Nothing in EPA’s and Florida’s records for this utility is above a health goal. That covers nitrate, arsenic and other regulated chemicals, plus lead and copper, not everything. 4 health-based violations since 2016.

What was found

Total trihalomethanes (TTHM), haloacetic acids (HAA5), fluoride, nitrate, arsenic, chromium (total) and uranium: Florida’s own results, samples taken from July 29, 2020 to July 8, 2024, with EPA’s 2012 to 2019 file for earlier years.

What this report can’t tell you

  • Everything else. Total trihalomethanes (TTHM), haloacetic acids (HAA5), fluoride, nitrate, arsenic, chromium (total) and uranium results here are Florida’s own from 2020 on, with EPA’s national file for 2012 to 2019. Lone Oaks Mobile Estates’s own annual report, which it must send you every year, has the contaminants this page does not show.

  • Your own plumbing. Lead results are the 90th percentile across homes the utility samples. Your home’s service line, solder and fixtures decide yours. A certified lab test is the only way to know.

  • What it means for your health. This page reports what the records show and EPA’s limits and goals; it is not medical advice. If you are worried about a health effect, talk to a doctor or your local health department.

  • Anything after the latest data. SDWIS data is from 2026 Q3; UCMR 5 didn’t sample this utility; Florida’s results run from July 29, 2020 to July 8, 2024.

Testing your own tap

Lone Oaks Mobile Estates’s results are for the water it sends out. What your own service line, solder and fixtures add shows up only in a test of your tap, by a lab Florida certifies.

No lab Florida certifies is within 75 miles of the area Lone Oaks Mobile Estates serves on the state’s list. Some take samples by mail; the state’s page lists them all.

Florida Department of Health Bureau of Public Health Laboratories: Coliform and E. coli testing for private wells at the Jacksonville and Miami labs. Collection kits come from your county health department, and the sample has to reach the lab on ice the same day it is collected. $40 for private testing through the state lab.
