Spring and well water supply recovery after the Loma Prieta Earthquake 
South Skyline Association questionnaire April 2009

The following information that you are offering will be kept strictly confidential, as was done in the original study 20 years ago. The Loma Prieta Earthquake of October 17, 1989, drastically affected many spring and well flow rates in the South Skyline area. We will collate, correlate, and publish what we learn from this survey in a future ‘Skylines’. This information could prove useful for many of us after the next ‘Big One’ when our ground water will again surely be affected. If your home suffered a water loss after the Loma Prieta Earthquake please do this survey, at least PART I. 

Part I

1.    Name, Address, email

Name:        
Address1:   
Address2:    
Address3:  
zip:           
Email Address:     

2.    Do you get your water from a Well or Spring?    WellSpring

3.    How soon after the quake did your water supply greatly diminish?
    3a. (Well)      DaysWeeks
    3b. (Spring)   DaysWeeks
    3c. Uncertainty in above number    DaysWeeks

4. Was water trucked in, borrowed from a neighbor, rain water collected, and/or a new well drilled? Yes No
Any additional explanation:

5.    If the well or spring was not replaced, how long before the water supply returned to a barely usable amount, and then back to nearly a normal flow?
    5a. (Well)
        Barely usable: Months
        To normal/almost normal: Months
    5b. (Spring)
        Barely usable: Months
        To normal/almost normal: Months

Comments

Part II

This part of the survey is optional

6.Additional house and well location (useful if the geology Is important): (distances from intersections, county parcel no., and/or even GPS coordinates of well/spring location):

7. ORIGINAL WELL INFO:
    Elevation at spring or surface of the well
    Depth to well bottom
    pre quake, how many feet of water usually in the well in late
    summer
    or other time of the year
    (what time of the year Spring Summer Fall Winter)
    (driller’s record?/ other record?/ memory?)
    Depth to water in your well when supply first returned
    Current depth to water in your well
    Comments:

8.  IF a new well was drilled:
    How far from previous well
    Elevation at surface of new well
    Depth to bottom of new well
    Depth to water in new well after completion
    Current depth to water in your new well

9. Observations, comments, pre quake, post quake:
