Objective:

Course objectives:

This course will enable the students to -

Appraise students about the latest analytical methods for qualitative and quantitative estimation of various chemicals in water.
Develop skills for planning and monitoring programmes for pollution prevention and interpreting the results.
Appraise students with different statistical skills for computing results.

Course Outcomes:

Upon completion of the practical course, students will:

CO25: Accurately calculate measures of central tendency and dispersion and perform statistical tests such as t-test, correlation & regression, ANOVA, etc., using Microsoft Excel, or other relevant software.

CO26: Develop the skills to conduct a range of physicochemical water quality analyses and the ability to interpret the observed results

CO27: Analyze data collected using respiratory dust and Handy samplers, interpreting the levels of respirable dust in ambient air and both respirable and suspended particulate matter indoors

CO28: Create a green file on current environmental issues, and accurately document experimental procedures and results in the practical file, ensuring comprehensive and precise records of laboratory activities & understanding of contemporary environmental challenges

CO29: Contribute effectively in course-specific interaction

STATISTICAL ANALYSIS

Classification and tabulation of data in Excel/any other software
Create and interpret graphical displays of data, such as histograms, box plots, and scatter plots.
Calculation of the following (Manual and using SPSS/Microsoft Excel/any other software)
- Measures of Central Tendency (Mean, Mode, Median)
- Measures of Dispersion (Standard deviation)
- Correlation (Karl Pearson & Spearman’s Rank Correlation
- Regression
- Chi-square test
- T-test (Paired and Unpaired)
- F-test
- Analysis of variance ANOVA

Note: A Non-Scientific Calculator is allowed in the CA and Semester End Examination

WATER ANALYSIS

Quantitative Estimation of the following parameters in the given water/wastewater samples:

Acidity
