You have learned your tap water might contain harmful substances like chlorine, heavy metals, pesticides, and even emerging contaminants like PFAS (fluorinated compounds) in previous posts about Water. Depending on where you live, your water could pose health risks unless you take proactive steps to protect yourself and your family.  

In this post, I’ll guide you through the essentials: how to identify what’s in your water, the best filtration systems for your needs, and why investing in clean water is one of the smartest health decisions you can make.

Step 1: Know What’s in Your Water  

Understanding your local water quality is critical. What contaminants might be lurking in your water? How can you remove them effectively?  

How to Check Water Quality in Your Area  

In Japan:

Local municipalities provide detailed water quality reports. For example, the [Tokyo Waterworks Bureau] publishes a comprehensive water quality report that includes residual chlorine levels.  

In the U.S. :

The Environmental Working Group (EWG) offers a [National Tap Water Quality Database]with detailed analysis for your area.  

Once you know your water’s contaminants, you can choose a filtration method that works for you.

Step 2: Choose the Right Filtration System  

Not all water filters are created equal. Here’s an overview of popular options and their benefits:  

1. Reverse Osmosis (RO) Filters

– Removes fluoride, nitrates, lead, and copper with NSF certification.  

– Drawback: Strips water of essential minerals, leaving it as “dead water.” Solution? Add a pinch of sea salt for mineral replenishment.  

2. Distilled Water Systems

– Purifies water by heating it into steam and condensing it back into liquid.  

– Effective at removing large particles like heavy metals, but less effective against endocrine-disrupting chemicals and volatile organic compounds (VOCs).  

3. Solid Block Carbon Filters

– EPA-recommended for removing chemicals like pesticides, herbicides, VOCs, and heavy metals.  

– My personal favorite: the Berkey Filter. It’s gravity-fed (great for emergencies), made of stainless steel, and can even purify rainwater or pond water.  

4. Simple Filters (e.g., BRITA)

– Affordable but limited in effectiveness. Removes some chlorine and heavy metals but doesn’t fully eliminate unpleasant tastes or ensure safety.

Why I Avoid Bottled Water  

I never drink bottled water—and here’s why:  

1. Environmental Impact: The production and disposal of plastic bottles are major contributors to pollution.  

2. Health Risks: Bottles may leach BPA, a known endocrine disruptor linked to cancer and other health issues.

Please Please Please stop drinking plastic bottled water. Carry your own Water bottle.

Thinking Beyond Drinking Water  

Did you know the water in your shower and bath could harm you too? Chlorine, when heated, creates trihalomethanes—carcinogens that can be absorbed through your skin or inhaled as steam. Installing filters for your bathroom water can further protect your health.

Advanced Options for Health Enthusiasts  

For those looking to go beyond standard filtration:  Price from $1,500 – 5,000

– Re-Structured Water Systems (Kaiki-Sui): I used this in the past in New York. Actually amazed by its effects. It is supposed to create high frequency water. When vegetables are soaked in this water, I saw oils and other still floated in the surface. ( I was told this was herbicides and pesticides) Mimics high-quality natural spring water and claims to improve produce freshness, reduce toxins, and even extend flower life.  

– Kangensui: Alkaline water made via electrolysis, touted for its potential health benefits. However, more research is needed to confirm its effectiveness.

Clean Water, Healthy Life  

Your health starts with the water you consume daily. By understanding what’s in your tap water and investing in the right filtration system, you can make a lasting impact on your well-being.  

Start small—filter your drinking water first. Then consider extending your efforts to shower and bath water. Together, these steps can significantly reduce your exposure to harmful substances.
