The Administration should give consideration to the recording
of other parameters in addition to those required (thermotolerant
coliforms, total suspended solids, BOD5 without nitrification,
COD, pH and residual chlorine) with a view to future technological
development. These parameters include total solids, volatile solids,
settleable solids, volatile suspended solids, turbidity, total organic
carbon, total coliforms and faecal streptococci.
