When CO2 is dissolved in water, carbonic acid is formed and this is very much unstable. Soon it's formation carbonic acid changed to HCO3. Thus bicarbonate is formed. In water chemistry, ions are present in pair form ( anion and cation ). Bicarbonate has great affinity with Na and Ca ,and thus NaHCO3 and CaHCO3 are formed. However presence of F and SiO2 are depend upon natural ( mineral water interaction ) and anthropogenic sources along with dissociation and dissolution processes.in addition to this, various other factors are responsible.
