Not sure what you mean by additives, unless you're talking about chlorine. If that's what you're talking about, I've got no idea what the level of chlorine on your list actually works out to for brewing as far as whether it matters. Does your water taste like chlorine? I'm not sure if the free chlorine levels means that they definitely use chlorine, some places have switched to chloramine. To be safe, chlorine can be removed with an RV water hose and charcoal filter.
If you're talking about the rest of the report, everything looks pretty good. For extract, all you really need to worry about is chlorine and whether you have more than 50ppm calcium, but you've got that and most extract probably does already too. The rest of the details don't matter until you start mashing, but when you do your water looks pretty good. Alkalinity is low enough, and everything else is in a low spot in the good range. Nothing there to worry about!
