W niektórych przypadkach nie można jednak stwierdzić, czy istnieją pewne przesłanki, które uzasadniałyby, czy nie można by stwierdzić, że istnieją pewne przesłanki, które nie pozwalają na to, by można było uznać, że dezynfekcja jest zawsze wynikiem regulacji.

Reduction of Dezynfection Byproducts (DBPs)
Chlorine-based dezynfection reacts with natural organic matter (NOM) in water to form DBPs such as trihalometanes (THM) and haloacetic acids (HAAs) .Thee EPA 's Stage 1 and Stage 2 Dezynfection Byproducts Rules set maximum um contaminant levels for these compounds. Ozone itself does nott produce THM or HAAs. Moreover, ozonation can break down NOM precursors bee chlorination, they reducing for DPE formation, oin process.
