Water hardness levels and tolerable limits vary widely with respect to suitability for the various domestic uses and so also the effects. It is at this background that this paper sets to carry out a comparative characterisation of forms and levels of water hardness of domestic water intake sources in Dutsinma town. A combination of stratified and purposive sampling was used in selection of the sample sources. Seven (7) hardness parameters were used to analyse forms of water hardness; Two divalent cations (Ca2+, Mg2+ ), two monovalent cations (K+, Na+), for pseudo hardness and three hardness anions (HCO3-, SO4-, and Cl-) to determine carbonate (temporary) and non-carbonate (permanent) hardness. The Cations concentrations in mg/l were analysed using Atomic Absorption Spectrometric (AAS) method, while the anions were analysed using spectrophotometric method. The calculation method was used to express all the concentrations of the cations and anions in mg/l as CaCO3 from which ten (10) different forms of hardness were characterised as follows; calcium hardness (CaH), magnesium hardness (MgH), total hardness (TH), carbonate (CH), sulphate (SO4H), chloride (ClH), non-carbonate (NCH), potassium pseudo (KPsH), sodium pseudo (NaPsH) and total pseudo (TPsH). Results of the analyses revealed prevalence of high to very high levels of hardness of the various forms across the sources as follows; TH (66%), CH (64%), MgH (62.5%), CaH (59%), ClH (55%), TPsH (52%), NaPsH (48.27%), NCH (34%) and KPsH (0%), Most of these forms of hardness with high levels were groundwater sources (boreholes and wells) as follows; CaH (BH, 100%, Wl, 75%), TH (BH, 87.5% and WL 87.5%), CH (BH, 100%, WL, 75%), ClH (87.5% in both BH and WL), NaPsH (WL, 87.5%, BH, 75%), TPsH (WL, 87.5%, BH, 75%). On the other hand SO4H, predominated in surface sources as more (62.5%) recorded high to very high hardness levels. Finally MgH and NCH predominate in pipe water sources which recorded very high and high levels; MgH (75%), NCH (80%). However, All (100%) of pipe water sources are soft to the following CH, SO4H, ClH, NaPsH and TPsH. This study provides a more reliable understanding on the implications of specific forms of water hardness on domestic water uses, their health and widely spread effects on other aspects of the household. To this end more precise and priortisation decisions can be taken in dealing with water hardness challenges in the study area.
