**INTRODUCTION**
 * CHAPTER I**

Since Iligan City is surrounded by seas on one side and mountains on the other, going to the beach has been one of the favorite pastimes of Iliganons, this also means one of the major sources of income is fishing. Also because it is surrounded by seas, it resulted to businessmen constructing major industries in Iligan City’s bays. The city became prosperous because of the many industries found on the city’s local bays. The industries found in Iligan City are: Global Steel Philippines located in Brgy. Suarez, Mabuhay Vinyl Corporation located in Brgy. Maria Cristina. Also there is a factory located in Brgy. Dalipuga known as Pilmico Foods Corporation. Furthermore, some known industries in Iligan City are located in Brgy. Kiwalan which are: Petronas Energy Philippines, Inc., Pilmico Iligan Feedmill, Iligan Cement Corporation, Mindanao Portland Cement Corporation, Granexport Manufacturing Corporation and Holcim Philippines, Inc. There is another work place of the city as well, the Iligan Port Area which is a major connection of the city to other cities. The difference between the quality of seawater on seashores along communities and the water quality on seashores along industries are quite unknown to the people living in this city. One group of people, for example, a family can just go to random beaches they may think of because of its affordability and/or proximity but they may not be aware of the fact that the beach they are enjoying can cause irritation to their skin. The quality of seawater determines whether it is safe for the people to bath and if it contains harmful bacteria that could cause skin diseases.
 * A. Background of the Study**

Which beach among the 2 selected beaches has the best quality for bathing? · Is there a significant difference in seawater salinity of samples collected along seashores nearby industries and along nearby residential areas? · Is there a significant difference in seawater turbidity of samples collected along seashores nearby industries and along nearby residential areas? · Is there a significant difference in seawater pH level of samples collected along seashores nearby industries and along nearby residential areas? · Is there a significant difference in the temperature of seawater samples collected along nearby industries and along nearby residential areas?
 * B. Statement of the Problem**
 * Main Problem**
 * Sub-Problem**

This study basically aims to determine the water quality for bathing between the two selected beaches located along Iligan City’s bays. In order for this study to be completed, objectives are stated below: · To identify the possible bacteria present in the seawater samples found from the selected beaches in Iligan City’s bays. · To compare the water quality for bathing of the selected beaches in Iligan City’s bays.
 * C. Objectives of the Study**

· Seawater along nearby residential areas has better quality for swimming than seawater along nearby industrial areas. · Seawater along nearby residential areas has better quality for swimming in terms of salinity than that of the seawater along nearby industries. · Seawater along nearby residential areas has better quality for swimming in terms of the turbidity of water than that of the seawater along nearby industries. · Seawater along nearby industries has higher temperature than that of the seawater along nearby residential areas.
 * D. Hypotheses of the Study**

This study is beneficial to all the people living in Iligan City and to those people living alongside shores so that they might enjoy the beaches that they frequently go to the fullest without the bother of irritants - that might constraint people’s daily activity - or floating garbage and that the natural resources of Iligan City like it’s marine aquaculture is protected from further damages.
 * E. Significance of the Study**

The sources of the seawater that would serve as samples would only come from the selected beaches namely: Reg’s Beach Resort and Canaway Beach located in Barangay Sta. Felomina Iligan City, and Purok 14 Canaway Iligan City, respectively. The seawater samples are analyzed in the laboratory of the Department of Biological Sciences, College of Science and Mathematics, MSU-Iligan Institute of Technology, Iligan City. This research mainly focused on the salinity, temperature, turbidity, bacteria present and pH level of the seawater. Furthermore, the turbidity is tested by a secchi disk and the researchers wouldn’t focus more on the specific bacterial content, bacterial count of the seawater.
 * F. Scope and Delimitations of the Study**


 * G. Definition of Terms**
 * Salinity** - the saltiness or dissolved salt content of a body of water. In this study, salinity is measured in terms of parts per thousand (ppt).
 * Turbidity** - the cloudiness or haziness of a fluid caused by individual particles (suspended solids) that is generally invisible to the naked eye.
 * pH level** -
 * Temperature** -
 * Secchi disk** -
 * Quality of water** -
