“…Plots depicting those values were compared to USEPA nutrient reference criteria and that proposed by Herlihy et al . () for USEPA ecoregions VII (SLBE) and VIII (ISRO, VOYA, and PIRO) using SigmaPlot 11.0. In brief, for the proposed criteria Herlihy et al .…”

“…In an effort to further refine the USEPA nutrient reference criteria, Herlihy et al . () analyzed nutrient data from the USEPA's National Lakes Assessment (USEPA, ), a probabilistic survey of 1,028 lakes across the United States (U.S.) to quantify and contrast different methods of setting nutrient criteria. Four methods (25th percentile of population, 75th percentile of least‐disturbed reference sites, diatom‐based paleolimnological reconstruction, and stressor modeling) were used to calculate potential alternative reference criteria for TP, TN, and Chl‐ a , which were also compared with criterion values reported by USEPA based on the 25th percentile of found data in each nutrient ecoregion.…”

“…The potential nutrient reference criteria proposed by Herlihy et al . () for the same USEPA national nutrient ecoregions represent a new set of assessment points (Bennetts et al ., ), below which a lake's nutrient status could be considered to represent a reference or background condition and thus be protective of aquatic life and recreational uses.…”

Understanding what constitutes a reference (background) nutrient condition for lakes is important for National Park Service managers responsible for preserving and protecting aquatic resources. For this study we characterize water quality conditions in 29 lakes across four national parks, and compare their nutrient status to U.S. Environmental Protection Agency (USEPA) nutrient reference criteria and alternative criteria recently proposed by others. Where appropriate we also compare the nutrient status of these 29 lakes to state or tribal nutrient reference criteria or standards. For lakes that exceed reference criteria we investigate physical and chemical patterns, and for a subset of lakes compare modern nutrient conditions to paleolimnological (i.e., diatom‐inferred [DI]) nutrient reconstructions. Many lakes exceeded USEPA nutrient reference criteria, but met alternative less restrictive criteria. Modern nutrient conditions were also largely consistent with DI historic (pre‐1900) nutrient conditions. Lakes exceeding alternative nutrient criteria and with elevated nutrient levels relative to DI historic conditions were mostly small, shallow, and dystrophic; continued attention to their nutrient dynamics and biological response is warranted. Coupling modern and paleolimnological data offer an innovative and scientifically defensible approach to understand long‐term nutrient trends and provide greater context for comparison with reference conditions.

“…Thresholds were values that would unlikely be found in least-disturbed lakes within each region, and the threshold values varied by lake type to account for regional variations in water chemistry and littoral-riparian anthropogenic activities (Herlihy et al 2013). A lake was considered leastdisturbed if it passed the screening test for all parameters; 160 potential least-disturbed reference lakes were identified.…”

“…We hope to refine the thresholds as more data are gathered through future NWCA surveys. The NWCA is conducted every five years, and, over time, we plan to use the heavy metal concentrations measured in least disturbed sites (e.g., Herlihy and Sifneos 2008; Herlihy et al 2013) to revise our thresholds. Depending on the number of least disturbed sites sampled, we may be able to revise the thresholds based on region, parent material, or other wetland characteristics.…”

Soil concentrations of 12 heavy metals that have been linked to various anthropogenic activities were measured in samples collected from the uppermost horizon in approximately 1000 wetlands across the conterminous US as part of the 2011 National Wetland Condition Assessment (NWCA). The heavy metals were silver (Ag), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb), antimony (Sb), tin (Sn), vanadium (V), tungsten (W), and zinc (Zn). Using thresholds to distinguish natural background concentrations from human-mediated additions, we evaluated wetland soil heavy metal concentrations in the conterminous US and four regions using a Heavy Metal Index (HMI) that reflects human-mediated heavy metal loads based on the number of elements above expected background concentration. We also examined the individual elements to detect concentrations of heavy metals above expected background that frequently occur in wetland soils. Our data show that wetland soils of the conterminous US typically have low heavy metal loads, and that most of the measured elements occur nationally in concentrations below thresholds that relate to anthropogenic activities. However, we found that soil lead is more common in wetland soils than other measured elements, occurring nationally in 11.3% of the wetland area in concentrations above expected natural background (> 35 ppm). Our data show positive relationships between soil lead concentration and four individual landscape metrics: road density, percent impervious surface, housing unit density, and population density in a 1-km radius buffer area surrounding a site. These relationships, while evident on a national level, are strongest in the eastern US, where the highest road densities and greatest population densities occur. Because lead can be strongly bound to wetland soils in particular, maintenance of the good condition of our nation’s wetlands is likely to minimize risk of lead mobilization.
