Testing water purity doesn’t always require expensive lab equipment. With outdoor plant boxes and a few natural indicators, you can create a simple, eco-friendly water test at home. Here’s how:

1. Select Sensitive Plants: Choose plants like watercress, duckweed, or ferns, which react visibly to contaminants. These species act as natural bioindicators.

2. Set Up Outdoor Plant Boxes: Fill the boxes with clean soil and plant your chosen species. Ensure they receive adequate sunlight and water.

3. Introduce Test Water: Replace regular watering with the water you want to test. Observe changes over 1-2 weeks. Healthy plants indicate clean water, while wilting or discoloration suggests impurities.

4. Compare Results: Use a control group with distilled water to compare plant health. Significant differences highlight potential contaminants.

5. Document Findings: Track plant growth, leaf color, and root health to assess water quality trends.

This DIY method is cost-effective and sustainable, making it ideal for gardeners, eco-enthusiasts, or anyone curious about their water source. For accuracy, combine it with traditional testing for comprehensive results.

By leveraging nature’s indicators, you can monitor water purity while reducing reliance on synthetic tools. Try it today and contribute to greener living!
