If you’re curious about the quality of San Jose tap water, keep reading!
Where Does San Jose Tap Water Come From?
San Jose tap water comes from three main sources. First, groundwater is pumped from more than 100 wells around the Santa Clara Groundwater sub-basin. Next, local mountain surface water is collected and treated with all other San Jose tap water. Finally, surface water is imported from the Santa Clara Valley water District. This water is a product of Sierra snowmelt and is treated locally after traveling through federal and state water projects to get to San Jose.
Can you Drink San Jose Tap Water?
San Jose tap water goes through a cleaning process like every other city. While many contaminants are removed in the treatment process, other contaminants arise as a result of cleaning the water. Others form or collect from the treatment plant in the pipes on the way into your home. So, while the water may pass water testing in the treatment plant, there are still pollutants in your water. For example, there are lead pipes that pass water from treatment center to homes in San Jose. This can cause lead to get in the water, which can lead to a number of unfortunate health concerns. One of the best ways to avoid these pollutants is with a water filter.
Not only will a water filter help to remove lead, it can take away any unnecessary smells in your water and can even improve the overall taste of your water, too. A water filter is an easy way to improve the water in your home and to ensure that the water is consistently safer to use and drink for everyone in your family.

With this in mind, you should definitely opt for protection and use a water filter when using San Jose tap water.

- Aluminum – This metal can lead to the impairment of brain development in children
- Barium – A mineral that can contribute to causes for hypertension or cardiovascular disease
- Bromochloromethane – As a byproduct of disinfection this can increase the risk for cancer
- Chlorate – Another result of disinfection that can lead to impairments in thyroid functioning
- Chromium (total) – This is generally in tap water due to industrial usage.
- Dibromoacetic acid – As one of five haloacetic acids, this can cause problems during pregnancy and increase the risk of cancer. Additional haloacetic acids that are present include monobromoacetic acid and monochloroacetic acid
- Fluoride –Fluoride is regularly added to water, but it can occur naturally
- Haloacetic acids (HAA5) – The group of five acids, some of which have been listed, are a byproduct of disinfection and can cause cancer.
- Manganese – This common element, often found in water, can impair the attention span or memory of children.
- Molybdenum – Gout-like symptoms can occur with too much exposure from this naturally occurring metal
- Nitrate – This is a fertilizer chemical. It can cause cancer and oxygen deprivation in infants.
- Nitrate and Nitrite – A product of urban runoff, these toxins can cause oxygen deprivation in young children and can increase the odds of cancer.
- Strontium – This metal forms to your bones and can increase the chance of bone cancer
