  5. Background • Previous collaboration with Lake County • Community Assessment for Public Health Emergency Response (CASPER) • National Center for Environmental Health • “Quick” and reliable • Household-based • Disaster or non-disaster settings 5

  6. Aims • Assess the degree of emergency or disaster preparedness of the community. • Assess community perceptions and experiences associated with geothermal venting. • Determine outdoor air levels of hydrogen sulfide and methane to identity new vents and potential areas of vapor intrusion in the community. • Assess private well vulnerabilities, including well characteristics and well water testing practices. 6

  7. (Inside Scoop) Aims • Assess ability to survive five months of weekly 2 hour conference calls. • Navigate winding, rural roads in pouring rain. • Perform door-to-door surveys in marijuana-growing region without getting attacked by dogs or their owners. • Execute uniform interview with diverse individuals in difficult situations (without entering their homes) after 3 hours of training. 7

  8. Methods • Community Assessment • Two-staged probability sampling • 30 Census Blocks x 7 households • 14 interview teams • November 26th – 28th • Weighted to account for sampling design 8

  9. Methods • Questionnaire • Geothermal gas venting • Emergency and disaster preparedness • Well water • 24 Questions? • 12 Versions? 101 28 9

  10. Methods 10

  11. Methods • Arrive • Count households • Divide number of households by 7 (n) • Pick a starting point • Approach every nth house • Track progress 11

  14. Results 14

  15. Results Household Demographics 15

  18. Results For how many days would you be able to stay in your home without anyone shopping for additional supplies? 18

  19. Results What is your household’s preferred method for receiving information during an emergency? 19

  20. No! I won’t Leave Without Toto!

  21. Discussion • Strengths • Tracking of interview teams • Greater understanding of emergency preparedness in Lake County • Successful collaboration • Trained DEODC for future CASPERs • First CASPER in California • First CASPER nationwide with air monitoring 21

  22. Discussion • Limitations • Vacant houses • Information Bias • Didn’t capture socioeconomic status • Spring Valley 22

  23. Survey Design Issues 23

  24. Survey Design Issues 24

  25. Additional Lessons Learned • Integrate epidemiology into disaster response • Track interview teams • Time and place • Offer participants an incentive 25

  26. Conclusions • CASPER was timely and relevant • Lake County households are affected by natural disasters • Households have taken steps to prepare for future disasters or emergencies • Recommendations to the County • Provide information on low-cost preparations • Use multiple communication media for messages • Prepare for pet-friendly shelters in the event of an evacuation 26
