Introduction

The New York State Department of Transportation (NYSDOT) is evaluating alternative treatments for road deicing with the goal of reducing the impact of this activity on the State’s water resources. The NYSDOT has requested support from the U. S. Geological Survey (USGS) in monitoring the effects of these alternative treatments on the water resources. In the past, the USGS has cooperated with State transportation agencies in studies to evaluate road-deicer concentrations in Massachusetts (Church and others, 1996; Granato and Smith, 1999; and Smith and Granato, 2010) and to determine the impacts on water resources in Ohio and Indiana that included the application of surface-and borehole-geophysical technologies (Risch and Robinson, 2001; Watson and others, 2002; and Kunze and Sroka, 2004). A USGS-State cooperative study in Massachusetts (Church and others, 1996) evaluated engineering methods to mitigate the impact of road deicing on groundwater through well-cluster monitoring and electromagnetic-induction logging (figs. 1 and 2). A current USGS-State cooperative study in Massachusetts is monitoring road-salt runoff and pavement conditions using automated sampling techniques and road-weather sensor technologies (figs. 3a.3b).
As a pilot demonstration, the NYSDOT has identified road sections for abrasive and low-salt treatments along State Route 86 between Lake Placid and Wilmington, and a control section with typical deicing treatment along State Route 35 (fig. 4). Exploratory wells drilled by the NYSDOT in the right of way of the road sections penetrated coarse-grained alluvial-glacial deposits overlying bedrock at depths of less than 5 to more than 35 feet below land surface. The depth to the water table at the drill sites was less than 10 feet from land surface.

Objectives

The objectives of the proposed study are to evaluate the effectiveness of abrasive and low-salt road-deicing treatments in reducing chloride concentrations and loads in the surface-water and groundwater systems, and to provide the NYSDOT with data to help them evaluate the effectiveness of alternative winter roadway maintenance methods.

Approach

The USGS proposes to establish and maintain a water-resource and road-runoff monitoring network through the integrated application of highway-runoff drain and cluster-well water sampling, electromagnetic surveying and logging, and road-weather sensor technology. The study approach builds upon previous and current Federal-State cooperative road-salt studies and applies state-of-the-art water-resource and geophysical methods. The proposed approach is summarized, by task, as follows:

Geophysical Surveys
1. Collect gamma and electromagnetic-induction logs and groundwater samples for field measurement of specific conductance and temperature at the four exploratory well sites (fig. 4) to provide preliminary data on the thickness of the aquifer (saturated coarse-grained deposits) and salinity of groundwater in the study area. This data along with the drilling logs of the exploratory wells will be used in the initial interpretation of the surface-geophysical surveys.
2. Conduct passive-seismic and frequency-domain electromagnetic (GEM2) surveys of the upgradient and downgradient areas of the proposed control, abrasives, and low-salt treatment groundwater-monitoring locations (fig. 4). The non-invasive surface-geophysical data will be analyzed to estimate the three-dimensional spatial distribution of aquifer framework and groundwater salinity at the proposed locations and confirm their suitability for groundwater monitoring.
3. Collect gamma and electromagnetic-induction logs and pumping tests at the six cluster-well sites (fig. 4).
Groundwater Monitoring
1. Install and maintain downhole monitoring sensors in the six shallowest cluster wells for continuous measurement of groundwater level, specific conductance, and temperature. Real-time web dissemination of the data from the downgradient well at the abrasive location.
2. Collect water samples seasonally (four to five times a year) from each cluster well, and from each cluster well. Submit the samples to the USGS National Water Quality Laboratory for major cation and anions analyses.
3. Conduct frequency-domain electromagnetic (GEM2) surveys and electromagnetic-induction logging seasonally (four to five times a year) at the three groundwater-monitoring locations.
Surface-Water Monitoring
1. Install and maintain in-stream monitoring sensors for continuous measurement of specific conductance and temperature at 3 sites along the Ausable River and 6 sites (upgradient and downgradient sites on 3 unnamed tributary streams) (fig. 4).
2. Install one streamgage along the Ausable River and make miscellaneous measurements at 6 tributary-stream sites. Mathematical analysis will be done using miscellaneous measurements to estimate daily discharge at all tributary sites.
3. Collect water samples seasonally (four to five times a year) from the tributary-stream sites. Submit the samples to the USGS National Water Quality Laboratory for major cation and anions analyses.
Highway Runoff and Road-Condition Monitoring
1. Install and maintain continuous flow, specific-conductance, and temperature data-collection sensors at three highway-runoff monitoring sites and real-time web dissemination of the data.
2. Install equipment to continuously monitor highway runoff and automatically collect discrete and flow-weighted composite samples of runoff from each section of highway. Additional equipment will be installed to monitor precipitation, snow depth, and air temperature of highway runoff at each test site. Non-contact and in-pavement sensors will be installed at each test location to monitor road surface temperature, road moisture conditions (damp, wet, ice, snow, etc.), pavement friction, and chemical-active state. In-pavement sensors will be installed during the second year after the highway sections are resurfaced.
3. Periodically collect composite samples of highway runoff from each test sites for 15-18 selected storms over a 2-year period. These composite samples of highway runoff will be analyzed for total nutrients, major ions, selected trace elements, and suspended sediment concentration. Discrete samples of highway runoff also will be collected over a range of specific conductance and analyzed for major ions. These data will supplement available composite sample concentration data to relate measurements of specific conductance to concentrations of deicing elements.
Data Analysis, Interpretation, and Publication
1. Estimate concentrations of chloride and sodium from continuous measurements of specific conductance of highway runoff for each test section. Estimate loads and yields of chloride and sodium for each highway test segment.
2. Compare and contrast constituent concentrations from composites samples among sites and to available highway runoff data in New England.
3. Evaluate pavement data in terms of the frequency and occurrence of various pavement conditions (for example, ice and snow) in respect to pavement salt concentrations or chemically active periods.
4. A USGS Scientific Investigations Report will be prepared and published that documents the study data collection and analysis methods and presents the interpreted results
