See Water.

Nitrate (NO3-) should to be limited to less than 25 ppm, as otherwise the fermentation may be adversely affected.[1]

Silica (SiO2) is linked to the occurrence of turbidity in the beer and hence should not exceed 25–40 ppm.[1]

Trihalomethanes are byproducts from chlorination and hence are often found when domestic water is used as a water source for supplying a brewery. As THMs are regarded as carcinogenic agents, their concentration should be limited to <10 ppb.[1]
