  • Acid Rain Monitoring Project – Statewide Coordinator
    As Statewide Coordinator and Co-principal Investigator, Armand managed a statewide, multi-year surface water quality research project in Massachusetts. This project involved coordinating a statewide network of over 1000 monitoring volunteers and 75 local laboratories. View Report (3.8MB PDF)


Data Analysis, Management and Reporting
Armand Ruby Consulting consistently produces insightful analyses of monitoring data, and packages the results into clear, readable reports. The goal is to help clients make beneficial use of their investments in water quality monitoring. Recent examples include the following projects:

  • Analysis of Bay Area Urban Creeks Monitoring
    Armand developed a regional urban creeks monitoring plan for the Clean Estuary Partnership's Diazinon/Toxicity Work Group, and oversaw its implementation in 2005. Armand analyzed the monitoring data, including water and sediment chemistry and toxicity testing results, and produced a comprehensive report with interpretive analysis and recommendations for future monitoring. View Report (2.3MB PDF)
  • Caltrans Discharge Characterization Study
    Armand directed a comprehensive analysis of the Caltrans statewide discharge characterization data set. The report includes an overview of Caltrans stormwater characterization activities, descriptions of the methods used to produce and evaluate the data, summaries of the results of the characterization monitoring and data analysis, and discussion of findings pertinent to management of stormwater runoff from transportation facilities. View Report (18.3MB PDF)
  • Caltrans Data Management Process
    Armand oversaw the development of the Caltrans data management process, including the creation of a statewide, GIS-based water quality database for Caltrans stormwater runoff monitoring data, with user-friendly interface and interactive data query screen. Visit Caltrans Website


Mass Loading Modeling/Calculations
Armand Ruby is an innovator in statistical analysis of monitoring data, including the difficult task of estimating mass loadings from stormwater runoff discharges, which are both intermittent and highly variable. The following project is a recent example of these capabilities:

  • Sacramento Urban Runoff Discharge Characterization
    Armand developed a detailed statistical characterization of runoff discharges, including regression equations to relate runoff quality to hydrological factors, coupled with continuous simulation modeling to produce mass loadings from urban runoff discharges. Results are separated by wet and dry weather, urban drainage area, and major receiving water destination. View Report (4MB PDF)


Watershed Assessment and TMDL Analyses
In recent years Armand has been active in conducting watershed-wide assessments and analyses related to development and implementation of TMDLs. Examples include:

  • Calleguas Creek Watershed TMDLs
    While with Larry Walker Associates, Armand played a key role in the development of TMDLs in the Calleguas Creek watershed (Ventura County). As manager of LWA's Technical Tools team, Armand was responsible for data management, data analysis, water quality modeling, and development of a graphical user interface for an empirically-based water quality model.

  • San Francisquito Creek LTMAP Data Analysis
    Armand compiled, organized and analyzed all water quality data produced under the Long Term Monitoring and Assessment Plan from 2001-2006 from four creek monitoring stations in the San Francisquito Creek watershed. Armand presented the analysis and interpretation of the results to the LTMAP work group and recommended modifications to the monitoring program. View Report (581K PDF)
  • Yolo Bypass Water Quality Data Analysis
    Armand oversaw the compilation and analysis of the extensive water and sediment quality data set generated by the Yolo Bypass monitoring program, including chemistry and toxicity testing data collected from numerous surface water monitoring sites monthly over a one year period. Armand presented the results at the 2005 California Non-Point Source Conference. View Presentation (1.4MB PDF)

    Armand managed an investigation of the potential effects of atmospheric deposition on urban runoff quality in the Sacramento metropolitan area, focusing on the potential atmospheric transport of pollutants from the San Francisco Bay Area to the Central Valley.


Water and Sediment Quality Monitoring
Armand Ruby is a recognized expert in environmental monitoring and assessment. Projects have involved analysis of water and sediment chemistry, aquatic and sediment toxicity testing, bioassessment (freshwater benthic macroinvertebrate assemblages), precipitation chemistry, groundwater chemistry, and various other physical and biological parameters. Armand has been a leading proponent of clean sampling techniques in California since the early 1990's. Recent monitoring projects include work in the following areas:
