Free Cl was measured using a colorimetric method (DPD) with a
HACH Pocket Colorimeter II. Turbidity wasmeasured with a turbidimeter
HACH 2100 N. TOC concentrations were obtained using the carbon
analyzer SIEVERS 5310 C from General Electrics completed with an
automatic sample passer SIEVERS 900. Bromide was analyzed using
method MA 303–Ions 3.1 of the Centre d'expertise en analyze en
Environnement de Québec. Analysis of HPC was based on the Pour
Plate method using Total Plate Count Agar (IDEXX) incubated at 35 °C
for 48 h. This method is described in the Standard Methods for the
Examination of Water and Wastewater, 19th edition (AWWA, 1999).
