Why Bottled Water Purity Matters
With the average adult human body consisting of 50-65% water, the quality of the water we drink significantly impacts long term wellness. Public health studies link increased contaminant exposure from poor quality drinking water to:
- Developmental damage in children
- Higher risk of gastrointestinal cancer
- Liver and kidney disorders
- Hypertension and cardiovascular disease
- Thyroid dysfunction
- Increased tooth decay or enamel erosion
"Over a lifetime, people ingest an average of 13,000 to 15,000 quarts of water containing various levels of health-affecting contaminants." – Natural Resources Defense Council (NRDC)
Many emerging water contaminants lack safety standards or treatment solutions. And even regulated substances often have legal limits well above lowest observable adverse effect thresholds.
With one study discovering over 35% of tap water samples testing positive for contaminants against only 5% of bottled water samples, bottled options offer sanctuary for health conscious consumers.
Understandably, GLOBAL bottled water consumption expands over 7% annually. Convenience and portability drives this trend. But for in-the-know purists like us, having confidence in water safety and purity remains priority number one.
Now let‘s explore how to objectively measure quality and taste across leading bottled water brands…
Evaluating Bottled Water Purity
As water passes through the environment, it dissolves minerals, gases, and substances picking up hints of its unique origin story – refreshing or foul.
Sensory factors like taste, odor, and visual clarity influence perceived water quality. But chemistry offers quantifiable insights.
Key metrics include:
- Total Dissolved Solids (TDS): Concentration of dissolved mineral salts or organics in water
- pH: Acidity or alkalinity measure
- Dissolved Solids: Inorganic mineral ions including calcium, chloride, sulfate etc.
- Contaminants: Heavy metals, pesticides, bacteria and other health hazardous substances
Understanding optimal levels across these criteria helps identify the purest and best tasting bottled waters tailored to your palate.
I‘ll also teach you how to easily test bottled water quality at home so you can verify brand claims and check each new bottle. Let‘s get started!
Total Dissolved Solids (TDS)
This key indicator measures the total concentration of dissolved substances in water. TDS comprises inorganic minerals, salts, metals and charged organic particles blended into the liquid during its journey through the hydrologic cycle.
The TDS reading indicates overall water purity and quality. The lower the level, the purer and cleaner it rates. As TDS concentration increases, so do dissolved impurities.
The EPA Secondary Drinking Water standards considers TDS levels:
- 0-50 ppm as excellent
- 50-150 ppm as good
- 150-300 ppm as fair
- 300-500 ppm as poor
- 500+ ppm as unacceptable
What‘s considered "good" TDS levels in bottled water? Let‘s evaluate the top brands…
Nestle Pure Life: 32 ppm
Scoring the lowest TDS reading at 32 parts per million, Nestle Pure Life ranked highest for exceptional water purity and quality. With barely any detectable dissolved solids, it provides a clean tasting transparent canvas to enhance with fresh fruit essence or extracts.

Bottled from source high in the French Alps since 1826, Evian Spring Water is legendary for quality and taste. While its 298 ppm TDS sounds high compared to purer peers, devotees insist Evian‘s well-balanced blend of calcium, magnesium and electrolytes makes for memorandum drinking moments.
Dissolved Solids
Related to total dissolved solids, dissolved solids specifically represent inorganic salts and small amounts of organic matter present in water that are not suspended particles, colloids or ions.
Major dissolved solids include calcium, magnesium, potassium and sodium cations or anions such as bicarbonates, chlorides and sulfates. As dissolved solids increase, it elevates water salinity impacting taste.
Higher mineral content leads to harder water with bolder flavor, whereas lower dissolved solids result in softer, cleaner tasting refreshment. Let‘s explore how they differentiate popular bottled water options…

Testing for Water Contaminants
Elevated total dissolved solids or specific dissolved ions indicate mineralized water profiles. But to assess true water purity, we need to evaluate potential contaminants.
Common concerning water pollutants include:
Heavy Metals
Lead – toxic for cognitive development and organ health
Mercury – bioaccumulates causing brain damage
Cadmium – carcinogenic prompting kidney disease
Arsenic – poisonous ties to cardiovascular conditions
Disinfection Byproducts
Chlorine – respiratory and cell damage at high levels
Chloramine – skin irritation and blood disorders
Inorganic Compounds
Fluoride – beneficial in small doses but toxic accumulation
Nitrates – methemoglobinemia, bladder & thyroid cancers
Nitrites – blood issues in infants under 6 months
Pesticides, Chemicals & Pharmaceuticals
Industrial compounds, prescription drugs and pesticides mix into the municipal water cycle with uncertain human health consequences since safety data remains sparse.
Thankfully, bottled water regulations demand exceptionally stringent purity standards limiting these substances to negligible levels in finished products compared to tap water.
But contamination lawsuits still occur. And with rising environmental pollution, home testing provides extra insulation even when choosing respected bottled water brands.
You can easily run tests using inexpensive water quality test strips purchased online or sourced locally. Ideal for household use, these kits provide sample pads that change color depending on detected concentration levels of various chemicals, metals, and water characteristics.
Here are best practices when using test strips:
- Carefully follow all kit/manufacturer instructions
- Always pull fresh strips from sealed containers
- Clean containers thoroughly between tests
- Rinse strips gently with distilled/deionized water before testing samples
- Avoid touching pads directly
- Objectively match colors against reference chart
- Spot check bottles periodically
