Stormwater runoff and associated pollutants from urban areas in the Chesapeake Bay Watershed represent a serious impairment to local streams and downstream ecosystems, despite urbanized land comprising only 7% of the Bay watershed area. Excess nitrogen, phosphorus, and sediment affect local streams in the Bay watershed by causing problems ranging from eutrophication and toxic algal blooms to reduced oxygen levels and loss of biodiversity. Traditional management of urban stormwater has primarily focused on directing runoff away from developed areas as quickly as possible. More recently, stormwater best management practices (BMPs) have been implemented in a low impact development (LID) manner on the landscape to treat stormwater runoff closer to its source.The objective of this research was to use a modeling approach to compare total watershed pollutant removal efficiency (TWPRE) of two watersheds with differing spatial patterns of SW BMP design (traditional and LID), and determine if LID SW BMP design offered an improved water quality benefit.

Assessing coastal wetland vulnerability to sea-level rise along the northern Gulf of Mexico coast: gaps and opportunities for developing a coordinated regional sampling network

The study area included the coasts of all five U.S. states along the northern Gulf of Mexico (i.e., Florida, Alabama, Mississippi, Louisiana, and Texas). We contacted federal, state, and university-affiliated scientists working with SET-MH data within this area to obtain the geographic coordinates and the installation year for each SET-MH station. Please note that while our inventory is extensive and includes most SET-MH stations in the region, our inventory is not fully exhaustive; in other words, it is possible that some stations in the region are not contained within this inventory. The SET-MH stations in our dataset include original SET, deep rod SET (RSET), and shallow RSET benchmarks.

Watershed boundaries for the Puget Sound Stormwater Action Monitoring small stream status and trends project

Stormwater Action Monitoring (SAM) is a collaborative monitoring program between western Washington municipal stormwater permittees, state and federal agencies.  SAM’s role is to use the results of regional monitoring and focused studies to inform policy decisions and identify effective strategies to improve stormwater management in the Puget Sound region.  The SAM program includes status and trends monitoring of water quality, stream biota (macroinvertebrates, algae), and stream habitat to measure whether conditions are getting better or worse and identify patterns in healthy and impaired Puget Lowland streams.
To meet this objective, a framework of fundamental geospatial data was required to develop physical and anthropogenic characteristics of the study region, sampled sites and corresponding watersheds, and riparian zones. This dataset represents the watershed boundaries for the 105 sites sampled for the SAM small stream study, and is one of the four fundamental geospatial data layers that were developed for this study. In addition, watershed boundaries for 16 reference sites in the Puget lowlands sampled by the Washington State Department of Ecology’s Ambient Biological Monitoring program from 2010 to 2015 were included in this analysis to provide a regional context for the SAM study. In total, watershed boundaries for 121 total sites are provided in this data release.

Data from Methane in Aquifers Used for Public Supply in the United States

In 2013 to 2015, 833 public supply wells in 15 Principal aquifers in the United States (U.S.) were sampled to identify which aquifers contained high methane concentrations (&gt;1 mg/L) and determine the geologic, hydrologic, and geochemical conditions associated with high concentrations. This study represents the first national assessment of methane in aquifers used for public supply in the U.S. and, as such, advances the understanding of the occurrence and distribution of methane in groundwater nationally. Methane concentrations &gt;1 and &gt;10 mg/L occurred in 6.7 and 1.1% of the samples, respectively. Most high concentrations occurred in aquifers in the Atlantic and Gulf Coastal Plain regions and upper Midwest. High methane concentrations were most commonly associated with Tertiary and younger aquifer sediments, old groundwater (&gt;60 years), and concentrations of oxygen, nitrate-N, and sulfate &lt;0.5 mg/L. Concentrations of methane were also positively correlated (p&lt;0.05) with dissolved organic carbon (DOC) and ammonium. Case studies in Florida, Texas, and Iowa were used to explore how regional context from this data set could aid our understanding of local occurrences of methane in groundwater. Regional data for methane, Br/Cl ratios, sulfate, and other parameters helped identify mixing processes involving end members such as wastewater effluent-impacted groundwater, saline formation water, and pore water in glacial till that contributed methane to groundwater in some cases and supported methane oxidation in others.

Cytonuclear discordance in the Florida Everglades invasive Burmese python (Python bivittatus) population reveals possible hybridization with the Indian python (P. molurus)

Invasive Burmese pythons (Python bivittatus) have been reproducing in the Florida Everglades since the 1980s. Introduction of the species was either due to unintentional escapes or intentional releases from snakes obtained through the commercial pet trade. Burmese pythons have caused a precipitous decline in small mammal populations in south Florida. To better understand the invasive population, two mitochondrial loci (mtDNA; 1398 bps) were sequenced on 426 snakes and 22 microsatellites were genotyped on 389 snakes. Concatenated cytochrome b and cytochrome oxidase 1 mtDNA sequences produced six haplotypes with a nucleotide and haplotype diversity of π=0.002 and h=0.097, respectively. The dominant haplotype was highly divergent from the second most frequent haplotype (π =0.0388).  The average number of microsatellite alleles and expected heterozygosity were NA = 5.50 and HE = 0.60, respectively. Nuclear Bayesian assignment tests supported two genetically distinct groups and an admixed group. The effective population size was lower than expected for a population of this size (Ne =315.1), but reflective of the overall low genetic diversity.  Patterns for genetic diversity between mtDNA and microsatellites were disparate, indicating nuclear introgression of separate mtDNA stocks due to interbreeding among sympatric populations/stocks of P. bivittatus. Alternatively, hybridization between P. molurus and P. bivittatus may have occurred in native or captive populations.  The introgression may have occurred in the native range, breeding of disparate stocks in the pet trade, or in the invasive habitat. The invasive Florida Burmese python sequences were similar to the published sequences identified as P. bivittatus and P. molurus, however the nuclear diversity was nearly half of that reported in wild populations sampled within the native range.

Arsenic and Iron data (2010-2015) for petroleum plume mass balance, Bemidji MN

Natural attenuation of organic contaminants in groundwater can give rise to a series of complex biogeochemical reactions that release secondary contaminants to groundwater. In a crude oil contaminated aquifer, biodegradation of petroleum hydrocarbons is coupled with the reduction of ferric iron (Fe(III)) hydroxides in aquifer sediments. As a result, naturally occurring arsenic (As), adsorbed to Fe(III) hydroxides in the aquifer sediment, is mobilized from sediment into groundwater. However, Fe(III) in sediment of other zones of the aquifer has the capacity to attenuate dissolved As via re-sorption. To better evaluate how long-term biodegradation coupled with Fe-reduction and As mobilization can redistribute As mass in contaminated aquifer, we quantified mass partitioning of Fe and As in the aquifer based on field observation data. Results show that Fe and As are spatially correlated in both groundwater and aquifer sediments. Mass partitioning calculations demonstrate that 99.9% of Fe and 99.5% of As are associated with aquifer sediment. The sediments act as both sources and sinks for As, depending on the redox conditions in the aquifer. Calculations reveal that at least 78% of the original As mass in sediment near the oil has been mobilized into groundwater over the 35-year lifespan of the plume. However, the calculations also show that only a small percentage of As mass (~0.5%) remains in groundwater, due to resorption onto sediment. At the leading edge of the plume, where groundwater is suboxic, sediments sequester Fe and As, causing As to accumulate to concentrations 5.6 times greater than background concentrations. However, current arsenic sinks can serve as future sources of arsenic as the plume evolves over time. The mass balance approach used in this study can is applicable to As cycling in other aquifers where groundwater As results from biodegradation of an organic carbon point source coupled with Fe reduction.

Conventional PCR results for detecting Tetracapsuloides bryosalmonae in fish tissue and water samples

We developed and validated conventional and quantitative real-time PCR assays for the detection of DNA from the myxozoan parasite Tetracapsuloides bryosalmonae, the causative agent of proliferative kidney disease in fish. Assays were tested on fish tissue and on field-collected water samples to assess diagnostic and environmental DNA capabilities. The specificity, sensitivity, and broad applicability of the present assays surpass previous methods for detecting T. bryosalmonae DNA from fish tissue and water samples.

Nitrogen, Phosphorus, and Suspended-Sediment Loads and Trends Measured at the Chesapeake Bay Nontidal Network Stations: Water Years 1985-2014

Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the Chesapeake Bay Nontidal Network (NTN) stations for the period 1985 through 2014. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach called WRTDS (Weighted Regression on  Time, Discharge, and Season).  The load results represent the total mass of nitrogen, phosphorus, and suspended sediment that was exported from each of the NTN watersheds.  To determine the trend in loads, the annual load results are flow normalized to integrate out the year-to-year variability in river discharge.  The trend in load is derived from the  flow-normalized load timeseries and represents the change in load resulting from changes in sources, delays associated with storage or transport of historical inputs, and (or) implemented management actions.  Four data tables are provided that describe nitrogen, phosphorus, and suspended-sediment conditions across the NTN: (1) Annual Loads, (2) Monthly Loads, (3) Trends in Annual Loads, and (4) Average Yield (mass per unit area).

Borehole Geophysical Data Associated with Uranium Background Concentrations at Homestake Mining Company Superfund Site near Milan, New Mexico, July 2016 through October 2016

The data set contained herein were collected as part of a cooperative U.S. Geological Survey and U.S. Environmental Protection Agency (EPA) project entitled "Field Investigations to Help Support the Assessment of Background Concentrations for Uranium (U) at the Homestake Mining Company, Superfund Site near Milan, New Mexico, July 2016.” The site is underlain by alluvial and several consolidated rock units (Chinle and San Andreas aquifers) that contain in some cases elevated concentrations of U above the EPA MCL (maximum contaminant level). Borehole geophysical data were collected from six alluvial wells at the site. Borehole geophysical logs included: induction, fluid resistivity, natural gamma, spectral gamma, fluid temperature, caliper, casing collar locator, optical televiewer, and electromagnetic flow meter logging (ambient and stressed). Geophysical data collected from these wells were used to evaluate well construction, stratigraphy, distribution of potassium, uranium, and thorium, locations of passive sampler deployment and placement, and inflow and outflow intervals of a well under ambient and pumped conditions.

Sex, length, total mass, fat mass, and specimen condition data for 248 Burmese pythons (Python bivittatus) collected in the Florida Everglades

These data were collected from Burmese pythons removed from the Florida everglades as part of invasive-species management. After euthanasia, we sexed (male or female) and measured the snout-vent length (SVL; cm) and total body mass (g) for each python. We also measured total fat mass (g) by removing all visible fat bodies from the coelomic cavity and weighing this mass. For a subset of specimens, we recorded whether the pythons were put on ice after euthanasia and measured within 24 hours ('fresh') or whether the pythons were frozen after euthanasia, thawed, and then measured ('frozen'). These data were used to validate several body condition indices in Burmese pythons.
