    INTRODUCTION

    Course Introduction:

    Water quality testing is an important part of environmental monitoring. When water quality is poor, it affects not only aquatic life but the surrounding ecosystem as well. In this course, we will learn about the determination method of some of the parameters that affect the quality of water in the environment. These properties can be physical, chemical, or biological factors. The physical properties of water quality include temperature and turbidity. Chemical characteristics involve parameters such as pH and dissolved oxygen. Water quality monitoring can help researchers predict and learn from natural processes in the environment and determine human impacts on an ecosystem. These measurement efforts can also assist in restoration projects or ensure environmental standards are being met.

    Guideline for the course:

    • All the registered students for this course have to enroll in Moodle.
    • Students will find all the course materials from Moodle.
    • All the students have to submit the soft copy of their "Assignment" in Moodle under the assignment section created here and for this, they will be graded here.
    • One discussion or feedback forum is created under each of the lecture Students have to give their feedback on these fora and marks will be given for their feedback
    • Any announcement regarding the class will be posted on Moodle. So they have to keep themselves always active on Moodle.
    • All the quizzes and presentations will be held on the face to face class.
    • The question pattern and the syllabus for the quizzes, midterm, and the final exam is given hereunder each of the section (quizzes, midterm, and final)

    • There are midterm and final exam instructions forum under these sections where students can discuss with each other about their midterm and final exam syllabus, any problem regarding the exam, etc.

      Learning Outcomes:

      After completing this course, students will be able to:

      • Learn proper sampling method of water for analysis
      • Define and explain different terms and classifications of water quality parameters
      • Analyze physical and chemical of water quality parameters
      • Learn requirement quality of freshwater

  • Water Sampling For Lab Analysis


    Objective of this Lecture

    The main objective of sampling is to collect a portion of material small enough in volume to be  transported conveniently and yet large enough for analytical purposes while still  accurately representing the material being sampled. 

    Lecture Outcomes

    After this lecture, students will be able -

    • To use reliable and useful source for sample collection
    • To determine the quality of nature in its natural state
    • To assess the effect of human activities on water quality and its sustainability
    • To keep under observations the sources and pathways of pollutants / contaminants


  • Determination of Biological Oxygen Demand (BOD) of Water


    Objective of this Lecture

    The objective of this experiment is to determine the biochemical oxygen demand (BOD) of given water sample. BOD may have various units, but most often it is expressed in mg of oxygen required per liter of water/wastewater (mg/l).
