6.11 Dip Slide Testing

Dip strip testing – Field Instructions:
Dip strip testing must be performed for each and every non-make up water sample taken.
Procedure:
1. You will need one Dip Strip per tower being treated by CHC.
2. Open the Dip Strip and remove the test strip from the foil package.
3. Submerge the test strip in the water from the tower for three (3) seconds, being careful not to
submerge in a high turbulence stream; this could damage the test strip.
4. Remove the test strip from the water and sling off any excess water by waving the strip from side to
side.
a. DO NOT ALLOW THE TEST STRIP TO TOUCH ANYTHING AT THIS POINT!
5. Place the test strip into the supplied zip-lock bag.
6. Label the bag with location, sump and date.
7. Place the test strip in a location out of direct sunlight for a period of 48 hours. This location must have
a stable temperature in the range of 77-95 degrees F.
8. After 48 hours, compare test strip to the results comparison page supplied with the Dip Strips.
9. Record the test results in Ulysses.
10. EcoWater CHC requires pictures of any Dip Slide that shows a count larger than 10,000
11. Samples that have a count greater than 100,000 will require a more in-depth test.
a. These tests can only be performed at our lab.
