It looks like this water is fairly well suited to brewing American Ales. The magnesium content is a little high, but passable. The sodium, sulfate and chloride levels are kind of steep but not unbrewable. A moderate dilution of about 50% wouldn't be a bad idea. That dilution would drop the calcium a bit too low and you might consider adding either CaCl or gypsum depending on the brewing goals. In general, I would only consider gypsum when brewing a fairly hoppy style since the sulfates are high as is.
If you're brewing a very pale beer, then 0.1 mL of 88% lactic acid per gallon of mash water is suggested to counter the alkalinity. I'd suggest adding 0.3 grams of CaCl per gallon to bump the calcium back up after dilution.
This water would do a good job for an American Brown or Amber without much adjustment at all. A little more alkalinity might be needed for a black beer, but I would try it without first.
Its not a terrible water, but its going to be tough to brew lighter or delicate styles with the high Na, Cl, and SO4.
