Bu çalışmada, Afyonkarahisar İli Şuhut Ovasının jeolojik ve hidrojeolojik özellikleri ile yeraltısularının hidrojeokimyasal fasiyes özellikleri incelenmiştir. Çalışma alanındaki jeolojik birimler otokton ve allokton olmak üzere iki grup halinde incelenmiş ve her bir litolojik birim hidrojeolojik özellikleri ve akifer olabilme potansiyelleri bakımından gözenekli akifer, karstik akifer, yarı geçirimli ve geçirimsiz birimler olarak ayırtlanmıştır. Çalışma kapsamında, Mayıs (2019) döneminde çalışma alanındaki sondaj kuyularında 27 adet yeraltısuyu örneği alınmış ve suların fiziko-kimyasal özellikleri belirlenmiştir. Suların analiz sonuçları ve Coğrafi Bilgi Sistemlerinden (CBS) yararlanılarak iyon dağılım haritaları hazırlanmıştır. Ayrıca farklı hidrojeokimyasal değerlendirme diyagramları kullanılarak suların kimyasal süreçleri değerlendirilmiştir. Piper diyagramına göre Ca-Mg-HCO3 ve Ca-HCO3 baskın su tipleri olarak belirlenmiştir. Gibbs diyagramlarına göre, yeraltısularının tamamı kayaç baskın bölgede bulunmakta olup belirlenen başlıca hidrojeokimyasal süreçler ise karbonat ayrışması ve silikat ayrışmasıdır. Ayrıca, iyon değişimi akifer ortamda gelişen muhtemel süreçlerden birisidir. Elde edilen sonuçlara göre, çalışma alanındaki yeraltısuyu kimyası başlıca kayaç-su etkileşiminin kontrolünde gelişmektedir. Ancak, bölgedeki tarımsal faaliyetler de su kimyası üzerinde etkindir.

“…All the sample representatives of recharge and discharge areas have Na/Cl ratio less than 1 reflecting the prevalence of ion-exchange process acting in the Akure area (Elango et al 2003). All the groundwater samples from recharge areas have positive Chloro Alkaline Indices values which suggest the presence of direct ion exchange of Na and K from water with magnesium and calcium in the aquifer material/rocks underlying Akure area (Bozdag 2016). Three groundwater samples in the discharge areas have negative CAI values suggesting the presence of ion (cation-anion) exchange, and this exchange is indirect (Schoeller 1967; Marghade 2015).…”

The inhabitants of Akure Metropolis, southwestern Nigeria, depend solely on groundwater for their domestic, industrial and irrigation purposes. There is a need to delineate recharge and discharge areas for assessment and management of groundwater in these areas. One hundred and ninety (190) dug wells were selected for this assessment. Elevation and water table data aided accurate delineation of recharge, discharge and groundwater divide areas. Thirty-six wells representative of recharge and discharge areas were subjected to pollution assessment [DRASTIC, water quality index (WQI) and runoff potential]. The results revealed that the recharge areas have higher pollution potential and runoff amount than the discharge areas. This implied that groundwater sourced from recharge areas was more pollution prone than that sourced from discharge areas. WQI results revealed that the waters from recharge and discharge areas fall within excellent, good, poor, and unsuitable quality categories. Hydrogeochemical results revealed that concentrations of cations and anions are in order of Ca 2+ > Mg 2+ > K + > Na + and HCO 3 − > Cl − > SO 4 2− with a predominant Ca-HCO 3 facies typifying water from a basement complex environment. Gibbs plot and chloro-alkaline index affirmed the rock dominance and existence of imprints of ion-exchange processes influencing the groundwater quality. Intense weathering activities aided with long resident time spent by the water in the voids of the aquifer media are characteristic in this terrain. Recharge of precipitating water through infiltration into the weathered basement aquifers is a pointer to the greater yield of water in the wells. The possibility that precipitation-weathering process has led to the increase in concentrations of all ionic species and possible pollution of the groundwaters from the recharge and discharge areas cannot be ruled out at all.

“…In addition, the potentiality of adverse effects of water components varies with crop variety and soil condition. Worldwide there were many water quality indices (IWQI) models developed to evaluate the irrigation water quality for better crop growths and productions (Wilcox 1948;Doneen 1964;Ayers 1977;Ayers & Westcot 1985;CCME 2006;Simsek & Gunduz 2007;Meireles et al 2010;Bauder et al 2011;Bozdağ2016;Arslan 2017;Hussain et al 2018;Zaman et al 2018;Singh et al 2020). But those models have some limitations and are not able to accurately evaluate the irrigation water quality.…”

There are many irrigation water quality indices used to assess water suitability, despite some of their limitations. Hence, it is imperative to develop a water quality index to evaluate the irrigation water more accurately. This study has aimed to emerge an Integrated Irrigation Water Quality Index (IIWQIndex) using the sub-index and aggregated equations. This proposed index model was considered to be improved and updated in four aspects: the verified desirable and permissible value of parameters, maximum hazard class, used a modified rating system of parameters, and diversified parameters were considered. The proposed IIWQIndex model classified irrigation water into five categories, i.e., rejection, poor, moderate, good, and excellent. This model assessed two types of water to justify the model by categorizing the irrigation waters. The calculated results showed that the index values were 75.77 and 36.51, and the water category fell under ‘good’ and ‘rejected’ for the calcite (Ca-HCO3) and sodic (Na-Cl) water, respectively. Besides, this index model satisfactorily evaluated different types of water datasets of eight geographic locations in the world. The study illustrated that the IIWQIndex evaluated values and water categories were rational and exhaustive to predict the suitability of irrigation water.
