Water Quality Indicators
What does pH measure in water?
The acidity or alkalinity.
What tool was used to measure water quality in the experiment?
A digital water quality meter.
What does the team aim to protect by providing cleaner water?
Public health.
Which village served as the research site?
Babakan Madang.
Which three factors were found above ideal values?
pH, TDS, and Nitrate.
What is the ideal pH range for drinking water?
Between 6.5 and 8.5.
How were the water samples collected to ensure accuracy?
Samples were taken at three distinct points from each location and stored immediately.
What should always be obtained before involving individuals in data collection?
Informed consent.
What was the team’s proposed long-term solution?
A collaborative water filter and waste management system.
What does high nitrate in water usually indicate?
Pollution from fertilizers, human or animal waste.
Which factor measures the cloudiness of water due to suspended particles?
Turbidity (measured by TDS – Total Dissolved Solids).
What direction relative to the river’s flow were samples collected from?
Upstream, midstream, and downstream.
How did the team ensure transparency with the local community?
By openly communicating results and outcomes.
What kind of filter is the team aiming to develop?
An eco-friendly, low-cost, reusable filtration system.
What conclusion was made about the river’s ability to support aquatic life?
Unable to support fish
What does TDS stand for, and what does it measure?
Total Dissolved Solids; it measures dissolved substances like minerals and salts in water.
Name two parameters tested to assess water safety.
pH and Nitrate levels (also accepted: TDS, DO).
Why is it important to communicate long-term benefits of the project?
To build trust and demonstrate environmental and health value.
Name one public health benefit from the proposed solution.
Reduced risk of illness from contaminated water.
What might have caused the increase in pollutants along the river?
Domestic waste, fertilizers, and human activity.
Why is dissolved oxygen (DO) critical to aquatic ecosystems?
It is essential for the survival of aquatic organisms like fish.
Why is it important to test samples at different river locations?
To capture pollution variation across points and identify contamination sources.
Name a way the team minimized ethical risks during data collection.
Respecting autonomy, obtaining informed consent, and avoiding misinformation.
How does this project align with environmental education goals?
It raises awareness about pollution and clean water’s importance.
According to the findings, what type of water treatment is recommended?
Filtration and waste management
