Well I am no water guru. However, Palmer suggests keeping water within these mineral constraints (obviously varying dependent on the water style you are seeking):
Ca: 50 -150
Mg: 10 - 30
HCO3: 0 -250
Na: 0 -150
Cl: 0 - 250
SO4: 50-150

looks like your Ca is a little low, as is your Mg. However you need to determine the type of water you are looking for based on what you are brewing. All said, I am sure it makes good beer. On that link you can check out some of the various types of water and composition
