We had the pleasure of presenting the results of our nutrient impairment study of Lake Cypress Springs at the Texas Commission on Environmental Quality Surface Water Quality Monitoring workshop. This was the very first nutrient impairment study in Texas. The results suggest that the high pH impairment in the reservoir is driven by primary productivity. Although chlorophyll-a and pH were not strongly correlated, this may be due to sampling at 0.3-meter below the surface rather than using depth integrated sampling methods. However, using dissolved oxygen percent saturation as a surrogate for algae, this parameter strongly correlated with pH throughout the diel studies. Some of those correlations were as high as 1.00 and averaged around 0.9 at all stations. The results of this study along with two other special studies are available at: https://lnkd.in/ggZUwGj7 We also assisted with training TCEQ and Clean Rivers Program partners on measuring flow using the SonTek - a Xylem Brand FlowTracker 2 ADV.

Phosphorus (P) is a fundamental element for plant and animal growth; however, an excessive amount of phosphorus can cause a threat to ecological environmental safety and human health. Therefore, this study aims to synthesize an adsorbent based on calcium silicate hydrates using mixture of Polonite and calcium oxide and to determine its adsorption capacity for phosphorus ions.

We recently published a paper in ES&T letters on the aqueous solubility, critical micelle concentration (CMC) and acid dissociation constant (pKa) for two forms of PFOA. https://lnkd.in/er2TtuMR Here, we show that PFOA (1) is unlikely to form micelles in solution at environmental relevant concentrations, (2) reported CMC values may actually correspond to the solubility limit rather than micelle formation, and (3) aqueous solubility values can vary by orders of magnitude depending upon the counterion species (e.g., acid versus ammonium form) and solution properties (e.g., ionic strength). I have been trying to make the point for several years that PFAS do not behave like traditional hydrocarbon-based surfactants; in comparison PFAS exhibit much lower tendencies to accumulate at the air-water interface or form micelles in aqueous solution. The bottom line is: be very careful when citing or using CMC and solubility values reported for PFAS in the literature! I also want to acknowledge the dedicated work of Craig Klevan, Seth Caines, Andre Gomes who conducted the experiments, analyzed the data, helped to prepare and revise the manuscript. This work was funded by SERDP under project ER21-3540, “Polymer Addition for Improved Removal of Short-Chain PFAS by Dissolved Air Flotation”.
