These datasets were created in support of the U.S. Geological Survey's (USGS) Next Generation Water Observing System (NGWOS) for the Delaware River Basin pilot study (Eberts, Wagner, and Woodside, 2019). The NGWOS utilizes real-time data, improved computational capabilities, and new technologies such as unmanned aerial vehicles (UAV) and autonomous underwater vehicles (AUV) to provide information on water quality and/or quantity, in more locations, quickly and efficiently (Eberts, Wagner, and Woodside, 2019). Combined with advanced modeling applications, the NGWOS will be an important tool for water-resource managers and emergency management. In this study, water-quality and bathymetric data were measured with an...

Here we report optical data collected as part of a collaborative study between USGS Pennsylvania Water Science Center, Pennsylvania Department of Environmental Protection and Water Mission Area Proxies Project. The optical measurements reported here were collected to aide in the characterization of water sources and mixtures and establish proxies (surrogates) for per- and poly-fluorinated alkyl substances within the Neshaminy Creek basin. Data are compiled into three tables: 1) full fluorescence spectra in vectorized format, 2) full absorbance spectra, and 3) summary file of commonly extracted optical indicators and field-based sensor arrays.

This data set contains U.S. Geological Survey (USGS) streamgage matching results in tabular format for water-quality sites retrieved from the Water Quality Portal for the Delaware River Basin. The table contains a list of water-quality sites joined to USGS streamgages where the water-quality site and USGS streamgage are located on the same stream, as represented by the National Hydrography Dataset Plus (NHDPlus) "LevelPathID" attribute. The file represents a one-to-many relationship: each water-quality site, as represented by the unique identifier, "MonitoringLocationIdentifier", is joined to anywhere from zero streamgages (not on same stream as any gage; the gage info columns are NA) to one or more streamgages...

Five discrete groundwater seepage measurements were collected to make a direct measurement of the flux of water across the sediment-water interface. Change in volume/time is the volumetric rate of flow. The volumetric rate of flow was used to calculate flux velocity (distance/time), by dividing the specific area of the seepage meter (2.70-square-feet). The change in volume over the time the seepage test was conducted is the volumetric flow rate of ground water seepage. Flux velocity could be multiplied by the study area to acquire a shallow groundwater flux.

Jointly managed by multiple states and the federal government, there are many ongoing efforts to characterize and understand water quality in the Delaware River Basin (DRB). Many State, Federal and non-profit organizations have collected surface-water-quality samples across the DRB for decades and many of these data are available through the National Water Quality Monitoring Council's Water Quality Portal (WQP). For this data release, WQP data in the DRB were harmonized, meaning that they were processed to create a clean and readily usable dataset. The harmonization process included the synthesis of parameter names and fractions, the condensation of remarks and other data qualifiers, the resolution of duplicate...
The USGS Pennsylvania Water Science Center (USGS PAWSC) in cooperation with the Pennsylvania Department of Environmental Protection (PADEP) has assembled this data release in support of ongoing USGS and PADEP evaluations related to the occurrence and distribution of Per-and Polyfluorinated Alkyl Substances (PFAS) within Pennsylvania surface water. The data is of four general types: Discrete sample (one moment in time) PFAS concentration data from untreated surface water (raw stream and raw lake water) intended to describe environmental occurrence and distribution of PFAS, not to assess risk in drinking water; Quality-control (QC) PFAS data from samples intended to evaluate the effectiveness and reliability of...

The U.S. Geological Survey (USGS), as part of the Next Generation Water Observing System (NGWOS) has collected discrete stream samples for analysis of suspended-sediment concentrations at eight real-time streamflow and water-quality monitoring (turbidity and suspended sediment) stations located in Pennsylvania, New Jersey, and New York in the Delaware River Basin. Data were collected from 2019-2022 at these stations for the application of predicting suspended-sediment concentrations using real-time continuous turbidity, suspended sediment from an uncalibrated sensor, and streamflow data. Regression equations were developed by relating discrete-sample suspended sediment and continuous turbidity, suspended sediment...

Large lakes provide a variety of ecological services to surrounding cities and communities. Many of these services are supported by ecological processes that are threatened by the increasing prevalence of cyanobacterial blooms which occur as aquatic ecosystems experience cultural eutrophication. Over the past 10 years, Lake Erie experienced cyanobacterial blooms of increasing severity and frequency, which have resulted in impaired drinking water for the surrounding communities. Cyanobacterial blooms may impact ecological processes that support other services, but many of these impacts have not been documented. Secondary production (production of primary consumers) is an important process that supports economically...

The U.S. Geological Survey (USGS), in cooperation with the York County Planning Commission and York County Conservation District, has collected discrete stream samples for analysis of suspended-sediment, total nitrogen, and total phosphorus concentrations at six real-time streamflow and water-quality monitoring (turbidity, nitrate, and specific conductance) stations located in York County, Pennsylvania. Data were collected from 2019-2023 at these stations for the application of predicting suspended-sediment, total nitrogen, and total phosphorus concentrations using real-time continuous turbidity, nitrate, specific conductance, and streamflow. Regression equations were developed by relating discrete-sample suspended...
