The priorities are all out of whack. Government-provided water should be government-monitored water (all data for such should be publicly available and accessible immediately).
However, it is important to know how the water is being sampled. If all you ever do is report water quality as it leave the treatment plant, then your data is not useful unless you only use the water at that point. To get good and useful data, you need to sample at various endpoint(house/business locations). You want to randomize these testing locations to avoid selection bias but you also want to get several data points out of them to both eliminate and spot irregularities(i.e. spike in chlorine due to heavy rain, spike in lead due to corrosion in pipes.).
Lastly and perhaps most importantly, would you trust the government if they are telling you the water has no issues?

They have until July to publish the 2020 results.
A well working system would have them be available soon after collection and not matter much (because issues are prevented or fixed upon identification).
