Introduction
• Importance of water quality
• Seasonal effects on lakes
• Need for WQI assessment
About Manasbal Lake
• Location: J&K
• Ecological and tourism value
• Why this lake was chosen
Project Objectives
• • Assess seasonal water quality variations
• • Calculate Water Quality Index
• • Compare pre- and post-winter results
Methodology Overview
• • Sample Collection
• • Lab Testing
• • Data Analysis
• • WQI Calculation
Sampling Strategy
• • 11 sampling sites
• • Pre-Winter and Post-Winter visits
• • Instruments used: DO bottles, pH meter etc.
Parameters Analyzed
• • pH
• • DO
• • BOD
• • Nitrate
• • Phosphate
• • Turbidity
Water Quality Index (WQI)
• • What is WQI?
• • Formula used
• • Weightage and rating system
WQI Classification
• 0-25: Excellent
• 26-50: Good
• 51-75: Poor
• 76-100: Very Poor
• >100: Unsuitable
Lab Testing Process
• Detailed process for each parameter:
• • DO (Winkler’s)
• • BOD (5-day incubation)
• • Nitrate & Phosphate (Colorimetric)
Pre-Winter Data Collection
• Photos & notes from pre-winter sampling
Post-Winter Data Collection
• Photos & notes from post-winter sampling
Comparison Table
• Pre vs Post-Winter Average values
• (Table of parameters)
Graph: pH Variation
• Graph showing site-wise pH variation across
seasons
Graph: DO Variation
• Graph showing site-wise DO variation
Graph: BOD Variation
• Graph showing BOD variation
Graph: Nitrate Variation
• Graph showing nitrate changes
Graph: Phosphate Variation
• Graph showing phosphate levels
Graph: Turbidity Variation
• Turbidity across sites and seasons
WQI Results (Pre-Winter)
• Table of WQI site-wise before winter
WQI Results (Post-Winter)
• Table of WQI site-wise after winter
WQI Graph Comparison
• Graph comparing WQI pre vs post
Top Polluted Sites
• Sites with max WQI drop
Discussion
• • Seasonal impacts
• • Sources of pollution
• • Trends observed
Challenges Faced
• • Weather
• • Access to sites
• • Lab constraints
Suggestions
• • Need for regular monitoring
• • Use of WQI in decision making
Future Scope
• • Long-term monitoring
• • Involvement of local communities
Conclusion
• • Summary of findings
• • Post-winter degradation observed
References
• Books, BIS standards, research papers
