Legacy Lead In Urban Garden Soils: Communicating Risk And Limiting Exposure, Anna Paltseva, Zhongqi Cheng, Murray Mcbride, Maha Deeb, Sara Perl Egendorf, Peter M. Groffman Jun 2022

Legacy Lead In Urban Garden Soils: Communicating Risk And Limiting Exposure, Anna Paltseva, Zhongqi Cheng, Murray Mcbride, Maha Deeb, Sara Perl Egendorf, Peter M. Groffman

Advanced Science Research Center

Lead (Pb) exposure has long been recognized as a hazard to human health. Urban garden soils often contain elevated levels of Pb, mainly from legacy sources, which is a main barrier for urban gardening. The capacity of gardeners to access, understand, and act on scientific data related to soil contamination is also variable. This synthesis paper briefly summarizes the current scientific knowledge on soil Pb in urban gardens. Our objective is to produce clear recommendations about assessing actual risks and limiting exposure. First, we synthesize the nature and extent of soil contamination with Pb, and then describe how the bioavailability …


Developing A Miniature Smart Boat For Marine Research, Michael Isaac Eirinberg Jun 2022

Developing A Miniature Smart Boat For Marine Research, Michael Isaac Eirinberg

Computer Engineering

This project examines the development of a smart boat which could serve as a possible marine research apparatus. The smart boat consists of a miniature vessel containing a low-cost microcontroller to live stream a camera feed, GPS telemetry, and compass data through its own WiFi access point. The smart boat also has the potential for autonomous navigation. My project captivated the interest of several members of California Polytechnic State University, San Luis Obispo’s (Cal Poly SLO) Marine Science Department faculty, who proposed a variety of fascinating and valuable smart boat applications.

High Spatial And Temporal Resolution Census Data Reveal Communities At Risk Along The Wildland-Urban Interface (Wui) In California, Usa, Shenyue Jia, Slade Lazeweski, Jessica E. Viner, Wesley Ho, Brian Hoover May 2022

High Spatial And Temporal Resolution Census Data Reveal Communities At Risk Along The Wildland-Urban Interface (Wui) In California, Usa, Shenyue Jia, Slade Lazeweski, Jessica E. Viner, Wesley Ho, Brian Hoover

Institute for ECHO Articles and Research

We tracked census tract level population change along California's wild land-urban interface (WUI) during the past decade (2010-2019), an ecological sensitive region transitioning from developed land to wilderness. Our results from Mann-Kendall analysis, a method employed for monotonic trend detection showed that about one-third (29.1%) of census tracts in California’s WUI have seen a significant population increase from 2010 to 2019, affecting 12.7% population in California. The population increase along WUI is largely driven by the sixteen counties in the San Francisco Bay Area (10) and Southern California (6). We also found that higher proportion of WUI residents in Bay …


Identifying Associations Between Human-Environmental Factors And Water Quality Trends Observed At Perennial Headwater Streams Of The San Bernardino National Forest, California, Anna Frey May 2022

Identifying Associations Between Human-Environmental Factors And Water Quality Trends Observed At Perennial Headwater Streams Of The San Bernardino National Forest, California, Anna Frey

Electronic Theses, Projects, and Dissertations

Anthropogenic factors related to landscape activities, infrastructure, and alterations, coupled with severe climatic fluctuations (i.e., droughts and extreme hydrological events) are increasingly impairing the quality of surface water resources across multiple geographic scales, warranting the need for comprehensive investigations of the cumulative effects of human-environmental stressors at multiple scales within a watershed. This study assessed three perennial headwater streams of the San Bernardino National Forest, California. The streams were tested for one year from October 2019 to September 2020 for conductivity, dissolved oxygen (DO), pH, turbidity, temperature, ammonium (NH4+), nitrate (NO3-), total coliform (TC), Escherichia coli …


Identification And Analysis Of The Contribution Of Various Sources Of Total Dissolved Solids (Tds) In Lake Elsinore Potable Water And Wastewater, Lenai Hunter May 2022

Identification And Analysis Of The Contribution Of Various Sources Of Total Dissolved Solids (Tds) In Lake Elsinore Potable Water And Wastewater, Lenai Hunter

Electronic Theses, Projects, and Dissertations

Total Dissolved Solids (TDS) are primarily inorganic salts that can pass through a 2-micron (or smaller) filter and, when found in high concentrations, can cause adverse effects on aquatic organisms and the surrounding environment. The agency servicing Lake Elsinore and surrounding areas is the Elsinore Valley Municipal Water District (EVMWD). EVMWD’s wastewater treatment facilities are not equipped to remove TDS from the wastewater. Therefore, the influent TDS values are often similar to the final treated effluent recycled water TDS values. EVMWD has permit limits at the wastewater treatment plants relating to TDS, and due to the higher influent TDS concentrations …
