Despite the fact that the number of plants and factories of bottled water is increasing rapidly, there has not been any serious intention on the part of governmental bodies to take action against the unlicensed factories. This has led to the quality of bottled water in many cases violating the required standards of chemical and physical properties for the potable water, which threatens the public health. The aim of this paper was first, to investigate whether if these bottled water do really meets the international and Libyan standards of bottled water, and second to point out the actions taken by the responsible authorities as well as other related governmental/non-governmental organizations. The paper examined four random samples of bottled water sold in Tripoli during January 2019 and measured some of its physicochemical properties, such as total dissolved solids (TDS), pH, sodium, potassium and calcium. The results indicated that all the experimental values were different from what was written on the samples’ labels. The percentage of these differences ranged from 2% to 650 %. The statistical data of TDS (labeled-measured) was found to be 78.725 mg/l with a standard deviation of 33.91758 mg/l, and t-test with p = 0.019 (P ≤ 0.05), which means results are significant. It was also observed that all samples violated the Libyan standards in not providing all the required data on their labels; 25% of samples do not include water source, 50% of samples do not mention the source of the water, 75% of samples do not mention license number, and 50% of samples do not provide any written statement regarding the storage conditions, which means that all the samples must be withdrawn from the market without the need for chemical or biological testing.","PeriodicalId":36321,"journal":{"name":"Water Conservation and Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49551081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It lies between latitudes 6°15' and 6°35'N and longitudes 7°40' and 8°15'E. A total of twenty one (21) groundwater samples were collected and analyzed. Parameter analyzed were; EC, pH, TDS, Cl¯, Na , Mg , NO ¯, SO ¯, Ca , HCO ¯, K , CO ¯ these parameterwere analyzed using American Public + 3 Health Association standard method. Various hydrogeochemical approach and model were used to assess chemical quality of groundwater within the study area. These include; Gibbs, Mg /Ca . End-member, Diamond 2+ 2+ field of Piper and Parson plots were used to indentify major source influencing groundwater chemistry within the study. Finding, from Gibbs plot and Mg /Ca against Mg /Na revealed that rock dominance is the major 2+ 2+ 2+ + process that control groundwater chemistry, while End-member plot showed that silicate and carbonate weathering are the two weathering process that influence groundwater chemistry within the study area. Diamond field of Piper by Lawrence and Bal-Subramanian modified, revealed that groundwater fell within High Ca + Mg & SO + Cl. Parson plot revealed that 65 % of groundwater fell within Ca - Mg – Cl water type, while 4 35 % fells within Ca - Mg - SO . Relationship between TDS vs TH plots showed that groundwater samples fell 4 within soft - fresh water category. The results of the geochemical survey reveal major ionic components trend in other of Mg>Ca>Na>HCO3>SO4>Cl, result reveal that there is no particular trend of ions movement in groundwater.","PeriodicalId":36321,"journal":{"name":"Water Conservation and Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46775777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The city of Faisalabad has over 4 million population. Groundwater is the main source of drinking water in Faisalabad. The groundwater quality should be regularly monitored in order to cope with the drinking water quality issues. An attempt has been made to understand the groundwater quality by using water quality index (WQI) at Chokera area, Faisalabad, Pakistan. It is a technique of rating water quality, is an effective tool to assess spatial and temporal changes in groundwater quality. Sixty groundwater samples were collected and analyzed for physico-chemical parameters using standard method of analysis. From the data obtained, the water quality index was calculated by adopting the method developed by Tiwari and Mishra. Water quality index rating was carried out to quantify overall ground water quality status of the area. The WQI index of the same has been calculated and the values ranged from 73 to 272. The WQI values from present study indicate the very poor water quality in the area. The analysis reveals the fact that the groundwater of the Chokera area needs a degree of treatment before consumption and needs to be protected from further contamination","PeriodicalId":36321,"journal":{"name":"Water Conservation and Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48673991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
