1.2       Statement of Problem

This project work was done in other to give a detailed account of the geology and hydrogeology of Ukpor and environs in Nnewi south local government area, Anambra State.as well as giving an insight on the quality of water and drainage system of the study area listed above

1.3       Aims and Objectives

The aim of this project is to be able to add to the literature of the geology and hydrogeology of the study area and also by the end of the report I hope to be able give a concise detail of the geological formations in the area and the way they affect or control the hydrogeology of the area and to independently apply/use field mapping techniques (especially lithologic logging of the sedimentary terrains) to gather geologic information of the area.

• To gather and interpret the geologic data of the Study Area. This implies to present a detailed geologic description of the mapped area by evaluating its lithologies (through logging), sedimentary structures, drainage types..
• To determine the textural properties and composition of the study samples, especially through sieve analysis.
• To appreciate and present the economic and hydrogeology significances of some Earth materials in the area.
• To produce, update and interpret the topographic, accessibility, drainage, and geologic maps (of the Study Area).
• To write a good geological report from the information gathered from the field. general geology, and produce a geologic map of the area.

1.4       Scope of study

The research involved:

• Review of  literature on the geology and sedimentology of the region
• Study of the topographic and geologic maps of the area to acquire first-hand information about the area.
• Reconnaissance survey of the Ukpor and environs, followed by detailed field work to gather information pertaining to the geomorphology, stratigraphic succession, and textural aspects of the rocks, sedimentary structures and drainage of the area.
• Production of a geological map showing the distribution of the various rock units and
• Understanding the portability of existing subsurface water as well as the nature of natural flowing stream water of the environment
• Compilation of a thesis to be submitted to the department of Geology.

1.5       Limitations and Constraints

• Inability to see an outcrop with reasonable sedimentary structures and cross beds that will enable us to take the strike and dip of the bed for paleocurrent analysis.
• Inaccessibility of roads to reach some outcrops for examination.
• Unavailability of some laboratory equipment for analysis.

• Some of the areas studied have ‘tough’ bushes which made it difficult to access and assess some rock units.
• Unavailability of funds thereby hindering more studies such as geophysical surveys in other to get a clearer understanding of the subsurface and also reducing the amount of days spent in the feild
• Some measurements made during the detailed fieldwork study, especially in paleocurrent analysis, presented approximated values because of error due to parallax.

1.6       study Area (Location and Accessibility)

The study area lies between longitude 6⁰ 55^’ N and 7⁰ 00^’ N and latitude 5⁰ 55’ E and 6⁰ 00^’ E. It is located in the Ameki group of the Anambra basin, the study area covers Ukpor and environs all  located in Nnewi south local government area, Anambra State south eastern part of Nigeria

The study area is accessible through many roads (both major and minor roads), and footpaths. It can be accessed by Uga- Nnewi road highway, Ichida – Amichi road, Igboukwu- Ezinifite road. E.t.c. the bodies of water (streams and river) can be crossed by feet because they are not too deep, the highest depth being about 1m. Local bridges have also been constructed in some parts of the River ulasi in Ukpor area, to enhance accessibility in the area.

It is bordered by Ihiala local government to the north, Aguata Local Government Area in the south and Aniocha to the west and Nnewi north to the east.
