What does haloacetic acids mean in practice?
Laboratories report defined sums such as HAA5, so the result must be matched to the exact analytical scope.
When does it matter?
They do not necessarily behave like volatile THMs during boiling, and formation depends on precursors, pH, dose and contact time.
Which solutions are related to it?
Reduce organic precursors before chlorination, optimise disinfection and use suitable carbon or RO where needed.
