Multiple physical and chemical stressors can simultaneously affect the biological condition of streams. To better understand complex interactions land-use practices, water quality, ecological integrity streams, U.S. Geological Survey National Water Quality Assessment Project is conducting regional-scale assessments stream across United States. In summer 2013, weekly samples were collected from 100 streams in Midwestern Employing watershed theory, we used structural equation modeling (SEM) to represent a general hypothesis for how 16 variables (previously identified be important condition) might inter-related. Again, using SEM, evaluated ability this "stressor network" explain variations multimetrics algal, invertebrate, fish community health, trimming away any environmental not contributing an explanation responses. Seven variables-agricultural urban land use, sand content soils, basin area, percent riparian area as forest, channel erosion, relative bed stability-were found all three-community metrics. The algal invertebrate models included water-chemistry model. Results suggest that Midwest are affected by both agricultural uses natural geologic setting, indicated soils.

Multistressor studies were performed in five regions of the United States to assess role pesticides as stressors affecting invertebrate communities wadable streams. Pesticides and other chemical physical measured 75 99 streams per region for 4 weeks, after which surveyed (435 total sites). sampled weekly filtered water, once bed sediment. The a stressor was assessed by evaluating multiple lines evidence: toxicity predictions based on pesticide concentrations, multivariate models statistical analyses, previously published mesocosm experiments. Toxicity using benchmarks species sensitivity distributions correlations suggested that present at high enough concentrations adversely affect regional scale. Two undirected techniques—boosted regression tree distance-based linear models—identified predictors (respectively) metrics community composition. To put insecticides context with known, influential covariates response, generalized additive used identify individual pesticide(s) important condition each region, accounting natural covariates. Four identified scale: bifenthrin, chlordane, fipronil its degradates, imidacloprid. Fipronil particularly Southeast imidacloprid, chlordane regions. For fipronil, supported experiments demonstrated adverse effects naïve aquatic when dosed under controlled conditions. These evidence do not prove causality—which is challenging field multistressor conditions—but they make strong case within

Elevated nitrogen concentrations in streams and rivers the Chesapeake Bay watershed have adversely affected ecosystem health of bay. Much this is derived as nitrate from groundwater that discharges to base flow. In study, boosted regression trees (BRTs) were used relate flow (n = 156) explanatory variables describing sources, geology, soil catchment characteristics. From these relations, a BRT model was developed predict throughout watershed. The highest associated with intensive agricultural land use, carbonate sparse riparian canopy, which suggested reduced inputs, particularly over terrane, are critical for limiting concentrations. lowest extensive high levels organic carbon soils, suboxic conditions at shallow depths, denitrification subsurface, zone, Nitrate transport aquifers can take decades occur, resulting decades-long lag times between time when land-use activity implemented its effects fully observed streams. Predictive models will help identify portions likely large fractions total stream load pathways significant times.
