What Is Tap Water?

Tap water is the water delivered to your home through municipal water systems. In the United States, tap water is regulated by the Environmental Protection Agency (EPA), which sets standards for over 90 contaminants including bacteria, viruses, chemicals, and metals.

Municipal Water Treatment Process

Before reaching your faucet, tap water undergoes extensive treatment at municipal facilities. The typical process includes:

1
Coagulation and Flocculation
Chemicals are added to cause particles to clump together for easier removal.
2
Sedimentation
Heavy particles settle to the bottom and are removed.
3
Filtration
Water passes through filters to remove smaller particles, bacteria, and parasites.
4
Disinfection
Chlorine, chloramine, or other disinfectants are added to kill remaining pathogens and prevent regrowth in the distribution system.

What Remains in Tap Water

While treatment removes many contaminants, tap water still contains several substances:

Disinfection chemicals: Chlorine or chloramine used to keep water safe during distribution
Minerals: Calcium, magnesium, and other naturally occurring minerals (contributes to water hardness)
Fluoride: Added in many municipalities to support dental health
Trace contaminants: May include PFAS, lead from old pipes, or agricultural runoff depending on location

South Florida Tap Water

In South Florida, tap water is sourced primarily from the Biscayne Aquifer. While it meets EPA standards, it is known for being hard (high mineral content) and is treated with chloramine rather than chlorine. Many residents notice a distinct taste and choose filtration or alternative water sources.

What Is Alkaline Water?

Alkaline water is water with a pH level above 7, typically ranging from 8 to 9.5 or higher. The higher pH makes it less acidic than neutral water and gives it distinct characteristics that set it apart from regular tap water.

How Alkaline Water Is Produced

There are several methods for creating alkaline water:

Ionization (Electrolysis)

Water passes through an electrolysis chamber where an electrical current separates it into alkaline and acidic streams. This process:

Raises pH to 8-11
Creates negative ORP (antioxidant potential)
Concentrates beneficial minerals
Produces fresh, active alkaline water

Mineral Addition

Alkaline minerals such as calcium, magnesium, or potassium are added to purified water. This method:

Raises pH to 8-10
Adds beneficial minerals
Does not create negative ORP
Provides stable pH over time

Key Characteristics of Alkaline Water

Elevated pH: Typically 8 to 9.5+, making it less acidic than tap water
Mineral content: Contains calcium, magnesium, and potassium that contribute to taste and potential benefits
Negative ORP (ionized only): Indicates antioxidant potential, measured in millivolts
Clean taste: Filtration removes chlorine and other chemicals that affect flavor

pH Comparison: What the Numbers Mean

pH measures how acidic or alkaline a substance is on a scale from 0 to 14, with 7 being neutral. Understanding pH helps clarify one of the key differences between tap water and alkaline water.

pH Scale: Tap Water vs Alkaline Water

0714

Tap: 6.5-7.5

Alkaline: 8-9.5+

ACIDICNEUTRALALKALINE

Note: The pH scale is logarithmic. Water at pH 9 is 10 times more alkaline than water at pH 8, and 100 times more alkaline than neutral pH 7 water.

Tap Water pH: 6.5-7.5

The EPA requires municipal water to have a pH between 6.5 and 8.5, though most tap water falls in the 6.5 to 7.5 range. This is considered neutral to slightly acidic. Factors affecting tap water pH include:

Source water characteristics (groundwater vs surface water)
Treatment chemicals added during purification
Piping materials in the distribution system and your home

Alkaline Water pH: 8-9.5+

Alkaline water typically has a pH between 8 and 10, though Hydralife water is maintained at 9.5+ for optimal balance between alkalinity and drinkability. At this pH level:

The water is noticeably less acidic than tap water
Taste is often described as smoother and silkier
The level is considered safe for regular consumption

Important Clarification

While alkaline water has a higher pH than tap water, drinking it will not significantly change your body's overall pH. Your body maintains strict control over blood pH (7.35-7.45) regardless of what you consume. However, alkaline water may have localized effects in the digestive system.

Taste Comparison: Why Alkaline Often Tastes Better

One of the most noticeable differences between tap water and alkaline water is taste. Many people who try alkaline water for the first time comment on its distinctly different mouthfeel and flavor profile.

Tap Water Taste

Chemical taste from chlorine or chloramine
Metallic notes from pipes in older homes
Varies significantly by location
Can taste flat or heavy when warm

Alkaline Water Taste

Smooth, silky mouthfeel
No chemical aftertaste
Slightly sweet undertone from minerals
Consistently clean taste

Why Does Alkaline Water Taste Different?

Several factors contribute to the taste difference:

1
Filtration removes off-tastes: Multi-stage filtration eliminates chlorine, chloramine, and other chemicals responsible for tap water's taste.
2
Minerals add subtle flavor: Calcium, magnesium, and potassium contribute a slightly sweet, rounded taste profile.
3
Higher pH affects mouthfeel: The alkaline nature creates a smoother, less harsh sensation when drinking.

Better Taste Means Better Hydration

Many people drink more water when they enjoy its taste. If alkaline water tastes better to you, you may naturally increase your daily water intake, which provides health benefits regardless of the water type.

Mineral Content: What Each Contains

Both tap water and alkaline water contain minerals, but the types, amounts, and bioavailability can differ significantly based on source and processing.

Minerals in Tap Water

Tap water mineral content varies greatly depending on the source. South Florida water, sourced from the limestone-rich Biscayne Aquifer, tends to be hard, meaning it contains high levels of calcium and magnesium. While these minerals are not harmful, they contribute to scale buildup and can affect taste.

Common minerals in tap water include:

Calcium: Contributes to hardness; varies by location
Magnesium: Also contributes to hardness
Sodium: Usually low levels
Fluoride: Added intentionally in many areas

Minerals in Alkaline Water

Quality alkaline water contains controlled amounts of beneficial minerals that are either naturally present or added during processing:

🦴

Calcium

Supports bones, teeth, muscle function

💪

Magnesium

Aids muscle and nerve function, energy production

❤️

Potassium

Supports heart health, fluid balance

Bioavailability Note

Minerals in water are generally highly bioavailable, meaning your body can absorb them efficiently. While water should not be your primary mineral source (food is more important), the minerals in alkaline water can contribute to your daily intake in a readily absorbable form.

Frequently Asked Questions

Here are answers to common questions about choosing between tap water and alkaline water.

Municipal tap water in South Florida meets EPA safety standards and is considered safe to drink. However, it may contain treatment chemicals like chloramine, have hard water minerals, and occasionally contain trace contaminants like PFAS. Many residents prefer filtered or alkaline water for improved taste and peace of mind.

Some studies suggest alkaline water may hydrate more effectively, particularly after exercise. A 2016 study found improved hydration markers in participants drinking high-pH water. However, any water that encourages you to drink more will improve your hydration overall.

Yes, you can raise tap water pH by adding baking soda, using alkaline drops, or purchasing a home ionizer machine. However, these methods vary in effectiveness and do not provide the same multi-stage filtration and ionization as professional alkaline water production.

Municipal water treatment facilities add chlorine or chloramine to disinfect water and keep it safe through the distribution system. South Florida primarily uses chloramine, which has a different taste than chlorine. The taste is more noticeable when water is warm or when you first turn on the tap.

This depends on your priorities. If you value improved taste, mineral content, filtered water quality, and the convenience of delivery, many find it worthwhile. For those on tight budgets who are satisfied with tap water taste, it may not be necessary. Consider trying alkaline water to see if you notice a difference.

Many people report that alkaline water improves the taste of coffee, tea, and cooked grains like rice. The higher pH and mineral content can enhance flavors and may make certain foods taste less bitter. It is worth experimenting to see if you notice improvements in your recipes.

Conclusion: Making Your Choice

Both tap water and alkaline water can be part of a healthy hydration routine. Tap water offers unbeatable convenience and cost, while alkaline water provides enhanced taste, mineral content, and removal of treatment chemicals that many find valuable.

For South Florida residents dealing with hard water and chloramine taste, alkaline water delivery offers a compelling alternative that many find worth the investment. The key is finding what works best for your lifestyle, budget, and health goals.

If you are curious about the difference, the best way to decide is to try alkaline water and see if you notice improvements in taste and how you feel. Many of our customers report they drink more water simply because they enjoy it more.
