title: Rapid production of highly oxidized molecules in isoprene aerosol via peroxy and alkoxy radical isomerization pathways in low and high NOx environments: Combined laboratory, computational and field studies

description: Recently, we identified seven novel hydroxy-carboxylic acids resulting from gas-phase reactions of isoprene in the presence of nitrogen oxides (NOx), ozone (O3), and/or hydroxyl radicals (OH). In the present study, we provide evidence that hydroxy-carboxylic acids, namely methyltartaric acids (MTA) are: (1) reliable isoprene tracers, (2) likely produced via rapid peroxy radical hydrogen atom(H) shift reactions (autoxidation mechanism) and analogous alkoxy radical H shifts in low and high NOx environments respectively and (3) representative of aged ambient aerosol in the low NOx regime. Firstly, MTA are reliable tracers of isoprene aerosol because they have been identified in numerous chamber experiments involving isoprene conducted under a wide range of conditions and are absent in the oxidation of mono- and sesquiterpenes. They are also present in numerous samples of ambient aerosol collected during the past 20 years at several locations in the U.S. and Europe. Furthermore, MTA concentrations measured during a year-long field study in Research Triangle Park (RTP), NC in 2003 show a seasonal trend consistent with isoprene emissions and photochemical activity. Secondly, an analysis of chemical ionization mass spectrometer (CIMS) data of several chamber experiments in low and high NOx environments show that highly oxidized molecules (HOMs) derived from isoprene that lead to MTAs may be produced rapidly and considered as early generation isoprene oxidation products in the gas phase. Density functional theory calculations show that rapid intramolecular H shifts involving peroxy and alkoxy radicals possess low barriers for methyl-hydroxy-butenals (MHBs) that may represent precursors for MTA. From these results, a viable rapid H shift mechanism is proposed to occur that produces isoprene derived HOMs like MTA. Finally, an analysis of the mechanism shows that autoxidation-like pathways in low and high NOx may produce HOMs in a few OH oxidation steps like commonly detected methyl tetrol (MT) isoprene tracers. The ratio of MTA/MT in isoprene aerosol is also shown to be significantly greater in field versus chamber samples indicating the importance of such pathways in the atmosphere even for smaller hydrocarbons like isoprene.

title: PiSCES Dataset

description: The Piscine Stream Community Estimation System (PiSCES) provides users with a hypothesized fish community for any stream reach in the conterminous United States using information obtained from Nature Serve, the US Geological Survey (USGS), StreamCat, and the Peterson Field Guide to Freshwater Fishes of North America for over 1000 native and non-native freshwater fish species. PiSCES can filter HUC8-based fish assemblages based on species-specific occurrence models; create a community abundance/biomass distribution by relating relative abundance to mean body weight of each species; and allow users to query its database to see ancillary characteristics of each species (e.g., habitat preferences and maximum size). Future efforts will aim to improve the accuracy of the species distribution database and refine/augment increase the occurrence models. The PiSCES tool is accessible at the EPA's Quantitative Environmental Domain (QED) website at https://qed.epacdx.net/pisces/

title: US EPA EnviroAtlas Meter-Scale Urban Land Cover (MULC) Data Characteristics

description: Meter-scale Urban Land Cover (MULC), a unique, high resolution (one meter2 per pixel) land cover dataset, has been developed for 30 US communities for the United States Environmental Protection Agency (US EPA) EnviroAtlas. MULC data categorize the landscape into these land cover classes: impervious surface, tree, grass-herbaceous, shrub, soil-barren, water, wetland and agriculture. MULC data are used to calculate approximately 100 EnviroAtlas metrics that serve as indicators of nature’s benefits (ecosystem goods and services). MULC, a dataset for which development is ongoing, is produced by multiple classification methods using aerial photo and LiDAR datasets. The mean overall fuzzy accuracy across the EnviroAtlas communities is 88% and mean Kappa coefficient is 0.84. MULC is available in EnviroAtlas via web browser, web map service (WMS) in the user’s geographic information system (GIS), and as downloadable data at EPA Environmental Data Gateway. Fact Sheets and metadata for each MULC Community are available through EnviroAtlas. Some MULC applications include mapping green and grey infrastructure, connecting land cover with socioeconomic/demographic variables, street tree planting, urban heat island analysis, mosquito habitat risk mapping and bikeway planning. This article provides practical guidance for using MULC effectively and developing similar high resolution (HR) land cover data.

title: Comparison of Soil Loss Estimates Derived using the Revised Universal Soil Loss Equation with those Derived by the Iowa State University's Daily Erosion Project for 12-digit HUCs.

description: This data contains a comparison between the soil loss values we calculated using RUSLE and those produced by the Iowa State University's Daily Erosion Project (DEP). The comparison is done for almost 5,000 12-digit HUC's in Iowa, and parts of  Minnesota, Nebraska, Kansas, and Missouri. The DEP uses the Water Erosion Prediction Project (WEPP) hillslope model with high temporal resolution, Next-Generation Weather 200 RADAR (NEXRAD) precipitation, and crop specific parameters such as C and P factors obtained from the confidential NRI database 
The comparison between RUSLE and DEP was made for HUC-12s with greater than 75% agricultural land cover. This threshold was used because DEP only models  agricultural erosion, while our RUSLE-derived HUC-12 estimates include all land cover types. This data set corresponds to Fig 2 in the manuscript.

title: Supporting Clean-Up of Contaminated Sites with Decision Analysis: A Case Study on Prioritization of Remediation Alternatives in Superfund 

description: The summary from the detailed analysis of the case study in EPA (1988b) is provided in Table 3 of the manuscript, and was used as the data source for the two datasets used in this study. These include a flat and hierarchical structure of the five balancing criteria, shown in Table 4 and Table 5, respectively. Table 4 provides a comprehensive score for each balancing criterion, similar to the summary tables presented in the FS of Superfund sites (e.g., (EPA 2016b, AECOM 2019)). Table 5 uses the same information in Table 3, but in this case, each piece of information is used to define multiple sub-criteria for each balancing criterion, except the cost one. This leads to a much more elaborate information table with the four remaining balancing criteria, now characterized by 13 sub-criteria. 

It is important to note that the scoring provided in Table 4 and Table 5, with the exception of the cost (c_5), were derived from the author’s interpretation of the descriptive language of the detailed analysis in for the hypothetical case study in presented in Table A-7 in Appendix A of the guidance document of EPA (1988b). It should be noted that the analysis of the three remedy alternatives presented in this hypothetical case study is governed by site-specific characteristics and may not represent potential performance of these remediation alternatives for other sites .  The intent of this exercise is to illustrate the flexibility and adaptability of the MCDA process to address both the main, overarching criteria, as well as sub-criteria that may have specific importance in the decision process for a particular site.  Ultimately, the sub-criteria can be adapted to address specific stakeholder perspectives or technical factors that may be linked to properties unique to the contaminant or physical characteristics of the site.

title: Salmonella Mutagenicity Data from Wildfire Firefighter's Urine

description: The dataset is the raw and partially analyzed urinary mutagenicity data, which were generated by US EPA scientists at the US EPA/RTP.  The data consist of the number of mutant colonies (revertants) per petri plate at each dose of the organic extract of the urine.  These are accompanied by the positive and negative controls.  In addition, the data from each experiment have been partially analyzed by performing a linear regression of the data to generate a slope value (revertants/ml-equivalents of urine) as well as an r-squared value, which is a measure of how linear the line is (i.e., how close to a straight line the data are).

title: Use of Threshold of Toxicological Concern (TTC) with High Throughput Exposure Predictions (HTE) as a Risk-Based Screening Approach to Prioritize More Than Seven Thousand Chemicals

description: The dataset that was evaluated in this approach was taken from Wambaugh et al [29] who filtered the Tox21 library to reflect substances with similar uses to those in NHANES.

The zip file contains the supplementary information being provided for the re-analysis performed in this dataset. 
There was no specific code as such developed for the analysis aside from using KNIME to help combine different outputs from different tools including Leadscope in order to arrive at the counts reflected in Table 2 of the manuscript. 
Instead of this very laborious approach, we re-did the analysis using Toxtree alone and streamlined the processing of the outcomes with R. This is documented in the supplementary information file.

title: Omaha Property Values and GI

description: In Omaha, NE, more than 25 GI projects have been completed to date, with several featuring GI practices in public parks. Using a repeat sales model , we examined the effect of GI on the value of nearby single-family homes, based on housing sales and characteristic data from 2000 to 2018. We evaluated the sales price for homes using a buffer zone of 0-0.5km, and three additional models: homes within 0-0.25km, 0.25-0.5km, and greater than 0.5km from parks where GI was installed for 25,472 sale pairs. In addition to the repeat sales model, we performed a hot spot analysis on several demographic characteristics to capture systematic differences at a smaller spatial scale and over a longer time period than the repeat sales model could capture. We used US Census data on race and household income to examine changing patterns over time and space, and a spatial lag Maximum Likelihood Estimation model to determine if the location of GI correlated with either of these demographics.

title: Performance and Characterization Data of a Degassed Anaerobic Membrane Biofilm Reactor Version 1

description: The goal of this study was to develop and evaluate an anerobic treatment system designed to overcome limitations associated with mass transfer resistances caused by fouling of dissolved methane recovery membranes in anaerobic membrane bioreactors. To this end, a novel attached growth anaerobic treatment system designed to emphasize the growth of the attached biofilm, rather than its removal, to optimize reactor performance. To accomplish this, a methane producing biofilm was developed on the shell side surface of submerged hollow fiber membranes, which allowed for immediate recovery of methane as it was produced, negating the liquid boundary layer and mass transfer fouling resistances.  Impacts of membrane surface treatment on biofilm development were investigated as well. Details of the performance and characterization of the anaerobic treatment system can be found in DAMBR_Performance_and_Characterization_Data.xlsx

title: Part III. Scale-up Testing and Assessment of Selected Potential Operational Issues

description: This study evaluated reuse of lime softening sludge, generated from drinking water treatment utilities, as an environmental sorbent for capturing SO2 and heavy metals in wet scrubbers of coal-fired power plants. Specifically, Part III evaluated viscosity and metal corrosion as practical issues in the transition from limestone to lime sludge at power plants. Results of Marsh funnel viscosity experiments conducted at different solids contents and temperatures indicated the limestone and lime sludge slurries and their gypsum counterparts had similar flow characteristics. Carbon-steel, stainless-steel, and Hastelloy coupons were tested for corrosion by lime sludge and limestone slurries. Both stainless steel and Hastelloy were resistive to corrosion in slurries made from lime sludge or limestone samples or their gypsum counterparts. A considerable but similar amount of corrosion was observed for carbon-steel coupons exposed to lime sludge and limestone slurries. Adding 5000 ppm of Cl to slurries considerably increased the corrosion rate of carbon steel.
