Title: Leah Walker


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

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
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
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
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
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
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
  • Upcoming
  • Reduced assessment option for Transient
    Non-community water systems
  • Submittal of assessments done by other methods
    (includes surface water sources)

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.

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.

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.

Delineation Size of Zones
After the delineation method is determined,
TurboSWAP prompts the user to enter data to
determine the size of the protection zones.

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

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.

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 wont demonstrate the PBE section, but will
    show you the summary screen.

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

34
This is only one checklist. Enter Y, N, or U in
each zone for each PCA.
35
This is one page of the PCA Inventory report
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

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.

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

TurboSWAP Availability
  • TurboSWAP is available to water systems that meet
    the following criteria
  • Medium and large water systems (gt 200 service
    connections)
  • 3 or more sources
  • System must have adequate hardware and IT
    capability
  • (Systems that dont 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
