Abandoned Dump Sites Field Survey Summary

John O'Meara, Jennifer Bokovoy, and Lynn Craig

Miscellaneous Report, August 1994, 11 pages, Order Number: NPS-MM02.00 ***

This report documents field inspections of 18 abandoned dumps located along the Rouge River. The inspections were performed to identify sites suitable for leachate sampling and monitoring, and to estimate the pollutant loadings on a watershed-wide basis. Abandoned dump sites were mapped on USGS 7.5 minute quadrangle maps for incorporation into the Rouge River National Wet Weather Demonstration Project (Rouge Project) GIS database. Sites were chosen based upon proximity to the Rouge River and its tributaries, amount of available information regarding the site and size information available, and discussions with Wayne County Environmental Health Division (WCEHD) officials. Leachate seeps were observed, some of which flowed into the river or its tributaries. Some seeps unearthed wastes and/or eroded portions of the concrete lining in the channelized segments of the river. Gas seeps, stressed vegetation and insufficient fill cover were observed at several sites. The report provides a summary on each site visited. The appendix contains 98 pages of summary tables, maps and field sketches, and field log sheets.

Analysis for Newburgh Lake Sediment Demonstration Activities

Jennifer Bokovoy, and John M. O'Meara

Task Product Memorandum, December 1994, 7 pages, Order Number: NPS-TPM20.00 ***

The effects of different techniques for the collection, treatment, and disposal of contaminated sediment will each have an inherent potential liability associated with them. This is particularly true with the final disposal process. This analysis is based on the assumption that removal and transportation liabilities will be similar regardless of the recommended disposal method. Disposal methods and a summary of the intended demonstration activities for Newburgh Lake are presented in this report.

Contributions to Surface Water Quality of Atmospheric Deposition in Rouge River Watershed

Nicola Pirrone, Gerald Keeler, Thomas B. Brown, and Mark Mikesell

Technical Memorandum, July 1994, 22 pages, Order Number: NPS-TM20.00 ***

Atmospheric deposition of trace contaminants in urban areas is considered the major diffuse source of loading to urban stormwater. Ambient air concentration data collected at several sampling stations in Wayne County were used to assess these trends over the period from 1982 to 1992. Samples were collected at seven sampling stations situated in residential, commercial, and industrial areas of Wayne County. Analyses were performed by the Wayne County Health Department to determine the ambient concentrations of iron, zinc, lead, nickel, chromium, cadmium, beryllium, and mercury. Analysis of the data shows that the overall variations in dry deposition flux of trace metals to the surface are controlled by the dry deposition velocity, a parameter computed by the authors' model. The dry deposition flux for trace metals associated with smaller particles (zinc, lead, nickel, cadmium, beryllium) is significantly lower than the corresponding ambient concentrations. For metals (e.g. iron) associated with larger particles, the flux is greater than the ambient concentration. The historical trends are upward for iron, lead, chromium, and beryllium, and upward for zinc, nickel, and mercury.

Guidelines for Closure of Abandoned Dump Sites

Zachare Ball, Rhonda Berger, Tom Cok, Rose Ellison, Beth Gotthelf, Jon Hansen, Steve Hoin, Joan Lintelman, Mark Mikesell, Dan

Technical Report, November 2004, 311 pages, Order Number: RPO-NPS-TR11 **

Abandoned dump sites have been revealed at numerous locations in the Rouge River Watershed. Many are located in the flood plain of the Rouge River. Therefore, one aspect of the Rouge River National Wet Weather Demonstration Project has been to evaluate the expected loads to the Rouge River from abandoned dump sites located in the watershed and assess potential load reduction from nonpoint source control efforts. This document has been developed to describe a generic process to provide guidance for the investigation and closure of abandoned dump sites with recreational land use. Limited recreational risk-based closures for abandoned dump sites will focus on eliminating or minimizing the pathways for exposure to the public and the environment.

Guidelines for Conducting a Detention Pond Inventory

Amy Whitens and Ashraf Ibrahim

Task Product Memorandum, June 1997, 67 pages, Order Number: RPO-NPS-TPM46 *

This technical memorandum will serve as a guideline for communities to use to conduct a detention pond inventory. The memorandum gives a methodology to follow if a representative sample, instead of a complete inventory, is required. Blank example tables are provided for communities to use when conducting the inventory. The memorandum also addresses the issue of detention pond operation and maintenance. Proper maintenance of a detention pond is necessary for it to operate as designed. The maintenance of ponds includes such items as inspections, routine maintenance, and non-routine maintenance. Design features to be considered in the design which will minimize maintenance costs are also addressed.

Illicit Connection Detection in the Middle 2

Ashraf A. Ibrahim, Chris G. Nepszy, & Dean Tuomari

Task Product Memorandum, August 1998, 36 pages, Order Number: NPS-TPM52.00 **

This docment summarizes the procedures and results obtained from an illicit connection detection program by the Waye County Department of the Environment. The study was performed in the Middle 2 subwatershed of the Rouge River and comprised of two phases. Phase one was conducted in the communities of Westland, Plymouth Township, Canton Township, and the cities of Plymouth and Livonia. Storm sewer maps of each community were obtained and manholes nearest to outfalls were targeted for investigation as it was assumed that if there was a problem in the line that it could be found in the most downstream manhole. For phase two it was decided to try using a new indicator. Several manholes that were previously tested in phase one were selected based on their appearance or their ammonia levels. Ammonia and E. coli bacteria tests were performed at each of the manholes to try and determine some correlation between the three tests.

Newburgh Lake Basis of Design

John O'Meara, Michael Tomlinson, Jim Poppleton, Mark Mikesell, & John Michalski

Technical Report, April 1996, 89 pages, Order Number: NPS-TR09.01 **

Newburgh Lake is an impoundment in the Rouge River Watershed. The lake is located on the Middle Rouge River in the City of Livonia, and is part of the Wayne County Park System's Edward Hines Parkway. Newburgh Lake was created in the early 1900s and sediments have accumulated. Some of these sediments contain toxic pollutants that can result in a human health hazard. The Newburgh Lake Restoration Project has set out to restore the Lake's recreational uses, and address the needs and desires of the public by eliminating these contaminated sediments.

Newburgh Lake Restoration

Project Profile, April 1999, 2 pages, Order Number: NL-00 **

Newburgh Lake had offered recreational opportunities, but this resource suffered from various problems. Since Newburgh Lake was created in the early 1900s, sediments have accumulated. These sediments, some contaminated with pollutants, have significantly degraded the recreational quality of Newburgh Lake. Shallow water depths resulting from the sediment accumulation and nutrient-rich water have led to excessive growth of aquatic plants. Moreover, some of these sediments contain toxic contaminants such as polychlorinated biphenylÂ’s (PCBs) that have entered the food chain and are currently present in the fish. These contaminated fish result in a potential human health hazard associated with fish consumption. To eliminate this possible hazard, it was necessary to remove the contaminated sediments.

Thomas F. Quasebarth, Kelly A. Cave, Richard A. Wagner, Douglas Denison, Mark D. Mikesell, and Amarjit Sidhu

Technical Report, August 1994, 85 pages, Order Number: NPS-TR03.00 ***

This report reviews available existing data developed under local and national NPS programs and identifies data gaps that will be addressed under the Rouge Project. Available data sources include 208 Programs, the Rouge River Remedial Action Plan (RAP), the Nationwide Urban Runoff Program (NURP) and other ongoing nonpoint studies. Data derived from these sources as well as the proposed Rouge Project field investigations will serve as the basis for developing a cost-effective nonpoint source control program that can be implemented watershed-wide. The field investigations will include monitoring programs performed at pilot sites to quantify nonpoint sources of pollution, and water quality improvements that can be achieved by structural and nonstructural BMPs. The field investigations will also serve to establish the relative costs associated with construction and O&M of various prototype BMPs. Literature reviews were conducted of urban storm water sources and controls, and air deposition sources. The report also summarizes significant local and national programs. Contaminated sediments and abandoned dumps affecting the river are presented along with pilot study, field investigation and data analysis plans. Tables and figures are included; an 80 page appendix is also included.

Process for Abandoned Dumps in the Rouge River Watershed

J. Bokovoy, J. O'Meara, E. Anderson, and M. Droze

Miscellaneous Memorandum, January 1996, 20 pages, Order Number: NPS01D-MM01.00

This document looks at how areas within the Rouge River Watershed were filled in under past practices with solid and/or industrial waste. The process document was developed by a joint effort of EPA, MDEQ, and Wayne County, to provide a basic mechanism by which the Rouge River Watershed can be addressed, and provided for an initial attempt at a systematic approach. The document provides a flow chart of steps, some of which include identification record review, site visit/site screening, sampling and standard clean ups. The Process for Evaluating Abandoned Dump Sites document was developed prior to the enactment of Part 201 of the Natural Resources and Environmental Protection Act, 1994, PA451. Based on the changes in Michigan's environmental regulations, the actual process will be revisited and future versions may include several key elements of this original document.

Process for Evaluating Abandoned Dump Sites Field Sampling Plan

Jennifer Bokovoy

Field Sampling Plan, January 1996, 40 pages, Order Number: NPS01D-FSP01.00 **

This Field Sampling Plan (FSP) specifically addresses the quality assurance requirements of the abandoned dump site sampling program to be conducted under the Rouge Project. The sampling program is part of the "Process for Evaluating Abandoned Dump Sites in the Rouge River Watershed." The purpose of the sampling component is to identify probable pollutants existing at the abandoned dump sites and to identify if further investigation at the individual site is needed. Sampling activities to be performed at the individual dump sites may include seepage, groundwater, sediment, instream water or soil sampling. Specific on-site conditions are examined to determine the extent and type of sampling frequency, sampling methods for the various possible media, field documentation requirements, sample designation, and sample handling and shipping.

Sediment Remediation Techniques: Review of Existing References with Application to Newburgh Lake

John M. O'Meara

Task Product Memorandum, December 1994, 7 pages, Order Number: NPS-TPM19.00 ***

The Rouge Project NPS Pollution Control work effort has been exploring different options for remediating Newburgh Lake sediments and restoring the lake's water quality to allow recreational use (e.g., boating, swimming, fishing). Identification of the contaminated sediments and an accurate bathymetric survey were the first two steps taken to develop this program. The next steps require the development of a mechanism for the removal and ultimate disposal of both contaminated and "clean" sediments. This task product memorandum presents a summary of the investigative work performed on Newburgh Lake followed by a brief review of the three main contaminated sediment remediation handbooks published by the United States Army Corps of Engineers (USACOE) and the United States Environmental Protection Agency (EPA). The proposed remediation options for the demonstration activities at Newburgh Lake are also presented. Appendices contain a total of 18 pages.

Significant Components of Urban Pollutant Loads--Crossing the Final Hurdles for Achieving Water Quality Standards

Flora M. McCormack, & James W. Ridgway

Paper, October 1994, 10 pages, Order Number: WEFTEC94-05 **

NPS pollution control has failed to realize the same reductions as point source pollution because a number of impediments remain in the implementation of an effective NPS program. This paper provides a brief summary of past nonpoint studies in southeast Michigan, the impediments which have prevented implementation, and some alternatives for overcoming these obstacles. The impediments identified by the Rouge Project are not technical, but rather institutional. The Rouge Project recognizes that implementation of NPS controls are best handled at the local level but the motivation to local governments, industries, and residents is not sufficient to initiate controls. The Rouge Project will therefore attempt to forge a consensus between the regulators and the public in general to develop a holistic or consensus-based approach to NPS control and pollution prevention.

Strategies to Address On-Site Sewage System Problems

Barry Johnson

Task Product Memorandum, October 1998, 60 pages, Order Number: NPS-TPM54.00 **

Surveys performed by Oakland County and Wayne County Health Departments found failure rates of onsite sewage disposal systems (OSDS) between 21 percent and 52 percent in communities in their counties. The failures of OSDS contributes to nonpoint pollution and has contributed to the failure to meet surface water quality standards. A review of other efforts to address the regular evaluation and maintenance of OSDS was performed. This search revealed five different ways that communities, utilities and private groups had developed approaches to assure that OSDS were reviewed on a regular basis. This material was shared with local health department personnel, and the Rouge Remedial Action Committee, subcommittee on OSDS. These groups developed a model ordinance and a guidance document to address the regular evaluation and maintenance of OSDS. This material has been made available to communities and has been supported for use to comply with the general storm water permit issued by the Michigan Department of Natural Resources. That permit requires that communities minimize seepage of septic systems into the communities storm water drainage system. The model and supporting information provide a method to minimize the seepage of septic systems into storm drains and surface water.

Summary of Waste Disposal Sites

John O'Meara and Dennis Prevo

Technical Memorandum, July 1994, 8 pages, Order Number: NPS-TM11.00 ***

A summary of the initial efforts to collect existing data on waste disposal sites along the Rouge River is presented. Preliminary field investigations were conducted, and a literature and/or file search was performed at WCEHD, Oakland County Health and Planning Divisions, and both the Waste Management and Environmental Response divisions at the MDNR. A total of 112 regulated active and inactive landfills or unregulated dumps were located in Wayne and Oakland counties. The field investigations revealed evidence of exposed waste along the river and its tributaries, leachate seepages, and cuts into the fills by meandering of the river bed. Literature and file searches focused on information for abandoned sites which might indicate potential sources of pollution to the Rouge River. The searches identified data relating ground water quality, monitoring results, flow direction, soil types, drilling activities, site maps, and photographs. It should be noted that information was not available for many of the abandoned sites. Individual site summaries and photographs are included.
