This looks to me like it needs plenty of work.
Hardness = 250 ppm as CaCO3
Alkalinity = 220 ppm as CaCO3
Sulphates = 85 ppm
Chlorides = 35 ppm

That looks like a load of bollocks to me!
more or less meaningless for brewing! . . . . Sorry

Sorry, Grumpy head on.
Forget hardness, at least it means you have sufficient calcium such that you do not have to supplement it
Alkalinity, blooming high, need to reduce it to below 100-125 for dark beers and beers with a moderate level of crystal in it.
Sulphate and Chloride, just greater than 2:1 so good for hoppy, crisp, dry beers, if you want to reverse it use more hydrochloric acid than sulphuric acid to reduce the alkalinity, otherwise use a 'balanced' amount of sulphuric and hydrochloric acids to keep the 2:1 ratio . . .
It's not suitable for treatment with AMS/CRS and DLS/DWB
