RESEARCH REPORTING SERIES
Research reports of the Office of Research and Development, U.S. Environmental
Protection Agency, have been grouped into nine series. These nine broad cate-
gories were established to facilitate further development and application of en-
vironmental technology. Elimination of traditional grouping was consciously
planned to foster technology transfer and a maximum interface in related fields.
The nine series are:
1. Environmental Health Effects Research
2. Environmental Protection Technology
3. Ecological Research
4. Environmental Monitoring
5. Socioeconomic Environmental Studies
6. Scientific and Technical Assessment Reports (STAR)
7. Interagency Energy-Environment Research and Development
8. "Special" Reports
9. Miscellaneous Reports
This report has been assigned to the ENVIRONMENTAL PROTECTION TECH-
NOLOGY series. This series describes research performed to develop and dem-
onstrate instrumentation, equipment, and methodology to repair or prevent en-
vironmental degradation from point and non-point sources of pollution. This work
provides the new or improved technology required for the control and treatment
of pollution sources to meet environmental quality standards.

FOREWORD
The Environmental Protection Agency was established to coordinate
administration of the major Federal programs designed to protect the
quality of our environment.
An important part of the agency's effort involves the search for
information about environmental problems, management techniques and new
technologies through which optimum use of the nation's land and water
resources can be assured and the threat pollution poses to the welfare
of the American people can be minimized.
EPA's Office of Research and Development conducts this search
through a nationwide network of research facilities.
As one of these facilities, the Robert S. Kerr Environmental
Research Laboratory is responsible for the management of programs to:
(a) investigate the nature, transport, fate and management of pollutants
in groundwater; (b) develop and demonstrate methods for treating waste-
waters with soil and other natural systems; (c) develop and demonstrate
pollution control technologies for irrigation return flows; (d) develop
and demonstrate pollution control technologies for animal production
wastes; (e) develop and demonstrate technologies to prevent, control or
abate pollution from the petroleum refining and petrochemical industries;
and (f) develop and demonstrate technologies to manage pollution resulting
from combinations of industrial wastewaters or industrial/municipal
wastewaters.
This report contributes to the knowledge essential if the EPA is to
meet the requirements of environmental laws that it establish and enforce
pollution control standards which are reasonable, cost effective and
provide adequate protection for the American public.

ABSTRACT
The planning, design, and operation of land-based wastewater management
systems can be dependent on knowledge of the amount of precipitation which
falls during the operating season. This is particularly true for those cases where
soils with low permeability limit the hydraulic load. Precipitation probabilities
for selected periods at 93 weather stations have been compiled to assist planners,
designers, and others having a need for this type of information. The 93 stations
selected represent a cross section of the differing precipitation patterns across
the United States.

SECTION 1
INTRODUCTION
People involved in the planning, design, and operation of land-based systems
for management of wastewaters need methodology to assess the influence of climatic
factors on off-season storage and operating season hydraulic loading. Whiting (1,2)
has developed computer programs to project off-season storage needs from weather
station data for temperature, precipitation, soil moisture, and snow-cover. These
programs do not provide the methodology for assessing the influence of precipitation
on the determination of hydraulic loading for the operating season. While the oper-
ating season precipitation has little consequence for rapid-infiltration or overland-
flow systems, it can be an important factor in the determination of hydraulic loading
for slow-rate (irrigation type) systems. The relative importance of operating season
precipitation is, of course, greatest for those situations where the ratio of operating
season precipitation to operating season evaportranspiration is comparatively high
and site soils limit the hydraulic load to comparatively low values.
The purpose of this report is to supplement the previously developed computer
programs for estimating off-season storage with a method for assessing the influence
of operating season precipitation on the long term performance of a project. The
information in this report will have its greatest utility for those considering the
design of slow-rate (irrigation type) systems on low permeability soils in regions
with moderate to high operating season precipitation.
The data source is monthly and annual precipitation totals from either the Local
Climatological Data (LCD) tables, or from similar data from cooperative stations in
the 1941-70 normals tape file. As a rule, 30 to 40 years of record are processed and
the period for each station is shown in the table headings.
The gamma distribution function (3) may be used as a model for many sets of
data. This report uses the computer program for this function to provide an analyti-
cal solution to several sets of precipitation data. Precipitation probabilities are
provided for stations in different climatic regimes for up to three time periods: April-
September, October-March, and annual (January-December). The table gives
probabilities of exceeding or not exceeding arbitrary amounts, as well as the amounts
exceeded or not exceeded for arbitrary probabilities. The tables in this report
contain only the columns identified below:
SELECTED Fifty-two or less arbitrarily selected cumulative theoretical
PROB probability values. A program option permits change in these,
VALUES but allows for no more than 52.
-------
SELECTED Cumulative values of the distribution corresponding respec-
QUANTILE tively to the selected probability values. Beta is the scale
B=BETA parameter and is used to transform the standardized distribu-
tion to the actual distribution.
SELECTED Arbitrarily selected cumulative amounts. The maximum number
QUANTITY of amounts is 52. A program option permits change in amounts
LEVELS and also provides for the amounts to be scaled in terms of the
mean of the non-zero amounts.
EXC PRB Probabilities of exceeding the arbitrarily selected cumulative
FOR amounts shown. This is the mixed distribution.
PCP LVL
Two maps (Eastern and Western U.S.) (Appendix A) are included that show the
normal monthly precipitation in inches. Although the maps are based on 1931-60 data
and the monthly amounts may differ slightly from the 1941-70 period, the month-to-
month distribution is about the same regardless of the normal period. The purpose
of these maps is simply to illustrate the different rainfall regimes in various regions.
-------
SECTION 2
CONCLUSION
It is a rather simple matter to determine the probability of exceeding arbitrarily
selected cumulative precipitation amounts for varying seasonal periods from existing
data tapes at NCC-EDS-NOAA, Asheville, NC 28801. Such determinations provide
a convenient and consistent methodology for assessing the probable influence
of operating season precipitation on the long-term performance of some land-based
systems for wastewater management.

SECTION 3
USE OF TABLES
The station list and tables are presented in Appendix B. The stations are
listed alphabetically by state with the page number for the station tables. For
example, Little Rock, AR tables are on page 14, showing three tables for the
Little Rock station covering April thru September and October thru March periods
as well as the annual record.
The 1941-70 normals for each period are given in the heading of the tables
which cover the 1937 thru 1975 or 1976 period of record for the probability determi-
nations . The April-September table will serve to explain the use of the tables.
The fifth line in the table shows a selected probability of 0.90 in column 1. Combined
with the 32.718 inches for precipitation in column 2, this indicates that the return
period of 32.7 inches of precipitation from April thru September is once in 10
years. Columns 3 and 4 are similar but in these columns the quantity of precipita-
tion is selected and the probability is determined. Continuing across line 5,
the selected precipitation amount in column 3 is 21.591 inches and the calculated
probability is 0.617 which indicates that this amount of rainfall will be exceeded,
on the average, in 6 out of every 10 years. Using columns 3 and 4 on line 6
shows that the distribution is slightly askew. The normal precipitation of 23.99
inches computes to a probability of 0.468 rather than the 0.50 probability for
a precisely Gaussian distribution.
As indicated in the description of column headings similar runs can be made
for a variety of arbitrarily selected probabilities or cumulative rainfall amounts.

16. ABSTRACT
The planning, design, and operation of land-based wastewater management sys-
tems can be dependent on knowledge of the amount of precipitation which falls during
the operating season. This is particularly true for those cases where soils with low
permeability limit the hydraulic load. Precipitation probabilities for selected
periods at 93 weather stations have been compiled to assist planners, designers,
and others having a need for this type of information. The 93 stations selected re-
present a cross section of the differing precipitation patterns across the United
States.
