Creating great data stories can be tough, especially for new researchers, but it is doable! You just need to learn how to tell a clear story with your data and learn how to create a good visual narrative and use visuals with purpose, and where to use simple data to create a visual to tell your story. This is a robust guide to help you think through every part of your study, including knowledge to develop your charts and colors, software recommendations, and storytelling methods, so that your research is not only informative but engaging to your audience.
Finding the Right Research Question
Writing a strong research question is one of the most critical steps of conducting an impactful water quality project. It's easy to get caught up in testing and collecting samples - but, if you aren't using the data to answer a specific and personal question, even the best data may seem irrelevant. A research question not only transforms a typical test into an exploration, but it also gives the research a story, purpose, and significance. Just like a good plot will haunt readers after finishing a good book, a good research question will haunt the reader after sampling and testing. Here is how to craft a question that will be important to you and to your community.
Common Types of Water Quality Projects
Water quality projects can be created to understand a variety of angles of the environment, chemistry, biology, or public health. The first step to keep your motivation over a number of weeks or months of research is to select a type of project that really interests you.
Chemical Parameter Testing:This is the most typical project, where students analyze the characteristics of substances such as pH, nitrate, phosphate, dissolved oxygen, or heavy metals such as lead or arsenic. These characteristics are useful in answering questions about pollutants, safety, and potability information.
Location-Based Comparisons: These projects investigate water quality differences between multiple sites. Students might test upstream and downstream of a factory, compare urban vs. rural wells, or even analyze how water in a bottle compares to tap water.
Temporal or Seasonal Studies: For projects that take place over several weeks, students can document how water quality changes over time. A temporal study can be useful to show how pollution levels are impacted by weather, farming seasons or festival periods.
Study of Natural or treated water: The purpose of this study is to compare sources of raw water such as pond or stream water to bathtub sources of treated water such as municipal tap water or filtered water. These studies are generally correlated to health and safety.
Community-Based Surveys with Testing: This type combines field testing with social data. For example, you might survey local residents about water access while also testing the water quality in their homes.
Each of these paths is valid, rich in learning, and scientifically rewarding. Choosing one depends largely on your local context and your own curiosity.
What Makes a Question Worth Exploring?
You don’t need a Nobel Prize-worthy problem. But your question does need to be specific, measurable, relevant, and achievable with your available tools and timeline. Great water quality questions share a few key traits:
They connect to the real world. If your question is about a river, school tap water, or borewell in your neighborhood, people care about your results, not just your science teacher.
They’re clear and focused. Avoid overly broad or vague questions like “Is my river polluted?” Instead, ask “How does nitrate concentration vary in this river during the monsoon season?”
They are testable. Your question should point to something you can physically measure using simple instruments, chemical strips, digital meters, sample bottles, or surveys.
They invite discovery. The best questions inspire a thirst for the answer, and even if the answers are simple, they help you learn the process of observation, interpretation, and meaning from the world around you.
When you’re formulating your question, ask yourself: Can I collect enough data to answer this clearly? Do I have the tools and time? Is this something people should know more about? If you can say yes to those, you’re on the right path.
Making It Personal and Local
The most memorable water quality projects are the ones that stem from your own life—your own questions, worries, or observations. Maybe you once noticed a strange color in a neighborhood stream. Maybe your grandparents boil water even when it comes from a municipal tap. Maybe there’s a fish kill after Holi or Diwali every year. That’s not just coincidence, that’s a research opportunity.
Here’s how to start making it personal:
Walk around your area. Look for signs of pollution, pipe leaks, algae blooms, dry ponds, or blocked drains. Take notes or photos.
Talk to people. Ask local residents, teachers, or farmers if they’ve noticed changes in their water quality, or if they boil/filter their water and why.
Think seasonally. What happens to water after the monsoon? After harvest season? Around festivals?
Explore cultural or historical context. In many places, rivers have religious or historical value. Projects that examine water quality in these “sacred” locations often uncover fascinating tensions between belief and pollution.
Personal connection is not merely an emotional motivator; it also lends authenticity and richness to your research. When judges or readers see your work is grounded in a lived experience, they're invested. More importantly, so will you.
Understanding Water Quality: What You’re Really Measuring
What do you think about when you hear the phrase "clean water"? Do you imagine a clear stream running high in the mountains? A bottle of mineral water purchased from the local store? A clean glass of water that has no odor? It's not a question of the look or taste of water; water quality is a scientific amalgam of chemical, physical and biological properties. By understanding these concepts, we can determine whether water is "clean", "polluted", "potable" and/or "unsafe".
However, in order to see what we can measure; and happen upon our "why" we must first understand what the water data is telling us with respect to what we are measuring. Before you can start your analysis, interpretation, or conclusions in your study, you first need to clarify what it is your water data is telling you. Each parameter, such as pH, nitrates, turbidites, etc., can be a pathway into a larger story. This section describes the most commonly analyzed parameters in high school research involving water quality, how they’re being measured, and what they can really say.
Core Water Quality Parameters
Typically, high school water testing kits or field investigations will contain five to eight standard indicators. The parameters are accessible and relevant, they can be measured with strips, digital meters or inexpensive reagents, and have real-world health and environmental implications.
pH: Typically, high school water testing or field work include five to eight standardized indicators. They are user-friendly and relatable; they can be performed using simple strips, inexpensive reagents, or even a digital meter, and ramifications are largely attached to health and the environment.
Turbidity: Refers to the murkiness or clarity of our water and is often due to suspended particulates such as: silt, algae, or organic material. While high turbidity does not always guarantee bad water, it does indicate there is something suspended in the water that is causing the turbidity or is preventing sunlight from penetrating in order to support aquatic ecosystems.
Dissolved Oxygen (DO): DO is essential for life, especially fish and other aquatic organisms. Water, with a low level of DO (look at the chart below, but under 3 mg/l is definitely not livable), is not suitable for life. DO levels can change during the day and during different weeks, depending on temperature or algae blooms, which makes it a variable indicator, yet an interesting indicator of water health.
Nitrates and phosphates: the sources of these substances are usually fertilizers, sewage, or waste. Elevated amounts can contribute to eutrophication, algae blooms, decreased oxygen, and unsafe drinking water (though certain levels for infants are necessary).
Biological oxygen demand (BOD): BOD is the amount of oxygen used by bacteria in consuming organic matter in the water. The more organic waste, the more food source for bacteria, and thus as bacteria reproduce BOD will increase meaning that the water is more polluted.
What Each Parameter Tells You
Understanding what to test is only half the battle. The real value comes in interpreting what your results mean in context. Here’s how these parameters help build a narrative in your project:
High pH or low pH? That might mean chemical waste, metal pipes leaching minerals, or natural limestone buffering.
Cloudy water? Could be sediment from soil erosion, algae from too much fertilizer, or even detergent runoff.
Low dissolved oxygen? Are there lots of decomposing plants? Is the water too warm? Has runoff brought organic material that bacteria are feeding on?
High nitrate levels? Is there agriculture nearby? Has it just rained—flushing fertilizers into your source? Could leaking septic systems be involved?
Spiking TDS? Is it due to natural mineral content—or are industrial effluents adding salts, metals, or chemicals?
Warm water temperatures? Could this stream be running next to a power plant? Are there no trees providing shade? Is climate change already altering its profile?
The best projects don’t just present numbers—they tell stories. And every parameter gives you a different character in that story. By connecting what you see to why it might be happening, you’re doing the work of a real scientist.
Choosing the Right Tests for Your Project
Let’s be realistic: you probably can’t test every parameter. And that’s okay—you don’t need to. In fact, smart science means choosing the right indicators for your specific question. Here’s how to decide what to test:
Match to your research question. If you’re studying fertilizer runoff, you’ll want to test nitrates and phosphates. If you’re studying fish health, then dissolved oxygen and temperature are key.
Match to your tools. If you only have stripes, test pH, nitrate, or chlorine. If you have a digital TDS meter, use it. Don’t overextend—accurate testing is better than pretending to test everything.
Match to your timeline. Some parameters (like BOD) require 5-day tests. Others (like pH) are instant. Choose based on how long you have and how often you can sample.
Match to your location. Are you testing rainwater? Surface water? Borewell? Treated tap? Each source comes with different likely issues—for example, heavy metals in groundwater, or high turbidity in surface water.
Also, remember, even one parameter, tested well over time or across many sites, can lead to a strong project. Quality matters more than quantity.
