Sean Noble

Project Scientist

Mr. Sean Noble has more than 5 years of experience supporting multiple water quality, stormwater, and sediment coring projects. He has performed stormwater and dry-weather sampling in various environments, such as estuaries, streams, and channels, and within structural best management practices (BMPs), such as permeable pavement, bioretention areas, and media filters. He is also responsible for database management, the development of programming tools, statistical analyses, hardware troubleshooting and calibration, automated sampler development and programming, GIS work, environmental modeling, and document preparation.

Mr. Sean Noble has more than 5 years of experience supporting multiple water quality, stormwater, and sediment coring projects. He has performed stormwater and dry-weather sampling in various environments, such as estuaries, streams, and channels, and within structural best management practices (BMPs), such as permeable pavement, bioretention areas, and media filters. He is also responsible for database management, the development of programming tools, statistical analyses, hardware troubleshooting and calibration, automated sampler development and programming, GIS work, environmental modeling, and document preparation. Mr. Noble provides a key support role in the coordinated integrated monitoring programs (CIMPs) for several watersheds in Los Angeles County, which are monitored according to the NPDES municipal separate storm sewer system (MS4) regional stormwater discharge permit (issued by the Los Angeles Regional Water Quality Control Board), where he developed tools to automate data interpretation and QA/QC evaluations. He is also responsible for hydrologic analysis, modeling, and project support for the low-impact development program for the California Regional Water Quality Control Board, San Francisco Bay Region. Mr. Noble also provides key field support for the Calleguas Creek Watershed Management Group in Ventura County and the Central Coast Environmental Assessment Network.

Mr. Noble worked for 4 years as a water resources technician for the Monterey County Water Resources Agency, where he managed sustainability efforts for the Salinas River watershed and two reservoirs that serve more than 200,000 residents. He designed and implemented plans to utilize water resources in Monterey County effectively and minimize negative impacts on communities that depend on that service while also creating strategic plans for a sustainable future. He also developed science-based remote sensing tools using large data sets to assess the past and present hydrologic status of the Salinas Valley while overseeing the flood alert network and program management.

Water Quality Monitoring

Central Coast Environmental Assessment Network, Santa Cruz, California Supports this sampling program in multiple ways, including onshore and offshore development and maintenance of state-of-the-art in situ organic compound extraction, river and water treatment facility monitoring for trace persistent organic pollutants (POPs), and mussel (Mytilus californicanus) collection for POPs. Also manages the project database and performs data analysis.
Lower Los Angeles River, Los Cerritos Channel , and San Gabriel River Enhanced Watershed Management Program Group CIMP, Los Angeles County, California Ensures data conform to the California Environmental Data Exchange Network (CEDEN) format, manages the project database, prepares report figures, develops data processing tools, and performs data QA/QC.
Municipal Regional Stormwater Permit Compliance Monitoring, Contra Costa, San Mateo, Santa Clara, and Alameda Counties, California Performs hydrologic flow calculations, data management and QA/QC, sampler programming, GIS and light detection and ranging (LiDAR) analyses, and hydrologic modeling. Assists in storm tracking and sample event preparation and management, hardware maintenance and installation, and sampling protocol improvements. Collaborates in an interagency group on experimental design, annual reporting, statistical analysis, and program presentations.
Calleguas Creek Watershed Total Maximum Daily Load (TMDL) Monitoring Program, Ventura County, California Conducts sampling for dry- and wet-weather water quality investigations with a focus on efficiency, sample integrity, and safety. Serves as field lead for sampling events that encompass the entire Calleguas Creek watershed with multiple hydrological considerations. Authored the handbook for training and referencing to ensure field flow measurements comply with project requirements. Conducts data preparation and QA/QC as well as the calibration and maintenance of equipment for measuring water pH, temperature, dissolved oxygen, turbidity, and conductivity.
City of Long Beach Shoreline Indicator Bacteria Recreational Water Quality Monitoring, Long Beach, California Performs data QA/QC and database management. Also designs and implements data processing and web-scraping tools. Performs statistical data analyses and creates data graphs illustrating trends for reporting.
PCBs and Mercury in Stormwater, California Assists with flow-based water quality measurements and sampling for legacy mercury and PCB contamination in outfalls and storm drains.
Caltrans TMDL Monitoring, California Designed the statistical analysis approach to test water quality and volume changes for the Santa Nella porous pavement overlay BMP project. The ensemble of data from three different test treatments and one control treatment is subject to normality and equal variance testing to determine whether a parametric or nonparametric analysis is applicable. The null hypothesis that there is no statistical difference between any of the test or control overlays is then tested by a one-way analysis of variance or by a nonparametric Wilcoxon test. Participates in semiannual field testing of the porous overlay permeability that is done to analyze changes to the test pavement porosity over time.

Dredged Material Management

Dredge Sediment Characterization in Federal Channels within Bays and Harbors for U.S. Army Corps of Engineers (USACE), Los Angeles District, Southern California Participated in marine sediment sampling to safely collect sediment cores in and around harbors, rivers, reservoirs, and estuaries throughout Southern California. Main responsibilities included equipment setup and deployment and the operation of a small support vessel.
Dredge Sediment Studies, USACE, San Francisco District, Northern California Participated in sediment sampling across various Northern California bays and harbors, including Humboldt Bay, Noyo Harbor, Redwood City, Oyster Point, San Leandro, Oakland Inner and Outer Harbor, Richmond Inner and Outer Harbor, Petaluma Approach Channels and River, Napa River, Montezuma Slough, Suisun Bay, and Crescent City Harbor as an equipment and small boat operator.
