FYI, this should be added to OP:
First, I should disclose that I work in the Water Quality department of a major California water company so I am literally defending myself here but this site seems to be tracking your water quality versus the Public Health Goal (PHG), which is intended to be an ambitious goal that is often below the detection limit in the laboratory (meaning there isn't a laboratory method that measures that low). I just did a quick glance to confirm that the numbers on the website do match what you'd find in the publicly available Consumer Confidence Report but just comparing against the PHG and not the legal limits seems to be confusing for the consumer.....
What you should actually be worried about is if you water quality is above the Maximum Contaminant Level (MCL) which does not seem to be listed on this site. While the PHG is the level at which they can confirm that there is no health risk at all, the MCL is tje limit at which if you drink that water everyday for 80 years then you have about a 1 in a million chance of developing cancer from it. The MCL is also the limit that is enforceable.
And for the poster that mentioned being safe due to having a well, unfortunately that's going to have worse water quality due to not being treated, tested, etc. We get almost all our water from wells and it's usually pretty nasty in its raw form.
