I acknowledge that when so many communities have to deal with short-term and long-term drinking water advisories and all these temporary measures, they lose confidence in their water system, and that is definitely something that needs to be reversed and addressed.
All I can tell you is what we found in our audit, which showed the department's lack of the ability to meet its commitment. I linked it to the lack of a regulatory regime and issues with the funding formula, and hence inappropriate funding to those communities.
Your more pointed question, as to why it has taken so long to address those matters, will have to go to the department.
