What is San Antonio’s Water Quality?

San Antonio Water Quality - WaterBadge

San Antonio water quality is very low with 35 total contaminants, many of which cause Cancer.

We wouldn’t recommend taking a drink directly from San Pedro Creek without running it through a filtration system first.

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

Contaminants in San Antonio’s Water

San Antonio’s 35 water contaminants have been analyzed by the Environmental Working Group, a consumer advocacy nonprofit.

15 of these 35 contaminants are rated as exceeding health guidelines.

They include things like Chloroform, Radium, and Uranium.

Most of the 35 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 29 of the 35 contaminants, or 82.9 percent, in your drinking water.

Purified Water. Peace of Mind. Berkey Filters.

You may already have a decent pitcher with activated carbon.

Filter Even More

To filter out 32 of the 35 contaminants, or 91.4 percent, consider a whole house water filtration system for your home.

A few things to note: These filters are much more effective than water pitchers.

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

To filter out 91.4% of contaminants, use our recommendations on the WaterBadge Filters page:
