Tahoe Artesian Water™ meets all applicable state and federal requirements for water quality, MCLs, PHGs, and Primary Drinking Water Standards.  Our water is rigorously tested to ensure that only the highest quality of water is sold.  


Tahoe Artesian Water™ is sourced from a single private protected source. Snow from California’s Sierra Nevada Mountains filters through miles of rock before pressurizing itself in a 500 foot deep granite aquifer. Tahoe Artesian Water™ is not spring water or well water; instead it is artesian water, meaning that the water is pressurized upwards through the granite and reaches the surface by its own power. Because the water is not pumped or leached through the dirt (like spring water) it maintains exceptionally high water quality standards.


Tahoe Artesian Water™ flows under pressure from a single artesian well located in a granite aquifer situated 500 feet below ground, through the well-head directly to our single-serving bottles.   Because our water is propelled to the surface under natural pressure, through granite it does not need to be filtered, ozoned, distilled or subjected to reverse osmosis.  Despite our water‘s purity, California Health and Safety Code Section 111075 (b) requires all water (regardless of quality) flow through minor filter and germ treatment.  As a result, we have small sediment filters and UV rays which maintain the natural qualities of the water while meeting California’s strict standards. 

In addition, because our water is filled directly from untouched well piping, no equipment (either human hands, pumps or other machinery) is needed, and the water is deposited directly into the serving bottles.   This pristine environment and hands-free method lets us keep our water simple and clean.  We start with high quality water,  pipe it in small quantities, in small batches, and offer it to our drinking public. 


  • Statement of Quality refers to the highest level(s) of contaminant(s) which are allowed in a container of bottled drinking water, as established by the United States Food and Drug Administration and the California Department of Public Health, as well as standards protective of public health and public drinking water, as established by the U.S. Environmental Protection Agency and the California Department of Public Health.
  • Maximum Contaminant Level (MCL)  refers to the the highest level(s) of a contaminant(s) which are allowed in drinking water, as established by the U.S. Environmental Protection Agency and/or the California Department of Public Health.  Primary MCLs are set as close to the Public Health Goals (PHGs) as is economically and technologically feasible.
  • Public Health Goal (PHGs) refers to the level(s) of contaminant(s) in drinking water below which there is no known or expected risks to public health. PHGs are set by the California Environmental Protection Agency.
  • Primary Drinking Water Standard refers to the MCLs for contaminant(s) which affect public health, their monitoring and reporting requirements, and and water treatment requirements, as established by the U.S. Environmental Protection Agency or the California Department of Public Health.

Our product has been thoroughly tested in accordance with federal and California law. Our bottled water is a food product and cannot be sold unless it meets the standards established by the U.S. Food and Drug Administration and the California Department of Public Health. The following statements are required under California law:

“Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the United States Food and Drug Administration, Food and Cosmetic Hotline (1-888-723-3366).” 

“Some persons may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons, including, but not limited to, persons with cancer who are undergoing chemotherapy, persons who have undergone organ transplants, persons with HIV/AIDS or other immune system disorders, some elderly persons, and infants can be particularly at risk from infections. These persons should seek advice about drinking water from their health care providers. The United States Environmental Protection Agency and the Centers for Disease Control and Prevention guidelines on appropriate means to lessen the risk of infection by cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (1-800-426-4791).” 

“The sources of bottled water include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water naturally travels over the surface of the land or through the ground, it can pick up naturally occurring substances as well as substances that are present due to animal and human activity. Substances that may be present in the source water include any of the following: 

  1. Inorganic substances, including, but not limited to, salts and metals, that can be naturally occurring or result from farming, urban storm water runoff, industrial or domestic wastewater discharges, or oil and gas production. 
  2. Pesticides and herbicides that may come from a variety of sources, including, but not limited to, agriculture, urban storm water runoff, and residential uses. 
  3. Organic substances that are byproducts of industrial processes and petroleum production and can also come from gas stations, urban storm water runoff, agricultural application, and septic systems. 
  4. Microbial organisms that may come from wildlife, agricultural livestock operations, sewage treatment plants, and septic systems. 
  5. Substances with radioactive properties that can be naturally occurring or be the result of oil and gas production and mining activities. 

In order to ensure that bottled water is safe to drink, the United States Food and Drug Administration and the State Department of Public Health prescribe regulations that limit the amount of certain contaminants in water provided by bottled water companies.”
