Have you ever thought about the quality of water you drink? If you haven’t, well, you should, and if you have, then you join many others who share this concern. PFAS (per- and polyfluoroalkyl substances), lead, and old pipes are pressing issues in the U.S., prompting people to question even a single gulp. But getting assurance about your water’s quality is easier than you think, and guess what, you don’t need to buy anything to do that.
In this blog, we’ll show you how to test your water quality at home using simple tools you already have. No jargon. No geek device. Simple, practical solutions. So, let’s begin.
Why It is Important
A USGS study discovered that up to 27% of Americans may be at risk due to the presence of PFAS in the environment; the figure stands at nearly 95 million.
According to the EPA, in 2022, 27% of the public water systems did not follow public drinking water standards, and nearly 20% did not report correctly.
These figures confirm that it would be prudent to be aware of and monitor what is entering your system.
How to Test Your Water Quality at Home: Simple Techniques
Here are some easy and surprisingly effective techniques that can help you check your water quality.
See, Sniff, and Taste Test
Place a glass of tap water under a light. Now look for cloudiness, particles, or unusual colors. Then sniff. If you notice a rotten egg aroma, it is usually caused by hydrogen sulfide or bacterial growth. And taste? An acrid or metallic taste indicates something is not right.
Hard Water Residue Test
Fill a spoon or ladle with tap water and leave it there for a day or two. When you find white, chalky deposits, high calcium or magnesium levels are likely present in the water, which is common in hard water.
Under a Glass Magnifier
Fill a glass or bowl with water, run a bright ray of light through it, and observe the results through a magnifying glass. Cloudiness, foam, or floating strands may indicate contamination, even when the water appears clear at first glance.
Boil Test for Dissolved Solids
Boil a cup of water till the water has evaporated. Touch the pan on the bottom. Any chalky, sticky, or gritty deposits are a sign of dissolved minerals or solids, which is another red flag.
DIY Red Cabbage pH Test
Are you curious to know whether your water is overly acidic or alkaline? Boil a red cabbage until the water turns purple. Drop a bit of that into your tap water, the change of color will provide you with a rough estimate of the pH levels:
- Pink/red = acidic.
- Purple = neutral.
- Blue/green = alkaline.
A Real-life example: PFAS Scare in New York
Recently, The New York Post conducted a test of NYC tap water using an at-home test. PFBA, a PFAS chemical, was slightly above the Environmental Working Group standard, but the rest of the traditional contaminants were within American safety levels. Nevertheless, simple actions, such as running cold water for 30 seconds, were recommended to eliminate the risk of lead exposure.
It is also a good reminder that just because your simple tests are coming out satisfactorily, it does not mean that your water is not in violation of health standards, as indicated in water quality reports, which can usually be found by contacting your city or utility water company.
Why These Home Tests are Important
- Immediate awareness: Your senses and simple household tools can provide the first signs of potential problems.
- Free: No kit is needed. These methods are free.
- Provides instructions on what to do next: If something appears to be wrong, you will know whether to order a professional test or refer to your water quality report.
- Reddit comments: When taking into consideration serious problems like heavy metals, test strips, or self-developed techniques, they are inaccurate. The assurance will be best achieved through a certified lab.
