Is San Jose Water Safe to Drink - San Jose Water Quality

San Jose water is full of chemicals, most of which cause cancer.

Drinking unfiltered water from city water sources could be hazardous to your health.

Now let’s dive deeper into San Jose water quality.

San Jose Water Quality

San Jose has a total of 30 contaminants analyzed by the Environmental Working Group, a consumer advocacy nonprofit.

15 of these 30 contaminants are rated as exceeding health guidelines.

They include things like Barium, Chloroform, and Radium.

Most of the 30 contaminants pose a risk of Cancer if allowed to stay in your drinking water.

So, What Can You Do?

Information about water quality can be surprising and unsettling.

But there’s no reason to lose hope. There are things you can do today in your household to keep you and your family safe and healthy.

In Your Household:

Use Berkey water filters with activated carbon to filter out 26 of the 30 contaminants, or 86.7 percent, in your drinking water.

Brita and PUR pitchers only manage 46.7% or 14 out of 30.

A whole house filtration system will also filter out 27 of the 30 contaminants, or 90 percent, making a Berkey filter the better choice.

A few things to note: Whole house systems are much more effective than water pitchers like Brita and PUR.

However, the initial cost is higher and they require installation.
