More clarification on Cougar Energy incident. Now confirmed that one test was above the safe drinking water standard. Not sure when this test was conducted. This is from the DERM statement attached to the CXY announcement to the ASX today-
"All of the sampling carried out to date by both Cougar Energy and DERM indicates that benzene has only been detected in one bore (monitoring bore 37) at a maximum concentration of 2 parts per billion (above drinking water guideline of 1 ppb)."

So, we finally find out that there was one confirmed case of water pollution.
There is more on the DERM statement worth reading that is not on DERM's website yet.
