Water Supply & Source Water Protection
Protect your source water because our community depends on a reliable supply of safe, high-quality drinking water!
Did You Know? A consistent supply of high-quality source water is safer and is easier & much more cost-effective to treat.
What is source water?
Source water is a raw, untreated supply of water – typically surface water or groundwater – used for current or potential future drinking water. For Fairfax Water customers, your source water is the Potomac River or Occoquan Reservoir.
What is source water protection?
Source water protection is a proactive approach to safeguarding, maintaining, or improving the quality and/or quantity of drinking water sources and their contributing areas.
Why is source water protection important?
Water utilities rely on sustainable sources of water that can be treated to provide reliable, high-quality drinking water. Source water protection is the first of several barriers to ensure safe drinking water, followed by other components of a multi-barrier approach that includes effective water treatment, secure distribution systems, and monitoring and evaluation.
Source water protection provides many benefits, including public health protection and watershed improvements. It involves identifying potential threats to drinking water, assessing the risk associated with those threats, and establishing proactive measures that can help address them.

Tip - Protect the Watershed
Limit the use of fertilizer. If you must fertilize your lawn, choose a product without phosphorous, which along with nitrogen, upsets the balance of nutrients in local waterways.
Tip - In the Bathroom
Test for toilet leaks by adding food coloring to the water tank. Don’t flush for 15 minutes. If there is color in the bowl after 15 minutes, you may have a leak.
Tip - Outdoor Tips
Shut off and drain the water lines to outside spigots in the winter. This prevents freezing temperatures from causing expensive leaks.
