SWAP Advisory Committee Meeting
July 8, 1998
Questions and Answers/Comments Summary

  1. Are volunteers going to be used in the program?

    In large population centers such as Shreveport we will probably need the help of community volunteers to inventory potential sources of contamination.

  2. Are military bases going to be included in the SWAP?

    Any military bases having a public water supply would be included. Fort Polk is already participating in the Wellhead Protection Program. Any military base located within a source water protection area will also be inventoried as a potential source of contamination.

  3. Have Brownfield studies been considered relative to SWAP?

    This has not been considered but we will get investigate it. Linda Walker of the League of Women Voters also volunteered to do some research on this topic.

  4. How does the Sole Source Aquifer Program correlate with SWAP and would it influence the size of the protection area delineated around wells or wellfields?

    We feel the current delineations used for the Wellhead Protection Program (which will also be used for SWAP) would be protective of the two Sole Source Aquifers in the state based on our time of travel analysis.

  5. Discussion Summary: There was discussion about the lack of matching between the Louisiana Department of Transportation (DOTD) water well database and the Louisiana Department of Health and Hospitals (DHH) water well database. We felt that DHH should create a field in their database to include the DOTD registration number for new wells drilled, and that DOTD should survey new wells with GPS instruments that record accuracy in the 1 to 3 meter range. Currently, they use hand held units with an accuracy of approximately 300 feet. This does not seem reliable enough where there are clustered wells in a wellfield. Hopefully the Source Water Assessment Program will provide information that will aid them in better matching their databases as there is different information in both databases that is valuable.
