Accretion of Nutrients and Sediment by a Constructed Stormwater Treatment Wetland in the Lake Tahoe Basin
Autor: Alan C. Heyvaert, Robert G. Qualls
Publikováno v: JAWRA Journal of the American Water Resources Association. 53:1495-1512
This unique study evaluates the cumulative 16-year lifetime performance of a wetland retention basin designed to treat stormwater runoff. Sediment cores were extracted prior to basin excavation and restoration to evaluate accretion rates and the orig

Anthropogenic and climatic influences on the diatom flora within the Fallen Leaf Lake watershed, Lake Tahoe Basin, California over the last millennium
Autor: Alan C. Heyvaert, Briana E. Johnson, Robert Karlin, Paula J. Noble, Sudeep Chandra
Publikováno v: Journal of Paleolimnology. 59:159-173
This study addresses the effects of climate, land-use, and atmospheric nitrogen (N) deposition on the Fallen Leaf Lake watershed, Lake Tahoe Basin, through diatom and geochemical analyses of sediment cores. Four diatom zones are recognized from a cor

The importance of small urbanized watersheds to pollutant loading in a large oligotrophic subalpine lake of the western USA
Autor: David T. Rios, Alan C. Heyvaert, Sudeep Chandra
Publikováno v: Environmental Monitoring and Assessment. 186:7893-7907
Urban land use has been implicated as a major contributor of nonpoint source pollution in aquatic systems. Through increased nonpoint delivery of pollutants, including constituents found in stormwater, Lake Tahoe is undergoing a marked decline in its

Effects of Backpacker Use, Pack Stock Trail Use, and Pack Stock Grazing on Water-Quality Indicators, Including Nutrients, E. coli, Hormones, and Pharmaceuticals, in Yosemite National Park, USA
Autor: Alan C. Heyvaert, James W. Roche, William A. Battaglin, Harrison Forrester, David W. Clow
Publikováno v: Environmental management. 60(3)
We investigated how visitor-use affects water quality in wilderness in Yosemite National Park. During the summers of 2012-2014, we collected and analyzed surface-water samples for water-quality indicators, including fecal indicator bacteria Escherich

Molybdenum geochemistry in a seasonally dysoxic Mo-limited lacustrine ecosystem
Autor: David P. Waetjen, Jennifer B. Glass, Alan C. Heyvaert, Ariel D. Anbar, Brooke Eustis, Anthony Chappaz, Hilairy E. Hartnett
Publikováno v: Geochimica et Cosmochimica Acta. 114:204-219
Lakes are important for storage of the essential micronutrient molybdenum (Mo) during its transfer from the continents to the oceans, but little is known about the major sources and sinks for Mo in lacustrine ecosystems. We studied Mo cycling in Cast

Nutrient and particle load estimates to Lake Tahoe (CA–NV, USA) for Total Maximum Daily Load establishment
Autor: Daniel Nover, G. B. Sahoo, Alan C. Heyvaert, John E. Reuter, John Riverson, S. G. Schladow
Publikováno v: Science of The Total Environment. 444:579-590
The Lake Tahoe Total Maximum Daily Load (TMDL) requires detailed methodologies to identify sources of flows and pollutants (particles and nutrients) for estimating time-variant loads as input data for the Lake Tahoe clarity model. Based on field data

Water quality response to the Angora Fire, Lake Tahoe, California
Autor: John E. Reuter, Allison A. Oliver, Randy A. Dahlgren, Alan C. Heyvaert
Publikováno v: Biogeochemistry. 111:361-376
The Angora Fire (summer of 2007) was the largest and most severe wildfire in recent history within the Lake Tahoe basin of the Sierra Nevada. To determine the watershed response and to assess the potential for downstream impacts of nutrient and sedim

Stormwater and Fire as Sources of Black Carbon Nanoparticles to Lake Tahoe
Autor: M. Thaw, Brian Fitzgerald, Alan C. Heyvaert, James M. Thomas, M. M. Bisiaux, R. B. Susfalk, Ross Edwards, S. Geoffrey Schladow
Publikováno v: Environmental Science & Technology. 45:2065-2071
Emitted to the atmosphere through fire and fossil fuel combustion, refractory black carbon nanoparticles (rBC) impact human health, climate, and the carbon cycle. Eventually these particles enter aquatic environments, where they may affect the fate o
