Bacteriological Analysis Of Water Tanks

Bacteriological Analysis Of Water Tanks

Abstract

An investigative study was carried out to determine the bacteriological rates of borehole water samples in halls of hearthstone in the University of Benin, Ugbowo Benin City. A aggregate of five water samples were collected from the the colorful halls of hearthstone in the academy. Bacteriological analysis was carried out using standard styles. The total bacterial count was determined by pour plate fashion and total coliform determined. Eight rubrics of bacteria which include Klebsiellaspp., Salmonellaspp. and Alcaligenesspp. were insulated from the water samples. Total bacterial count in water samples ranged from 0 to 32 x 102cfu/ ml. The total coliform count of the borehole waters anatomized ranged from 0 to 39 MPN indicator of coliform/ 50 ml. It was concluded that not all tank waters are safe for consumption and proper measures should be taken in cleaning and treating our water tanks regularly.

Chapter One

Preface

Water is necessary and intricately connected to life, without which there’s no life. This is the reason for which water must be given the necessary attention at all times. Good drinking water isn’t a luxury; it’s one of the most essential amenities of life itself. The force of safe drinking water to all has thus engaged the attention of numerous individualities, groups, governmental associations and private associations.( Adetunde etal. 2010).

Drinking water free of pathogenic organisms is abecedarian to breaking one of the top transmission routes of contagious complaint. This fact has stimulated worldwide investment in the construction of water systems that are designed to meet strict water quality norms.( Trevett, 2004).

Waterborne pathogens, including a variety of viral, bacterial, algal and protozoan agents, account for important of the estimated 4 billion cases and2.5 million deaths from aboriginal diarrheal complaint each time.( Kosek etal. 2003).

Increase in mortal population has wielded an enormous pressure on the provision of safe drinking water, especially in developing countries( Umeh etal. 2005). Unsafe water is a global public health trouble, placing persons at threat for a host of diarrheal and other complaint as well as chemical intoxication( Hughes etal. 2005). Unsanitary water particularly has ruinous goods on youthful children in developing world. Each time, further than 2 million persons, substantially children lower than 5 times of age, bones of diarrheal complaint( Kosek etal. 2003; Parashar etal. 2003).

Nearly 90 of diarrheal-affiliated deaths have been attributed to unsafe or shy- water inventories and sanitation conditions affecting a large part of the world’s population( Hughes etal. 2005; WHO 2004). An estimated2.6 billion persons warrant access to acceptable sanitation( Okonko etal. 2008).

The University of Benin, Benin City, has 5 main halls of hearthstone( halls 1, 2, 3, 4 and 5). There are also colorful staff diggings in the academy Inferior Staff Quarter, elderly Staff Quarter, Dentistry Quarter and Doctor’s Quarter. These halls depend on borehole water stored in overhead tanks for their water force.

Aim Of The Study

This study is aimed at the bacteriological analysis of the water from these tanks.

Objects Of The Study

1. To attain the total bacterial count of the water samples.

2. To determine the coliform counts( utmost Probable Number) of the water samples.

3. To determine the species of bacteria present in the water.
