Nutrient pollution caused by excess nitrogen and phosphorus in the water is a costly and challenging environmental problem with widespread negative health and ecological effects. During Phase I XploSafe successfully confirmed the technical feasibility of using its proprietary low-cost biodegradable sorbents to passively adsorb target nutrient ions (ammonium, nitrate, urea, and phosphate) from prim ...

Epoxy resins are typically created using bisphenol A (BPA), an endocrine disrupting chemical. In addition, over 90% of plastics are derived from virgin fossil feedstocks, equivalent to ~ 6% of global oil consumption. This project proposes to develop an innovative bio-epoxy resin based on the fatty acids of hempseed oil. This approach is to dismantle (by hydrolysis) the triglyceride structure and r ...

As recent crises in Flint, Michigan and Washington D.C. have demonstrated, elevated lead levels (ELL’s) can very suddenly and unexpectedly be introduced to water supplies through seemingly unrelated water system alterations. Ingestion of even trace amounts of lead can have detrimental permanent health effects, especially in children; the public is rightly concerned about lead content in the wate ...

The use of enzyme-linked immunosorbent assay (ELISA) to detect contaminants such as solvents, fuels, and pesticides in soil and water samples is now well established. Although ELISA and related methods can facilitate analysis of samples, several washing and separation steps are involved that require 30 to 120 minutes per sample to reach equilibrium. Recently, near infrared fluorescence immunoassa ...

SOIL WASHING OR FLUSHING HAS BEEN SHOWN TO BE AN EFFECTIVE METHOD FOR REMOVING HEAVY METALS FROM METAL-CONTAMINATED SOILS AT SUPERFUND SITES. SANDY SOILS CAN OFTEN BE WASHED WITH WATER TO MOBILIZE METAL IONS IN AN AQUEOUS PHASE, BUT FOR CLAY SOILS OR SOILS WHICH CONTAIN INSOLUBLE METAL COMPOUNDS, E.G., LEAD SULFATE, OTHER ADDITIVES SUCH AS CHELATING AGENTS (EDTA) ARE USED TO EFFECT TRANSFER OF MET ...

THE PROPOSED RESEARCH WILL DEVELOP AN IN SITU PROCESS WHICH WILL ENHANCE THE RATE AND EFFICIENCY ASSOCIATED WITH THE BIODEGRADATION OF HYDROPHOBIC ORGANIC CHEMICALS AT MILITARY INSTALLATIONS AND SUPERFUND SITES. RESEARCH ACTIVITIES WILLFOCUS ON IDENTIFICATION OF CHEMICAL OR BIOLOGICAL EMULSIFIERS (SURFACTANTS) WHICH WILL ENHANCE THE BIO-AVAILABILITY OF SUCH PETROGENIC WASTE AS CREOSOTE, COAL TARS, ...

This Phase I project involves the development of a portable system for the analysis of trace metals in aqueous solutions based on an innovative disposable multi-element nanoband electrode sensor. The system will be capable of real-time detection of a variety of heavy metals in aqueous solutions, including Zn, Cd, Pb, Cr, Cu, and Hg with a 100 ppb detection limit. The system also will be capable ...
