A study was conducted to evaluate the pond and well water quality at Matiranga Upazilla under very remote areas of Khagrachari Hill District of Bangladesh. The chemical analyses of water included pH, EC, total cations (Ca++, Mg++, Na+, K+, Zn++, Cu++, Mn++, Fe+++, As+++, P+5 and B+3), total anions (CO3--5, HCO3 -, SO4--, NO3-, Cl-), TDS, SAR, SSP, RSC and hardness (Ht). pH values (6.01-7.17) indicated that the waters were slightly acidic to neutral. Waters contained Ca++, Mg++, Na+, K+, HCO3- and Cl- predominantly along with Zn++, P+5 and B+3 in lesser amounts. Mn++, Cu++ and Fe+++ were found trace to very little amount. As+3 and SO4-- were found trace. TDS and SAR values indicated that all water were under `freshwaterþ and `excellentþ class respectively. SSP of most waters were under `goodþ `permissibleþ and `doubtfulþ class. SAR and EC categorized the waters as C1-S1. All waters were found under `softþ class regarding hardness with `suitableþ RSC. Based on As+3, Fe+3, Mn++, Zn++, SO4--, NO3- and Cl- all waters were within the `safeþ limit for drinking.
