pH 7,8
Alkalinity 0,68 mmol/l
This is really the most important parameter especially when it is small (< 1).
The problem here is that the expression is in millimoles but there is no specification as to millimoles of what. If it is electrons then the alkalinity is 0,68 mEq/L which is nicely low. If it is mEq/L calcium carbonate or calcium oxide then the alkalinity is 2*0,68 = 1.36. As you gave a number in dH in the OP I suspect that is it. You can brew a lot of beers with alkalinity this small without any treatment though you can improve them with modest treatment. See

As discussed in an earlier post.
Kloori (Cl2), free? <0,050 mg/l
This is the amount of chlorine in hypochlorite ion (a result of addition of chlorine to the water).
Kloori (Cl2), whole? 0,069 mg/l
This probably means the total chlorine plus the amount of chlorine found in chloramine. Very small numbers in either case and not something you probably have to worry about. Can you smell any chlorine? If not then don't worry but if you can see:

Ammonium (NH4) <0,0060 mg/l
Actually good for yeast but here the amount is so small as to be insignificant.
Fosfaatti (PO4), whole <0,0060 mg/l
You will seldom find appreciable amounts of this as calcium phosphate is extremely insoluble (your teeth and bones are made of it). This amount is insignificant.
hardness (Ca + Mg) 0,58 mmol/l
The second most important parameter for brewers. As anticipated in the earlier post this number is not far different from the alkalinity. In more usual terms it is 2*0,58 =1,16 mEq/L (comp 1,36) for the alkalinity. The difference is the sum of the equivalences of the choride and sulfate ions - here 0,26 mEq/L which is not much. This is pretty nominal water.
Alumiini (Al) 14 μg/l
Left over from the chemicals added at the water treatment plant to precipitate silt, bacteria, sand.... Not enough to even consider.
As discussed in the previous post.
Summary: pretty typical stuff. Chlorine/chloramine low enough that you should be ok to use as is but if not use metabisulfite to lower chlorine/chlaoramine even further. Alkalinity is a little, but not atypically, high. Use with 1:1::tap:RO dilution and follow Primer recommendations or neutralize with acid.
