However, treatment plants for sanitary sewerage were typically not designed or constructed to treat combined sewer flows during major rainfall events. This lack of initial treatment capacity and the growth of collection systems due to urban sprawl have led...

Total sulfides are measured in the field from a wastewater sample collected from the sewer system using another version of the LaMotte Pomeroy test kit. The measurement of total sulfides in the field indicates the magnitude of the sulfur species present...
