The study area (Ikot Ekpene &#8211; Obot Akara Local \nGovernment Areas) continues to experience a swift increase in human population and associated \neconomic activities, leading to the generation of more solid wastes. This could result in \ngroundwater contamination, which can put the local pollution in severe danger. The fundamental \ngoal of this work is therefore to weigh up the groundwater standard through hydrogeochemical \ninvestigation of groundwater samples and the susceptibility potential of the economically exploited \naquifer units in the area. The results of the electrical geo-sounding data acquired at 28 locations in \nthe area reveal three to four lithological successions comprising fine\/coarse sands and gravels amid \npatches of thin clay interbeddings at several places. The primary aquifer in the area is the third \nlayer, which is between 10.5 and 101.5 m deep with resistivity values between 359.4 and 2,472.8 \n\u03a9m. The hydrogeochemical evaluation of groundwater samples in the area shows that the measured \nphysicochemical parameters are well within the World Health Organization\u2019s acceptable limits \nexcept for lead and nickel ions. These metals are shown to be the most significant parameters \naffecting the groundwater quality in the area. The groundwater quality and susceptibility potential \nmaps generated seem to correlate well and clearly demarcate the poor groundwater quality\/high \nsusceptibility potential zones. These maps are useful tools that could aid policymakers in successful \ngroundwater management in the area to meet the needs of the populace.<br><\/p>\n\n\n\n\n\n\n\n\n\n\n<strong>Groundwater potential and quality assessments of a coastal environment: a case study of the \nlocation of Federal University of Technology Ikot Abasi (FUTIA), Akwa Ibom State, Nigeria<\/strong>\n<p><em><strong>George, N.J and Thomas, J.E<\/strong><\/em><br><\/p>\n<p style=\"text-align: justify;\"><strong>Abstract<\/strong>: The economic, residential, agricultural, educational, and social relevance of groundwater to coastal\nresidents provoked the selection of FUTIA and its surroundings, located along the Okpobo River and \nAtlantic Ocean shorelines, for integrated geo-electrical and hydrochemical investigations.

The study area is fraught with surficial unconfined aquifers drilled to follow the depths of the \npreexisting productive but vulnerable aquifers near them. The untapped semi-confined to confined \naquifers for depths &gt; 30 m and less than 200 m were viewed to have less susceptibility to contaminations \ndue to the presence of overlying argillaceous units concealing them&#8230;<\/p>\n\n\nDEVELOPMENT AND EVALUATION OF A CONSTRUCTED PILOT- SCALE HORIZONTAL\nSUBSURFACE FLOW WETLAND TREATING PIGGERY WASTE WATER\n<p><strong>I.J. Udom , C.C. Mbajiorgu , E.O. Oboho<\/strong><br><\/p>\n<p style=\"text-align: justify;\"><strong>Abstract <\/strong>: Intensive piggeries are predominating livestock production and there is rising concern of nutrient pollution from the \nuse of floodplains and water bodies as convenient sinks for the disposal of untreated wastewater. Conventional \nsystems are not suitable solutions in preventing water pollution in developing countries due to their prohibitive cost \nand highly mechanized system with high energy and minimum inflow requirements which cannot be afforded by \nfarmers. Natural systems, such as constructed wetlands are less costly, and have low energy requirements. However, \nlack of information on their performance in the tropics is among the factors that hinder their adoption as alternative \nwastewater treatment system. Successful removal of nutrients in piggery wastewater by constructed wetlands has \nbeen reported in different climatic regions outside Nigeria and their optimal design, performance, effects of plants \nand climate change on performance and the prediction of these effects need verification. The objective of this study \nwas design, construct and test and model the performance of a horizontal subsurface flow wetland for treatment of \npiggery wastewater.<br><\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"pagelayer_contact_templates":[],"_pagelayer_content":"","footnotes":""},"class_list":["post-1807","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/aksu.edu.ng\/newsite\/wp-json\/wp\/v2\/pages\/1807","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aksu.edu.ng\/newsite\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/aksu.edu.ng\/newsite\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/aksu.edu.ng\/newsite\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/aksu.edu.ng\/newsite\/wp-json\/wp\/v2\/comments?post=1807"}],"version-history":[{"count":9,"href":"https:\/\/aksu.edu.ng\/newsite\/wp-json\/wp\/v2\/pages\/1807\/revisions"}],"predecessor-version":[{"id":1856,"href":"https:\/\/aksu.edu.ng\/newsite\/wp-json\/wp\/v2\/pages\/1807\/revisions\/1856"}],"wp:attachment":[{"href":"https:\/\/aksu.edu.ng\/newsite\/wp-json\/wp\/v2\/media?parent=1807"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
