Should IDSE samples be collected during the warmest month or during the month of highest DBP levels?
IDSE samples should be collected in the month of peak historical TTHM/HAA5 formation. If the system does not have adequate historical data to determine this, the samples should be taken during the month of warmest water temperature.
