As expressed in the analysis, the performance of <br />the PSSA embankment will not be affected by potential failure of the ADR water lines. Despite <br />this conclusion, as suggested in the analysis, the embankment will be regularly monitored to <br />minimize the likelihood of any potential impact on stability, should a leak develop.
