“There have been a number of low-level [pesticide] detections in streams since commencement in 2005 and wherever possible these are investigated by the relevant Department. However none of the levels detected in streams have reached anywhere near the national ‘Health Values’ set by the National Health and Medical Research Council (NHMRC) and it is very uncommon for such contaminants to be detected at all in community drinking water supplies.” - Dr Roscoe Taylor, Director of Public Health, 16.02.10 12:44 pm.
I was very interested in the above comment from Dr Taylor, and would like to ask some questions:
Dr Taylor says “there have been a number” of positive tests for pesticide contamination in Tasmanian “streams” and drinking water supplies since testing began in 2005.
How many times is “a number,” in total?

And where?
Dr Taylor says “it is very uncommon” for pesticides to be detected in community drinking water supplies.

How many times does “very uncommon” mean in total since 2005?

And where?
Dr Taylor also says that detections of pesticides in Tasmania’s water are “investigated by the relevant department”.

How many investigations have there been in total since 2005?

And how many prosecutions have resulted from those successful identifications?
The way I hear it, the actual numbers are something like this:

Pesticide detections in rivers and creeks: 100+
Pesticide detections at Launceston’s drinking water plants: 13
Pesticide detections at Hobart’s main drinking water plant: 3 or 4
Pesticide detections in rivers and creeks that ultimately supply town or city drinking water: 50+
Baseline Monitoring Program: Testing once every 3 months, and after floods
Investigations: dozens
Successful identification of culprits: 3 or 4
Prosecutions: 1 or 2
