Can You Drink Washington DC Tap Water?
[Updated: June 13, 2023]
Washington DC water quality ranks in the mid to high range for contaminants.
- For reference, Miramar, Florida has 75 contaminants. (The most of any U.S. city over 50,000.)
- Rochester Hills, Michigan has 5.
- Note: These are both outliers.
With a total of 36 contaminants in your drinking water, 12 of those exceed health guidelines.
Drinking unfiltered water from Washington DC water sources could be hazardous to your health.
Let’s look closer at DC water quality.
Washington DC Water Quality
Washington has a total of 36 contaminants analyzed by the Environmental Working Group (ewg.org).
12 of these 36 contaminants are rated as exceeding health guidelines.
They include things like Arsenic, Chloroform, and Nitrates.
Most of the 36 contaminants pose a risk of Cancer if allowed to stay in your drinking water.
Lead in DC Water
Washington DC drinking water has lead in it.
90 percent of samples taken from DC water sources had a lead concentration of 2.7 parts per billion (ppb) or less.
This is a very low level of lead contamination when compared to other cities. That’s great!
Here is how to compare Washington’s lead levels to risky levels.
Lead concentrations of 3.9 ppb to 15 ppb “put a formula-fed baby at risk of elevated blood lead levels.” (ewg.org)
Here are a few of the lead poisoning symptoms for children under 6:
- Abdominal Pain
- Developmental Delay
- Learning Difficulties
- Weight loss
- Hearing loss
There is no safe level of lead for humans.
So, What Can You Do?
Information about D.C. water quality can be surprising.
There are things you can do today to keep you and your family safe and healthy.
In Your Household:
- Use Activated Carbon filters to remove most contaminants in your drinking water.
- Alternatively, use Berkey water filters with activated carbon to filter out 28 of the 36 contaminants, or 77.8 percent, in your drinking water. (They also remove 99% of lead contamination in Washington DC water.)
Washington DC Whole House Water Filtration Systems
A whole house filtration system will filter out 32 of the 36 contaminants, or 88.9 percent, making it another effective choice.
A few things to note:
- Whole house systems are much more effective than water pitchers like Brita and PUR.
- However, the initial cost is higher and they require installation.
For a list of the contaminants that can be filtered out by a whole house system, go to Washington DC’s Water Quality page.
