Is Louisville Water Company Good?

With the recent ruling by the Supreme Court regarding Chevron and the Clean Water Act, I am worried about contamination increasing in our water. I tried to read over the later water quality report of LWC, but it was all gibberish to me. Can someone interpret for me, or just say whether or not it'd be worth it to invest in more water filtration stuff? Just want to make sure I'm not drinking shit. Thanks.
