Stormwater practitioners need quantitative information about the quality and volume of highway runoff to assess and mitigate potential adverse effects of runoff on the Nation’s receiving waters. The U.S. Geological Survey developed the Highway Runoff Database (HRDB) in cooperation with the FHWA to provide practice-ready information to meet these information needs on the local or national scale. This paper describes the datasets that are available in version 1.1 of the HRDB and demonstrates how data and statistics from the HRDB can be used with the Stochastic Empirical Loading and Dilution Model (SELDM) to simulate highway runoff. The HRDB includes 249 sites, 6,849 runoff events, and 106,869 event mean concentrations (EMCs) collected during the 1975–2017 period. It includes data from 16 States in the conterminous United States and from Hawaii. The EMCs in the HRDB include measurements for 415 different water-quality constituents. These water-quality measurements include 32,944 trace-metal; 27,496 organic; 15,684 nutrient; 13,016 physical property; 10,307 major inorganic; 6,773 sediment; and 649 other constituent values. There are large variations in the data. For example, EMCs for total suspended solids and total phosphorus range from 0.4 to 5,440 mg/L and 0.004 to 22 mg/L, respectively; geometric means range from 1.58 to 1,379 mg/L and 0.017 to 2.82 mg/L for these constituents, respectively. The example simulations indicate that risks for adverse effects of runoff can vary by orders of magnitude; the HRDB and SELDM facilitate selection of representative statistics from available datasets.

Storm water runoff is a major contributor to the pollution of receiving waters. Storm water characteristics may vary significantly between locations and events. Hence, for each given location, this necessitates a well-designed monitoring campaign prior to selection of an appropriate storm water management strategy. The challenge for the design of a monitoring campaign with a given budget is to balance detailed monitoring at a limited number of locations versus less detailed monitoring at a large number of locations. This paper proposes a methodology for the selection of monitoring locations for storm water quality monitoring, based on (pre-)screening, a quick scan monitoring campaign, and final selection of locations and design of the monitoring setup. The main advantage of the method is the ability to prevent the selection of monitoring locations that turn out to be inappropriate. In addition, in this study, the quick scan resulted in a first useful dataset on storm water quality and a strong indication of illicit connections at one of the monitoring locations.

The Oregon Department of Transportation (ODOT) and other state departments of transportation need quantitative information about the percentages of different land cover categories above any given stream crossing in the state to assess and address roadway contributions to water-quality impairments and resulting total maximum daily loads. The U.S. Geological Survey, in cooperation with ODOT and the FHWA, added roadway and land cover information to the online StreamStats application to facilitate analysis of stormwater runoff contributions from different land covers. Analysis of 25 delineated basins with drainage areas of about 100 mi2 indicates the diversity of land covers in the Willamette Valley, Oregon. On average, agricultural, developed, and undeveloped land covers comprise 15%, 2.3%, and 82% of these basin areas. On average, these basins contained about 10 mi of state highways and 222 mi of non-state roads. The Stochastic Empirical Loading and Dilution Model was used with available water-quality data to simulate long-term yields of total phosphorus from highways, non-highway roadways, and agricultural, developed, and undeveloped areas. These yields were applied to land cover areas obtained from StreamStats for the Willamette River above Wilsonville, Oregon. This analysis indicated that highway yields were larger than yields from other land covers because highway runoff concentrations were higher than other land covers and the highway is fully impervious. However, the total highway area was a fraction of the other land covers. Accordingly, highway runoff mitigation measures can be effective for managing water quality locally, they may have limited effect on achieving basin-wide stormwater reduction goals.


<em>Abstract</em>.—We surveyed production managers of state natural resource agencies with striped bass <em>Morone saxatilis </em>and white bass <em>M. chrysops </em>× striped bass hybrid stocking programs to identify information needs and opportunities for shared innovations. Among 18 states responding, 17 reported ongoing fish transportation and stocking activities involving striped bass or striped bass hybrids. Oxygen diffusion was the most commonly reported treatment of fingerlings during transport, and the majority of respondents reported using agitators or aerators in hauling units. Sodium chloride was the most common additive used to condition hauling unit water, and five states also reported use of calcium chloride. Water quality monitoring procedures were less consistent among respondents, especially for receiving waters at stocking sites; only water temperature measurement was reported by all respondents. Although the majority of responding agencies reported monitoring fingerling survival during hauls, postrelease monitoring of fingerling survival was uncommon, in spite of the potential impact of release site water quality conditions on fingerling survival. Survey responses generally reflected improvements in consistency, with established guidelines since earlier surveys, but revealed an ongoing focus on prerelease condition of fingerlings as the primary measure of success of striped bass and striped bass hybrid stocking programs. We recommend that postrelease fingerling survival should be more widely monitored and used to determine success of stocking programs.

Abstract A summary of selected Canadian experiences in the application of biological tests for controlling and monitoring effluent quality, for setting water quality objectives, and for monitoring receiving waters is presented. ? brief review is made of the approaches for applying biological tests to effluents, to the selection of suitable water quality objectives, and to the conduct of ambient biomonitoring programs. Two case examples from Canada, the Saint John River, New Brunswick, and Canagagigue Creek, Ontario, are evaluated in detail. A number of other Canadian sites where biological tests are being applied are also discussed. The contributions of biological tests on effluents to administrative decisions for pollution control, as well as the limitations of solely using “end of pipe” tests, are emphasized in the paper.

A biomonitoring program has been developed in support of the National Policy for the Development of Water Quality-Based Permit Limitations for Toxic Pollutants. The program focuses on the use of laboratory toxicity tests on aquatic plants and animals to predict ecosystem impact caused by toxic pollutants. Both acute and chronic toxicity tests were developed to test effluents and ambient waters. Laboratory and biological field studies were conducted at nine sites. Single species laboratory toxicity tests were found to be good predictors of impacts on the ecosystem when two or more species were used. Biomonitoring can be undertaken either on effluents and/or on the receiving waters. In that toxicity related to seeps, leachates and storm sewers has often been found upstream from dischargers, it is beneficial to conduct both effluent and ambient biomonitoring.
