1. 1 Leah Walker California Department of Health Services Division of Drinking Water and Environmental Management October 2001 DHS TurboSWAP Welcome to TurboSWAP, the electronic method to Turbocharge your source water assessments!

2. 2 What is TurboSWAP? A database application to produce source water assessment reports A quick and easy method to produce complete, consistent, and understandable assessments. –Includes a user friendly interface that guides the user through the process. –Includes a function to submit completed assessments to a centralized database.

3. 3 TurboSWAP Features Built-in pick lists of water systems and drinking water sources customized to the user. This minimizes data entry errors. Status reports that allow the user to track progress. Function to update the list of systems and sources.

4. 4 TurboSWAP Development Developed by: University of California, Davis Information Center for the Environment Under the direction of: California Department of Health Services Division of Drinking Water and Environmental Management

5. 5 TurboSWAP Specifications The program was designed in Visual Fox Pro and stores the data in a relational database. The functions to submit data to DHS and update systems and sources from DHS use FTP to transfer data.

6. 6 TurboSWAP Users 21 DHS District Offices 34 Local Primacy Agency Counties Water Systems and other entities by request (currently 71) Statewide Totals: ~ 8,000 water systems ~16,000 active water sources

7. 7 For What Sources Can TurboSWAP be used? Ground Water sources already in the DHS inventory New sources must be added to the inventory before TurboSWAP can be used UpcomingUpcoming: –Reduced assessment option for Transient Non- community water systems –Submittal of assessments done by other methods (includes surface water sources)

8. 8 TurboSWAP Demo The following is a series of slides that illustrate TurboSWAP data entry screens and reports. To limit the size of this file, only a few key screens and reports are shown.

15. 15 Source Assessment Task Menu This screen guides the user through the assessment tasks. Each task has a separate button, which when selected sends the user to the appropriate application. The Task Menu also records the status of each task.

16. 16 Task Status These buttons are not available until you have completed previous steps These three tasks allow you to track the status of applications that are outside of TurboSWAP

17. 17 Delineation This next section demonstrates the delineation of protection zones. User answers a series of questions; TurboSWAP determines the delineation method. We will demonstrate the typical default Calculated Fixed Radius method. Map produced by Mapping Tool

23. 23 After the delineation method is determined, TurboSWAP prompts the user to enter data to determine the size of the protection zones. Delineation – Size of Zones Map produced by Mapping Tool (not TurboSWAP)

24. 24 Enter the pumping rate in the units you prefer to use. Note that TurboSWAP calculates the equivalent pumping rate in the other units.

27. 27 This shows the Calculated Fixed Radius equation. No data entry is required on this screen, but it illustrates how the sizes of the zones are determined.

30. 30 Physical Barrier Effectiveness Physical Barrier Effectiveness (PBE) is an indication of the ability of the source and its setting to prevent the movement of contaminants to the drinking water supply. PBE is determined using site-specific information on the aquifer and on the operation and construction of the source. PBE analysis points are based on responses. The points are totaled and a PBE rating is assigned. The maximum number of points a source can receive is 100. Qualitative rating of Low, Moderate or High PBE determined for each source. We won’t demonstrate the PBE section, but will show you the summary screen.

31. 31

32. 32 Inventory of Possible Contaminating Activities The next task is the inventory of Possible Contaminating Activities (PCAs) within the delineated zones. PCAs are activities, businesses, or land uses considered to be potential origins of contamination to a drinking water supply. TurboSWAP includes over 100 types of PCAs separated into four lists. PCA inventory is a ‘presence-absence’ review of whether a type of PCA exists within a protection zone. The review does not identify the number of facilities or the exact locations of the facilities. All sources are required to have the “Other” checklist completed for an assessment; the remaining checklists are optional, but encouraged.

33. 33 Important time saving buttons!

34. 34 This is only one checklist. Enter Y, N, or U in each zone for each PCA.

35. 35 This is one page of the PCA Inventory report

36. 36 Vulnerability Ranking Prioritized list of PCAs in order to determine the PCAs to which the source is most vulnerable Assign points based on the risk ranking of the PCA, the zone in which it occurs, and the PBE Add points and prioritize PCAs from highest to lowest points Source is most vulnerable to PCAs with the highest vulnerability points, AND to PCAs associated with a detected contaminant, regardless of the vulnerability points Vulnerability ranking automated in TurboSWAP based on Delineation, PBE, and PCA Inventory

39. 39 Vulnerability and Assessment Summaries Very Special feature of TurboSWAP User enters summary information, water system description, assessment procedures, etc. The summary information is compiled to produce: –Title page –Assessment summary –Vulnerability summary information for CCR When completed, TurboSWAP produces an assessment report with 8 to 17 pages, without a map.

40. 40 This button is now available

43. 43 Example Vulnerability Summary

44. 44 Sending TurboSWAP Data After assessment completed, user clicks a button and sends the data to DHS (via UCD) Requires an Internet connection without interference from firewalls User can also attach an assessment map, if the map is available in digital format This allows DHS to: –Maintain copies of all assessments submitted via TurboSWAP –Keep track of completed assessments –Report on progress to EPA –Make summary information available to the public

45. 45 This button is now available

46. 46 TurboSWAP Availability TurboSWAP is available to water systems that meet the following criteria: –Medium and large water systems (> 200 service connections) –3 or more sources –System must have adequate hardware and IT capability (Systems that don’t meet these criteria require more support from DHS than it takes to do the assessments ourselves) Systems request TurboSWAP through their DHS district engineers Small systems interested in doing assessments can request assistance from California Rural Water Association
