I'm not saying that first world countries don't have sporadic issues with water supply. They do. What I'm arguing is that if as a general rule you can't trust the results when your local officials testing the water quality, then your country has failed at meeting the standard for a first world country. I agree that "you have failed" would have been better framed as "your country has failed you". That was my thinking, but the sentence did not make it clear. Yes, the UN SDG6 is a goal for 2030 - for developing nations. If you haven't already met this goal, you are a developing nation, not a first world nation.
