And now for a few basic chlorine testing facts:

  • Test kits containing only OTO as their chlorine testing reagent will test for total chlorine only.
  • Free chlorine testing requires DPD-1. Adding DPD-3 to the sample after adding DPD-1 allows a person to test for total chlorine.
  • The USEPA has set the maximum contaminant level for chlorine in drinking water at 4.0ppm. This limit applies to both free chlorine levels and total chlorine levels.
  • When testing for parameters other than chlorine, some test kits will require the use of chlorine eliminating agents such as sodium thiosulfate before testing can take place.
  • Water containing the same amount of total chlorine as it does has very little or no free chlorine.

  • The difference between the free chlorine level and the total chlorine level equals the chloramine concentration.
