(aa)

in the catchment area used to abstract water for human consumption purposes, and

(bb)

as a result of abstraction through the public water supply system,

at a concentration or value which would (whether in conjunction with another parameter in the water or otherwise) constitute a potential danger to human health,

(ii)

where a parameter from the list of parameters to be monitored under Part B of this schedule can only occur as a result of the treatment technique or disinfection method, that technique or method is not used by Scottish Water, or
