"The analytical results for all ten ofthe Endurance sampling sites in Table 6.5 exhibited pH below the prescribed ANZECC pH range, most likely facilitating the high levels of aluminium and tin in solution (up to 10000 and 51000 times the ANZECC guideline respectively) .
As found for the Monarch and Star Hill Mines, high levels of copper, iron and lead were found in many samples, specifically the stream and creeks samples El, E2, E7 and E8."
"All ground and surface water samples are acidic, with pH values below the recommended range of 6.5 to 9.0 for drinking water. … Groundwater samples from the tailings are more acidic, with pH values of 2.4 to approximately 5. …Surface waters that are impacted by acid drainage have pH values between 2.7 and 5.5. The impact of acid drainage is clear in Conundrum Creek and Ruby Lagoon where pH values drop from approximately 5 to less than 4 where ground water from the tailings enters the creek and lagoon."
