In urbanized watersheds, storm water discharges from industrial facilities are a potentially major but poorly understood source of pollutants. Estimates of pollutant load from industrial facilities may vary with many factors, but must be refined if watershed based regulations, such as the Total Maximum Daily Load (TMDL) program, are to be implemented fairly and effectively. Storm water runoff from industrial facilities under the NPDES program are regulated through a general permit, which among requires facility operators to implement a limited monitoring program. This research used monitoring data reported by industrial facilities to estimate the contribution of pollutant load into the upper San Gabriel watershed in the Los Angeles region. First, we attempted to control for data variability caused by factors such as facility size, impervious portion of surface area, rainfall intensity, and seasonal antecedent rainfall, but no relationships were identified. Next, we estimated total loads from industrial facilities in the watershed. Industrial facilities constituted less than one percent of the watershed area, but contributed between 10% and 70% of total copper load and between 15% and 60% of total zinc load. Load estimates were strongly affected by variability in concentration data and estimates of the number of non-compliant facilities, but less strongly by spatial variability in rainfall.

World Water and environmental Resources Congress 2001

作者： Augustenborg, Cara A. Duke, L. Donald UCLA Environmental Health Sciences Department United States Environmental Science and Engineering Program School of Public Health University of California Los Angeles CA 90095-1772 United States

ISBN: (纸本)0784405697

This research is designed to evaluate effectiveness of current regulations for control of pollutants in stormwater runoff from industrial facilities, and resulting efforts by the regulated community to reduce pollutants. For three targeted municipalities, the research first assesses the approximated proportion of industrial facilities that have recognized their duty to comply since the promulgation of permits under NPDES in the early 1990s. The research examines the proportion of facilities subject to regulations that have filed Notice of Intent (NOI) and the number of new NOIs filed each year since the regulations took effect in 1992. Then, the research determines for each municipality the industry types with the greatest number of NOIs filed. The purpose of these analyses is to characterize trends and patterns of compliance by industrial facilities within the regions, in order that future efforts may attempt to link those trends with observed water quality changes in the targeted municipalities. The total number of facilities in compliance can be influenced by unique facility types in different regions;by the diligence of regulatory and outreach effects by state and local agencies in different regions;and various other factors. The method is based on databases containing industrial facility compliance information. In this way, the research evaluates the relative effectiveness of municipal programs at achieving the pollutant reduction goals of the storm water NPDES regulations. Copyright ASCE 2004.

Fine particle air pollution is characterized and source contribution to that fine particle air pollution is quantified in Delhi. Average fine particle mass concentrations were 231±2 μg m-3 during the winter and 50±1 μg m-3 during the summer. Organic carbon (OC), elemental carbon (EC), NO3-, SO42-, Cl-, NH4+, and trace metals were analyzed. Organic matter (OM) and EC were respectively 58% and 8% during winter and 46% and 8% during summer. Sulfate contributed much of the rest. Relative contributions of crustal oxides or dust to the fine particle mass reached a peak during the spring and the summer time in all the cities. Fifty-five organic compounds were also quantified using GC/MS techniques. Summertime concentrations for levoglucosan, picene, and the sum of hopanes and steranes were respectively 210±40 ng/m3, 0.3±0.06 ng/m3, and 8.5±1.7 ng/m3 and wintertime concentrations for the same compounds were respectively 5300±1100 ng/m3, 5.1±1.0 ng/m3, and 80±16 ng/m3. These measured concentrations of organic carbon from Delhi were used in a molecular marker source apportionment model to quantify the primary source contributions to the PM2.5 mass concentrations. Five important sources were identified and quantified: diesel exhaust, gasoline exhaust, road dust, coal combustion, and biomass combustion. Important trends in the seasonal and spatial patterns of the impact of these five sources were observed. Primary emissions from fossil fuel combustion (coal, diesel, and gasoline) were responsible for 22-33% of PM 2.5 mass compared to the biomass combustion contributions to ambient PM2.5 of 9-28%.

Proceedings of the A and WMA's 97th Annual Conference and Exhibition;Sustainable Development: Gearing Up for the Challenge

Tiefenthaler, Liesl Southern California Coastal Water Research Project 7171 Fenwick Lane Westminster CA 92683 Environmental Science and Engineering Program University of California School of Public Health Los Angeles CA 90095 Department of Civil and Environmental Engineering University of California Los Angeles CA 90095

Emissions of trace metals to the atmosphere and subsequent deposition, either directly to the waterbody surface or indirectly to the watershed for wash off during rain events, may contribute to the contamination observed in surface waters throughout the urban Los Angeles region. The goal of this study was to provide empirical data on atmospheric concentrations of trace metals on coarse particles and to estimate the direct and indirect mass loading of these trace metals due to dry atmospheric deposition in coastal watersheds of the Los Angeles Air Basin. To achieve this goal, atmospheric concentrations of chromium, copper, lead, nickel and zinc were measured seasonally using a Noll Rotary Sampler at six urban and one nonurban site throughout the Los Angeles coastal air basin. Dry deposition fluxes were calculated by summing the product of air concentration and theoretical deposition velocities of four coarse particle fractions (6-11, 11-20, 20-29, and >29 μm). Mean annual fluxes at urban sites ranged from 3.2 to 9.1, 11 to 34, 3.8 to 8.8, 8.3 to 29, and 69 to 228 μg/m2/day for chromium, copper, nickel, lead and zinc, respectively. Mean fluxes at the urban sites were significantly higher than the nonurban site. Comparisons for the Los Angeles River indicated direct dry atmospheric deposition produced a relatively small load of trace metals to that waterbody. In contrast, indirect dry deposition was potentially a very large source of trace metals to watershed loadings based on comparisons to load estimates from stormwater runoff.

ISBN: (纸本)0784405697

This research evaluated actions taken by auto dismantling facilities in the Los Angeles, California, region as part of required compliance with regulations for industrial storm water discharge. Eight years after California issued a General Permit for storm water under the National Pollutant Discharge Elimination System (NPDES), a large number of dismantlers have failed to recognize their duty to comply;about 20% of identified facilities do not appear to have notified regulating agencies of their intent to comply. The research then evaluated a sample of complying facilities. The research involved storm water sampling at a smaller number of case study facilities, and determined that a large proportion have measured constituents in discharges in concentrations exceeding U.S. guidelines for storm water - not an enforced requirement, because the regulations do not specify numerical effluent limits. Estimates of pollutant load contributed by the dismantling industry appear substantial. Copyright ASCE 2004.

Hydrophobic organic compounds, such as polycyclic aromatic hydrocarbons (PAHs), demonstrate a high affinity for fine particles, the so-called suspended solids or sediments (SS) in natural waters. This study focused on PAHs from the SS collected from non-point source runoff into Santa Monica Bay, California. The runoff came from the urbanized Los Angeles watershed of Ballona Creek, which is approximately 325 square kilometers in size and developed primarily with residential and light commercial industries. In the 1997-98 rain season, an El Nino year, storm events were monitored to show the pattern of non-point source runoff. The primary objective of this study was to determine the types and concentrations of organic pollutants associated with the suspended solid phase. A calculation of the mass of the pollutants for each storm was conducted. Other objectives included 1) to study for the relationship between storm flow and pollutant loading, including the determination of a first flush, 2) to compare concentration of pollutants with an environmental indicator and 3) to do a simple comparison between point source and non-point source sources of pollution. Seventeen PAHs were detected frequently during the storm. Only, fluoranthene and pyrene were detected in all twenty-four samples analyzed and chrysene and phenanthrene were detected in all but the first sample. Five of seven low molecular weight polycyclic aromatic did not show a first flush for the December storm at Ballona Creek. The high molecular weight PAHs showed a moderate first flush. The estimated mass load calculated for the PAHs for Ballona Creek was 4.1 kg for the December 1997 storm. The mass of the all PAHs from this storm is equivalent to the allowable effluent for 6.4 months of PAHs from an oil refinery located on Santa Monica Bay. Copyright ASCE 2004.

Electric, water, gas and transportation utilities face severe challenges associated with security, quality, availability, reliability and profitability issues. They must solve interrelated system problems with respect to generation of electricity, transportation of fuel, and potable as well as waste water. In the future, engineers and managers of utilities must be well versed in the different disciplines of engineering including electrical civil, mechanical and information technology. The University of Colorado at Boulder addresses this educational opportunity by proposing a novel Integrated Utilities Management program for M.S. candidates who have a solid B.S. background or equivalent in a related discipline. The M.S. program will consist of four interdisciplinary paths dealing with business management and legal topics as they relate to federal and state regulatory issues, as well as agency and people-related leadership issues. The electric utilities option of this program will be centered on three core courses related to electric power generation/transmission and distribution, security and availability, quality and reliability, economics and environmental policy, and utility finance;two elective courses from a group of courses that address nuclear power, waste water, solid waste, telecommunications, renewable energies, data communication, fuels and case studies;and one capstone course consisting of either operations research or the investigation and resolution of a pending utility project such as the right-of-way of transmission lines, specification of new power plants, retrofitting of power plants or their impact on the environment. It is expected that candidates for this MS program will come from universities, from utilities, and from private and public agencies. The MS program can be completed by full- or part time students within one or two years of intensive study, respectively. Courses will be taught both on campus and nationwide via the Center for Advanced

A real-time and integrated measurements of pollutant concentrations were investigated in diesel school buses to determine the range of children's exposures during their bus commutes. The exposures resulted primarily from the commute itself and not from loading, unloading or waiting at bus stops. The rear of the bus with windows closed tended to have higher pollutant concentrations, which appear to originate from self-pollution. The use of cleanest buses for the longest routes and minimizing the commute times can reduce children's exposures to bus-related pollutants.

The potential for an Ecological Treatment System (ETS) to improve water quality of highly concentrated dairy wastewater is supported by the effective treatment of municipal wastewater by previous ecological systems such as Living Machines™, algal scrubbers, and treatment wetlands. This study utilized a lab-scale ETS that consisted of six components;three aerated vegetative tanks, one anaerobic tank, one clarifier, and one wetland mesocosm, resulting in a total water volume of 878 L. This system treated dairy wastewater added in increments of 7.5, 15, and 22.5 L every 72 hours. The influent CBOD5 of the waste averaged 1490.46 mg L-1. Regardless of loading rate, the system consistently reduced CBOD5 concentrations more than 99%. Percent reductions for the following variables were not affected by the different loading rates;TSS (96.5%), PC (99.5%), POC (99.2%), and TN (87.1%). However, there was a significant difference (R-ANOVA, p-value 4-N, PO4-P, and TP. Reduction rates greater than 99% were measured for NH4-N, TP, and TSS for all loading rates. However, TSS and NH4-N did not meet effluent discharge goals of 10 mg L-1 and 0.1 mg L-1, respectively, at loading rates of 22.5 L, and TP did not meet the effluent discharge goal of 1 mg L-1 for any of the loading rates. The effectiveness of the system to remove NO 3-N was limited by the bio-availability of carbon. At the lowest loading rate (7.5 L), there were no reductions in concentrations of NO 3-N. However, at the highest loading rate (22.5 L) the NO 3-N was reduced to zero during the first 3 hours of treatment. The dependence of nitrate reduction on the bio-availability of carbon was supported by an inverse relationship (r2=0.77) between PC and nitrate at the highest loading rate.
