Tap water taste - new to the area. Do we need a water treatment system? Water filter? Howdy neighbors!

We are in the process of moving to Elk Grove, and have an issue with the tap water.  It is quite flavorful and wretched (compared to the pacific NW).  Is this common?  What do y'all do about it?

We are investigating hard-water treatment systems, but the water testing kit from home depot proclaims our water is not hard (it just has pesticides, lead, nitrites, and nitrates in it).

Do we simply need a whole-house filter?  We definitely will get a drinking water filter, either way.
