the surface water chemistry of thiruvananthapuram museum lake was carried out in the period of february 2013 to january 2014. correlation study of the parameters and overall ccme wqi (canadian council of ministers of the environment water quality index) was also prepared in the study for the lake water. the parameters analysed are cations such as ca2+, na+, mg2+ and k+ and the anions like po4-,...

The water quality of bodies in Huasteca Potosina was assessed by the National Sanitation Foundation Water Quality Index (NFS WQI) depending on nine parameters include physical, chemical, and biological properties. obtained at sampling site 50-90 NSF-WQI range shows medium quality. Results revealed that Moctezuma River Tanquian de Escobedo has low with a score 50, Tancuilin Axtla Rivers have goo...

The present study was mainly proposed to investigate the quality of groundwater for drinking in Kifri District. main aim this identify some pollutants using two types indexes which are: Nemerow’s pollution index (NPI) and Water (WQI). samples were collected from 36 stations (deep wells) analyzed seven physico-chemical parameters including EC, TDS, pH, TH, TA, Ca+2 andSO4-2; as well as, results ...

Abstract The Water Quality Index (WQI) is a single, deferential metric for describing the state of water quality as whole, which aids in selection effective remediation strategies. Fifteen surface samples were taken from Euphrates AlHaydria neighborhood AL-Najaf (Iraq). Various physicochemical parameters, including pH, total dissolved solids (TDS), calcium, chloride, sulfate, and electrical con...

Fuzzy Water Quality Index (FWQI) was applied in order to assess the degree of drinking water resources in Yazd province, Iran. Thisstudy has also offered the creation of a new fuzzy water quality index (FWQI) to evaluate this tool’s applicability. 12 chemicalparameters including toxic and non-toxic heavy metals measured in 71 groundwater samples collected from drinking water resourcesin rural a...
