There are several types of drinking water, each differing in source, treatment, and mineral content. Here’s a clear breakdown:
1. Tap Water
- Supplied by local municipalities
- Treated to meet safety standards
- Can vary in taste and quality depending on location

2. Purified Water
- Water that has been filtered or processed to remove impurities
- Includes methods like reverse osmosis (RO), distillation, deionization
- Often used for household drinking systems
3. Mineral Water
- Comes from natural underground reservoirs
- Contains naturally occurring minerals like calcium, magnesium, and potassium
- Bottled at the source
4. Spring Water
- Originates from a natural spring
- Flows to the surface naturally
- Typically filtered but not heavily processed
5. Distilled Water
- Purified through boiling and condensation
- Very low mineral content
- Often used for appliances or medical use; not ideal for everyday drinking due to lack of minerals
6. RO (Reverse Osmosis) Water
- Passed through a semi-permeable membrane to remove dissolved salts and impurities
- Very pure but often low in minerals
- Many households remineralize RO water
7. Alkaline Water
- Has higher pH than regular water
- Made by adding minerals or using an ionizer
- Marketed for health benefits (scientific evidence is limited)
8. Sparkling Water
- Carbonated water, either naturally carbonated (from springs) or artificially
- Includes soda water, club soda, and seltzer
9. Well Water
- Drawn from underground aquifers using private wells
- Safety depends on local geology and regular testing
10. Artesian Water
- Comes from confined aquifers under natural pressure
- Often marketed as premium water
11. Flavored or Infused Water
- Water with added natural flavors, fruits, or herbs
- Sometimes contains added sugars or sweeteners
🔍 Comparison of Water Types
1. Purified Water
- Source: Any (tap, underground)
- Treatment: Filtration + purification (e.g., RO, UV, carbon)
- Minerals: May be removed; sometimes added back
- Taste: Clean, neutral
- Pros: Very low contaminants; safe
- Cons: May lack natural minerals
2. Mineral Water
- Source: Natural springs or underground reservoirs
- Treatment: Minimal; bottled at source
- Minerals: High natural minerals (Ca, Mg, K)
- Taste: Slight mineral flavor
- Pros: Naturally rich in minerals; good for health
- Cons: More expensive; not always sustainable
3. RO (Reverse Osmosis) Water
- Source: Usually tap
- Treatment: Forced through semi-permeable membrane
- Minerals: Very low (most removed)
- Taste: Very smooth, light
- Pros: Removes heavy metals, chemicals, microbes
- Cons: Removes good minerals too; slight waste of water
4. Distilled Water
- Source: Any
- Treatment: Boiled → condensed
- Minerals: Zero
- Taste: Flat
- Pros: Purest form; toxin-free
- Cons: No minerals; not ideal for daily drinking
5. Tap Water
- Source: Municipal supply
- Treatment: Chlorination, filtration
- Minerals: Varies by region
- Taste: Depends on pipes & treatment
- Pros: Cheap, accessible
- Cons: Taste or quality can vary; may contain chlorine or micro-impurities
- Which One Is Best?
- Best for Health (natural minerals): → Mineral Water
- Best for Areas with Hard/Unsafe Water: → RO Water
- Best General & Safe Option: → Purified Water
- Best for Machines/Medical Use: → Distilled Water

Dr. Mohammed Abdul Azeem Siddiqui, MBBS, M.Tech (Biomedical Engineering – VIT, Vellore)
Registered Medical Practitioner – Reg. No. 39739
Physician • Clinical Engineer • Preventive Diagnostics Specialist
Dr. Mohammed Abdul Azeem Siddiqui is a physician–engineer with over 30 years of dedicated clinical and biomedical engineering experience, committed to transforming modern healthcare from late-stage disease treatment to early detection, preventive intelligence, and affordable medical care.
He holds an MBBS degree in Medicine and an M.Tech in Biomedical Engineering from VIT University, Vellore, equipping him with rare dual expertise in clinical medicine, laboratory diagnostics, and medical device engineering. This allows him to translate complex laboratory data into precise, actionable preventive strategies.
Clinical Mission
Dr. Siddiqui’s professional mission centers on three core pillars:
Early Disease Detection
Identifying hidden biomarker abnormalities that signal chronic disease years before symptoms appear — reducing complications, hospitalizations, and long-term disability.
Preventive Healthcare
Guiding individuals and families toward longer, healthier lives through structured screenings, lifestyle intervention frameworks, and predictive diagnostic interpretation.
Affordable Evidence-Based Treatment
Delivering cost-effective, scientifically validated care accessible to people from all socioeconomic backgrounds.
Clinical & Technical Expertise
Across three decades of continuous practice, Dr. Siddiqui has worked extensively with:
Advanced laboratory analyzers and automation platforms
• Cardiac, metabolic, renal, hepatic, endocrine, and inflammatory biomarker systems
• Preventive screening and early organ damage detection frameworks
• Clinical escalation pathways and diagnostic decision-support models
• Medical device validation, calibration, compliance, and patient safety standards
He is recognized for identifying subclinical biomarker shifts that predict cardiovascular disease, diabetes, fatty liver, kidney disease, autoimmune inflammation, neurodegeneration, and accelerated biological aging long before conventional diagnosis.
