Nigel William Trevelyan Quinn is a water resources engineer, earth scientist and academic who is most known for introducing the concept of real-time water quality management in the 1990s. He has been a Research Group Leader of the HydroEcological Engineering Advanced Decision Support group during his career at Berkeley National Laboratory and has held academic appointments at the University of California, Merced, University of California, Berkeley and California State University, Fresno. He has had a 38-year association with the US Bureau of Reclamation Divisions of Planning and Resource Management that is ongoing. [1]
Quinn was born on December 28, 1955. He attended Milton and Churchill Schools in Zimbabwe. Subsequently, he worked for 11 months as a research technician with the Department of Conservation and Extension in Harare, Zimbabwe, developing and field-testing a tractor-mounted pyrethrum harvester and working in the laboratory on a rapid method for sediment estimation from soil erosion research plots, which was published in the Rhodesian Journal of Agricultural Research. [2]
Quinn graduated with a BSc (Hons) in Agricultural/Irrigation Engineering from Cranfield University in 1977, performing research on the mechanics of footpath erosion, which was later published in the Journal of Environmental Management with co-authors Roy Morgan and Alan Smith. [3] After graduation, he worked as an Irrigation Engineer for Farrow Irrigation, a subsidiary of the Tate and Lyle Corporation. In 1978, he accepted a teaching and research appointment at Iowa State University in the US, later joining the faculty as an Instructor. He graduated with an MS in Agricultural and Civil Engineering, having researched intercepted rainfall throughfall erosivity under various crop canopy architectures, suggesting the inclusion of a canopy subfactor in the Universal Soil Loss Equation; this research was published in the Journal of Agricultural Engineering in 1981. [4] In 1981, he enrolled in a PhD program at Cornell University, serving as a General Electric Fellow with the Department of Civil and Environmental Engineering, and received a PhD in Water Resources Systems Engineering in 1987 under the mentorship of Walter Lynn. He conducted research on a systems approach to selenium drainage management in the San Joaquin Valley of California. [5]
In 1990, he was recruited by the Lawrence Berkeley National Laboratory and Sally Benson, who was leading her own research program on surface and groundwater selenium containment at the Kesterson Reservoir. The Rainbow Report, to which he contributed, provided a long-term solution roadmap for selenium contamination in the San Joaquin Valley, sparking a 38-year scientific research endeavor in this field. Success on an EPA-STAR grant led to his work on climate change impacts, integrating hydrologic, water quality, and economic models, resulting in several publications and an associate faculty position at UC Berkeley. In 2000, he founded the HydroEcological Engineering Advanced Decision Support Group (HEADS) [6] and absorbed emeritus Professor Bill Oswald's research group, focusing on algae-based cultivation and bioremediation amid growing interest in algae biofuels. [7] His technoeconomic assessment of algae biofuel potential, funded by the Energy Biosciences Institute at UC Berkeley, has been highly cited and contributed to Tryg Lundquist's prominence in algae biofuel technology. [8]
After the SJVDP in 1990, Quinn formed a long-term association with Alex Hildebrand (1913–2012), a farmer and CALFED Bay-Delta Advisory Committee governor appointee, sharing ideas on the concept of real-time water quality management, primarily salinity, in the San Joaquin River. [9] He became an advocate and technical proponent of this concept, securing initial grant funding to explore it with the Department of Water Resources, Regional Water Quality Control Board, US Bureau of Reclamation, and US Geological Survey. The real-time water quality management concept was embraced by major state and federal water agencies, endorsed through California state legislation, and enshrined in the San Joaquin Basin Water Quality Control Plan. [10] This advocacy and development resulted in over 30 research publications and book chapters. His early adoption of sensor networks and web-based information dissemination was followed by several water districts and agencies, particularly the Grassland Water District. [11] [12] The WARMF salinity forecasting model originated from his and his colleagues' decision to promote a watershed approach to salinity forecasting, incorporating continuous flow and salinity data into real-time forecasting, enhancing the acceptance of WARMF and similar decision support tools. [13]
Quinn has been a lifelong equestrian and polo player. He was affiliated with the Los Altos Hounds hunt, and co-managed the Wine County Polo Club for 3 years between 2014 and 2017. [14] Additionally, he has been a member of the US Polo Association for over 30 years and a member of the Yolo Polo Club, Sutter Buttes Polo Club, Wine Country Polo Club, Cerro Pampa Polo Club and the Tierra Tropical Polo Club in San Pancho, Mexico. [15] He has been a member of the Manorial Society of Great Britain and acquired the ancient feudal title of Lord of the Manor of Hurstpierpoint in West Sussex, England. [16]
Hydrology is the scientific study of the movement, distribution, and management of water on Earth and other planets, including the water cycle, water resources, and drainage basin sustainability. A practitioner of hydrology is called a hydrologist. Hydrologists are scientists studying earth or environmental science, civil or environmental engineering, and physical geography. Using various analytical methods and scientific techniques, they collect and analyze data to help solve water related problems such as environmental preservation, natural disasters, and water management.
Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, and animals. In accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, wind (aeolian) erosion, zoogenic erosion and anthropogenic erosion such as tillage erosion. Soil erosion may be a slow process that continues relatively unnoticed, or it may occur at an alarming rate causing a serious loss of topsoil. The loss of soil from farmland may be reflected in reduced crop production potential, lower surface water quality and damaged drainage networks. Soil erosion could also cause sinkholes.
Stormwater, also written storm water, is water that originates from precipitation (storm), including heavy rain and meltwater from hail and snow. Stormwater can soak into the soil (infiltrate) and become groundwater, be stored on depressed land surface in ponds and puddles, evaporate back into the atmosphere, or contribute to surface runoff. Most runoff is conveyed directly as surface water to nearby streams, rivers or other large water bodies without treatment.
A renewable resource is a natural resource which will replenish to replace the portion depleted by usage and consumption, either through natural reproduction or other recurring processes in a finite amount of time in a human time scale. When the recovery rate of resources is unlikely to ever exceed a human time scale, these are called perpetual resources. Renewable resources are a part of Earth's natural environment and the largest components of its ecosphere. A positive life-cycle assessment is a key indicator of a resource's sustainability.
A gully is a landform created by running water, mass movement, or commonly a combination of both eroding sharply into soil or other relatively erodible material, typically on a hillside or in river floodplains or terraces.
The Gunnison River is located in western Colorado, United States and is one of the largest tributaries of the Colorado River.
Topsoil is the upper layer of soil. It has the highest concentration of organic matter and microorganisms and is where most of the Earth's biological soil activity occurs.
The San Joaquin Valley is the southern half of California's Central Valley. Famed as a major breadbasket, the San Joaquin Valley is an important source of food, producing a significant part of California's agricultural output.
Soil conservation is the prevention of loss of the topmost layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination.
Nonpoint source (NPS) pollution refers to diffuse contamination of water or air that does not originate from a single discrete source. This type of pollution is often the cumulative effect of small amounts of contaminants gathered from a large area. It is in contrast to point source pollution which results from a single source. Nonpoint source pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage, or hydrological modification where tracing pollution back to a single source is difficult. Nonpoint source water pollution affects a water body from sources such as polluted runoff from agricultural areas draining into a river, or wind-borne debris blowing out to sea. Nonpoint source air pollution affects air quality, from sources such as smokestacks or car tailpipes. Although these pollutants have originated from a point source, the long-range transport ability and multiple sources of the pollutant make it a nonpoint source of pollution; if the discharges were to occur to a body of water or into the atmosphere at a single location, the pollution would be single-point.
Surface runoff is the unconfined flow of water over the ground surface, in contrast to channel runoff. It occurs when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or human-made processes.
An hydrological transport model is a mathematical model used to simulate the flow of rivers, streams, groundwater movement or drainage front displacement, and calculate water quality parameters. These models generally came into use in the 1960s and 1970s when demand for numerical forecasting of water quality and drainage was driven by environmental legislation, and at a similar time widespread access to significant computer power became available. Much of the original model development took place in the United States and United Kingdom, but today these models are refined and used worldwide.
The Kesterson Reservoir is part of the current San Luis National Wildlife Refuge in California. Formerly a unit of the Kesterson National Wildlife Refuge, the reservoir was an important stopping point for migratory waterfowl. Kesterson once consisted of 12 evaporation ponds totaling approximately 1,280 acres, and was historically used for agricultural drainage. Kesterson gained national attention during the latter half of the 20th century due to selenium toxicity and rapid die off of migratory waterfowl, fish, insects, plants and algae. The reservoir was closed in 1986, and concentrations of selenium at the site have continued to be monitored throughout remediation efforts.
Algae fuel, algal biofuel, or algal oil is an alternative to liquid fossil fuels that uses algae as its source of energy-rich oils. Also, algae fuels are an alternative to commonly known biofuel sources, such as corn and sugarcane. When made from seaweed (macroalgae) it can be known as seaweed fuel or seaweed oil.

The environmental impact of agriculture is the effect that different farming practices have on the ecosystems around them, and how those effects can be traced back to those practices. The environmental impact of agriculture varies widely based on practices employed by farmers and by the scale of practice. Farming communities that try to reduce environmental impacts through modifying their practices will adopt sustainable agriculture practices. The negative impact of agriculture is an old issue that remains a concern even as experts design innovative means to reduce destruction and enhance eco-efficiency. Animal agriculture practices tend to be more environmentally destructive than agricultural practices focused on fruits, vegetables and other biomass. The emissions of ammonia from cattle waste continue to raise concerns over environmental pollution.
The San Joaquin Valley of California has seen environmental issues arise from agricultural production, industrial processing, and the region's use as a transportation corridor, experiencing some of the nation’s worst air quality, high rates of childhood asthma, and contaminated drinking water.
Restore the Delta is a campaign, based in Stockton, California that advocates for restoring the Sacramento-San Joaquin Delta also known as the San Francisco Bay-Delta Estuary. It began in 2006 working towards education and outreach to help Californians recognize the Delta as part of California's heritage. Currently, there are up to 40,000 members throughout California of both residents and various organizations working towards the same goal.
