GROUNDWATER QUALITY FOR DRINKING BY GOLD-STANDARD AT HIGH-ALTITUDE AREA, TAIF, KSA "VISION 2030 G"

Abstract

This paper was for Groundwater (GW) quality for drinking by gold-standard (GS) athigh-altitude (HA) area, Taif, KSA "VISION 2030 G", GW samples contained turbidity,resulted high in samples (6 and 10); (0.03 and 0.018). Public health (PH) were had declinedwithin GS. Electric conductivity (EC) were within the optimum value, total dissolved salts(TDS) were had lowest value. Total hardness (TH) were of more than (300–500) mg L−1,Chloride (Cl−) ranged from (18-1759) mg L−1 with 30% and 70% samples. Sulfate (SO42−)ranged from (33-2245) mg L−1 with 90% falling above GS, Nitrates (NO3−) ranged from (0–60) mg L−1 with 80% falling below GS. Bacterial types revealed both Gram-positive andnegative were not in samples (1, 2, 6 and 7), both Gram-positive and negative were presentin samples (5, 8 and 9). The arrangement of colony count were in samples (9, 1, 8, 6, 7 and5), that was ranged the colony from (550-15) / mL. The common bacteria were isolatedincluded Staphylococcus Species (Staph. Spp.), Micrococcus Spp, Escherichia coli (E. coli)and Klebsiella Spp. The conclusion were discharged from the results, that did not agree withGS to the community use. The most examined GW samples for drinking water (DW) did notagree with GS, bacterial quality did not accepted from GS, will affect PH. Therecommendation were directed to "MOH", to follow up GW for DW through GS at HAarea, so could using for human as DW without any harm and did'not affect PH.
