This might happen when the water entering the house is colder than the inside temperature. Cold water contains more oxygen than warm water, so when cold water from the water mains outside warms up in our warm houses, the oxygen must escape. Milky water is caused by air bubbles rising to escape the water.

Both federal and state agencies regulate drinking water. The Environmental Protection Agency (EPA) enforces the 1974 Safe Drinking Water Act (SDWA) revised in 1986 and 1996. For more information on drinking water rules and regulations, please visit our Regulatory Affairs page. 

These whitish specks are possibly hot water heater dip tube pieces. Many 1980s hot water heaters had a defective dip tube that disintegrates with time. The dip tube transports cold water from the hot water heater's top to the bottom for heating. Over time, the dip tube breaks down and white particles enter domestic pipes. If large enough, particles become stuck in sink faucet or showerhead strainers. If they're from the dip tube, these particles won't be in the toilet bowls, tanks, or automatic ice maker because they only affect hot water. Call your hot water heater manufacturer for help with this issue.

No, customers must take precautions to remove or neutralize chloramines and free chlorine in water used in fish tanks and ponds.

Dialysis patients can safely drink water treated with either free chlorine or chloramines.

To remove chlorine smell and taste from tap water, fill a pitcher with water and leave it uncovered on your counter or in your refrigerator. Within a couple of hours, the chlorine will dissipate. 

Every spring, the City of Manassas and Fairfax Water, the drinking water suppliers to Prince William Water, temporarily switch from using chloramines as the main disinfectant in their water treatment process to free chlorine. According to our water suppliers, this short-term change is a best practice for the drinking water industry and makes it easier to implement a flushing program for the distribution system.
