWSID # SYSTEM NAME: DATE: System Type [community (CWS) or non-transient, non-community (NTNC)] : System Begin Date: Population: # of Samples Required for Standard Monitoring: Location Code Physical Address (CWS) or Physical Location (NTNC) Year Built Plumbing Materials in Structure Tier 1, 2, 3 or OTHER Justification for designation of Tier 1, Tier 2, Tier 3 or "OTHER" EXAMPLES for CWS: Maple Lane, Anytown NC 1987 copper pipe w/ lead solder Tier 1 lead solder confirmed by swab test Lakeside Blvd, Anytown NC 1985 copper pipe new Tier 1 built in 1985 with copper pipe EXAMPLES for NTNC: 001 Breakroom in Main Building 1984 copper pipe new Tier 1 pipes are joined with lead solder 005 Restroom in New Wing 1998 plastic pipe OTHER built after 1985 with plastic pipe Sample highest -ers first. Start with -er 1 sites, then move to lower -ers.

5 Lead and Copper Sampling Pool Location codes should not change and should always remain on the sampling pool (even if you no longer sample there) New location codes assigned for new sampling sites If sampling pool changes, send the State a copy Try to sample the same sites from one event to the next

6 Sample Time! Recommend providing written instructions to the individuals collecting the sample Samples should be first-draw with aerators left in place Water must remained motionless in pipes for at least 6 hours Collect samples from a cold water kitchen or bathroom sink tap Don t wait until the last minute, you may not get all your samples back in time

7 I ve Got My Results, Now What? Fill out and distribute Consumer Notice of Lead Tap Water Results documents Provide any Special Notice documents that are required Calculate the 90 th percentile for lead and copper Provide Public Education if lead action level is exceeded

8 Consumer Notice of Lead Tap Water Results document Must be filled out and provided to residents at that sample location (or posted at the sample location for NTNC systems) Must be completed for all lead samples that are collected, even if they are non-detect Must be provided/posted within 30 days of getting your results Send one of these documents to the Lead and Copper Rule Manager within 3 months of the end of the compliance period

9 IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER [Insert name of your water system] appreciates your participation in the lead tap monitoring program. This notice is to inform you of the lead tap monitoring results for the drinking water sample collected at the location identified below: Street Address City Applies to every lead sample! Sample Collected Lab Results Received Lead Test Results/ Units Action Level/ Units MCLG Date: Date: mg/l mg/l 0 mg/l The action level is the concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow. The MCLG (Maximum Contaminant Level Goal) is the level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety. What are the Health Effects of Lead? Lead can cause serious health problems if too much enters your body from drinking water or other sources. It can cause damage to the brain and kidneys, and can interfere with the production of red blood cells that carry oxygen to all parts of your body. The greatest risk of lead exposure is to infants, young children and pregnant women. Scientists have linked the effects of lead on the brain with lowered IQ in children. Adults with kidney problems and high blood pressure can be affected by low levels of lead more than healthy adults. Lead is stored in the bones and it can be released later in life. During pregnancy, the child receives lead from the mother s bones, which may affect brain development. Infants and children who drink water containing lead in excess of the action level could experience delays in their physical or mental development. Children could show slight deficits in attention span and learning abilities. Adults who drink this water over many years could develop kidney problems or high blood pressure. (40 CFR 141 Subpart Q, Appendix B) Steps you can take to reduce your exposure to lead in your drinking water: Run your water to flush out lead. If water hasn t been used for several hours, run water for 15 to 30 seconds or until it becomes cold or reaches a steady temperature before using if for drinking or cooking. Use cold water for cooking and preparing baby formula. Do not boil water to remove lead. Look for alternative sources or treatment of water. Test your water for lead. Get your child tested. Identify if your plumbing fixtures contain lead. Contact Information: Call us at [insert system s phone#] or (if applicable) visit our Web site at [insert Web site here]. For more information on reducing lead exposure around your home/building and the health effects of lead, visit the Environmental Protection Agency s (EPA) Web site at call the National Lead Information Center at LEAD; call the EPA s Safe Drinking Water Hotline at ; or contact your health care provider. If you have specific health concerns, you may want to consult your doctor. You may also contact your county health department using the following Web site: Lead Consumer Notice Certification The public water system named above hereby certifies that the Consumer Notice of Lead Tap Water Results has been provided to its consumers in accordance with all delivery, content, format and deadline requirements specified in 15A NCAC 18C.1507 [141.85(d)].

10 Special Notice documents Required for any individual lead or copper samples that exceed action levels Must be provided/posted within 48 hours of getting your results Send a copy of all Special Notice documents to the Public Notification Rule Manager within 10 days of completing the notice

11 IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER SAMPLE Only for North Carolina s Rules Governing Public Water Systems (15A NCAC 18C) require that a public water system sample for certain contaminants that may occur in the drinking water distribution system. For many contaminants, multiple water samples are necessary to determine a system s compliance with the water quality standards. Although several sample results may exceed the allowable limits, the system may be in compliance based on multiple sample results and will not be required to perform system-wide public notification or take corrective action. However, the consumers of the drinking water at an individual location where the allowable limits are exceeded are still susceptible to adverse health effects. The purpose of this notice is to inform you of the analytical results for the drinking water sample collected at the location identified below. Since the allowable limit was exceeded at this location, the potential health effects are also included so you can take any precautionary measures you feel are necessary to further protect your health. Street Address City individual samples over the ac-on levels Speci al Notice about your drinking water Sample Date Parameter Tested Results / Units Action Level / Units Lead mg/l mg/l Copper mg/l 1.3 mg/l Potential Health Effects: [Standard Health Effects Language for Public Notification from 40 CFR 141, Subpart Q, Appendix B.] LEAD - Infants and children who drink water containing lead in excess of the action level could experience delays in their physical or mental development. Children could show slight deficits in attention span and learning abilities. Adults who drink this water over many years could develop kidney problems or high blood pressure. COPPER - Copper is an essential nutrient, but some people who drink water containing copper in excess of the action level over a relatively short amount of time could experience gastrointestinal distress. Some people who drink water containing copper in excess of the action level over many years could suffer liver or kidney damage. People with Wilson's Disease should consult their personal doctor. If you have specific health concerns, you may want to consult your doctor. You may also contact your county health department using the following website: or the EPA s Safe Drinking Water Hotline at 1-(800) Exceedance Awareness Date: Date Notice was Distributed: Method of Distribution: For more information, please contact: Responsible Person System Name System Address (Street) Phone Number System PWSID# System Address (City, State, Zip) Special Notice Certification: The public water system named above hereby affirms that special public notification has been provided to its consumer in accordance with all delivery, content, format, and deadline requirements specified in 15A NCAC 18C.1523(c).

12 Calculate the 90 th percentile results Place all sample results in order, lowest to highest Multiply the number of samples by 0.9 The sample corresponding to this number is your 90 th percentile result Do this for lead and copper separately

13 90th percentile examples If you have ten samples, then 10 x 0.9 = 9 Your 9 th highest sample is your 90 th percen-le If you have twenty samples, then 20 x 0.9 = 18 Your 18 th highest sample is your 90 th percen-le If you took only 5 samples, just average your 4 th and 5 th highest sample to get your 90th percen-le

14 My 90 th percentiles are Above the Action Levels If lead 90 th percentiles are above the action level, then public education required. If lead and/or copper 90 th percentiles are above the action levels, call your local regional office or the Compliance Rule Manager to determine the course of action Requirements depend on system size.

15 Lead Education Only for 90 th percen-les of Lead that are above ac-on level. [Insert name of water system] found elevated levels of lead in drinking water in some homes/ buildings.
