Starkey E . 2025. Assessment of estuarine water quality at Cumberland Island National Seashore: 2022 data summary. Science Report. NPS/SR—2025/238. National Park Service. Fort Collins, Colorado. https://doi.org/10.36967/2308358

In July 2022 the Southeast Coast Network assessed water-quality at Cumberland Island National Seashore as part of the National Park Service Vital Signs Monitoring Program. Monitoring was conducted following methods developed by the Environmental Protection Agency (EPA) as part of the National Coastal Assessment Program (EPA 2014). Laboratory analysis measured chlorophyll a and total and dissolved concentrations of nitrogen and phosphorous. Field measurements included water temperature, pH, dissolved oxygen, and salinity. Water clarity, which requires a Secchi depth measurement, was calculated when possible. All measured parameters were rated as good, fair, or poor based on thresholds set by the EPA (2012). The purpose of this document is to report the most recently collected data from the seashore as part of an ongoing long-term water-quality monitoring program. This report was designed to provide water-quality monitoring data to managers as a concise summary in the context of applicable federal standards developed by the EPA. Previous synoptic assessments of water-quality conditions at Cumberland Island National Seashore were conducted in July 2007, August 2012, and August 2017 as part of I&M monitoring efforts.
