      Dye test turns Columbia creek green

      The dye made the water in Flat Branch Creek turn green.

      Columbia Public Works crews had a colorful way of testing some pipes.

      They used a non-toxic green dye to check for any connections between the cityâ??s sanitary sewer system and storm water system.

      Sewer water needs to go to the cityâ??s waste water treatment plant.

      Storm water is supposed to flow directly into creeks and streams.

      The dye made the water in Flat Branch Creek turn green.

      Test results show there are no direct connections between the 2 systems.

      They did find some leaky pipes.

      Columbia Public Works spokesman Steve Sapp said, â??Itâ??s not a bad water quality issue. It does raise capacity concerns. Itâ??s something that we determined. We are glad that we didnâ??t have a direct connection between storm water and sanitary. The infiltration is something that we can fix easily.â??

      Sapp said the green coloring lasts about 24 to 36 hours.
