Jacksonville Electric Authority (JEA Major Grid)

Met federal legal limits in the latest quarter the EPA assessed (April 2024 - June 2024). Legal doesn't mean the water meets today's health guidelines: most legal limits haven't moved in about 20 years, and many of these chemicals have none. Duval County, FL.

What Takes It Out

EWG lists which home filter technologies reduce each contaminant. Counted against this utility's report:

Reverse osmosis

6 of 6

contaminants above the guideline, plus 17 other detected. Reverse osmosis is the drinking water system under the sink.

Reverse Osmosis

Activated carbon

4 of 6

contaminants above the guideline, plus 5 other detected. Activated carbon is the whole-house filter on the main line.

Whole-House Filtration

Ion exchange

3 of 6

contaminants above the guideline. Ion exchange is what a water softener does; it also takes out the hardness that scales your fixtures.

Water Softeners

A complete system stacks all three: carbon on the main line, a softener, and reverse osmosis at the kitchen sink. One flat price, installed by a licensed plumber near you.
