Does Marietta have Lead contamination?
Testing data for Marietta has not been provided to state or federal databases. Information about this utility’s compliance with lead testing is not available. Contact the utility directly to find out about lead testing results.
General information about Lead:
The legal limit for lead is 15 parts per billion. Being well-below this level is a good thing.
- Concentrations between 3.8 ppb and 15 ppb put a formula-fed baby at risk of elevated blood lead levels. Read more about the symptoms of Lead in water.
There is no safe level of lead for humans.
- The good news is that 99.99% of the lead can be filtered out.

What Can You Do?
Information about water quality in Marietta can be surprising.
But there are things you can do in your home to clean up your water.
To Remove Lead and Other Contaminants In Your Home:
There is one solution that beats Brita, PUR, and expensive whole house systems.
- It costs less per gallon.
- Needs fewer filter changes.
- And it doesn’t make your water taste weird.
- Use Berkey filters with activated carbon to filter out at least 90% of contaminants in your drinking water.
- Berkey filters can also remove up to 99.99% of any Lead in Marietta water.
- Brita can filter 9 of 13 contaminants and Lead depending on the filter.
- Note: We may receive a commission if you decide to purchase filters through links on this page.
- To filter out 11 of the 13 contaminants in your whole house, consider a Reverse Osmosis water filtration system for your home.
- These are more expensive than pitchers to purchase, but can be more effective.
- They have the benefit of filtering out heavy hitters like:
- Bromodichloromethane – byproduct of the chlorine disinfection process*
- Haloacetic acids (HAA5)
- Haloacetic acids (HAA9)
- Hexavalent chromium
- Total trihalomethanes – byproduct of chlorination*
- Trichloroacetic acid
*Chlorination is an effective method of disinfecting/treating drinking water. You can then use a water filter to reduce the effects of chlorination byproducts to get the safest, cleanest water possible.
