Are there more in depth contaminant tests that can be performed in a customer’s home than OTO?
Not feasibly, most other tests for organic chemicals or heavy metals require testing by a spectrometer or by atomic absorption. Both methods are very accurate and require very costly equipment. Accurate and specific water analysis can only be performed in a laboratory. The best method of showing a consumer that there are other chemicals in their water is to obtain a copy of the water utilities annual water quality report, by law they have to provide it. The OTO (orthotolidine) test gives a good visual of the levels of chlorine in the water and the filters ability to remove it.
