Organic chemicals have been detected at trace concentrations in the freshwater environment for decades. Though the term trace pollutant indicates low concentrations normally in the nanogram or microgram per liter range, many of these pollutants can exceed an acceptable daily intake (ADI) for humans. Trace pollutants referred to as emerging contaminants(More)
The purpose of this paper is to present biomass and nutrient uptake data from Neochloris oleoabundans production in an open trough system. The growth medium used was BG11, temperature ranged from 16.7 °C to 25.3 °C, and pH ranged from 5.52 to 9.94 because the customary pH increase during algal biomass production was moderated by incoming CO(2) gas streams(More)
A method to predict aquifer vulnerability to pesticide contamination at the subregional scale was developed. The assessment method was designed to incorporate relevant hydrologic and pesticide-transport information and to use generally available data. The method assumes steady-state advection of pesticides in the vadose zone, including sorption and(More)
A common goal of water and energy management is to maximize the supply of one while minimizing the use of the other, so it is important to understand the relationship between water use and energy production. A larger proportion of horizontal wells and an increasing number of hydraulically fractured well bores are being completed in the United States, and(More)
Open-File Reports are used for the dissemination of information that fills a public need and are intended to make the results of research available at the earliest possible date. Because of their nature and possibility of being superseded, an Open-File Report is intended as a preliminary report not as a final publication. Analyses presented in this article(More)
This study was designed to examine carbon utilization within scalable microalgae production systems. Neochloris oleoabundans was produced in replicated troughs containing BG11 nutrient formulation. Atmospheric CO(2) was supplemented with ∼5% CO(2) or with NaHCO(3), and the pH of troughs receiving NaHCO(3) was adjusted with HCl or H(3)PO(4). Peak biomass(More)
Nature of the Course Content: Geographic Information Systems (GIS) for Water Resources will focus on the use of GIS for analysis of geographically referenced hydrologic data. Objectives/Goals of the Course: • Gain proficiency in the use of relational databases and hydrologic data models. • Learn to use GIS tools for analyzing surface water and groundwater(More)
Nutrient loading to surface water systems has traditionally been associated with agricultural sources. Sources such as on-site wastewater systems (OWS) may be of concern especially in rural, nonagricultural watersheds. The impact of various point and nonpoint sources including OWS in Turkey Creek Watershed was evaluated using the Watershed Analysis Risk(More)
