Questions About Your Water Quality

Does my water have fluoride added to it?

Yes, all of Padre Dam’s potable water has fluoride added to it before entering Padre Dam’s distribution system. Read more about Fluoridation.

Why does my water look cloudy / foggy?

Air in the water or pipes creates small bubbles in the water that are harmless. Try pouring some water into a clear glass and let it sit for a minute. As the bubbles leave the water, the water will become clearer. If cloudiness is still an issue call (619) 448-3111.

Is my drinking water safe? Do I need bottled or filtered water for safety?

Padre Dam water meets all water quality regulations and is absolutely safe to drink. Bottled water is regulated by the U.S. Food and Drug Administration (FDA) while Padre Dam's water is regulated by the U.S. Environmental Protection Agency (EPA) and the California Department of Public Health (DPH). Tap water is actually required to meet stricter reporting requirements. Also, tap water costs a fraction of the cost of bottled water. The decision to drink bottled water or use a filtration system should be based on your particular taste preference.

Why does my water have a different odor than normal?

Generally, this smell is coming from the drain and not the water. The odor is probably coming from a drain with materials such as food or hair stuck to the walls of the drain pipe. If you have been away for a few days, you may just need to flush out the line by running the water for a couple minutes. To get rid of the odor, you can pour about a half cup of bleach down the drain. You will need to do this at every sink with the odor.

Granules and/or other small particles are clogging my faucets and shower heads. What should I do?

If the particles are not showing up in the bottom of your toilets (which are connected to the cold water pipes) this is probably a hot water heater problem. You may need to flush out your water heater. When draining the water heater you will probably see a lot of debris coming out. When the water is heated, the small particles precipitate out and will settle in the bottom of the water heater. These particles can become agitated and be swept into hot water fixtures in your home.

It is recommended that a water heater be flushed every six months. Use caution when flushing your water heater as sometimes the debris in the tank can prevent the drain valve from fully closing. A licensed plumber can be helpful in resolving any issues you may have with your water heater.  

Is the water safe for my animals?

Yes, except for fish. Padre Dam’s drinking water does contain chloramines which is a combination of chlorine and ammonia that serves as a disinfectant for your water. Chloramines kill bacteria and will be harmful to fish. When you use your drinking water for fish tanks, you will need to purchase water treating products from the local pet supply store that will neutralize the chloramines before putting your fish in the water. Chloramines do not affect other animals and is safe for them to drink.
