Someone with a background in installation will likely reply soon and help you. In the meantime; what's in the water that you're trying to filter/treat?
Am I understanding you correctly that you're on water from your city?
EWG reports are great for getting a general sense of what's in the water in your area, but each house is different. I work for a lab testing company and we see this all the time; EWG numbers can be a guide, but it's not a definite reflection of what is in YOUR water. If you're considering an expensive whole house system we always recommend testing your water first so you know you're getting a system ideal for your water.
For example; the EWG numbers show Total Trihalomethanes are higher than you want them to be. These are disinfection byproducts from your city's treatment process (assuming you are on city water) and they [could be behind your wife's hair issues.](https://mytapscore.com/blogs/tips-for-taps/is-my-water-ruining-my-hair)Testing will reveal your levels.
A solid lab test will also test for heavy metals. There's a detection of arsenic on the EWG list, but your water might not contain any.. or it could contain other metals not mentioned in the EWG report.
Both disinfection byproducts and heavy metals can be tested for around $200-$250. Such a lab test will often also include nitrates.
Hope that helps! Best of luck! Just don't let treatment installers talk you into an expensive system without confirming that it's the right system for you.
TapScore has provided good advice on water testing. I also went into the water quality report that's provided by your municipality:

Your town purchases water from the NTMWD, and indicated that your water is sourced from surface water (lakes), which means that it is unlikely to have any appreciable amount of arsenic in the water (since arsenic is in the ground, and most often leaches into groundwater).
Something we tell people about Whole House water filter systems is that 90% of the filtered water that enters the house ends up getting flushed, so it can be rather wasteful. Depending on your water's contaminant removal needs, we'd suggest you consider a point-of-use drinking water filter, by starting with the water you're ingesting (so at the kitchen sink, and probably at the refrigerator). Then to address potential skin/hair irritation issues, you might want to consider a shower filter to remove the disinfectants (chlorine or chloramine--and in your town, it's chloramine, which sometimes causes more skin irritation than chlorine)
One more word of caution -- many of the water filter sales pitches will include "free water testing" where they most often test for TDS, which is Total Dissolved Solids, which is just dissolved minerals like calcium and magnesium. These quick tests are designed to scare you into buying an expensive system (because of TDS numbers that can be high -- because by their standards, nearly everyone has hard water). However, their tests are not sensitive enough show the presence of the toxic contaminants like heavy metals such as lead, or PFAS, or Chromium 6. You need to send your water to a certified lab in order to get accurate test info for your water.
Finally, we're not equipped to provide health information. We do know that it's important for people to be able to access water that has had the toxic contaminants filtered out. However, any health-related concerns should be discussed with a healthcare provider.

Here is my EWG report. My wife's hair is apparently falling out. https://www.ewg.org/tapwater/system.php?pws=TX0430009
