2015 August – Pentland (Queensland) – Mercury
Mercury Detection– Pentland: Whilst preparing this report it was noticed that there had been a very small detection of Mercury (0.0013mg/L– [0.001mg/L to two significant figures]) in August 2015, this was reported to DEWS 30/11/16. All preceding and subsequent tests showed no detection at all (below threshold) and no explanation can be given for the result. The external tester has now reviewed their reporting of non -compliant results and a more thorough internal evaluation process has also been introduced.
