Safety & Handling

Safety & Handling

Over the course of the last several years, we have been reducing the plastic in our bottles and caps, making our packaging lighter and more environmentally friendly.. In light of that, consumers should be advised that small parts, including our caps, should not be put in the mouth. And, that caps should always be replaced securely on bottles when not in use or discarded promptly.

Mountain Oasis Water Service provides consumers of all ages with healthy, Purified, Hot & Cold options to enjoy any time of day. The safety and quality of our bottled water products are our top priorities. We regularly conduct tests on all of our bottles and our waters for safety, quality and performance.

Water Source Identification

Oasis Water identifies water sources on its bottle labels and/or online.

Purified water products are treated by reverse osmosis and ozone disinfection for added safety assurance and some of our products are enhanced with minerals for consistent and pleasing taste. Bottled water products from each  bottling line are tested many times per day to ensure quality.

Quality Reports

Since 2017, we have made quality reports publicly available for all of our bottled water brands based on independent testing results from certified laboratories. Reports may be obtained by email to:, or by mail at P.O. Box 5224 Sonora, CA 95370. You may also visit our office at 14216 Tuolumne Rd. #2 Sonora, CA,95370

Storage and Handling

To maintain the high quality of our bottled water products, we recommend people store all of our products in a cool, clean, or shaded location, as they would any other packaged food product.

Food Packaging Safety & Regulation

We use packaging that fits into the lifestyles of today’s busy consumers and is considered safe by regulatory and public health agencies. We evaluate new packaging materials and make changes to our products when we believe there is a clear environmental, health and/or economic benefit.

The State of California Food and Drug Branch (FDA) is responsible for overseeing the safety of bottled water, which, like other food products such as infant formula and seafood, must be processed, packaged, shipped and stored in a safe and sanitary manner, and be truthfully and accurately labeled. Bottled water is one of the most regulated food products, with ABBS protocols specific to bottled water processing and labeling.

Chemicals from plastic packaging can migrate over time, but the U.S. Food & Drug Administration (FDA) sets conservative limits for the amounts it considers safe for human consumption. Oasis Water complies with international packaging and health-based regulations.

Recycling and Reuse of Bottles

Our 5-gallon home and office delivery containers are made of  PET plastic and are each vigorously cleaned and reused as many as 35 times before they’re recycled.
