This report is documentation on personal work experience industrial Training Attachment at the ministry of science and Technology, as part of the 2017/ 2018 students work experience scheme (SIWES) which commenced in August 2018 and lasted till October 2018. The chief objectives of this Training were to provide avenues for students in institutions of higher learning so as to acquire skills and experience in the course of study.

This report explains in details, the aims and objective of SIWES, the brief history of the ministry of science and technology, water and its standards, the challenges encountered, and the practical experience obtained during the training in microbiological analysis which is the determination of the presence of E-coli in water and other pathological microorganisms. It involves culturing of microbes, treatment of water and media. The procedure for microbiological analysis and its chemical significance are also contained in this report. Elemental analysis was done by spectroscopy to determine the concentration of metals (including heavy metals) in a sample of interest. Chloride concentration in water was done by Mohrs Argentometric titration; total suspended solids and total hydrocarbon content were carried out on water samples. Procedures for each of this analysis, and their chemical significance. Basic stages in water treatment, conclusion, and recommendation are also contained in this report.  



The Background of the Study:

    The student industrial work experience scheme (SIWES) is a skill training programme designed to expose and prepare Nigerian students in tertiary institutions such as Universities Polytechnics colleges of technology, colleges of agriculture, and colleges of education to the realities of the work environment in Nigeria, especially the world in general, in their chosen profession so as to achieve the much need technological advancement for the nation.

    The scheme is effective which gives students studying occupational-related courses the experience that will supplement their theoretical learning. As such industrial training is very important in their chosen profession.

    The scheme also affords the opportunity of familiarizing and exposing students to the needed experience in handling equipment and machinery that are usually not available in institutions.

    The first major role is that it will provide an opportunity for the students to put in practice the theoretical knowledge acquired in the classroom.

    Secondly, it exposes students to work methods and techniques in handling equipment and machinery in the industrials sector. In addition, it provides students the opportunity to prepare for employment after graduation. This technical report gives a summary of my experience during my three months industrial attachment to Akwa Ibom State Ministry of science and technology.


    This student industrial work experience scheme known by the acronym SIWES was established in 1971 by decree 47 of the Federal Government of Nigeria with the aim of practically developing students in tertiary institutions of learning. This was to bring skilled manpower to the Nigerian economy. This was followed by the subsequent establishment of industrial training fund (ITF) in 197A to oversee the affairs of students in their respective department of learning and to monitor the progress of student in any industrial establishment other bodies under SIWES include:

(i)    (NUC) National University Commission.

(ii)    (NBTE) National Board for technical education.

(iii)    (NCCE) National council for college of education.


SIWES provides avenue for students to acquire industrial skills and experience in their approved course of study. SIWES prepare student for their industrial work situation which are likely to meet after graduation.


Some specific objectives of SIWES are stated below:

⦁    To bridge the identified gap and practices of engineering and technology in tertiary institution.

⦁     Provides avenue for students in institution of higher to acquire skills and experience in their course.

⦁    Prepare students for post graduation work situation.

⦁    Expose student to work  methods and techniques in handling equipments and machinery that may not be available in educational institution.

⦁    It provides opportunity for students to apply their  thereby knowledge in real work situation thereby bridging the gap between theory and practical.

⦁    Ease the transition from school to the work of work and enhance student’s contacts for later job.

⦁    Ernest placement and strength employees involvement in the educational process of preparing students for employment in industries.


    Ministry of science and technology was born out the former Bureau of Science and Technology which was created in July 2000. The Bureau of Science and Technology was created due to the former state Governor, His Excellency Arc. (Obong) Victor Attah’s commitment towords the development of science and technology in the state. The Bureau of science and technology was headed by a special adviser.

    In August 2003, the Bureau of Science and Technology was upgraded to a full-fledged ministry, headed by the Honourable Commissioner for science and technology. The ministry has seven (7) Directorates which are; science technology and science promotion, engineering, administration, planning, research and statistics (P.R.S), and ICT.

    The ministry of science and technology research and development laboratory was created as part of the ministry in 2013. It was established so that the result of scientific research conducted may be translated into industrial enterprise to produce goods and services that are acceptable and used within and outside the Country, and to make science and technology the ministry of the state’s economy through research and development.

    Currently, the laboratory is headed by the Director of science, Mr. Gerald Inoh and managed by Mr. Etim Ekpo. The laboratory is accredited by the Department  of Petroleum Resources (DPR) and Federal Ministry of Environment.
