8 SEE FOR YOURSELF MODULE 1, PART 1 8

9 1. Drinking Water Delivery System Learning Objectives Increase environmental literacy regarding drinking water delivery system Identify components of system Describe hazard-exposure-risk framework Understand how to identify contaminants and their sources Know where to find out more information from credible sources 9

10 Flint Cares Website 10

11 Drinking Water Delivery System Complex and changing system Closed system Three Components: 1. Water 2. Pipes 3. People 11

12 Water Cycle 12

13 Watershed Map 13

14 Three Components 1. Water 2. Pipes/Infrastructure 3. People 14

15 People People interact with the water system as Users, consumers Build and maintain Test and monitor Pay for, plan for the future 15

16 Water System Construction Human activity disturbs Flint s system from construction and water main breaks 16

17 Water Raw water from source Treated water Biologic agents: Bacteria, viruses Disinfectants added at treatment plant Contaminants Arsenic, Lead, Copper ph (acid- neutral-base) 17

18 Dissolving in Water 18

19 Water H2O Humor The ice cube says to the glass of water 19

20 Pipes and Infrastructure 20

21 Define Terms Water source Water treatment plant Water mains, water main breaks Service lines (public and private components) Plumbing and fixtures in homes, businesses, schools Water pressure, Residence time of water in system Point of Use (POU) filters Fire hydrants Drains & sewers 21

34 HAZARD EXPOSURE - RISK 34

35 Learning Objectives Understand the basics of risk assessment Mastering risk concepts can increase your credibility and advocacy Critically assess mitigation options Know where to go to learn more 35

38 Hazard Exposure - Risk 38

39 Exposure? 39

40 Hazard Exposure - Risk 40

41 U-M Flint Map of Flint Lead Service Lines (Nov 2016) Hazards = 1) Lead in Pipes and 2) Construction, Repair that Disturbs Lead Particles and Scale 41

42 Hazard Sources of Lead Lead service line pipes Lead in solder (before 1987) at joints Lead in household plumbing fixtures 42

43 Lead particles in galvanized pipe Brass faucets and valves 43

44 Scale Scale deposit Cross section of lead service line pipe 44

45 Sources of lead contamination When the City of Flint switched its water source in April 2014, the water from the Flint River was organically different (and lower ph) than Lake Huron. v=5qztoenx4re The Flint River water was not treated properly and once it hit the pipes (or fixtures) the corrosive water removed a protective coating (scale) on the inside of the pipes causing lead and copper to leach into the water. Source: Flint Cares website 45

46 Water Acidic or corrosive water Not appropriately treated In contact with metals Can result in damage 46

47 Coating pipes to prevent exposure 47

54 WATER SAMPLING & TESTING 54

55 Learning Objectives Improve environmental literacy for Flint residents Mastering sampling concepts can increase your ability to interpret results and take action Critically assess water testing results Know credible sources to learn more 55

61 WATER TESTING & SAMPLING 61

62 How do you see the glass? 62

63 Water Testing Understanding what you are testing for because test methods have limitations My portion of pipes City-wide Lead v. other contaminants 63

64 Why sample? Understand possible exposures As snap shot in time and changes over time Quantify lead concentrations in service lines Quantify lead concentrations in overall system at moment in time Become eligible for mitigation programs 64

65 In Home 2-Bottle Water Testing Obtain test kit and review instructions Use faucet within 24 hours but don t use water for 6 hours (e.g. over night); remove filters Watch the training video Take first use sample, second sample Complete paperwork Return sample Receive test results and interpret Take action 65

66 Video Step-by-Step Video of Sampling procedure 66

67 Tips: Taking a sample Plan ahead Involve your family members or friends Keep a written record or take a photo of your bottles with number visible next to the sink area especially if you are taking more than one sample Turn sample in where you picked up the container as quickly as practical Other tips? What has made this successful? 67

68 Behind the scenes at the lab What happens at the lab? Video 68

69 Statistical terms Sample is a snapshot in time of a dynamic system Only a small piece of the whole system Lead samples taken at homes in the same neighborhood may be related because pipes may have been installed together and construction may affect a geographic area 69

70 Interpret Your name Results: Lead 20 parts per billion 70

71 Other Types of Water Sampling Sentinel or Tier 1 sites Compliance Sampling Lead and Copper Chlorine Residuals Research sampling 71

72 90 th Percentile If 100 places are sampled on a day Arrange values from lowest to highest 90 th Percentile is the 90 th value out of

73 90 th Percentile If you arrange 100 values lowest to highest, the 90 th value is the 90 th percentile (Red line) ppb 73

77 With a group, create a plan Create a plan to 1) Stay current on water data, 2) sample your water at home Or 3) take action to reduce sources of contamination Together Share goals and barriers Brainstorm how to overcome barriers Write down your plan 77
