My Water Report

I get my brew water from Lawton, Oklahoma. This is the basic water analysis information from their website and reports. Any one care to take a look at my water profile and give any advice on what exactly I should do to improve it. I brew mainly pale ales, wheat ales, and the occasional IPA. Any advice would be great, also I don't know what most of this means.

As a brewer you'll want to know the cloride and sulfate levels as well. Send off a sample to Ward Labs. Hardness is bit high as is alkalinity but both are manageable.
