Is Louisville Water Safe to Drink?
Louisville water quality ranks in the low-mid range for contaminants.
- For reference, Rochester Hills, Michigan has 5 contaminants.
- Miramar, Florida has 75 contaminants. (The most of any U.S. city over 50,000.)
- Note: These are both outliers.
With a total of 21 contaminants in your drinking water, 8 of those exceed health guidelines.
Contaminant levels have increased from 16 to 21 within six years.
Drinking unfiltered water from Louisville water sources could be hazardous to your health.
Let’s look closer at Louisville water quality.
Louisville Drinking Water Quality
Louisville has a total of 21 contaminants analyzed by the Environmental Working Group (ewg.org).
38.1% of contaminants are rated as exceeding health guidelines.
They include things like Chlorite, Chromium, and PFOA.
Most of the contaminants pose a risk of Cancer if allowed to stay in your drinking water.
Lead in Louisville Water
Louisville drinking water has unsafe levels of lead in it.
90 percent of samples taken from Louisville water sources from 2015 – 2017 had a lead concentration of 4.7 parts per billion (ppb) or less.
- Lead concentrations of 3.9 ppb to 15 ppb “put a formula-fed baby at risk of elevated blood lead levels.” (ewg.org)
- El Paso, Texas has lead concentrations up to 84 parts per billion.
- Portland, Oregon has lead concentrations up to 52.4 parts per billion.
- The legal limit for lead is 15 ppb. The city is not legally required to mitigate unless levels pass 15 ppb.
There is no safe level of lead for humans.
Here are a few of the lead poisoning symptoms for children under 6:

So, What Can You Do?
Information about 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 Berkey water filters with activated carbon to filter out 62.5 percent of contaminants in your drinking water.
(They also remove up to 99% of lead contamination in Louisville water.)
Basic pitchers like Brita and PUR only manage 56.25%.
Save money on new and replacement filters when you use the links at waterbadge.com/filters.
Louisville Whole House Water Filtration Systems
A whole house filtration system can filter out 85.7 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 Louisville’s Water Quality page.
