The short answer
Nothing in EPA’s and CDC’s records for this utility is above a health goal. That covers nitrate, arsenic and other regulated chemicals, plus lead and copper, not everything. 1 health-based violation since 2016.
What was found
Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 4.0 ppm, for the period ending Dec. 31, 2007. None since is on file, so it is not counted as a current finding.
Arsenic, haloacetic acids (HAA5), nitrate and total trihalomethanes (TTHM): North Carolina’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2020 to 2023.
Fluoride, chromium (total) and uranium: EPA’s compliance monitoring file, samples taken from Nov. 7, 2013 to Nov. 25, 2019. Newer results are in the utility’s annual water quality report.
Below EPA’s limits1
Fluoride
Forms or is added in treatment
0.19ppm
Highest yearly average, 2013 to 2019
2019 average: 0.18 ppm
Averaged by year, the highest was 0.19 ppm, in 2016, below EPA’s legal limit of 4.0 ppm. In 2019, the latest year on file, its two samples averaged 0.18 ppm.

What this report can’t tell you
Everything else. Arsenic, haloacetic acids (HAA5), nitrate and total trihalomethanes (TTHM) results here are North Carolina’s yearly averages as CDC publishes them, from 2020 on, with EPA’s national file for 2012 to 2019. Fluoride, chromium (total) and uranium come from EPA’s file alone, which ends in 2019. Figure 8 Island’s own annual report, which it must send you every year, has newer results for those and 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; CDC’s yearly averages for North Carolina cover 2020 to 2023; EPA’s compliance samples are from Nov. 7, 2013 to Nov. 25, 2019.
