3.    PROJECT DESCRIPTION
      The National Pesticide Survey (NFS) is a high priority undertaking to determine the degree to which
pesticides are present in the nation's drinking water supply.  It is jointly funded by the U.S.  Environmental
Protection Agency (EPA), Office of Drinking Water (OD W) and Office of Pesticide Programs (OPP).  During
the Survey,  well water samples will  be analyzed for the presence of nitrate and  about  120 pesticides,
degradation  products, and metabolites in approximately 1,350 drinking water wells nationally.  The Survey is
based upon  a first-stage statistical design for sample well selection categorizing sites in  two key areas:  agri-
cultural pesticide usage levels and ground-water vulnerability.
      By virtue of the statistical design, the Survey will facilitate  evaluation of associations among pesticide
concentrations in drinking water wells, patterns of pesticide use, and ground-water vulnerability. Ground-water
vulnerability, for the purpose of the Survey, is determined on the basis of the vulnerability score as defined
by the DRASTIC system  developed by the National Water Well Association (NWWA) for the EPA.
      This Quality Assurance Project Plan (QAPjP) addresses the activities  related to assigning DRASTIC^
vulnerability scores at the subcounty level and  developing second-stage sampling units based on cropping
patterns and vulnerability scores within designated counties selected for the NPS.  Domestic well survey
counties for  the NPS were randomly selected based on their overall relative index of agricultural pesticide use
and ground-water vulnerability. A  12 stratum matrix was developed for the selection of the counties.  These
stratum were developed from three ground-water vulnerability index values (e.g., high, moderate, low) and four
pesticide use index values (e.g., high, moderate, low, and uncommon).  Individual steps in DRASTIC mapping
are illustrated in Exhibit  3-1.  Exhibit 3-2 illustrates the sequence of events for  the construction of second-
Mage  sampling units.  As  is evident from the steps  involved, specific activities will include data collection,
mapping,  and digitization, but no direct measurements will  be made.  The  Standard Operating Procedures
(SOPs) for DRASTIC mapping activities are addressed in Appendix  A and the  SOPs for second-stage unit
construction are addressed in Appendix B.  Appendices C and D present the SOPs for coding the Second-
Stage County Agent Questionnaire and the data entry of completed questionnaires, respectively.
      The objective of the DRASTIC mapping is to subdivide each Survey county into regions with common
levels of ground-water vulnerability.  This vulnerability to ground-water contamination from pesticides is a
function of hydrogeologic conditions. The approach selected to achieve this objective involves characterization
of seven  key hydrogeologic  parameters (i.e.  depth to water, net recharge rate, aquifer media, soil media.
topography,  impact of the vadose zone, and  hydraulic conductivity) for the county grouping of subregions
within the county,  quantification of the area encompassed by each level of vulnerability, and assignment of

scores to each region.  The method  to  be  employed includes use of readily available empirical data and
extrapolation of probable parameter values from generic descriptions  of DRASTIC subregion type settings.
      The construction of second-stage sampling units based on cropping and vulnerability will be earned out
in two phases.  In the first phase, interviews with county  agricultural agents (Attachment 1) are conducted to
classify quadrants (USGS 7.5-minute quadrangle maps)  of each of the 90 Survey counties into one of three
agriculture cropping categories.  In general, the three agriculture cropping categories are: (1) more than 50
percent of the area  is cropped; (2) 25 to 50 percent of the area is cropped; and (3) 25 percent or less of the
area identified is cropped (see SOP B for complete second-stage cropping category definitions). In the second
phase, the total area of the county will be partitioned into two strata using ground-water vulnerability and
cropping scores for each quadrant.  Cropping category maps will be combined with DRASTIC vulnerability
maps to  determine  the two strata.  One stratum will contain the  more heavily cropped and more vulnerable
part of the county, and the remainder of the county will be designated to the second stratum. These composite
maps showing the cropped and vulnerable areas of each county will be  used to identify households with wells
that reside in cropped and vulnerable areas of each county.
      This QAPjP  for the Hydrogeologic Group and second-stage stratification team discusses the specific
procedures for assuring  that the data  quality goals of  the NFS are met.  The  QAPjP entails  six specific
features; each  of these elements  is described in detail throughout this  report:
      1)    use of  standard operating procedures (SOP);
      2)    staff training in the  SOP;
      3)    calibration of staff against outside standards;
      4)    internal consistency checks:
      5)    expert  evaluation; and
      6)    comparison  to external data  sources.
      Exhibit  3-3 shows  how second-stage activities fit  in the overall domestic well  selection process. As
shown in this exhibit data entry of completed Second-Stage County Agent Questionnaires is independent of
determining "cropped and vulnerable" subregions  for  oversampling  wells  as part of the Survey design.
Completed second-stage  cropped and vulnerable maps  are produced  by ICF and submitted to  Westat for
selecting homeowners with wells as part of random digit dialing activities. (Additional procedures on selecting
wells is provided in the NPS Survey Statistics. Data Collection and Processing Quality Assurance Project Plan.)

4.     PROJECT ORGANIZATION AND RESPONSIBILITIES
      The organization of the Survey is provided in the overall Quality Assurance Program  Plan  (QAPP).
Exhibit 4-1 shows the position of the Hydrogeological Group and Second-Stage Stratification Team within the
overall project organization.  The ICF Project Director is Harold Lester.  Activities undertaken to implement
and conduct the NPS will be managed under five groups. These groups  include the Survey Statistics Group,
Well Sampling, Data Collection and Processing Group, Communications Group, Report Writing Group, and
Hydrogeologic Group.-'
      Activities addressed in this plan are the primary responsibility of the hydrogeologic group and second-
stage  stratification  team which is organized  as presented in Exhibit  4-2.   The hydrogeologic  group is
responsible for performing DRASTIC mapping activities by subdividing each Survey county into regions with
common levels of  ground-water  vulnerability.  The second-stage  stratification  team is responsible  for
conducting county agricultural agent  interviews to determine the cropping and pesticide use patterns within
each of the Survey counties.   The second-stage stratification team is tasked with the responsibility  for
developing county composite maps which show the more  cropped and ground-water vulnerable regions of each
of the counties for selecting  households with wells.
      ICF's Quality Assurance Officer (QAO), Gary McKown, will manage  the overall quality assurance
activities,  monitor  performance by the task Quality Assurance Coordinator (QAC), review  QAC reports.
request  audits, and inform the Project Director of any problems.  Project  group managers will perform  file
reviews  for every county reviewing all supporting documentation, calculations, assumptions, and completed
work. Random audits will be performed by the second-stage Team Leader on an as  needed basis to ensure
compliance with the standard  operating procedures.  The  QAO will also facilitate resolution of problems
identified during audits.
      The QAC for the hydrogeologic group and second-stage  stratification team will be Charles  Miller  He
will be responsible for implementing  this QAPjP.  As QAC, he has several responsibilities:
      •     Maintain copies of all protocols, methods, SOPs,  QAPjPs, and other documents relevant
            to the activities  under their jurisdiction for the Survey.
      •     Review activities under his jurisdiction and maintain written and properly signed  records
            of each review.   Review documentation will include the date  of the review,  activity
            reviewed, findings and problems, action recommended and  taken  to  resolve  existing
            problems, and any scheduled dates  for additional reviews. Any significant problems found
            during a review  that are  likely to affect the integrity of the Survey will be brought to the
            attention of the project QAO immediately.
      •     Submit to the QAO written monthly program reports noting any problems and corrective
            action taken.
    -  Detailed explanations of the responsibilities for each group are presented in the QAP|Ps.

5.     SELECTION OF RURAL DOMESTIC WELL COUNTIES
      5.1    Selection of First-Stage Counties
      The  NFS  used  a process known as stratification in selecting  the subsets of rural domestic wells for
sampling.   In general, stratified designs are used to improve the accuracy of the estimates by controlling the
distribution of the sample of the population from which data will  be  collected.  The selection of the samples
of the population of rural domestic wells took place in stages, with additional selection criteria at each stage.
The resulting final samples of the population of rural domestic wells were controlled for two specific criteria:
pesticide use and ground-water vulnerability in the county or subcounty area in which the wells  to be sampled
were located.
      Each of the 3,137 counties or county equivalents in the U.S. (which were determined to be conveniently-
sized units  for constructing the first-stage sampling frame) was categorized by pesticide use and ground-water
vulnerability. The first-stage sampling frame was stratified in this  manner  to ensure that samples were taken
from wells  located in areas with different levels of pesticide use and  ground-water vulnerability.
      In 1984 when the Survey design was begun, only limited data  were available on pesticide use. Originally,
all  types of pesticide use  - agricultural,  home and  garden, industrial, nghts-of-way,  commercial,  and
government - were considered as stratification criteria. Because agricultural use of pesticides was significantly
higher than other uses,  agricultural pesticides has been found in ground water, and data on agricultural
pesticide use were better than for other categories of use, agricultural pesticide use was chosen as one of the
stratification criteria.
      EPA developed county-level  pesticide use  estimates for   each county,  based on  1982 Census of
Agriculture information  for  crop  acreages and on private marketing data (provided by Doane Marketing
Research, Inc.) for pesticides.  Total acreage using 63 specific  chemicals  was calculated for 28 crops.   The
acreage to  which a specific chemical was applied  in a county was  estimated; acreages for all chemicals were
summed, and the total expressed as a percentage  of the total area of the county.  Agricultural pesticide use
was described as high,  medium, low, or uncommon, based on the  following criteria:
      •     High Pesticide Use. Agricultural pesticides applied  to the equivalent of 75 percent or more
            of the total county area;
      •     Moderate Pesticide Use. Agricultural pesticides applied  to the equivalent of between 30
            percent and 74 percent of the total county area;
      •     Low Pesticide Use. Agricultural pesticides applied  to the equivalent of between 5 percent
            and 29 percent of the total  county area; and
      •     Uncommon Pesticide  Use.  Agricultural pesticides  applied to the equivalent of less than
            5 percent  of the total  county area.
      In order  to examine any relationships  between  levels  of  pesticides and nitrate  and hydrogeologic
characteristics conducive to ground-water contamination, NFS developed a system for identifying a variety of
hydrogeologic  conditions and  classifying them  into areas of relatively  greater  or lesser  eround-water

vulnerability on a county-wide basis lor the purpose of sample stratification.  One of the goals of the Survey
was to test this system and determine if it functioned as a useful sorting technique.
      The Agricultural DRASTIC classification system,  one variation of an indexed scoring system that had
already been developed by  the National Water Well Association, was modified for use in the Survey by
Research  Triangle Institute.  DRASTIC is an acronym for a ranking system  for evaluating the vulnerability
of aquifers to pollution  beneath a particular land area.  It is derived from  the  seven hydrologic factors
considered in  the  ranking system:  depth of water, recharge (net), aquifer  media, soil media, topography
(slope), impact of vadose  zone, and conductivity (hydraulic) of the aquifer.  Another proposed classification
system, the Great Soil  Groups, was not chosen because its  component factors apply only to the top 30 inches
of soil. Site-specific classification systems were precluded for a large-scale national survey such as NFS because
of the large amounts of data such systems require. Design of an entirely new system for use by the Survey was
precluded by the cost and time that would have been needed to develop it.
      To  represent relative ground-water vulnerability, a county-level DRASTIC hazard  index was developed
for  each of the 3,137  U.S.  counties,  based  on a number of information sources and the experience and
judgment  of hydrogeologists familiar with particular regions.  The sources of information included:
      •     U.S. Geologic Survey (USGS) 1.5 minute quadrangle maps (or 15 minute quadrangle maps
            where 7.5 minute maps were not available);
      •     USGS Geologic Maps and USGS Groundwater Maps (where available);
      •     U.S. Department of Agriculture, Soil Conservation Service Soil  Survey Maps; and
      •     Materials  from State  geologic surveys. Departments of Water  and Natural Resources.
            Departments of Environmental  Protection,  regional  planning  authorities, county and
            regional water supply agencies, private water supply firms, hydrogeologic and engineering
            firms, professional associations, and local colleges and universities.
      These DRASTIC scores were used to divide counties into areas of relatively high, moderate, and low
ground-water vulnerability, as  follows:
      •     High.  County-level DRASTIC score that identifies the most highly vulnerable 25 percent
            of households with wells within each of the pesticide use strata.
      •     Moderate.  County-level  DRASTIC score that  identifies  the most highly  vulnerable 50
            percent of households with wells within each  of the pesticide use strata.
      •     Low.  Remainder of  the  area frame (i.e.,  counties  with  the lowest  DRASTIC scores
            identifying 25 percent of households with wells within each of the pesticide use strata).
Thus, the  DRASTIC scores, together with the pesticide use criteria, result in a matrix of 12 strata. The straia.
and their associated DRASTIC scores, are described in Exhibit 5-1. From each of these 12 strata a statistically
specified number of counties were selected at random from each strata for a total of 90 counties as the primary
sampling unit  in which to randomly select wells (Exhibit 5-2).

      5.2    Pilot Study
      In March 1987, EPA launched a pilot study to field test the major components of the Survey and to
provide an opportunity for any necessary revisions, or modifications before implementing the full Survey.-'
Between March and August, the pilot study for the NPS was conducted in six counties in three States:  Kern
County, California; Ventura County, California; Le Sueur County, Minnesota, Clay County, Minnesota; George
County, Mississippi; and Clarke County, Mississippi.  As a result of the pilot study, recommendations were
made for changes in hydrogeologic characterization and the selection of households to participate in the full
Survey. These recommendations were implemented as part of hydrogeologic characterization and second-stage
stratification activities for  the full Survey.

6.    QUALITY ASSURANCE OBJECTIVES FOR MEASUREMENT DATA
      The  primary objective  for hydrogeologic characterization and second-stage stratification mapping
activities is to construct a sampling frame to identify private water wells supplying occupied housing units
located  in rural areas of the U.S., except government reservations.  Second-Stage maps  were produced to
increase the probability of randomly selecting rural domestic wells in geographic areas that have high pesticide
usage and ground-water vulnerability.
      Accuracy.  Objective is to construct a  sampling frame to  identify a cropped and vulnerable domain
(population of interest)  as small as 0.25%. This is achieved by mapping discrete areas as  small as 100 acres
and using data from local sources.  All data collection involves retrieval of published information  or primary
data from local sources such as geological surveys and county agricultural extension agents.  A maximum labor
expenditure of eight hours per county will be allowed for data retrieval.
      Precision. Objective is to have less than 10% variation between mapping personnel; achieved through
a certification exercise.
      Completeness.  All counties selected for the domestic well survey will  be  mapped, with the exception
of six  counties which were mapped by Research Triangle  Institute as part of  the Pilot Survey.

7.     DATA REDUCTION AND REPORTING
      No  parameters will  be  measured or raw data collected during conduct  of the hydrogeologic charac-
terization  and second-stage stratification tasks.  Data collection will focus on use of published information or
information provided by local experts. .As a consequence, no data reduction or reporting will be performed
on measurement parameters.  Hence, this section of the QAPjP is not required.  Related quality assurance
requirements for the DRASTIC mapping activity are addressed in Appendix A, Standard Operating Procedures
for DRASTIC Mapping Activities. Second-stage stratification activity related quality assurance requirements
are  addressed in Appendix B, Standard Operating  Procedures for Construction of  Second-Stage Sampling
Units:  Cropped and Vulnerable. Data reporting for these activities will consist of two color-coded maps. The
first  map  will present weighted average  DRASTIC hazard  index range scores with the  percent land area
covered by each index range.  The second map will show the cropped and vulnerable and non-cropped and
vulnerable regions of the county.  The Sampling Unit map will be delivered to the Survey Statistics Group
showing identifiable boundary regions of the  cropped and vulnerable regions of the county.
      Data coding and key entry requirements for reporting responses to the County Agent Questionnaire are
presented  in Appendicies C and D. Data reporting of completed County Agent Questionnaires will be used
during data analysis to try  and explain the overall well sampling results.

8.    INTERNAL QUALITY CONTROL CHECKS
      The QAC will perform internal quality assurance checks of completed mapping activities to  ensure
conformance to the standard operating procedures.  He will conduct file checks of all DRASTIC mapping
activities and second-stage stratification tasks to  provide product documentation and ensure consistency
between counties.
      Once  a DRASTIC mapping team is certified, periodic quality assurance checks will be made.  The
quality assurance checks will  consist of observation  of the  mapping  process  to verify  that established
procedures are followed, and inspection of records to verify currency of data (3 times per county).  The QAC
will check the currency and accuracy of solicited hydrogeologic mapping data for the seven DRASTIC factors,
confirm the  DRASTIC region and subregion identifications and compare DRASTIC scores with DRASTIC
default values, and evaluate the completed county digitized DRASTIC map. The completed county DRASTIC
map is evaluated from the information developed on the USGS quadrangle maps in relation to the location
of DRASTIC subregions (i.e., shape and size of subregions and color coding). Should problems be identified
during those reviews, the QAC will help develop appropriate corrective actions.
      The quality assurance provisions for DRASTIC mapping activities include a certification or calibration
exercise.  During this exercise, the mapping staff perform a mapping analysis on Clark County, Mississippi and
their results  are compared to those developed during the NFS pilot study.  The objective of the comparison
is to determine if mapping  staff are sufficiently adept at application of the DRASTIC system.  In part,
DRASTIC mapping is judgmental and this  exercise is to ensure that the teams work would be deemed
acceptable by the DRASTIC system creators, the NWWA.
      For the purposes of this certification/calibration  activity, two quantitative tests will be made:
      1)     an overlay of the map outputs to compare subregion  boundaries; and
      2)     a comparison of vulnerability scores for each subregion.
      Compatibility of results will be judged on the basis of subregion boundary differences and subregion
vulnerability scores each exceeding a level of 10% for each test. With reference to the two tests, certification
is accomplished if:
      1)     overlays reveal that subregion boundaries  leave <.10% of the county area in nonconforming
            subregions; and
      2)     modified vulnerability scores for each subregion are <_10% different than those reported in the
            pilot study.
      The quality assurance provisions for second-stage stratification mapping activities include each member
of the team completing a certification exercise  by producing  a completed cropped and ground-water
vulnerability map on Clarke County, Mississippi. The objective is to determine if procedures can be performed
on a routine basis.
      The QAC will be responsible for performing routine checks of completed work by the Hydrogeologic
Group and second-stage stratification team.  He will be responsible for performing random spot  checks on

identily those individuals responsible for performing corrective action.
      Mr. Miller will ensure that all files pertaining to DRASTIC mapping and second-stage stratification
activities arc properly maintained and indexed for future retrieval.  He will be responsible for ensuring that
all a\ailable data is correctly filed, assumptions and calculations are properly documented, that DRASTIC
mapping procedures are applied using the NWWA's method, and that other individuals  familiar with  the
assignments could duplicate the team's work.
      Exhibit 8-1 provides an overview of the quality control checks for providing DRASTIC maps, second-
stage cropped and vulnerable  maps,  coding County Agent  Questionnaires, and  key entering completed
questionnaires.  Internal quality control checks will be completed by senior members of the Survey staff. Ms.
Lora Johnson, the NFS Quality Assurance Officer will  complete external audits.

9.    SYSTEM AUDITS
      System audits will be conducted during hydrogeologic characterization and second-stage stratification
activities.   These audits will be conducted by the Second-Stage Stratification Team  Leader,  Dr.  Bruce
Rappaport and the NFS QAO, Lora Johnson.  The audit conducted by the Team Leader will be an internal
audit  of conformance to requirements presented  in this QAPjP, whereas the  NFS  QAO will conduct an
independent external audit of all activities. The Team Leader will be responsible to reporting all audit findings
to the NFS Project Director, whereas the NFS QAO will report directly to the EPA  Program Director.
      The audit conducted by Dr. Rappaport will consist of reviewing the files of the completed counties,
selected at random approximately half-way through mapping activities. Dr. Rappaport will check the files to
see if all information can  be easily reproduced from the hydrogeologic mapping activity.  This review will
consist of talking with each team member, asking them to explain their role on  mapping activities and then
jointly going through the files maintained in a central location to see if the final hydrogeologic characterization
assessment can be reproduced.
      To determine the mapping team's conformance to the procedures outlined is this QAPjP, an auditing
form checklist will be completed (Exhibit 9-1).  This form was prepared from the guidelines presented in this
QAPjP. Upon completing the internal audit, Dr.  Rappaport will prepare a summary letter along with the
completed checklists to the QAC, mapping  team, and Project Director recommending improvements where
necessary to document mapping activities. The QAC will be responsible for ensuring that all recommendations
are followed through.

 10.   CORRECTIVE ACTION
      Corrective action measurements for hydrogeologic characterization and second-stage mapping activities
are divided into three categories:
      •     Certification failures;
      •     QC checks; and
      •     Audit deficiencies.
      Certification Failures.  If the assigned DRASTIC mapping staff pass the certification exercise described
in Section 8 of this QAPjP, they will be authorized to proceed with implementation of mapping activities.  If
either subregion boundary or subregion vulnerability score discrepancies are greater than 10%, all DRASTIC
mapping work will be stopped and an analysis made of the differences.  If these differences arise from new,
more accurate data, work  will  be  restarted.   If  the  DRASTIC  mapping differences  reflect  alternate
interpretations of the data, staff will be retrained and a second certification exercise will be conducted using
George County, Mississippi.  Failure to pass certification test will result in replacement of the mapping team.
      QC Checks. The QAC will complete a mapping checklist for hydrogeologic characterization activities
to 1) determine the currency and adequacy of data; 2) verify DRASTIC subregions and scores; and 3) verify
final digitized  maps.  Quality assurance checks to determine the accuracy of the final hydrogeologic  maps will
include:
      •     Verifying road locations against published maps  (e.g., Rand McNally);
      •     Verifying city boundaries and water bodies against published materials; and
      •     Checking zip code boundaries against an available  zip code Atlas.
      Audit Deficiencies. Any mapping deficiencies noted during the QC check  will result in the mapper
correcting any deficiencies. The QAC will discuss each item noted as deficient with the mapping team member
responsible for the county. No maps will be released for Survey  use until all corrections have been made and
a second review is  conducted bv the  QAC.

11.   QUALITY ASSURANCE REPORTS TO MANAGEMENT
      The Hydrogeologic Group QAC, Chuck Miller, will submit monthly progress reports to the Program
Director. Harold Lester and the QAO, Gary McKown. These monthly reports will summarize the past months
activities, deliverables submitted, changes in staff, difficulties encountered and remedial action taken, and work
expected to be completed during the next month's time period. These reports will be submitted no later than
on the third day of the following month.
      This report, while brief in nature, will constitute a formal record of Survey activities.  The report will
be used to track mapping progress and to inform Survey project managers of any task difficulties. The reports
will document problems and resolution of the problems as well as the implementation of this phase of the
Survey. This report will be attached to the National Pesticide Survey Progress Reports  for EPA review. The

1.    TITLE:  DRASTIC Mapping Activities
2.    AREA OF RESPONSIBILITY:  NFS Project
3.    GENERAL REQUIREMENTS:
      a.     Methodology
      Hydrogeologic characterization for the NFS will be performed by the DRASTIC method as described
in DRASTIC: A Standardized System for Evaluatine Ground Water Pollution Potential Using Hvdrogeoloeic
Settings.  The DRASTIC system was developed by the National Water Well Association (NWWA) for the
EPA and is described in detail in Publication EPA-600/2-87-035.  References to DRASTIC in this SOP refer
to the method described in that document.
      All aspects of this SOP require a fundamental understanding and working knowledge of the DRASTIC
method.  Due to the extensive size of  the DRASTIC manual (455 pages), it is  not reproduced in  this SOP.
The SOP is, therefore, a brief description of the procedures to be followed for hydrogeologic characterization
of the counties selected for study in the  NFS. For specific procedures see the DRASTIC manual.
      The purpose of DRASTIC mapping activities is to delineate intra-county ground-water vulnerability
patterns.  The output of the DRASTIC scoring process is a map for each county, delineating the hydrogeologic
settings and their associated vulnerability scores, accompanied by a list of reference materials for each county.
DRASTIC scoring for second-stage stratification is performed using USGS  7.5 minute quadrangle  maps and
geologic maps to identify' boundaries between cropping areas.  The boundaries are drawn in by hand on USGS
maps and quantified using a digitizing  table and computer system with graphics software.
      Time constraints  and the size of  the sample selected  for the NFS necessitate the use of a team to
perform the DRASTIC mapping activities. In order to minimize variability among members of the team as
well as to accommodate reproducibility by future survey participants,  a standard set of procedures has been
devised and formalized.  This procedure will be applied by all participants in  the manner and order prescribed
herein.

4.    PROCEDURE:
      DRASTIC  mapping  activities  for determining  hazard  range  index  values and  plotting DRASTIC
subregion vulnerability areas proceed in a step-by-step fashion as  follows:
      1.     Order county USGS 7.5  minute quadrangle maps;
      2.     Verify that all county quadrangle maps have been received;
      3.     Draw county boundary lines on the appropriate USGS 7.5 minute quadrangle  maps;
      4.     Identify the major DRASTIC region;
      5.     Contact USGS, state geological survey, and other relevant State agencies, the county agricultural
            extension agent, Soil Conservation Service, and other local sources to obtain county specific data
            on the seven factors affecting the DRASTIC score;
      6.     Upon receipt of requested county  data plot  the  depth  to ground water from the well depth
            information, calculate the net recharge, and determine the aquifer media, soil media, topography,
            impact  of vadose zone, and hydraulic conductivity of the  aquifer.  (This is done for as many
            different definable areas  that information is available for within the county);
      7.     Identify the location of the DRASTIC parameters determined in Step 6 on the county USGS 7.5
            minute quadrangle maps;
      8.     Define the DRASTIC subregion boundaries by reviewing  the information from Step 7 written on
            the maps;
      9.     Calculate weighted average DRASTIC scores for each subregion as prescribed in the DRASTIC
            manual and NFS pilot study; and
      10.    Digitize map.
      DRASTIC  mapping activities first begin by ordering  all USGS 7.5  minute quadrangle maps once a
county is assigned to  the DRASTIC mapping team. The mapping team leader, J. J. Dawson is responsible for
ensuring that all maps are received before mapping activities  can start. Prior to assigning a major DRASTIC
region to a county which  will be scored, the county boundary lines are drawn in with a bold marker  to
delineate the county.
      The  major  DRASTIC region assignment will be performed by  Mr. Dawson.  The assignment will  be
accomplished  by  locating  the county boundaries  on a master DRASTIC map which  depicts the major
DRASTIC regions (see NWWA/EPA, p. 15).
      When county borders lie along the boundary of a DRASTIC region, the DRASTIC region descriptions,
the Soil Conservation Service (SCS) county soil survey, and other  references will be reviewed to assure thai
a major candidate region is not eliminated.   When  a decision is not clear cut, additional region designations
will be listed so that  the mapping team  has a broader array of potential subregions to select from. As each

county is classified by the appropriate major DRASTIC regions, it will be assigned to a single member of the
mapping team who will be responsible for integrating the various data inputs and performing the mapping.
      Data will be sought for each county through telephone interviews.  Staff will contact USGS, state
geological surveys, and other relevant State agencies, the county agricultural extension agent, Soil Conservation
Service, and other identified local sources to inquire about depth  to groundwater, average well completion
depth, aquifer media, the presence of confining layers, net recharge, and irrigation practices in each county.
The recharge factor considered for irrigated areas will be handled in accordance with the NWWA's procedures
(see NWWA/EPA, pp. 44-49). The general formula for calculation  of net recharge is: R=(MAP + Irr.) - ET
- RO.  Where R = net recharge, MAP = mean annual precipitation, Irr.  = irrigation applied, ET = potential
evapotranspiration, and RO = estimated runoff.  These data will be recorded on the USGS maps such that
each parameter is placed where the value was measured.
      Dr. Peterson, the team soil scientist/geochemist, will review the SCS county soil survey reports for each
county assigning a DRASTIC soil category for each SCS soil association. The key will be based on matching
soil descriptions.  Information in the SCS soil  surveys is used  to define the soil  and  vadose zone media
according to the  DRASTIC classification system (see NWW A/EPA, pp. 51-56). To classify the soil media
according to the DRASTIC system, several types of information are obtained from the soil surveys.  A list of
the soil associations-^ in a given county is identified, then the soil association descriptions are read to identify
the major soil types. After identifying the major soil  types, the descriptions of the major soil series are read.
Depths, thicknesses, and textures of each  horizon from the major  soil series are then listed.  These depths,
thicknesses, and textures are reviewed and evaluated for their potential  contribution to pesticide movement
or attenuation. The texture and/or horizon dominant in  its effect  on pollution potential is chosen for each
major soil series in an association. The textures chosen from the individual soil series within an association
are compared and evaluated, and a representative texture is chosen from the entire association. This texture
is then correlated with one of the  soil media  in the DRASTIC manual.
      Information found in the soil surveys is also used to help select vadose zone media.  This information
is used to supplement other available information on vadose media. If the surveys contain figures showing
the pattern of soils and the underlying material in the associations within the county, then this  information
can be used to  classify vadose media.  If this information is not available, then area  geology  and soil
descriptions are read to determine the parent material from which the soil  is derived. This parent material
is assumed to be  the underlying vadose media, unless bedrock material is listed with the description.  If the
bedrock material is given, it is chosen as the vadose media.  It is not  possible to determine from the soil survey
information whether the aquifer underlying the vadose zone media is confined or unconfined. Occasionally,
    -' Soil associations are landscapes that  have a  distinctive proportional pattern of soils and, generally,
consist of one or more major soil series and at least one minor soil series.  A series is composed of soils that
have similar profiles.

the rating for the vadose zone media is adjusted to relied information not encompassed within the DRASTIC
methodology.  Moreover, conservative ratings are chosen when in doubt about which of two ratings is the
proper selection.  Data will be recorded on the USGS maps where the information was evaluated.
      A file will be maintained for each county indicating the phone calls made to obtain information, reports
obtained,  and all  assumptions made  to interpret verbal  or written information.  The files  will indicate the
names of the phone  interviewers, the individuals  who  supplied information,  and the date and  time the
information was collected. Files will  be maintained that show all subcounty region vulnerability calculations
for each of the seven DRASTIC factors.
      Data from the SCS survey on soil types and ground water depth will be used to  divide the county into
preliminary zones of like soil characteristics. Soil types, subsoil structure and depth to ground water will be
listed for each subregion.  DRASTIC subregion descriptions will be reviewed and used along with the soil,
subsoil, geology, topography, and depth to ground water to designate DRASTIC  subregions within the county
and locate the boundaries between the subregions (see NWWA/EPA, Section 7, pp. 174-335).  Soil association
boundaries may be found to be coincidental with DRASTIC subregions, but do not in and of themselves define
the boundaries of the DRASTIC subregions.  If no DRASTIC  subregion can be found that matches all the
empirical  data for individual parameters, the subregion  which matches  the most  parameter values will be
selected.  Priority will be given in  the following order:
      1)     surface soil and depth to ground water;
      2)     recharge and subsoil;  and
      3)     topography.
      This priority  reflects  the relative weight of the parameters in  the  development of an agricultural
vulnerability score under DRASTIC.
      When all parameter data are not consistent with the subregion selection (empirical data for one or more
parameters differ from the assigned range of values for the DRASTIC subregion selected) the  DRASTIC score
for that parameter will be adjusted.  In place of the subregion  parameter score, a  value will be assigned on
the basis of the actual empirical data.  The selected DRASTIC subregion  will be used to  assign values to
parameters for which no empirical data are available.  It is anticipated that for many subregions there will be
no  empirical data for depth to groundwater, aquifer media, and hydraulic conductivity.
      Once the subregions have been determined, the boundaries between subregions will be drawn on the
USGS quads along with the subregion designations.  When individual parameters have different values than
the DRASTIC subregion, the vulnerability score modification will be noted.  Weighted averages will be used
for each parameter when empirical data is used  for scoring a particular subregion.  If data  are available on
irrigation practices, irrigated  areas will be sectioned  off and designated with a recharge  score for vulnerability
based on equivalent recharge levels.
      Completed  maps will be sent for internal review and then digitization.  Digitization will be performed
across the county on all subregion boundaries as well as key geographic features.  The latter have been detmed

or other features will he included to allow the reader to orient  himself.  A single composite county map will
be produced from the digitized quads and data prepared on the percentage of each county that falls in each
subregion.  For the purpose of calculating subregion areas, designated metropolitan areas and large lakes will
be excluded during digitization. Scores and parameters along with the subregion boundaries will be put in the
data base to allow retrieval of values by latitude and longitude.
5.    STAFF TRAINING:
      Each member of the mapping team will be trained with the SOP by Jeff Dawson, the Mapping Team
Leader.  Clay County, Minnesota, will be used to demonstrate the procedures through the entire process.
6.    STAFF CERTIFICATION:
      Upon completion of training, each member will be given quads from Clarke County, Mississippi, and
asked to designate the DRASTIC subregions.  Results of these independent designations will be compared to
the map prepared during  the  pilot study. If significant differences are observed, the  rationale behind  the
NWWA version will be reviewed and used  for retraining. Subsequently, the mapper will be retested on other
quads from the county.  If on the second round, there are still significant deficiencies, the mapper will be
replaced. The corrective action aspects of certification are detailed in Section 10.
7.    INTERNAL CONSISTENCY REVIEW:
      All output will be reviewed by the mapping team leader, J. J. Dawson.  He will check quad  interfaces
to ensure a match between subregion boundaries. He will  also compare results between counties  to ensure
consistency between team  members.  If empirical data are  significantly different from those associated with
the DRASTIC designations, additional data sources will be sought (e.g., local  well drillers, state agencies) to
resolve the  inconsistency. The quality assurance coordinator will complete the Quality Assurance Check Sheet
(Exhibn  A-l)  to ensure that  the hydrogeologic  characterization activities are conducted correctly for each
county.
8.    EXTERNAL COMPARISONS:
      Results of the DRASTIC  mapping will be  compared to similar  work by others  at two points in  the
process:
      1)    the assignment of major DRASTIC regions; and
      2)    the quantification of fractions of a county in each subregion.
      At each of these stages, data on county DRASTIC designations contained in  the Graphic  Exposure
Modeling System (GEMS) data base will be compared to the mapping results.  If significant discrepancies  are
noted, additional data will be sought and  the differences resolved.
      Completed  maps and data will be reviewed with county agricultural extension  agents and other local
experts when such experts are identified during the data collection phase.  If discrepancies are identified, a
consensus will  be  reached and scores modified accordingly.

      A file will be prepared and maintained showing the results of each external consistent check for each
county.  Each file will contain the GEMS designations, the selected major DRASTIC regions, the designated
DRASTIC subregions, and comments received back from local experts.  Wherever significant discrepancies
are noted, a narrative will be developed describing how the discrepancy was dealt with. These files will be
available to the QAC at all times. All files will remain  in ICFs Richland, Washington office upon completion
of mapping.
9.     DATA FILE ORGANIZATION
      Data files for each county in the study will be maintained by the hydrogeologic characterization staff
during that phase of the survey.  Files will be kept in a central location in ICF's Richland, Washington office.
      Files will be arranged in alphabetical order by States and by counties within each  State.  Files will
contain a hard  copy of the following materials:
      1.     Reference materials used to develop  the  values  applied to  the seven  factors of  the
            DRASTIC score (where reference materials include published documents, the document
            will  generally  not  be included in  the  file, but  will be noted  in  the  reference and
            bibliography for each county). Reference  materials  may include soil association maps, soil
            evaluations by project staff, and printouts of well location and depth;
      2.     Records of communication from solicitation of data;
      3.     Justification statements for selection of specific hydrogeologic settings (subregions) within
            the county;
      4.     Scoring worksheets  for each subregion in the county;

1.     TITLE:  Construction of Second-Stage Sampling Units:  Cropped and Vulnerable Stratum
2.     AREA OF RESPONSIBILITY:  NFS Project
3.     GENERAL REQUIREMENTS:
      a.     Methodology
      The construction of second-stage sampling units will be carried out in two phases. Data will be collected
by conducting interviews with local county agricultural  extension agents to complete the  County Agent
Questionnaire (Attachment I). Cropped areas are determined from these questionnaires corresponding to each
map quadrant  or region.  In the first phase, 7.5-minute USGS quadrangle maps (quadrants) of each of the 84
survey counties will be assigned a score representing the amount of agricultural activity within the quadrant.
The  scores that are available are 50 percent (or more) cropped (high cropping), 25  to 50 percent  cropped
(moderate cropping), and  25  percent or less (low cropping).  Next, the  total   area of the  county will be
partitioned into  two strata using ground-water vulnerability  and cropping scores for each quadrant.  One
stratum will contain the more  heavily cropped and more vulnerable part of the county, and the remainder of
the county will be designated as the relatively less vulnerable-less cropped stratum. Cropping category maps
are overlaid with DRASTIC mapping scores to determine the cropped and vulnerable regions of the county.
Composite maps showing the relatively more cropped  and more vulnerable areas of the county will be used
to identify households with wells.
      The county agent interview questions focus on the cropping pattern in each quadrant and pesticide usage
in  the area. For this  survey,  farming is  defined as an activity from which Si,000 or more  of agricultural
products were sold or normally would have been sold during a year. Interviews are expected to take from two
to four hours for each of the 84 counties.  Interview length is dependent upon the number of quadrants there
are for a county.  Appointments  will be  made in advance of the interviewer's visit.  In the large counties.
multiple agents may be responsible for the agricultural extension program.  This  may require more  complex
coordination and appointment timing.
      County agent interviews conducted  one growing season earlier than required for second-stage mappme
will require follow-up phone calls with the agents to confirm previously collected information.  County agents
will be telephoned to ensure that the cropping category for each of the quadrants remains accurate.  This
operation will  be overseen by Dr. Rappaport.

4. PROCEDURE:
      In the first phase of second-stage stratification, interviews with county agricultural agents are conducted
to classify quadrants (USGS 7.5 minute  quadrangle maps) into one  of three cropping categories shown in
Exhibit B-l.

Category                            Definition
    1             More than 50 percent of the quadrant is cropped, or, 25 to 50 percent of the quadrant is
                  cropped, but pesticide use in the quadrant is above the county average.*
    2             Between 25 and  50 percent  of  the quadrant is cropped, or, 25 percent or  less of the
                  quadrant is cropped but pesticide use in the quadrant is above the county average.
    3             25 percent or less of the quadrant  is cropped and pesticide use in  the quadrant is about
                  average for the county,  or below  average, or, the percentage of the quadrant that is
                  cropped is unknown.
    Pesticide use in a quadrant is defined as "above county average" if use in that quadrant is high relative to overall use in the county
    For example, in a county with 20 quadrants, if 17 quadrants are non-cropped (no pesticide use) and three quadrants are partially
    cropped with moderate pesticide use, those three quadrants that are cropped would be defined as having pesticide use "above county
    average "
The process begins with obtaining all the USGS quadrangle maps for each county and arranging the maps by
latitude and longitude coordinates. The quadrangle maps are then number coded properly in consecutive
order within a county.  Number codes are listed starting with the first quadrant in the northeast corner of the
county (quadrant 1)  and proceeding west across the county. Quadrants in following rows are numbered in
continuing consecutive number order from east to west. The last map quadrant is located in the far southwest
corner of the county.  The configurations of some counties are such that consecutively numbered maps need
not be adjacent. The quadrant code number assigned to each map is to be written in the upper right hand
corner of the USGS  quadrangle map.
      Coded USGS quadrangle  maps  are  used in  conjunction  with the County Agent Questionnaires
(Attachment 1) for m-person interviews with the local county agricultural extension agents.  These coded maps

will be prepared in advance of the interview.  County agent interviews are conducted b\ project soil scientists,
Drs. S.  Peterson and  B. Rappaport and Mr. Charles  Miller and Project Geologist James Spcrry.  County
extension agents are requested to complete questionnaires for each quadrant map showed to them by one of
the scientists.  In instances where a county is comprised of more than 10 quadrangle maps, extension agents
will be given the opportunity to group quadrants where the cropping and pesticide  use pattern are similar.
Interviewers will provide appropriate guidance to the county agents on  how to make appropriate groupings
of quadrants (e.g., similar farm crops, percent farm land area, percent  farm  land which  receives  pesticide
applications).  To  accommodate changes in the procedure from individual quadrants to groups of quadrants
(regions), questionnaires will be numbered to correspond to the appropriate quadrants.  For example, if the
extension agent groups quadrants 1,  2, 3,  10, 11, and  12 for a county divided into  18 quadrants, then one
questionnaire is used for this grouped region and all the quadrant code  numbers that apply are listed in the
upper right corner of that  questionnaire.
      Questions will be administered by the  team interviewer in accordance with the Question-by-Question
specifications (Attachment B) developed for  the County Agent Questionnaire. When administration of the
questionnaire is considered by the interviewer to be a time burden to the respondent, the interviewer may
combine the answers to  related questions.  For instance, the answer to the time of year when pesticides are
applied (Q.21 may be recorded along with  the list of what  pesticides  have  been used (Q.6) in  the  area
identified on the map. In other instances when deemed necessary by the interviewer to reduce the time burden
placed on the respondent Q.8 may be answered as "see Q.6" when the pesticides recommended (Q.8) are the
same as those known to be used (Q.6).
      After  each county agent  interview session has been completed, interviewers  will be responsible for
identifying the appropriate  cropping category (shown in Exhibit B-l) for each of the quadrants or regions.
The identification  of the correct  cropping category for  a quadrant will be  based primarily on the agent's
response to question 2 in the County Agent Questionnaire. The choice of responses listed  in question 2 are:
(1) more than  50  percent of the area identified is cropped  (e.g., high); (2) 25 to 50 percent of the  area
identified is cropped (e.g., moderate);  (3) 25 percent or less of the area identified is cropped (e.g., low); or (4)
the area identified  is  not known.  When the cropping category is not clearly definable from the response to
question 2, the interviewer will identify the  cropping category by evaluating question  12 which identifies
whether or not  pesticide use in the quadrant or region of quadrants is above or about average for the county.
      The county agent interview team will be responsible for  maintaining a  Field Notebook (3 ring binder)
on each county  agent interview session. This Field  Notebook  will include all County Agent Questionnaires
and additional  notes recorded by the interviewer about county agricultural  practices  that may have been
provided by  the county agent.  After  each county  agent  interview session, the interviewer will  record  the
cropping category  (e.g.,  high, moderate, low) for each quadrant on the Couniy Agent Cropping Category
Record Sheet (Exhibit B-2). When the cropping category is not clearly defined from Question 2 of the County

Auent Questionnaire a justification for the cropping category will he written in the comments section provided
on the County Agent Cropping Category Record Sheet.
      Once cropping categories have been determined, digitization work can proceed on defining relatively
more cropped and more vulnerable regions of the county.  The procedure for producing a digitized  composite
map of cropping categories and DRASTIC vulnerability  proceeds in several steps.  First the relatively low
vulnerable and high and moderately vulnerable areas of the county are mapped by interpretation of  the county
DRASTIC  VARSCORES.  Based on discussions with Jay Lehr, principal author of the DRASTIC system
developed by the National  Water Well Association, relative ground-water, vulnerability can be defined as
shown in Exhibit B-3.  DRASTIC hazard index values < 120  are considered the relatively low vulnerable
regions of the county compared to values _>120 which are  considered the more vulnerable regions.  The more
vulnerable regions of the county are  color coded using the data already stored on a computer disk from the
digitization process of the DRASTIC composite county map (Appendix A).  Using  the cropping category data
recorded on the County Agent Cropping Category Record Sheet a map is made showing the intersection of
the more relatively cropped and more vulnerable regions  of the county.-/
      The step-by-step procedures for digitizing cropped  and vulnerable regions are as follows:
      1.     Identify county to be mapped;
      2.     Create a cropping category data base;
      3.     Digitize cropping categories 1, 2,  and  3 for each USGS quadrant;
      4.     Retrieve DRASTIC VARSCORE data base;
      5.     Retrieve cropping category database;
      6.     Compare  DRASTIC VARSCORES with  cropping categories  by showing the intersection
            of the cropped and vulnerable regions from completed digitized maps;
      7.     Identify subregion county  land  areas where DRASTIC hazard index values of j>180
            intersect cropping land areas of >25%  and DRASTIC hazard index values of _>120
            intersect cropping land areas  of >50%\
      8.     Map the cropped and vulnerable regions defined by the overlaid boundaries using the  pen
            plotter;
      9.     Draw  major  land features for the cropped and vulnerable regions of the county on  the
            map; and
      10.    Deliver county maps identifying cropped  and vulnerable stratum to the Survey Statistics
            Group to  begin identification of households  in  the stratum.
   - Cropped and vulnerable subregion county land areas are where DRASTIC hazard index values of _> 180
intersect cropping land areas of >259f and DRASTIC ha/ard index values of >. 120 intersect cropping  land
areas of >509ฃ.

      Major land features will be provided on the completed maps in the region of cropped and vulnerable
to allow boundary area determinations for third-stage sample allocation. These land features will be digitized
onto the composite county maps and include major cities, rivers, and interstate highways.  This will provide
the cropped and vulnerable regions within each county that will be oversampled using Random Digit Dialing
(RDD). When zip code files are made available, zip code regions will be digitized onto completed second-
stage maps.
5.    STAFF TRAINING:
      Each member of the team will be trained with  the SOP by Bruce Rappaport.  A set of Question-by-
Question Specifications (Attachment II) will be used during the training.
6.    STAFF CERTIFICATION:
      Upon completion of training, each member of the county agent interview team will be reviewed by Dr.
Rappaport for  conformance  to  the SOP.   One member of the interview team will be  evaluated  by Dr.
Rappapon in the field to determine the adequacy of the training program.
7.    INTERNAL CONSISTENCY REVIEW:
      All cropped and vulnerable maps will be reviewed by Chuck Miller, the quality assurance coordinator
(QAC).  He will complete the Quality Assurance Check Sheet (Exhibit B-4) to ensure that the maps arc
produced correctly.
8.    EXTERNAL COMPARISONS:
      Completed  cropped and vulnerability maps will be reviewed by members of the DRASTIC mapping
team.  If discrepancies are identified, a consensus will be reached and categories modified accordingly.
      A file will be prepared and maintained showing  results of each external consistency check for  each
county.  Each file will contain the designated  cropping  regions,  the County Agent Questionnaires, and
comments received back from project reviewers. Wherever significant discrepancies are noted, a narrative will
be developed describing how the inconsistency was dealt with. These files will be available to the QAC ai all
times.

1.    TITLE:   Data Coding for Second-Stage County Agent Questionnaire:  Questions 6, 8, and 21
2.    AREA OF RESPONSIBILITY:   NFS Project
3.    DEFINITIONS:
           Active Ingredient:       constituent  in a  compound responsible for chemical
                                   control.
           Active Ingredient Rate:   measure of the actual chemical killing agent used for
                                   dispensing the pesticide.
           Formulation:            symbolic expression of the dilution or percentage  and
                                   physical state of the active ingredient.
           Mixture:                combination of two  or  more  pesticides  (may  include
                                   formulations) mixed by applicator and applied together to
                                   a specific crop.
           Value:                  numerical quantity of the specified pesticide designated for
                                   land application rate.
           Units:                  ratio of quantity of specified product to the area of land
                                   specified for application.
4.    GENERAL REQUIREMENTS:
      a.    Methodology
      County Agents were interviewed in 84 counties to obtain information on crop types and corresponding
pesticide usage in county quadrants mapped for hydrogeologic characteristics. A County Agent Questionnaire
was completed  for  every  quadrant mapped  in each  county.  Questions 6  and 8  of the  County Agent
Questionnaire requested information on pesticides known to be used (by crop) with the application rate, and
those recommended (by crop) with the recommended application rate, for the years  1984 through 1988.
      Question 21 of the County Agent  Questionnaire requested information concerning  the time of year
pesticides were applied to the major crops farmed in the area. At  the beginning of the County Agent survey,
the County Agent Questionnaire contained only 19 questions (in these Questionnaires, Question 19 requests
information on time of application).  Two questions were added to the original (19 question) Questionnaire
after several County Agent interviews were completed.  The "new" questions were numbered 11 and 12, and
the existing questions 11  through  19 were renumbered accordingly.  The  "new"  question  11  requested
information on the presence of a golf course in the area, and the "new" question 12 requested information on
general pesticide usage in the area (e.g. high or low). County Agent Questionnaires completed prior to the
addition of the "new" questions will be edited and renumbered for key entry following specific procedures

                                                                                   Appendix C
                                                                                   Revision No. 0
                                                                                   Date:  March 29, 1991
                                                                                   Page 2 of 24
identified in this SOP.  In addition, questions 9, 10, and 17 will be edited for key entry. For these questions,
blank spaces in front of numbers will be filled in with zeros to ensure correct key entry of the data.
      Due to the quantity and complexity of the responses to questions 6, 8, and 21  in the County Agent
Questionnaire,  receding the information will be necessary before data entry can be performed.  Because the
data from questions 6, 8, and 21 is interrelated, one coding sheet (Exhibit C-l) has been designed to organize
all responses to those questions.  Codes have  been designated for pesticides (Exhibit C-2), formulations
(Exhibit  C-3), units (Exhibit C-4), and time of application  (Exhibit C-5).
      County Agent Questionnaires are maintained in three-ring binders in  the document control room. For
each county,  a  Questionnaire was completed for every mapped quadrant, in that county.  In some cases,
responses were  the same for two or more quadrants in a county; when this is the case the applicable quadrant
codes will be identified in the top right hand corner of the County Agent Questionnaire introduction page.
One binder will contain every Questionnaire completed for an individual county,  with  the county name
identified on  the outside of the binder.
      Each Questionnaire will be reviewed and responses from questions 6, 8, and 21  receded following the
specific procedures identified in this SOP.
      b.     Materials Required
               i.   County Agent Questionnaire(s)
             ii.   Blue Pencil, Black Felt-tip Pen
             iii.   Data Coding Sheet(s)
             iv.   Q.11/Q.12 Coding Sheet(s)

            viii.   Time of Application Code List
5.     PROCEDURE:
      a.    Preliminary Steps
      1.    Select a county for data coding.  Locate the name of the interviewer for the selected county on
           the "County Agent Cropping Category Record Sheet" (first page in binder).
      2.    Review County Agent Questionnaires to locate responses to questions 6 and  8.  Meet with the
           interviewer, if necessary, to clarify format or any responses that are  unclear at this point.
      3.    Review the first County Agent Questionnaire to locate response to question 21 (19).
      4.    If question 19 is the last question in the Questionnaire, look for an insert with xeroxed questions
           (re: golf course and general pesticide usage in the area).  If an insert is present, make sure it is
           placed in the Questionnaire after the page with  questions  8,9, and 10,  then  number the "golf
           course" question 11, and the "general pesticide usage" question 12 (NOTE: always use a blue

            pencil when making any edits to a Questionnaire).  Then renumber the existing questions 11
            through 19, so they become 13 through 21.
                  If no insert is present in the (19 question) Questionnaire, place an insert page (see Exhibit
            C-6) in the notebook after the page with questions 8,9, and 10, write the date on top of the page,
            and circle each 97.  Then  renumber the existing questions 11 through 19, so they become 13
            through 21.  The existing question 11 directs the respondent to "skip to Q.14" in certain cases.
            In the renumbering process, Q.14 becomes Q.16, so the "skip to" command must be renumbered
            by placing a slash (/) through the 14 and writing 16 next to it.  Continue this process, reviewing
            all Questionnaires in the binder, ensuring that all questionnaires end with question 21.

                                          INSERT PAGE
                  11.   Is there a golf course located in the area identified on the
                       map?

                                                     Question not asked	97
                  12.   Would you say that in this area, pesticide usage is generally
                       higher, lower, or about the same as the rest of the county?
                                                     Question not asked	97
      5.     Review questions 9, 10, and 17.  If 98 is circled for any response to these questions, place a slash
            through the 98 and write 998 in the three blank spaces provided (	).  Place zeros in any
            spaces left blank where 998 does not apply (i.e. if the response is	I, place zeros in the two
            blank spaces before the one). Continue this process, reviewing all questionnaires in the binder,
            to ensure that there are no blank spaces left in any response to questions 9, 10, and 17.
      b.     Data Coding
      Each data coding sheet is a record. A record will be filled out  for each pesticide (or mixture), by crop,
identified in the responses  to questions 6 and 8.  To complete a record, follow steps 1-15 below:
      1.     Select the first County Agent Questionnaire (in the binder) for coding. Use a black felt tip pen
            to fill out the  coding sheets.
      2.     Write the page number in the Page	of	space on the data coding sheet. Initial the
            top right hand corner of the sheet.
      3.     Write the applicable quadrant number(s)  in the space marked Quad:	on the data coding
            sheet.
      4.     Write the State and County in the space provided on the data coding sheet.

5.    For Applies to question 6? answer with:
      "Y" if the information in this record exactly matches that for the response to question 6.
      "N" if the information in this record does not exactly match that for the response to question 6.
6.    For Applies to question 8? answer with:
      "Y" if the information in this record exactly matches that for the response to question 8.
      "N" if the information in this record does not exactly match that for the response to question 8.
7.    For Crop: enter the crop name on the data coding sheet.  If no crop is identified, enter Not
      Specified.
8.    For Pesticide Code: refer to the Pesticide Code List to identify the applicable 4 digit code and
      enter it.  If a code cannot be found, see "code note" below. If the response states that a mixture
      of pesticides is used,  enter 9999 for the pesticide code and use the "specify" field to enter the
      codes for the pesticides constituting the mixture, separating each pesticide code with a comma.
      Before entering 9999, make sure that  the mixture isn't listed  on the Pesticide  Code List.  If a
      specific code is given for a mixture, use it instead of 9999.   In some cases, the interviewer
      responded to  questions  6  and/or  8 by referencing special inserts (xeroxed pages from trade
      manuals, books, etc.).  These special inserts should be reviewed with the interviewer.  When a
      pesticide is selected for data coding from a special insert, the pesticide and all corresponding
      information selected for  data coding should be underlined with blue pencil if it has not already
      been highlighted  by the  interviewer.  If the respondent referenced a special insert for  a crop
      category but did not identify specific pesticides used or recommended, enter 9997 for the pesticide
      code for that crop.
9.    For Pesticide Formulation: if a formulation of the pesticide is identified in the response, refer
      to the  Formulation Code List to  identify the applicable 4 digit code and enter it. If a code
      cannot be found, see "code note" below.  If the 9999 code has  been entered for Pesticide Code:
      do not enter a formulation code (the computer will do it automatically); the "specify" field should
      be used to identify the formulation  codes for each pesticide in the mixture.  In this case (pesticide
      code 9999), each  formulation  code should  be separated with  a comma and listed in the same
      order as the corresponding pesticide codes are listed in the pesticide code "specify" field. If no
      formulation is identified, or if the  pesticide code 9997 has been used, enter a code of 7777.
10.    For Application Rate: enter the numerical value of the land application rate before the hyphen
      on the data coding sheet (if the rate is  a fraction, put a 0 before the decimal  point).  If there is
      no response for the application rate (or if Pesticide Code 9997 has  been entered),  enter a code
      of 7777.7777.   If  the pesticide is a mixture (i.e.  pesticide code  is 9999), do not enter an
      application rate; use the specify field to list the values of the application rates  or ranges for each
      component of the pesticide mixture. Values in the "specify" field should be separated by commas
      and listed in the same order as the corresponding pesticide "specify" field codes  (if only  one

                                                                                   Page 22 of 24
            numerical value is given for the application rate of a mixture, enter that value in the "specify"
            field).  If a range is given for the land application rate, see step 11.  If the response is "see label
            rate" for the application rate, enter a code of 8888.8888.
      11.   If the application rate is given as a range of numbers instead of one value, or as both a value and
            a range, enter the land application rate range, with the low numerical value entered first and the
            high value entered in the space after the hyphen (-). The two values should be identified from
            low to high, separated by the hyphen.
      12.   For Significant Figures: enter the number of significant figures following the decimal point in the
            response to Application Rate: If 7777.7777, 8888.8888, or 9999.9999 have been entered for the
            application rate, enter a code of 4 for significant figures.  If there is more than one application
            rate, enter the greatest number of significant figures.
      13.   For Units: refer to the Units Code List to identify the applicable three digit code for the land
            application rate units and enter it.  If no units are identified, or 1111.1111 has been entered for
            the application rate, enter a units code of 777. If a code cannot be found, see "code note" below.
            If the pesticide code is 9999, do no enter a units code; use the specify field to enter units codes
            separated  by commas and identified in the same order as the corresponding pesticides in the
            Pesticide Code: "specify field".  If "see  label  rate" is entered  for Application Rate (Valuel (i.e.
            a code of 8888.888 is entered), do not enter  a units code.
      14.   For Time of Application: review question 21 to determine  the  time of application for each
            pesticide, refer to the Time of Application Code List to identify the appropriate two digit code,
            and enter it. If a code cannot be found, see "code note" below.  If more than one time of
            application Code applies, enter a 99 and use the specify field to  list the appropriate codes in
            sequence, separated by commas.  If pesticide code 9997 has been entered, enter 42 for the time
            of application code.
      15.   For Applied in 1988 (Y/N)? (and 1987,1986, 1985,1984), review questions 6 and 8 to determine
            which year is applicable.  Enter Y if the record applies to that year or N if it does not. If there
            is no response, enter R.
      Complete steps 1-15 for each pesticide identified in the responses to questions 6 and 8, using a separate
data coding sheet for each pesticide.  When data coding for a Questionnaire is completed, the total number
of pages should be entered in the Page	of	space on each data coding sheet, and the data coding sheets
checked to make sure that they are numbered sequentially and that the pages are in numerical order.
      If an interviewer's handwriting cannot be interpreted or the scientific  information provided  is not
complete, the interviewer will be contacted for assistance.
      When coding is complete for the Questionnaire, select the next Questionnaire in the binder and  follow
steps 1-15, numbering all data coding sheets when finished.  Continue this process until coding is complete
for a county.  In many counties, pesticide data will be the same for more than  one questionnaire. If this is

 the case, the data coding sheets may be xeroxed where applicable, and the information on quadrants and page
 number (see steps 2,3, and 4) changed as necessary.  In several counties, an  extremely large  number of
 pesticides are identified. These counties will be identified by Carol Lindsay, and a special procedure will be
 used for coding as follows:  a set of master coding sheets will be prepared including all pesticides listed for
 the county; the master will be placed with the quad that has the greatest number of crops; after data is  key-
 entered for each questionnaire, including the questionnaire with the master coding sheets, Suha  Biedas will
 copy the relevant crop files into each quadrant as they apply.
      Code Note: If a code cannot be found on the master code list, one may be added in one of the blank
 numbered spaces provided on each code list.   DO NOT CHANGE THE NUMERIC SEQUENCE OF THE
 EXISTING CODES!!
 6. STAFF TRAINING:
      The Lake, IN  County Agent Questionnaire Quadrant 5, and Hancock, IN Quadrant 3 will be coded as
 test cases by Carol Lindsay and Bruce Rappaport.  Each data coder will be trained with the SOP by Carol
 Lindsay or Jim Sperry, coding data from the Lake, IN County Agent Questionnaire Quadrant 5 to learn the
 procedure.
 7.    STAFF CERTIFICATION:
      Upon completion of training,  the coded Questionnaire will  be reviewed by Dr. Rappaport for
 conformance to the SOP. Results will be compared to the test case.  Wsfgnificantly different, the rationale
 will be reviewed with the coder and used for retraining. The  data coder will be retested using the Hancock,
 IN County Agent Questionnaire Quadrant 3.  Results will be compared to the test case, and if they are not
 100% correct, the data coder will be replaced.
 8.    INTERNAL CONSISTENCY  REVIEW:
      Jim Sperry or Carol Lindsay will review 10% of the coded questionnaires for each county to ensure  that
 they are coded correctly.  Dr. Rappaport will review 1% of the reviewed coded questionnaires for each county
 to ensure  consistency. A Quality Assurance Check  Sheet (Exhibit C-7) will be completed for each review
 performed.
 9.    DATA FILE ORGANIZATION:
      County Agent Questionnaires for all quadrants in a county are maintained in a 3-ring binder (one binder
for each county) in the NPS Prep Room.  Individual  counties  will be signed out for coding.  When coding is
complete for a Questionnaire, the coding sheets will be inserted in the 3-ring binder following the page with
Question 21  for that questionnaire.  If all the questionnaires for a county do not fit in one notebook
following data coding for that county, the questionnaires may be split into two or more notebooks per county.

1.     TITLE:  Procedures for Data Entry of Second-stage County Agent Questionnaire
2.     AREA OF RESPONSIBILITY:  NFS  Project
3.     GENERAL REQUIREMENTS:
      A.    Methodology:
      County Agent Questionnaire responses will be entered into NPSIS2 for data analysis.  The County
Agent Questionnaire was administered to county agricultural extension agents in 84 counties in 35 states across
the nation.  Each county agent responded to  questions regarding crop types, pesticide usage, soil textures, crop
management practices, irrigation methods, and conservation measures across the county for which they serve
as Agriculture Extension Agent.  Information gathered in this questionnaire was  initially used to determine
cropping areas within each county for second-stage stratification.  These cropping areas were later overlain
with groundwater-vulnerability information to identify "cropped and vulnerable" areas for oversampling. The
County Agent Questionnaires and other important and related materials gathered during the interviews will
be stored in three-ring binder notebooks and maintained in Document Control.
      The County Agent Questionnaire will be key entered into NPSIS2 by temporary key operators. These
data key entry personnel ("keyers") will report to Ms. Lindsay and Mr.  Sperry for problems involving the data
as recorded in the questionnaire. The keyers will report to Ms. Beidas, the Second-stage Database Manager,
for questions involving the computer program.   Dr. Rappaport will oversee all operations of data entry and
will ultimately be responsible for resolving any questions.
      B.    Equipment and Materials Required:
              i.   Completed County Agent Questionnaire
              ii.   National Pesticide Survey County Agent  Questionnaire Data Entry User Guide
                  (Attachment  III to this QAPjP)
             iii.   Hardware: IBM PC (640K memory)
             iv.   Software: NPSIS County Agent Questionnaire (CAQ) Data Entry System
4.     PROCEDURE:
      A.    Participate in training for data entry of the County Agent Questionnaire conducted by Ms. Beidas
           and Ms. Lindsay.  Read the National Pesticide Survey County Agent  Questionnaire Data Entry
           User Guide.  Refer  to this guide if there is any doubt about the data entry procedures.
      B.    Obtain a County Agent Questionnaire three-ring binder from either Ms. Lindsay or Ms. Beidas.

      C.    Access and manipulate the CAQ Data Entry System to enter and store the coded responses in
            the County Agent Questionnaire as instructed in training and as outlined in  the  National
            Pesticide Survey County Agent Questionnaire Data Entry User Guide.
      D.    Page Ms. Beidas or Ms. Estrada, the NPSIS Database Manager, in order to answer emergency
            questions regarding computer programming problems.-/
5.    STAFF TRAINING:
      Keyers will be trained by Ms. Beidas, the Second-stage Database Manager, according to the procedures
specified in the National Pesticide Survey County Agent Questionnaire Data Entry User Guide.  During
training, each individual responsible for data key entry will be issued this guide for reference during the data
entry process.   No individual will  be allowed access to the CAQ data entry system or issued a Keyer
Identification Number prior to training.
6.    STAFF CERTIFICATION:
      Upon completion of training, each keyer will be continually evaluated by Ms. Suha Beidas through her
review of the "Double Key Comparisons" file.
7.    INTERNAL CONSISTENCY REVIEW:
      Quality assurance/quality control procedures will be implemented in order to ensure that the data are
entered into the system and stored  accurately and consistently and that the integrity of the data is not
compromised during the data entry process. Inherent in the CAQ Data Entry System are numerous controls
to ensure the accurate and consistent entry of data:
      A.    Each keyer will be issued a unique and confidential Keyer Identification Number. This will
            prevent any unauthorized individuals (i.e.,  anyone not  successfully completing training)
            from accessing the system.
      B.    Training will be conducted by one individual, Ms. Suha Beidas, the Database Manager.
            This will ensure consistency in training.
      C.    Each keyer will be issued his/her personal copy of the National Pesticide Survey County
            Agent Questionnaire User Guide upon completion of training for reference during the data
            entry process.  This will ensure that a standard set of procedures is followed during the
            data entry process.
8.    EXTERNAL COMPARISONS:
      All questionnaires will be double key entered, that is,  each questionnaire will be entered once by two
different keyers. The computer is programmed to compare the information entered by the two keyers. Any
discrepancies involving entered information will be resolved by Ms. Linda Prevatte, coder for the County Agent
Questionnaire.  Ms. Prevatte will review the original questionnaire and determine which keyer entered the data
incorrectly.  Daily printouts of the double key entry and validation process are stored in a three-ring binder
   -' Ms. Beidas and Ms. Estrada will wear pagers during business hours to ensure that an expert computer
programmer will be available to respond to emergency programming needs.

Introduction:

The U.S. Environmental  Protection Agency i* conducting a National Pesticide Survey to
obtain information on pesticide contamination in drinking water wells and to leam how the
pesticides in these wells are associated with pesticide usage and groundwater vulnerability.
This questionnaire pertains to the area identified on the map.   For this survey,  farming is
defined  as an activity from which $1,000 or more of agricultural products were sold or
normally would have been sold during a year.

U.S. ENVIRONMENTAL PROTECTION AGENCY

       NATIONAL PESTICIDE SURVEY
      Question by Question Specifications
                  for the
         County Agent Questionnaire
          * * * August 31, 1988 * * *

1.    This questions asks for which crops are grown in the area identified on the map.

     The response can be for a group of maps which  are contiguous to one another.

     Farming of crops on a given map shown  is defined as an activity from  which $1,000
     or more of the crop  was sold or normally would have been sold during a year.

2.    This questions  asks for the percent of  land  area farmed with  the  crops  listed  in
     Question 1.

     Farmed  area  means the  land area  where  the crops  circled  in Questions 1  were
     grown  in the past year.

3.    This question asks  what is  the average surface soil texture of the land  identified on
     the map.

     For the  purposes  of this question,  clay  and clay  loam soils will include silt loam
     soils.

     Silt and silty clay loam soils will  include silt loam soils.

     Sandy  loam will include sandy clay loam and sandy  clay soils.

     Sand will include loamy sand soils.

4.    This question asks  what  is the  average  soil permeability  of the land identified on
     the map.

     Soil  permeability  is the  ease with  which  gases,  liquids,  or  plant  roots penetrate
     through a bulk  mass of soil  or a layer of soil.

     Ask  the respondent to relate the question  to  the  soil profile  and not to  either a
     specific surface  or subsurface soil horizon.

     If asked, "would a  limiting  horizon  such  as a clay pan  be  reason enough to  say very
     slow," answer yes.

5.    This question asks  if  any  pesticides have been used on  the land area on  the  map
     between January 1, 1984 and the  present.

     Pesticides include insecticides, herbicides, fungicides, nematicides, rodenticides, and
     other chemicals except fertilizers.

     Pesticides for this  answer  include  recommendations  made by  the county extension
     office,  forest  service, and  chemicals that you do  not necessarily recommend, but
     know they may be used.

     If no pesticides have  been  used  or the respondent  does  not know  of any  pesticide
     application then skip to Question 7.

6.   This  question  asks the  respondent to  list  the  pesticide  used  on the  land area
     identified on the map,  starting with  1988 and working back to 1984.

     The  questionnaire has two lines for responses  for  each year.  If two pesticides have
     been  used, label the  top  line "1", and  label the second  line "2".  If more  than two
     pesticides have been used  in a year, complete a continuation sheet for the question.

     The  code  for  the brand name  or trade name  (AAtrex)  of  the  pesticide  is the
     preferred  response.   Other  acceptable  responses  include  the active  ingredient
     (atrazine), or type (herbicide).

     If the respondent knows  that no pesticide was used during  the  year, enter "None"
     on the line labeled pesticide.

     If the respondent knows  that a pesticide  was used but  does not  know the name of
     the pesticide used, circle the code 98 for "Don't Know".

     List  the  pounds  per acre per year  of  the pesticide  along with the  formulation.  If
     the response is  in some other unit  of  measure,  such  as  pounds of active  ingredient
     per acre  record the response in the margin.

7.   This question asks if you have made recommendations for pesticide use on the land
     area identified on the map between January 1, 1984 and the present.

     Pesticides include insecticides, herbicides, fungicides,  nematicides, rodenticides, and
     other chemicals except fertilizers.

     Pesticides for this answer  include  only recommendations  that  the respondent has
     personally made as the county agent.

     If no  pesticides  have been  used  or the county agent does not  know  of pesticide
     recommendations they  have made then skip to Question 9.

8.   This question asks the respondent to list the pesticides  for which  they have  made
     recommendations on usage for the  land  area identified  on the map,  starting with
     1988 and working back to 1984.

     The  questionnaire has two lines for responses  for  each year.  If two pesticides have
     been  used, label the  top  line "1"  and  label  the second  line "2".  If more  than two
     pesticides have been used  in a year, complete a continuation sheet for the question.

     The  code  for  the brand name   or  trade  name (AAtrex)  of  the  pesticide  is the
     preferred  response.    Other  acceptable   responses  include  the active  ingredient
     (atrazine), or type (herbicide).

     If the respondent knows  that they  made no recommendation  during the year,  enter
     "None" on the line labeled pesticide.

     If the respondent knows  that they  made  a  pesticide recommendation, but does not
     remember the name of the pesticide,  circle  the code 98 for "Don't Know".

     If the respondent  knows  that the pesticides for  a  given year  are  the  same as  in
     Question 6, then refer to  the answer, but writing in at a specified  year.  Refer  to
     Question 6 for the list of pesticides.

     List  the  pounds per  acre  per year of the pesticide  along  with the formulation.   If
     the response is in  some other unit of measure, such as pounds of active ingredient
     per acre  record the response in the margin.

9.    This question asks for what percent  of the cropland farmed in Question 2 has been
     treated with any of the pesticides listed in Questions 6 and 8.

     The question refers to the  past 12 months.

     Zero fill the field if necessary.

10.   This question asks for what percent  of  the total volume  of  pesticide applications  is
     used by the listed methods.

     Preplan! incorporation  applies  to the  percent of  the  total  volume of  pesticide
     applications made to the land prior to planting date and incorporated into  the soil.

     Soil incorporated at planting applies  to the percent  of the total  volume of pesticide
     applications made to the land at  time  of planting below  the soil  surface.

     Pre-emergence  refers  to the percent of  the total volume of  pesticide applications
     made to the land before the  crop emerges through the soil surface.

     Post-emergence  refers to  the  percent of  the  total volume of  pesticide applications
     made to the land after the crop germinates.

     Zero fill the field if necessary.

11.   This question asks if there is a golf course in the area identified on the map.

     A golf course is defined as  an area of land laid out for the  game of golf with more
     than 9 holes each including tee, fairway, and putting  green.

12.   This question asks the relative  use of pesticides in  the  area identified on the map
     compared to  the rest of the county.

     Pesticide use in a  quadrant  is defined as "high" if  use  in that  quadrant is  greater
     relative to overall  use  in  the county. For  example,  in  a county with  20 quadrants,
     if 17  quadrants  are  non-cropped  (low-pesticide   use)  and  three   quadrants  are
     partially cropped  with moderate pesticide  use,  those  three quadrants  that  are
     cropped would be defined  as higher than the rest of the county.

13.   This question asks if any irrigation is used on the farmland.

     Irrigation refers to the application of water to the cropland by artificial means.

     If no irrigation has been used or the county  agent does  not know of any irrigation
     then skip to Question 14.

14.   This  question  asks for  the  types  of  irrigation  methods that  are  used  on  the
     cropland.

     Spray irrigation is the method of  applying water to the soil  by an overhead  spray
     system.

     Flood irrigation is the method by  which either water is  released from field ditches
     and  allowed to flood  over  the land  or whereby water  is applied to  row  crops  in
     ditches made by tillage implements.

     Drip  irrigation  is  the  method by  which water is applied  under low  pressure near
     plants by seepage through micro emitters or porous hose.

     Subsurface irrigation is the  method  by which water is added to the soil in such a
     way that it penetrates the soil from below.

     Circle either "Yes", "No", or "Don't Know" for each of the irrigation methods.

15.   This question asks for  sources of irrigation water used for  crop production.

     Ground water applies  to water that is within the earth and must be pumped to  the
     surface by constructing a well.

     Surface water applies  to a  water source from natural water  bodies including  lakes,
     rivers, and streams.

     Canal water applies to  a source of water that is used from  an artificial waterway.

     Spring water applies to a source of water issuing from the  ground.

     Sewage effluent applies to a source of  water that is the treated wastewater from a
     wastewater treatment plant.

     Circle either "Yes", "No", or "Don't Know" for each of the irrigation methods listed.

16.   This question  asks for the  average erosion potential  of  the  land identified on  the
     map.

     The land area  for  this  question pertains to both the cropland and  non-cropland.

     Sheet erosion is  defined as the removal of soil from  the land surface by rainfall and
     surface runoff.

                                         - 5 -
     Gully erosion is defined as the erosion process whereby water accumulates in narrow
     channels  and, over  short periods,  removes  the  soil  from  this  narrow  area  to
     considerable depths, ranging from 0.5 meter to as much as 25 to 30 meters.

     Wind erosion  is defined as the wearing away of the earth's surface by wind under
     natural  environmental conditions of climate, vegetation, etc., undisturbed by man.

     Local erosion  pertains to  small  land areas which  are  prone to  localized runoff
     during varying intensity precipitation events.

17.   This question asks the percent of crop management practices  performed by farmers
     located  in the cropland areas identified on  the map.

     A  no-tillage  system  is a  procedure whereby  a crop  is  planted directly into  a
     seedbed; not tilled since harvest of the previous crop; also zero tillage.

     Conventional  tillage  applies  to  the  combined  primary  and   secondary tillage
     operations  normally performed in preparing a seedbed for  a  given crop grown in a
     given geographical area.

     Intertillage  is the  practice  of  tillage   operations  performed  in  isolated  bands
     separated   by  bands  of  soil  essentially  undisturbed  by  the   particular tillage
     equipment.

     Minimum  tillage  is the minimum  soil  manipulation  necessary  for crop  production or
     meeting tillage requirements under the existing soil and climatic conditions.

     If  the respondent knows  of another crop management practice other than  the ones
     listed, write the response under "Other".

18.   This question asks for what  types  of  erosion  control  conservation measures  have
     been used  in the area  identified.

     Up-and-down  slope planting is the activity  of planting and managing  crops up and
     down the slope of the land.

     Contour planting  is the activity of planting and managing crops on the contour.

     A terrace  is an embankment with the uphill side sloping toward and into a channel
     for  conducting  water, and the   downhill side  having  a  relatively sharp decline;
     constructed  across  the  direction  of the slope  for the purpose of  conducting water
     from  the  area above  the  terrace at  a  regulated rate of  flow and to prevent the
     accumulation of range volumes of water on the downslope side of a  cultivated field.

     Circle either  "Yes", "No",  or  "Don't  Know" for each of the  conservation measures
     listed.

19.   This question asks  if there are any water drainage  systems  that are used in the
     area.

     Drainage  systems provide  channels,  such as  open ditches or  drain  tile, so that
     excess water can be removed by surface or by internal flow from a field.

     If no drainage systems are used or  the respondent  does  not know of  any drainage
     systems  then skip to  Question 19.

20.   This  question  asks   for  what  types of  drainage  systems are  used  in  the  area
     identified.

     Drainage ditches are open ditches, so that excess  water can be removed by surface
     or by internal flow.  They can be unlined or lined with sod, cement, or gravel.

     Tile drainage systems are concrete  or ceramic pipes placed at suitable  depths and
     sponges  in the soil or subsoil to provide water outlets from the soil.

     Circle either "Yes", "No", or "Don't Know" for each of the drainage systems.

21.   This questions  asks  at  what time of  year are  pesticides  applied to the major crops
     farmed in the area identified on the map.

     The questionnaire has 3 columns divided into two week time periods.   If more than
     one crop  receives pesticides at  the  same time of year  than  complete crop 2 and
     crop 3  categories.   Complete  a  continuation sheet if four or more  crops receive
     pesticide applications at the same time.

     More than one pesticide may be listed under a time period  for the same crop.

     The brand name or  trade  name  (AAtrex) of the pesticide is the  preferred response
     for each block.  Other responses include the  active  ingredient (atrazine), or type
     (herbicide) in the time period pesticide block.

I.  Introduction
      The County Agent Questionnaire (CAQ)  is a menu-driven Data Entry
System designed to facilitate entering NFS  County Agent interview
responses into the CAQ database for later analysis.
      Before you commence using the system,  please ascertain that the
Database Manager (Suha Beidas,  X-3971)  has installed all the required
software and databases on your machine.
II. Useful Tips for Using CAQ


      Before you start,  a few things to remember are:


      •   Pressing the ESC key will take you out of the CAQ data entry
         system.  You will then be taken to the Exit Screen (Figure 1).

      •   •*—I  refers to the ENTER key on your keyboard.
         14-   refers to the Up and Down arrows on your keyboard.
         -**-   refers to the Right and Left arrows on your keyboard.
         PgUp refers to the Page Up key on your keyboard.
         PgDn refers to the Page Down key on your keyboard.

      •   Pressing PgUp or PgDn will save the current screen and move you
         backward or forward one screen.

         Pressing •*—' or Ti will move you from field to field within a
         screen.  Pressing •*—' at the last field on a screen acts  like
         a PgDn.

      •   A "beep" from the terminal signals an error in the field  you
         have entered.  Refer to the screen for messages and
         resolutions.

      •   If you discover a mistake after you have completed entering
         a field (i.e. you have entered the value followed by •ซ—'), you
         must enter the next field; but rather than pressing •*—' to
         move to the next field, use T to move back to the previous
         field and make the correction needed.

A. Adding or Editing County Agent Questionnaires
      Figures 4 and 5 are sample screens for Adding a new questionnaire
or Editing an existing one.   You must specify the four key items before
any action (adding or editing) can take place.  These key items identify
each questionnaire; and thus, they are unique to each questionnaire.
These key items are:

      1. Keyer:    This is your identification number.
      2. State:    This is the State noted on the first page of the
                   questionnaire.
      3. County:   This is the County noted on the first page of the
                   questionnaire.
      4. Quadrant: This is the Quadrant Number noted on the first page
                   of the questionnaire.
      If you attempt to EDIT a questionnaire that has not been added yet
or you attempt to ADD a questionnaire that was added previously, the
terminal beeps and an error message appears.  After you read the error
message, you will be prompted to re-enter the Key Items again.  You will
continue to get this message until you supply valid Key Items for the
desired action.
      Pressing the ESC key from either screen will take you back to the
Main Menu.

      Refer to Adding and Editing Screens (page 11) for help on the data
entry screens associated with these Main Menu Selections.

B. Copying County Agent Questionnaires
      On the first page of each questionnaire, a list of quadrant
numbers is hand written at the top.  This' list consists of all the
quadrants that questionnaire applies to.  For efficiency, the CAQ Data
Entry system allows the Keyer to enter one of those quadrants in the
list; and then to Copy that quadrant to the others in the list.
Figure 6 is a sample Copying Screen.  You must specify the four key
items before you can copy the information.  Again, these four Key Items
are unique to each questionnaire and must be entered before the
specified action can take place.  These key items are:

      1. Keyer:    This is your identification number.
      2. State:    This is the State noted on the first page of the
                   questionnaire.
      3. County:   This is the County noted on the first page of the
                   questionnaire.
      4. Quadrant: This is the Quadrant Number noted on the first page
                   of the questionnaire.
      If you attempt to Copy a questionnaire that has not been entered
yet, the terminal beeps and an error message appears on the screen.
You will then be prompted to re-enter the Key Items.  The terminal will
continue to beep until you enter the Key Items of a questionnaire that
has been entered or you ESC out to the Main Menu.  Once you supply
valid Key Items, you will be prompted to enter the Quadrant Number
you wish the identified questionnaire to be copied to.  Enter the
Quadrant number in the list at the top of the page followed by •*—'.
If you enter the quadrant number of a questionnaire that has already
been entered, the terminal will beep and an error message will appear
on the screen.  You will then be prompted to re-enter the Quadrant
Number.   The system will repeat the above until you supply a new
Quadrant Number or you ESC out.
      Once you supply a new Quadrant Number, the system will copy all
necessary information; and then you will be prompted to enter the next
Quadrant Number you wish the data to be copied to.  Continue entering
Quadrant Numbers until you complete the list.  Once you've completed
copying, press ESC to get back to the Main Menu.

C. Printing County Agent  Questionnaires
      To print any questionnaire,  you must supply the Key Items of
that questionnaire.   Figure 7 is a sample Printing Screen.   Again,
the Key Items are the fields that identify each questionnaire; and
consequently are unique to each one.   If you attempt to Print a
questionnaire that has not been entered, the terminal will beep and an
error message will appear on the screen.  You will then be prompted to
reenter the Key Items.  The above will repeat itself until you either
supply valid Key Items or you ESC out to the Main Menu.
                        Printing Selection
    Enter the Keyer,  State,  County,  and Quadrant of the

I. Databases Management Additional Menu Selections
      When CAQ is invoked with Database Manager access,  a menu
(Figure 3A) similar to the previous one (Figure 3) is displayed.
However, as Database Manager,  you will perform routine database
management applications that are accessible through this menu.
There are five such applications and they will be discussed further
in part II.

II.  Database Management Routines
    A..  Packing the Databases

           This routine will  erase  any record that has been marked for
       deletion.   Once the database is packed,  the records deleted are
       lost and may not be retrieved.
    B.  Indexing the Databases

           This routine  will  index the  databases by the specified
       fields.   This will  help  organize the  database structure;  and
       allow for more efficient access  to  the respective databases.
    G.  Compare Double-Keyed  Questionnaires

           This routine  will compare  questionnaires that are entered
       at separate  times by  the  same  or  different keyer (double-entry)
       for any differences.   If  any differences  are found,  a report will
       be generated containing the State, County,  Quadrant,  Keyers,  Date
       entered by each keyer, which question,  and both responses.   This
       is then forwarded for resolution.
    D.  Print Schedule

           This  routine will  generate  the  schedule  of all questionnaires
       that need to  be double-keyed  into the  system.   This report will
       include  the following  information:   State, County, Quadrant,
       Date entered  by the  first keyer, Date  entered  by second keyer.
       This report is generated nightly for next  day  scheduling.


    E.  Print Clarification  Problems

           This  routine will  generate  a report  of all questionnaires
       that the  keyers had  problems  with.   Problems include illegible,
       writing,  missing pages in questionnaire, etc ...

           This  report will be generated nightly  for  resolution by the
       interviewer or project leader.

M.  Data Entry Screen #13
      Figure 20 is a sample of data entry screen 13.  This is the data
entry screen for questions 6, 8, and 21.  The responses to those 3
questions are provided on sheets that are attached at the back of the
questionnaire.  There are several rules that differ from the rest of
the previous data entry screens.  The following is a guide to help
you enter data into this screen.

1) At the bottom of screen 13 is a menu of actions that the user may
   select from.  Each menu selection is in the format: Key: Action.
   That is, you press the Key for the desired Action.  Only menu
   selections that are highlighted are accessible.

2) If you press F2 (QUIT), any data entered through screen 13 will be
   lost.

3) If you press F3 (Save & Exit), data entered through screen 13 is
   saved.  However, if you answer No to Save Modifications ? at the
   Exit Screen (Figure 1), this data WILL BE lost.

4) The first two questions in screen 13 (Applies to Q6 and Applies to Q8
   cannot be N.  If the response to question 5 is not recorded as 01,
   then Applies to Q6 will be set N; and the keyer will not be able to
   modify its value.   Similarly, if question 7 is not recorded as 01,
   then Applies to Q8 will be set to N; and the keyer will not be able
   to modify it's value.  If both questions 5 and 7 are recorded as 01,
   the keyer will be given the opportunity to modify both (Applies to Q6
   and Applies to Q8) when entering the data for this screen.

5) If the Pesticide Code is 9999, the Formulation Code, Application
   Rate, and Units are automatically filled out and CANNOT be changed.
   You will be required to (and you may change) the value of Crop,
   Significant Figures, Time of Application, Application Year, and the
   Specify Fields associated with Pesticide Code, Formulation Code,
   Application Rate,  and Units.   Figure 22 is a sample screen.

6) If the Application Rate is a range on the attached sheet,  you MUST
   press •*—' at the application rate first,  then you will be prompted
   to enter the range.

7) If the Application Rate is 8888.8888, the Unit is automatically
   filled out and may not be changed.   All fields on the screen with
   exception of Application Rate and Units may be modified.  Figure 23
   is a sample screen.

8) Significant figures  refers to the number of digits after the decimal
   point that were recorded for Application Rate on the original
   questionnaire.   For  example,  if 2.51 was recorded as the application
   rate,  Application Rate on the screen would say 2.5100 and Significant
   Figures will be 2.

                              4 - 13

-------
 9)  If Time of Application is  99,  the Specify field must be recorded with
    a response.   Also,  this field  scrolls horizontally,  so you may enter
    more than the 30 characters  apparent on the screen.   Figure 21 is a
    sample screen.

10)  All years of application cannot be N.  At least one  must be Y or R.
