Modelling groundwater quality index based on sensitivity analysis for wet and dry seasons in Obio/Akpor local government area, Rivers state, Nigeria

Pollution control and removal of pollutants from groundwater are a challenging and expensive task. The aims of this paper are to determine the aquifer vulnerability of Sefid-Dasht, in Chaharmahal and Bakhtiari province, Iran, using the DRASTIC model. In addition, the groundwater quality index (GQI) technique was applied to assess the groundwater quality and study the spatial variability of major ion concentrations using a geographic information system (GIS). The vulnerability index ranged from 65 to 132, classified into two classes: low and moderate vulnerability. In the southern part of the aquifer, the vulnerability was moderate. Furthermore, the results indicate that the magnitude of the GQI index varies from 92% to 95%. This means the water has a suitable quality. However, from the north to the south and southwest of the aquifer, the water quality has been deteriorating, and the highest concentration of major ions was found in the southwest of the Sefid-Dasht aquifer. A comparison of the vulnerability maps with the GQI index map indicated a poor relation between them. In the DRASTIC method, movement of groundwater is not considered and may be the reason for such inconsistency. However, the movement of groundwater can transport contaminants.

ABSTRACTSoil transmitted helminthes (STHs) are common public health concern among children in Sub saharan Africa. A study to determine the prevalence and intensity of these parasites among pupils of two primary schools in Nkpor and Mgbodohia communities, Obio/Akpor Local Government Area, Rivers State, Nigeria was conducted. The formo-ether concentration technique was used to concentrate and separate the eggs and cysts from the faeces. Out of 107 pupils (56males and 51 females) investigated, 81 (75.7 %) were positive for at least one gastrointestinal helminth. The parasites identified included Ascaris lumbricoide(58.0%), Hookworms(28.4%), Trichirus trichiura(13.6%) and A.lumbricoide + T. trichiura (6.3%). Ascaris lumbricoide was significantly (P<0.05) higher in prevalence than other parasites. Although more females (54.3%) were infected than males (45.7%), there was no significance(P>0.05) difference in the prevalence in relation to sex. Of the 44 males infected, 24(54.5%), 5 (11.4%), 13(29.5%) and 2(4.5%) haboured A. lumbricoide, T. trichiura, Hookworms and mixed infection (A. lumbricoide + T. trichiura) repectively. Out of the 37 females infected, 21 (56.8%), 3(8.1%), 10(27.0%) and 3(8.1%) haboured A. lumbricoide, T. trichiura, Hookworms and mixed infection (A. lumbricoide + T. trichiura) repectively. There was no significance difference in the prevalence of A. lumbricoide and Hookworms between males (54.5%) and females (56.8%). There was significant difference in prevalence among two major age groups (5-10years-45% and 11-15years-41.9%). Children within the age group of 16-20years had the least infection (9.9%). The intensities of A.lumbricoide, T.trichiura and hookworm were 246.5, 107.5 and 187 Epg respectively. The intensity of A. lumbricoide was significantly difference than other parasites identified.Soil transmited helminthes remain a public health concern among children in the study area. Provision of portable water, toilet facilities, good education on the epidemiology of STHs and regular de-worming will enhance control measures.

Entropy Weight Method

Groundwater in Phu My town is exploited essentially in Pleistocene aquifer and, used for many purposes like irrigation, domestic, production and animal husbandry. In this study, Groundwater Quality Index (EWQI) is calculated with Entropy weight method to determine the suitability of groundwater quality in study area. This method demonstrates the objectivity of each parameter calculated based on the degree of variability of each value and depends on the sample data source. The groundwater samples were collected from 17 wells in dry and wet seasons in 2017 with ten water quality parameters (pH, TDS, TH, Cl-, F-, NH4+-N, NO3--N, SO42-, Pb và Fe2+) were selected for analysising. The analysis results indicate groundwater quality is divided into 4 categories in this study area. In particular, over 70% of wells are "very good" water quality in both dry and wet seasons. Only 6% of wells are " water unsuitable for drinking purpose" of the total number of mornitoring wells in the study area.

Structured Questionnaire

The purpose of this study was to survey the technologies used in cassava processing in Ikwerre Local Government Area of Rivers State. Specifically, the study was proposed to determine the technologies used in harvesting, peeling, grinding, extracting water, sifting and frying crushed cassava tubers into Garri. A structured questionnaire titled “Survey of technologies used in cassava processing in Ikwerre Local Government Area of Rivers State (STUCP)”.was administered to one hundred-fifty farmers in ten villages in Ikwerre Local Government Area of Rivers State, Nigeria. Data was analyzed with the use of pictorial view of the technology used in cassava processing and Statistical package for social science was used in determining the frequency, percentage and mean. The findings revealed that more need to be done in terms of the technology used in harvesting, peeling, grinding, extracting water, sifting and frying crushed cassava tubers into Garri. One of the recommendations was that technology used in cassava processing should be improved in order to boost garri production in Rivers State.
