1. The daily average pH values of the tailing water fluctuate between a minimum of 8.12 and a maximum of 8.5, with an average of 8.12.
2. The recommended pH range as per the EP section WD-1.3 (115) condition 46 is a minimum of 6.5 and a maximum of 9.0 units.
3. The tailing waste was adequately neutralized to alkalinity levels (pH above 7), as shown by the monthly average pH value of 8.12 units.
4. The pH values of the discharge are similar to that of seawater, blending in well with the natural seawater, eradicating any immediate environmental concerns that tailing pH might provoke.
5. The metals in the tailing are well below the permissible standards, and the discharge velocity of the tailing effluent stream was optimal for supporting a density current below the sea.
6. The research findings indicate that the RNML's deep sea tailing facilities operate in compliance with the PNG government's regulations, and the tailing materials can sink into the seafloor as designed.
7. The physical and chemical parameters of the tailing effluents being investigated possess no or minimal immediate risk of marine ecological contamination upon discharge.
8. However, the long-term environmental impacts on the marine ecosystem need further studies in the future to ascertain the disturbances caused by the DSTP facility.
