Projects typically range from 1 to 3 years in duration and fall into one of three categories:
One-year efforts for purposes of installation of instrumentation, training and quality assurance, scoping or limited synoptic water quality studies, or providing technical representation to the NPS requiring water quality expertise.
2023 Technical Assistance Projects
Two-year investigations of water quality to provide a timely assessment of aquatic conditions at selected locations and to evaluate the spatial relationships or contributions to those conditions, and/or to provide baseline data and information where little exists. The studies document status in water quality and may determine if management actions are achieving water quality objectives.
2023 Synoptic Projects
High Resolution CO2 Measurements to Better Understand Visitor Impact on Cave Water Quality
A Nationwide Assessment of Per-and Polyfluoroalkyl substances (PFAS) on National Park Service Lands
Three-year investigations that entail in-depth study of park water quality. Designed to characterize known or suspected water quality problems, these projects also focus on understanding causes of contamination and the implications of water quality impairment to aquatic biota.
2023 Intensive Projects
Identification and Distribution of Toxigenic Benthic Cyanobacteria in Yosemite
