Notes: (1) Samples need not be analysed for lead if there are reasonable grounds for believing that lead pipework or solder is not present in the plumbing of the property or that naturally occurring lead is not present in the water. (2) Samples need not be analysed for nitrate if there are reasonable grounds for believing that nitrate levels in the locality concerned are below 25 mg NO3/l. (3) Samples should not be assessed qualitatively for taste if there are reasonable grounds for suspecting that the water may give rise to a health hazard. (4) The sum of the detected concentrations of fluoranthene, benzo 3.4 fluoranthene, benzo 11.12 fluo ranthene, benzo 3.4 pyrene, benzo 1.12 perylene and indeno (1,2,3,-cd) pyrene.
