SO4---------------------24
CO3---------------------78
Alkalinity----------------64

That water is...really nice. Use a simple spreadsheet like Bru'N Water. I was resistant to it too, but it's very easy. You won't need to modify much.

I just took a look at the spread sheet that you recommended, it seems like a really great tool! I am curious though, what makes the water I described nice? Is it nice in that it can be easily modified, or does it have some stuff in it already that is beneficial?

Really balanced, easily modified. For example, if you were going to make a pale ale, just a smidge of calcium chloride and you're good to go. Does your municipality use chlorine or chloramine?

I am not sure to be honest which they use actually. This is good news though it seems, I am not quite at the point yet where I am ready to start playing with my water chemistry, still need to nail down my mash efficiency issues, but i found this report today and wanted to know what I was already working with! Thanks for the information!

The chlorine/chloramine thing is important to know. Chlorine will just boil off during your brew day. However, chloramine is harder to get rid of. I just use Campden tablets and that's super easy. I know it's tempting to leave water for after mash efficiency is worked out, but I'd caution against that. I was having mash efficiency problems BECAUSE of my water. I had low calcium in my water and that is a necessary cofactor for the amylase enzymes. Yours is pretty low too (not as low as mine was) so it's something as simple as adding a teaspoon of Calcium chloride would go a long way. It would potentially help your efficiency and it will help your hops "pop" more.

I did some quick research and we actually use chlorine dioxide to treat our water here. In my last brew, I only had around 55% efficency from my single infusion mash using a batch sparge, so I might experiment with adding some CaCl to my water. Where do you get your food grade CaCl from?

Chlorine should be treated before using too. Chlorine will boil off, but you're not boiling it before you're mashing with it (or at least I know most breweries don't boil their water before mashing..that I know of).

I do run my water through a Breta filter before it goes into the mash and it is advertised to remove 99% of chlorine, I do wonder what else it could be removing too...

Edit!

It appears that water filtration through activated carbon such as a Brita filter removes an average of 90% of the calcium in the water, that could be a problem!

I just got mine from my LHBS. I think Whole Foods carries it too.
