Identifikasi Kualitas dan Analisis Fasies Airtanah Dangkal di Desa Bantan Sari, Kecamatan Bantan, Kabupaten Bengkalis, Provinsi Riau

Bantan Sari Village is one of the villages on Bengkalis Island, located close to the northern coast of Bengkalis Island. This village consists of only one formation, namely the Old Surface Deposits Formation (Qp), which has swampy areas and acidic peat conditions. The purpose of this study were to determine the distribution and direction of groundwater flow, the feasibility of physico-chemical groundwater quality, and the condition of groundwater facies in Bantan Sari Village, Bantan District, Bengkalis Regency, Riau Province. The parameters tested were color, taste, odor, dissolved solids (TDS), electrical conductivity (DHL), pH, Fe and Mn. The research method used is the three-point method to determine the direction of groundwater flow, laboratory analysis method to determine the physico-chemical quality of groundwater and kurlov, stiff, piper methods to determine groundwater facies. Based on the research results, 14 dug wells were obtained. The center of groundwater distribution is located at stations 11, 10 and 3 of the study area. The color of groundwater in the study area is clear (36%), yellow (7%), brown (21%) and reddish brown (36%), the taste of groundwater is tasteless (64%) and brackish (36%), the smell of groundwater is odorless (57%) and smelly (43%), solute (TDS) value 107 mg/l - 1110 mg/l, electrical conductivity (DHL) value 107-1110 ?S/cm, pH value 6.49-6.71 at all stations, Fe value 0.3 - 5.34 mg/l, Mn value 0.1 - 0.14 mg/l. Analysis of groundwater facies using Kurlov diagrams, stiff diagrams and piper diagrams which show 3 types of groundwater facies in the study area, namely Cl + SO4 facies, Na(K) HCO3 facies and Na(K) Cl(SO4) facies. Based on the results of the research, there is only 1 dug well station, namely station 1, whose water meets the quality standards based on the Minister of Health Regulation No.492 of 2010 and the Minister of Health Regulation No.32 of 2017 as drinking water or clean water.
