Summary: Microbial contamination of private well systems, especially in flood-impacted areas, is a significant drinking water concern. A sampling campaign after Hurricane Harvey found high concentrations of Escherichia coli in private wells, posing a risk of infection through drinking water and indirect ingestion exposure. Norovirus and Cryptosporidium were identified as the greatest health risks, with exposure pathways including bathing, showering, and food/dish washing. Conducting post-flood microbial risk assessments of private wells in coastal communities is crucial for providing scientifically supported guidance on safe well water practices where water quality is unknown.

Summary: Drinking-water quality, specifically the presence of per- and poly-fluoroalkyl substances (PFAS), is a rising concern in the United States. This study conducted a national reconnaissance to compare PFAS exposures in unregulated private-well tapwater and regulated public-supply tapwater. The results showed that PFAS profiles and median cumulative concentrations were similar between private wells and public-supply tapwater. The study highlights the need for further assessments of PFAS health risks and the importance of considering co-occurring contaminants, particularly in unmonitored private wells.

Summary: The study revealed that cocrystallization of iodine(i)-based perfluoroarenes with palladium acetate cluster resulted in significant noncovalent interactions, as confirmed by single-crystal X-ray diffractometry. In the structures, aromatic rings were coupled with the cluster through lone pair-pi-(Ar-F)-hole interactions, while iodine-containing arenes were engaged in halogen bonding with carboxylate O centers. The electron-rich PdO4 plane behaved as a nucleophile providing oxygen lone pairs, complementing the pi-acidic surface of the arenes in circular stacking.

Summary: The study showed that soil microbial composition remains stable over time and years, but varies significantly with topographic location, influenced by factors such as moisture, soil organic carbon, and pH. While microbial taxa often correlate with biogeochemical processes, there is a lack of ecological coherence among close relatives. Dominant phyla are consistent across the gradient, but specific members exhibit tradeoffs among locations, indicating a complex relationship between microbial composition and biogeochemical functions.

Summary: The study compares the contributions of different reuse waters (wastewater effluent, urban stormwater, and agricultural runoff) to surface water contamination, revealing substantial organic-chemical contributions from each source. Episodic storm-event organic concentrations and loads from urban stormwater are comparable to and sometimes exceed those of daily wastewater effluent discharges. The study also assesses the impact of wastewater-effluent irrigation on organic-chemical concentrations in rain-induced agricultural runoff and harvested feedstock, finding minimal differences except for two specific organic substances in effluent-irrigated corn.

Summary: The open waters of large lakes can sometimes become depleted in important metals, causing growth limitation or metabolic function limitation in phytoplankton communities. Metal limitation has been observed in isolated waters with low metal supply relative to demand. It is possible that metal limitation could occur within algal blooms due to high demand and low availability of preferred forms of N and P. Laboratory incubation experiments on naturally occurring phytoplankton communities supported the hypothesis of metal limitation occurring in blooms, as low concentrations of metals and labile nutrients were often present. Metal amendments alone did not stimulate growth, but amendments of inorganic N and P resulted in increased chlorophyll. The study suggests that metal limitation may have important implications for phytoplankton communities in eutrophic nearshore areas.

Summary: A comprehensive study of stormwater runoff events at 21 sites across the United States measured 438 organic and 62 inorganic chemicals, revealing localized contamination with potential adverse effects on aquatic health. By assessing cumulative ratios of exposure-activity cutoffs and cumulative toxicity quotients, the study found moderate to high risks for acute adverse effects on aquatic organisms across multiple trophic levels near stormwater discharge points. However, these results are likely significant underestimations of actual risk due to the limited number of compounds analyzed compared to those in commercial use and potential metabolites.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.
