    Suitability assessment of shallow groundwater of a typical coastal aquifers for irrigation use: A water quality index model approach
    (U. P., 2015) Uzoije, Atulegwu Patrick; Uche, Cosmos C.; Enwereuzo, Uzo; George, Raphael
    Shallow Groundwater of a coastal aquifer has been intensively used as a source of water for irrigation farming in the Niger Delta region of Nigeria. To assess the usability of this water for irrigation use, twenty locations at buguma city were mapped out and five water wells were sampled for each location using simple random sampling technique. Each sample was analyzed for the cations(magnesium(Mg2+), sodium(Na+), potassium(K+),calcium(Ca2+)),anion(nitrate ion(N03-)), trace elements(cadmium(Cd), iron(Fe), and zinc(Zn)and other phsico-chemical parameters(Salinity(SI), electric conductivity(EC) and pH) adopting standard methods. Based on the analyzed parameters, irrigation water quality parameters (RSC, SAR, %Na and %MR) and indexes(Kelly index(KI), Permeability Index(PI) and the Canadian water quality index(CWQI)) were calculated .To assess the usability of the shallow groundwater, results of the Water quality index models and other calculated irrigation parameters were compared with the standards. On the average, virtually all the sampling locations except Ombu, Igba and Jackreech were unsuitable for irrigation use.
