Alkalinity, Total (CaCO3) 233.6
It's not great, but it can be worked with. Pre-boiling that water will knock a bunch of calcium and alkalinity out. Read the Decarbonation by Boiling thread on this forum.
Otherwise, learning to use acid effectively will be a skill you develop. Acidification can take care of excessive alkalinity, but beware of overly 'flavorful' acids with this level of alkalinity. Phosphoric acid may be a good choice in this case.
