Water companies commitment to good water

As a Civil Engineer in Australia who has worked with town water supplies, I find the stories I hear about water quality amazing.
The issue of lead in the water is mind boggling.
You may find this information interesting and the source website even more so.
I am keen to hear feedback.
From USA water quality plans

National Association of Water Companies (NAWC) new five principles for advancing water equity with 5 Water Equity Principles
The principles, are summarized as follows:

Everyone should have access to water that is safe, reliable and affordable.
NAWC members are committed to achieving water equity, which means that everyone should have access to safe, reliable and affordable drinking water. As a nation, we must advance water equity to ensure customers of all income levels have access to high-quality water.
Focus on the customer. For NAWC’s water utilities, the customer is the top priority.
NAWC members have a customer-first mentality and demonstrate a long-standing commitment to water equity by creating a variety of customer assistance and conservation programs to help customers who struggle to pay their bills.
Never compromise on providing safe and reliable water. It is not enough to be low cost.
Water must also be high quality and there when you need it.
Invest in communities. The 10 largest NAWC member companies invest nearly $3.7 billion in their water systems annually.
These investments keep rates stable and quality high. NAWC’s utilities strive to lift up communities where we live, work and serve by investing in those communities to create long-lasting positive change and promote public health.
Develop partnerships and encourage water system consolidation.
The drinking water sector is extremely fragmented, with over 50,000 water systems across the US.
More than 90% of systems serve fewer than 10,000 people and half serve fewer than 500 people.
Water system fragmentation increases costs and often decreases water quality, perpetuating environmental injustice and causing disproportionate harm to low-income communities.

This all sounds like a motherhood statement, something which will look good but never happen

I'm going to really disagree with some of this point, here in Denmark with a population of 5.5 million we have about 400 water companies  which averages around 14k per company, but some serve many many more and most many less. It doesn't matter which company serves your water the requirements for that water are the same, the local village lost potable water for 2 weeks last year (we didn't we're actually on a different company) as the borehole needed to be re-drilled as it had become contaminated with bacteria, it wouldn't have mattered that it as a small waterworks serving only a couple of thousand people or a national one, the contamination problem and solution would still be the same.
If you so wish you can work out which borehole your water comes from and read the last 50 years worth of data on it, including what pesticides, herbicides, bacteria are present how much is present and how much water has been extracted. All of Denmarks water is from boreholes and none of it is chlorinated.

We have weird problem in our city in that the school in neighborhood that aren't low-income/non-white all still have pipes that causes elevated lead in the water supplies. But in the richer/white neighborhood in our city and in neighboring cities they have removed all the old piping decades ago and aren't plagued with said problem. For decades now they have been asking the school district administration to removed the old pipes in the low-income school vs just promise to install a filter that is either never installed or they change the filter too infrequent that it cant do it job, and then the blame a sub-contractor and never take responsibility even though it has been decades.  Why are they still promising to use temporary stop-gap solutions when this problem has been here for half a century.

I am however glad that our metro area water supply is one of the best in the country.
