Approaches for Remediation of
Uncontrolled Wood Preserving Sites
(625/7-90/011)
This document provides an overview of the
process of remediation of uncontrolled wood
preserving sites. It is, in part, a distillation of
discussions that took place at a Forum on
Wood Preserving Waste held in San Francisco,
California, in October 1988. Information from
this workshop has been updated to reflect more
recent technological advances.
Two important elements of the wood preserv-
ing remediation process are emphasized in this
document: 1) she specific factors and 2)
multiple technology utilization. Greater
emphasis is placed on the treatment of soils
rather than ground-water treatment and
containment mechanisms.
Radon-Resistant Construction
Techniques for New Residential
Construction: Technical Guidance (6251
2-91/032)
Growing concern about the risks posed by
indoor radon has underscored the need for
dependable radon-resistant residential con-
struction techniques. The U.S. Environmental
Protection Agency has responded to this public
health concern by developing and demonstrat-
ing a variety of methods to reduce radon in
existing houses. Many of these methods could
be applied during construction, involve reduced
labor and financial investments, and provide
greater homeowner satisfaction and safety than
a radon-reduction technique installed after the
home is built and occupied.
Some of the techniques mentioned in this
manual have not been demonstrated fully in
new home construction. However, the soil
ventilation techniques described have been
extensively tested in existing homes and
show good potential for application in new
construction.
This manual provides a basic understand-
ing of the types of products and systems that
are available and being used to reduce radon
concentrations indoors. The reader will be
able to select radon-resistant products and
systems that will be most applicable to a
particular situation. EPA's intent is not to rate
similar products made by different manufac-
turers or to provide a stock radon-resistant
package.
Revised: Handbook: Ground Water -
Volume I: Ground Water and
Contamination (625/6-90/01<6a)
The Ground Water Handbook, originally
published in 1987 as EPA/625/6-87/016, has
been revised and will be available in two
volumes. Volume I, entitled Ground Water
and Contamination is available as EPA/625/6-
90/016a. It will be followed by Volume II,
Methodology. Although extensively revised,
Volume I was obtained from previous
publications, Handbook: Ground Water
(referenced above) and Protection of Public
Water Supplies from Ground-Water Contami-
nation (out of print).
Volume I includes: 1) Basic Geology, 2)
Classification of Ground-Water Regions, 3)
Ground Water-Surface Water Relationship, 4)
Basic Hydrogeology, 5) Ground-Water
Contamination, 6) Ground-Water Investiga-
tions, and 7) Ground-Water Restoration.
Optimizing Water Treatment Plant
Performance Using the Composite
Correction Program Approach (625/6-
91/027)
This handbook is an interim version of a
document for improving the performance of
$^V Punted on Recycled Paper
-------
existing surface water treatment plants to
achieve compliance with the Surface
Water Treatment Rule (SWTR) using
conventional and direct filtration unit
processes. It addresses the turbidity and
disinfection requirements of the SWTR and
presents procedures for assessing a
plant’s ability to achieve the 0.5 NTU
turbidity requirement. Though the hand-
book is not primarily designed to describe
cost saving options or as an alternative to
designing new facilities for expansion
purposes, in some cases the approach
described may result in cost savings and
increased capacity.
In the Composite Correction Program
(CCP) approach, a logical and systematic
evaluation of a water treatment facility is
made to identify the unique combination of
factors limiting performance. Once
elements affecting a plant’s performance
have been identified, a program may be
initiated to address these findings and
assist the community in using its existing
major unit processes to achieve the
desired finished water quality. Twenty-two
programs have been completed to date
and are described in case studies. Many
communities, especially small ones, are
now considering either constructing new
facilities or modifying existing ones to meet
drinking water regulations. The CCP
approach may enable communities to
meet regulatory requirements by imple-
menting changes in their operational,
maintenance or administrative procedures.
Often these operational-type changes will
be less costly and easier to implement
than major capital improvements.
This handbook was prepared by EPA’s
Offices of Drinking Water and Technology
Transfer and Regulatory Support EPA
Region VIII, along with the states of
Kentucky, Montana, Maryland, Ohio,
Pennsylvania, Vermont, West Virginia, and
Wisconsin, assisted in developing the
necessary information for the handbook
and in reviewing draft materials.
Future Technology Transfer
Meetings
Remedial Approaches for Sites with
Contaminated Sediments
Several uncontrolled hazardous waste
sites have contaminated sediment
problems. A number of proven and many
new and unique methods of sampling,
treating, and disposing of dredged
contaminated sediments have been
developed and implemented. This one and
a half-day seminar series presents detailed
information on sediment clean-up stan-
dards and disposal alternatives, with
specific emphasis on treatment technolo-
gies. The series will foscus on the kinds of
small scale contaminant problems found in
streams, lakes, bayous, and rivers, as
opposed to the larger problems found in
harbors. It will also emphasize sediment
removal and treatment methods as
opposed to sediment criteria assessment.
The seminar is designed for individuals
with responsibilities for the management of
contaminated sediments.
Seminar attendees will be provided a
handbook and other related material on
remedial approaches for contaminated
sediments.
Dates and locations of the seminar are
as follows:
June 18-19, 1991 -Atlanta, GA
June 20-21, 1991 - Philadelphia, PA
July 10-11, 1991 - San Francisco, CA
July 30-31, 1991 - Chicago, IL

tion on content, contact Ed Barth at 513-
569-7669 (FIS 684-7669).
Sewer System Infrastructure
Analysis and Rehabilitation
The sewer systems of many municipali-
ties are in need of maintenance/repair/
replacement for one or more of several
reasons:
• Structural damage due to the effects of
corrosion
• Greatly increased flows caused by
infiltration/inflow
• High exfiltration
Municipalities must expend large
amounts of funds to maintain their sewer
systems, often much more than the cost of
associated treatment facilities. They must
use the most effective methods available
to both minimize the amount of money
spent and ensure that their sewer system
remains capable of handling existing and
future loadings.
CERI will conduct a series of 2-day
seminars this summer to disseminate the
latest available methods to: 1) evaluate
the condition of an existing municipal
sewer system and 2) replace or repair
those portions of the sewer system
requiring work. The seminars will incorpo-
rate the latest techniques available to
evaluate and maintain sewer systems. A
new Technology Transfer handbook will
form the basis for the technical content of
the seminars.
The dates and locations of the seminars
are as follows:
July 15-16, 1991 - Baltimore, MD
July 18-19, 1991 - Chicago, IL
Aug. 5-6, 1991 - San Diego, CA
Aug. 8-9, 1991 - New Orleans, LA
Aug. 19-20, 1991 - Seattle, WA
Aug. 22-23, 1991 - San Francisco, CA
Nov. 18-19, 1991 - Boston, MA

Suggested Practices for the Design
and Installation of Ground-Water
Monitoring Wells
This series will assist personnel involved
in the design, construction, and installation
of ground-water monitoring wells. Presen-
tations will focus on state-of-the-art
technology that can be applied in diverse
hydrogeologic situations. Information will
be provided on field-oriented practices to
solve monitoring well construction prob-
lems rather than conceptual or idealized
practices.
Seminar topics will range from initial
planning for a monitoring well to abandon-
ment. Factors influencing monitoring well
design and installation will include:
purpose, location, site hydrogeology,
contaminant characteristics, anthropogenic
activities, and testing equipment that the
well must aocommodate. Other consider-
ations to be discussed include decontami-
nation procedures, recordkeeping from
well installation through sampling to
abandonment, drilling and formation
sampling techniques, method selection,
materials, completion and development,
and maintenance procedures.
Five, two-day seminars will be presented
in the following locations:
Atlanta, GA, July 9-10, 1991
Denver, CO. July 23-24, 1991
Chicago, IL, Aug. 6-7, 1991
Worcester, MA, Aug. 21-22, 1991
Seattle, WA, Sept. 12-13, 1991

Workshops on Risk Assessment,
Communication, and Management
of Drinking Water Contamination
These workshops update, improve
upon, and continue a very successful
program that was started five years ago.
They are typically sponsored by a local
section of the American Waler Works
Association in cooperation with the local
environmental health association and/or
state water supply program, a local
university and EPAs Regional Office and
Offices of Drinking Water and Technology
Transfer and Regulatory Support. The
program provides uniform and consistent
approaches and processes nationwide for
officials involved in determining, communi-
cating about, and managing drinking water
contamination incidents. Lecture topics
include information on health effects of
contaminants, an approach lo risk assess-
ment, risk communication, and abatement
of lead, biological contaminations, particu-
laths, organics, and radon; as well as
corrosion control. Current regulatory
initiatives are discussed along with an
update of the Office of Drinking Waters
Health Advisory Program. Each workshop
attendee participates in a hands-on case
study that illustrates the elements of risk
assessment, communication, and manage-
ment.
Other topics may be included upon
request by a program sponsor; e.g.,
“Recognizing and Controlling Biofilms in
the Distribution System.”
Participants who can benefit from
attending this program include regional,
state, and local drinking water regulatory
personnel who work in the health and
technology areas related to constructing
new or upgrading existing drinking water
treatment facilities or who must respond to
contamination incidents. The program
should also be of interest to consultants
and drinking water utility staff actively
engaged in the design, operation and/or
upgrading of their treatment systems.
Two workshops are presently sched-
uled. The first will be held May 7-9, 1991,
in Alexandria, Louisiana, and includes an
extra day to discuss biofilm control. The
second workshop will be held in conjunc-
tion with the national meeting of the
National Environmental Health Association
(NEHA) in Portland, Oregon, June 22-27,
1991. It will be a two-day post-conference
workshop held June 27-28, 1991.
For registration and content information,
contact Jim Smith at 513-569-7355 (FTS
684-7355).
National Conference on Control of
Lead in Drinking Water
Lead is one of the drinking water
contaminants of special concern to EPA.
The primary source of lead in drinking
water is corrosion of plumbing materials,
such as lead service lines and lead in
solders and fixtures, in water distribution
systems and in houses and larger build-
ings. Virtually all public water systems
serve households with lead solders of
varying ages, and most faucets are made
of materials that can contribute some lead
to drinking water.
The health effects of lead are serious
and can lead to impaired blood formation,
brain damage, increased blood pressure,
premature birth, low birth weight, and
nervous system disorders. Young children
are especially at risk from high levels of
lead in drinking water. In response to these
concerns, EPA has proposed a more
restrictive MCL for lead in drinking water at
the tap. The proposed rule also includes
public notification requirements. Research
has been aimed at determining the best
available technologies for lead control in
drinking water. Questions remain about
how large and small treatment plants can
meet the proposed MCL.
To publicize information on lead control
in drinking water, the American Water
Works Association and EPA’s Offices of
Water and Research and Development will
sponsor a national conference in Chicago,
Illinois, September 24-26, 1991. The
conference will consist of a general
session for 300-500 people, which will
include state and local decision-makers,
water treatment plant personnel, engi-
neers, and consultants.
The meeting will review health concerns
and the extent of the problem; regulatory
issues, including EPA’s proposed MCL for
lead; sampling and analytical protocols
and methods; and potential solutions to the
problem, including short-term control
measures, corrosion control, removal
technologies, and point-of-use/point-of-
entry devices. The final day will be devoted
to case studies that cite success stories at
both large and small drinking water
systems with varying water quality.
For registration and content information,
contact Jim Smith at 513-569-7355 (FTS
684-7355).
AWWA National Meeting and
Convention
The EPA’s Offices of Technology
Transfer and Regulatory Support (OTTRS)
and Drinking Water (ODW) will again
cooperate in an exhibit at the June 23-27,
1991, American Water Works Association
National Meeting in Philadelphia, Pennsyl-
vania. Approximately 11000 state and
utility personnel along with consultants,
manufacturers and academicians attend
this meeting.
As part of the exhibit, OTTRS and ODW
will display and make available to partici-
pants publications pertinent to the
Agency’s Drinking Water Program.
Testing Methods
Demonstrated on Videotapes
The Center for Environmental Research
Information (CERI) in cooperation with
EPA’s Environmental Research Laboratory
in Narragansett, Rhode Island (ERL-
Narragansett), has produced three
videotapes that demonstrate marine and
estuarine toxicity testing methods. The
videotapes are entitled “Sheepshead
Minnow and Inland Silverside Survival and
Growth Toxicity Tests,” “Sperm Cell Test
Using the Sea Urchin Atbaciapunctulata,”
and “Red Algal Sexual Reproduction Test.”
These marine and estuarine toxicity testing
methods developed by ERL-Narragansett
were adapted from similar methods
developed for freshwater by EPA’s
Environmental Research Laboratory in
Duluth, Minnesota.
The testing procedures demonstrated in
these videotapes measure the effects of
complex marine and estuarine effluents on
the larval survival and growth of the
sheepshead minnow Cyprinodon
variegatus and the inland silverside
Menidia beryllina and on the sexual
reproduction of the marine macroalga
Champia parvula They also estimate the
chronic toxicity of marine and estuarine
effluents and receiving waters on the
gametes of the sea urchin Aibacia
punctulata.
The three videotapes, along with three
supplemental reports and the EPA
methods manual entitled Sljoil-Term
Methods for Estimating the Chronic
Toxicity of Effluents and Receiving Waters
to Marine and Estuarine Organisms are
-------
available only from the National Audiovi-
sual Center. The complete set of video-
tapes and documents can be obtained by
ordering EPA Culturing and Toxicity Test
Methods for Marine and Estuarine Efflu-
ents (Order #A1 8545). The cost of the
complete video package is $85.00. For

New Emission Factors and
Inventories Branch
Developing good estimates for the
source and quantity of a given pollutant
being emitted has always been a key to
determining proper controls and program
emphasis. The Clean Air Act Amendments
increase the need for emission factors and
inventories, both for criteria pollutants and
air toxics. Consequently, a new Emission
Inventory Branch has been established in
the Technical Support Division (TSD) of
the Office of Air Quality Planning and
Sandards (OAQPS) to be the focal point
of these activities. This Branch was formed
from the criteria emission factor and
inventory components of the Monitoring
and Reports Branch of the TSD and the air
toxics emission factor and inventory
components of the Noncriteria Pollutant
Programs Branch of the Air Quality
Management Division. The new Branch is
envisioned to continue the emphasis of its
predecessors on technology transfer and
emission estimation technology improve-
ments.
Some new emission estimation products
that have been released by this Branch
include the revised XATEF and SPECIATE
databases. XATEF presents more than
6000 air toxic emission factors for> 300
toxics and > 350 source categories.
XATEF also presents a qualitative associa-
tion of toxic air pollutant and source
crosswalk (>15,000 pollutant/source
associations). SPECIATE contains >300
volatile organic compounds and >300
particulate matter speciation profiles.
SPECIATE and XATEF require an AT
compatible machine that runs MS-DOS or
PC-DOS 3.0 or later; at least 640 KB of
free RAM; a fixed drive with at least 20 MB
of storage; and a 5-1f4-inch external drive.
The systems are each distributed on one
high density (1.2 MB) 5-1/4-inch diskette
and user’s manuals accompany the
diskettes.
Other emission estimation products from
the Emission Inventory Branch include an
Emissions CD-ROM disk (availability
expected summer 1991) and CHIEF,
included as part of the OAQPS bulletin
board system ((919) 541-5742 for 1200
and 2400 BAUD and (919) 541-5384 for
9600 BAUD]. The Emission CD will contain
XATEF, SPEC 1ATE, AFSEF (database
containing criteria air pollutant emission
factors), the Locating and Estimating Air
Emissions from Sources of (Pollutant)
series of reports, and AP-42. The Clearing-
house for Inventories and Emission
Factors (CHIEF) is designed to provide
access to several tools for estimating
emissions of criteria and toxic air pollut-
ants. CHIEF will serve as a central
clearinghouse for the latest information on
emission inventories and emission factors.
The Emissions CD will be released in late
spring of 1991.
For information on inventory procedures,
call (91 9)-541 -0875 and on emission factor
information, call (919)-541-5522. These
numbers are for criteria pollutants and
toxics information, respectively. For further

The Superfund Innovative
Technology Evaluation (SITE)
Program
The Supertund Innovative Technology
Evaluation (SITE) Program has as its
major thrust the documentation of reliable
performance, engineering, and cost
information for innovative alternative
technologies so that they are developed,
demonstrated and made commercially
available for the permanent cleanup of
Superfund sites. The need for more long-
term, permanent treatment solutions as
alternatives to land disposal has been
stressed by recent legislation such as the
Hazardous and Solid Waste Amendments
of the Resource Conservation and
Recovery Act (RCRA) as welt as the
Superfund Amendments and
Reauthorization Act (SARA) of 1986. The
SITE Program resulted from enactment of
SARA.
Now in its sixth year of demonstrating
technologies applicable to Superfund sites,
the Demonstration Program is working with
52 developers conducting 55 projects.
Demonstration projects identify limitations
of the technology, applicable wastes and
waste media, potential operating prob-
lems, and the approximate cost of
applying the technology.
Over the past year, four demonstrations
were completed in the following technol-
ogy areas:
1. Microfiltration Technology, DuPont &
Company and the Oberlin Filter
Company.
2. Excavation Techniques and Foam
Suppression Methods, USEPA
Region 9.
3. Integrated Vapor Extraction and Steam
Vacuum Stripping, AWD Technolo-
gies, Inc.
4. Solidification/Stabilization with Silicate
Compounds, Silicate Technology
Corporation.
Upcoming demonstrations will indude
the Flame Reactor Process with
Horsehead Resource Development
Company, Inc., Extraction of Oily Waste
by Dehydro-Tech Corporation, and
Precipitation, Microfiftration and Sludge
Dewatering with EPOC Water, Inc.
The Emerging Technologies Program.
part of the overall SITE Program being
implemented by the Risk Reduction
Engineering Laboratory (RREL) in
Cincinnati, provides a framework for
encouraging and testing pilot-scale
technologies that have been proven at
bench-scale but are not ready for field
evaluation. Under this program, EPA is
able to provide funding to developers
through a competitive cooperative
agreement process to help support pilot-
scale equipment development and testing.
Cost sharing by EPA and the technology
developer is an important aspect of the
cooperative agreement which is intended
to foster the commercialization of addi-
tional technologies having application to
the deanup of hazardous waste sites.
Of the 31 projects currently in the
program, seven have completed their
work efforts. Several of the developers
are moving into the Demonstration
Program to continue field evaluation of
their technologies.
A complete description of the SITE
Program and its projects is available in
the “Technology Profiles,” EPA/540/5-90 1
