                             INTRODUCTION

     The great strides made in  water treatment  in  past years  have
reduced the threat of the once  feared major water-borne  epidemics.
With this technological  advancement has  come a  sense  of  assurance
that our drinking water supplies  are failsafe and  free from
potential health hazards.  This false sense of  security  is  reflect-
ed not only by the average citizen, but  has spread to portions  of
the water supply industry itself.   Many  supplies have become
victims of their own success.   They have maintained a status  quo
without concern for improving the reliability of their system or
for meeting the challenge of newer and more stringent quality
standards.
     The Community Hater Supply Study (1)  indicated that compla-
cency is not restricted solely  to the citizenry and utilities,
but has spread also to the regulatory agencies.  In general,
state agencies are much less active in drinking water supply
surveillance today than in past years.  Program emphasis and
resources have been reallocated to meet the demands of new
pollution control mandates.  Although extensive water pollution
control efforts can provide improved raw water  quality,  these
programs alone do not assure safety or reliability of drinking
water.  Such assurance is attainable only through  renewed aware-
ness of  the public health significance of drinking water and  the

-------
establishment of active water supply  programs  at  the state and
local levels.
     Recognizing this, James  L.  Agee, Region  X Administrator,
Environmental Protection Agency, when requested by  the Honorable
Cecil D. Andrus, Governor of  the State of Idaho,  to assist in
supporting environmental programs in  Idaho,  recommended  as part
of a total environmental program assessment  package an evalua-
tion of the State's water supply activities.   Subsequent corre-
spondence and discussion with State water supply  program personnel
resulted in establishment of  an  agreement for the evaluation,
the purposes of which were:
     1.   To ascertain the condition  of Idaho's water  supplies
through field surveys of water supply systems, laboratory analyses
of drinking water samples for bacteriological, chemical  and  radio-
chemical  constituents, and examination of pertinent data recorded
in the  State files,
     2.   To determine the adequacy of legal  statutes, regulations
and  policies, budget  and manpower resources, surveillance activi-
ties,  laboratory support, and operator training,
     3.   To evaluate  the effectiveness of the Idaho water supply
program as  determined  by the condition of a representative
number of the State's  water supplies, and
     4.   To recommend improvements  and additions which may be
needed to assure an  adequate supply  of safe drinking water for
 residents of Idaho.

-------
     Field surveys  to determine  the  adequacy of water system
facilities, water quality,  State  laboratory facilities and opera-
tions,  and overall  public water  supply surveillance were conducted
in late 1971 and early 1972.   Additional  information concerning
subsequent legislation affecting  the water supply program, recent
organizational  changes establishing  the  Department of Environmental
and Community Services, and manpower and  funding expenditures for
public water supply surveillance  through  Fiscal Year 1973 has been
included.

                            PLAN  OF  STUDY

                       WATER SUPPLIES  SURVEYED

     Resident population  in  Idaho, according to the 1970 census,
is 713,000.   Approximately 482,000 of  these people, or 68 percent
of the State's population, are  served  by 274 public water supplies.
The health of this  segment of the State's  population is directly
affected by  the quality of their  drinking  water.   Under State law
the Department of Environmental and  Community Services is respon-
sible for establishing requirements  and providing  surveillance
of these supplies to assure  safe  drinking  water.   In addition to
the public supplies, there is an  unknown number of systems, gen-
erally designated semi-public,  which serve State residents and
the traveling public at restaurants, service stations, recreation
facilities,  trailer courts and similar establishments.  Presently
these supplies are neither listed nor  under surveillance by the
State.
     To accomplish the system evaluation  objective, the 274 public
water supplies were divided into  five  population groups as shown
in Table 1.   Twenty-eight supplies  representing  10 percent of
the State's  public water systems  were  selected  at  random to repre-
sent the respective percentage of supplies within  the  predetermined
population groupings.  The random selection was  examined and found
acceptable from  the standpoint of geographical  distribution, type

-------
of source and type of treatment.   Location  of the  supplies  is  shown
in Figure 1.
     State dental  health records  indicate  fourteen (14)  of  the 274
public water supply systems  in  Idaho adjust the  fluoride content
of their water for dental  health  protection.   A  special  fluoride
study was conducted of all  fourteen  supplies.  Figure  2  shows  the
location of the fluoridated  systems  surveyed.

                          PROGRAM EVALUATION

     The effectiveness of the Idaho  water  supply program in protect-
ing the public health was  judged  on:
     1.   Evaluation of State statues  pertaining to  protection of
the State's water resource  for drinking purposes to  determine  if
sufficient policy and regulation  setting power is  available to
conduct its activities properly,
     2.   Review of regulations and  policies  adopted by  the Depart-
ment of Environmental and Community  Services  to  determine their
adequacy with respect to current  good water supply practice,
     3.   Evaluation of the  Department's routine bacteriological,
chemical, and facility surveillance  pronram through  review  of
available records  and selected field surveys,
     4.   Review of other program activities  such  as operator
training and certification,  cross-connection  control,  fluoridation
and technical assistance to  other State and local  agencies  concerned
with water supply,

                       STUDY FINDINGS

                 WATER SUPPLY SYSTEM STATUS
     The 28 water supplies  surveyed provide  drinking water to
approximately 1/5 of Idaho's population  served  by  the public
water supplies and are judged to be representative of public
supplies throughout the State.   The findings  of the survey are
presented below by major categories examined.

Hater Quality - Bacteriological
     Bacteriological testing is  essential  to  determine if
drinking water is safe.  The Drinking  Hater  Standards recognize
the coliform organism group as  a reliable  indicator of the
bacteriological quality of  drinking water.   The presence of
coliform organisms in the distribution system suggests either
inadequate treatment or access  of contaminants  to  the water
after treatment.  Failure to meet the  bacteriological quality
standards indicates that the water is  a  potential  carrier of
infectious disease.  Such a situation  is  a serious potential
health hazard and calls for immediate  corrective action.

          Of the Idaho systems  examined, 21  (75 percent) either
          did not meet the  bacteriological quality standards
          two or more months during the  twelve-month period prior
          to the survey, or failed to  collect sufficient samples

-------
          during this  same  period  to  assess  the bacteriological
          quality.   These systems  serve  a  combined peculation
          of 13,750.  Considering  only  those water samples
          collected during  the  survey,  five  systems  (18 per-
          cent) failed to meet  the bacteriological quality
          criteria  of  the Drinking Water Standards.  Comparison
          of bacteriological  sampling results to system size
          indicates that smaller water  systems in Idaho gen-
          erally distribute water  of  poorer  bacteriological
          quality.

Water Quality - Chemical
     Drinking water should  not  contain  substances which arc toxic
or may cause adverse health effects.  The  Drinking Mater Standards
establish mandatory chemical  limits for  these substances.  Sup-
plies or individual sources from which samples have been confirmed
as failing to meet  these standards  should  be rejected.

          One of the public water  supply systems (4 percent)
          examined  in  Idaho did not meet mandatory chemical
          drinking  water standards.   The system failing to
          meet the  mandatory  chemical standard serves a pop-
          ulation of approximately  400.
     Good quality drinking  water should  not  contain substances
                             12

-------
which adversely affect its appearance, odor and taste, or which
cause discomfort to man.  The Drinking Water Standards set recom-
mended chemical limits to assure that drinking water contains  no
substance in concentrations which would render it undesirable  or
aesthetically inferior.  A supply or source of water failing to
meet these standards should be considered for treatment or used
as standby for alternate higher quality sources.

          Seven Idaho water systems (25 percent)  failed to meet
          one or more of the recommended chemical  limits.   These
          systems serve a combined population of over 80,000.

Facilities and Operation
     Water supply facilities include all structures  and equipment
utilized for collection, treatment, storage and distribution of
drinking water from the source to the customer's  tap.   These
facilities and their operation must be capable of consistently
producing adequate quantities of safe drinking water and pre-
venting contamination from entering the system.   Any condition,
device or operational practice which allows water of questionable
quality to be provided to the consumer constitutes  a potential
health hazard.

          Fourteen Idaho systems (50 percent) had inadequate
          protection of the sources against contamination.
                             13

-------
Nine of these fourteen  supplies  also were  found  to
have either inadequate  treatment or none at  all.
Ten Idaho systems  (36 percent) need either additional
treatment facilities  or improved protection  of the
source of supply.

Eleven Idaho systems  (39 percent)  had  inadequate
distribution system facilities or need improved  oper-
ation of existing facilities.

Twenty-seven Idaho systems (96 percent) were providing
inadequate quality control to  assure protection  of  the
water supplied.  A number of the larger supplies were
providing appropriate bacteriological  and  chemical
testing and were maintaining operating records.   Only
one supply was judged to be carrying out  an  adequate
cross-connection control program.   Most of the smaller
supplies were deficient in two or more of  these  areas.

Twenty Idaho systems (71 percent) employed operators
who had never participated in  any water supply  opera-
tors short  course training.  Many operators, although
aware of their lack of knowledge on critical public
health aspects of water supply operations, felt  they
could not be away from the job for even short course
trainina.
                    14

-------
          Only two (25 percent)  of the eight Idaho fluoridation
          installations in operation at the time of the  survey
          were providing a fluoride content in  the range recom-
          mended by the State for maximum dental  health  benefits.

          Four (50 percent) of the eight operating Idaho fluori-
          dation installations had unsatisfactory storage  of
          chemical compounds and inadequate fluoride  feed  equip-
          ment.

          None of the eight operating Idaho fluoridation installa-
          tions  was providing complete analytical  control  of  the
          fluoride feed level.

Surveillance
     Surveillance of water supply systems  is  one of the  essential
responsibilities of a state health agency.   It  requires  routine
monitoring of bacteriological  and chemical  water quality to detect
possible contamination, and regular review  of system  facilities
and operational  procedure to prevent serious  health hazards from
developing.

          There  is no complete,  updated inventory of  all  the  Idaho
          public water supplies  for which  the Department of Envi-
          ronmental and Community Services  is responsible.

          Twenty-two (78 percent) of the Idaho  systems evaluated
          had not been subject to a sanitary survey within the
                             15

-------
previous 12 months.   The  average  period  since  the  last
sanitary servey was  over  seven  years.

Nineteen Idaho systems  (68 percent)  failed  to  collect
the required number of  bacteriological samples  two or
more months of the previous 12-month reporting period.
Little resampling or investigation was done as  a
follow-up to samples showing contamination.

Twenty Idaho systems (71  percent) had not  received a
chemical analysis within  the previous three years.
The average period since  the last chemical  analysis
was nine years.  Those  analyses which were  completed
did not include important health parameters such  as
arsenic, cadmium, chromium, cyanide, lead,  selenium
and silver.
'Jo routine surveillance has been provided  for Idaho
communities which adjust the fluoride level in their
water supply.  Little surveillance of bottled water
or bottling operations  in Idaho has  been provided.

                    WATER SUPPLY PROGRAM





     The conditions of water supply facilities  and  drinking water



quality are directly related to the implementation  of  adequate



regulatory powers and the provisions of training and technical



assistance programs for water supply operators.   The generally



poor public health conditions and practices  found in the  field



survey are largely attributable to the lack  of  an aggressive



water supply program at the State and local  levels.  Signifi-



cant features of the State program are described below.





Authority, Regulations and Standards



     The Idaho statues give broad authority  to  the  Board  of



Environmental and Community Services for regulation  of public



water supplies.  Administrative responsibility  for  implementing



these acts is vested in the Administrator of the Department of



Environmental and Community Services.
                                              *


     Regulations governing protection of public  water  supply



were issued in 1964.  These regulations, Idaho  Drinking Water



Standards (5), adopt the U.S. Public Health  Service  Drinking Hater



Standards, 1962 Edition, and orovide standards  for  design and



construction of drinking water system facilities.  In  addition,



minimum well construction standards were adopted by  the Depart-



ment of Water Administration in 1968 and all  water  well contrac-



tors are required to be licensed.  These two sets of regulations

-------
are generally adequate to permit operation  of an  acceptable  public
water supply program.

Organization, Manpower and Budget
     Considerable reorganization of health  and social  service
agencies has occurred recently in Idaho.  At the  time  of the
field surveys in 1971-1972 the water supply program was  organi-
zationally located in the Department of Health.   At that time
the water supply activity was not an identifiable unit within
the parent organization.   General program direction was  pro-
vided by the Chief of the Engineering Division and field work
was accomplished by individuals in the three Health Department
Regional Offices.  The total  manpower allocations for  water  supply
surveillance and technical assistance in  fiscal years  1971 and
1972 were 1.0 man-year.  Estimated expenditures  for field acti-
vities were $22,000.  Laboratory support increased total water
supply program expenditures to $91,000 per  year.
     Action by the 1972 and 1973 Idaho legislatures resulted in
reorganization of the State health programs and establishment of
the Department of Environmental and Community Services.   General
water supply program direction is now provided by the  Director
of Categorical Programs with field work being carried  out by the
regional offices staff under direction of the Director of
Regional Operations.  Manpower allocations  for water supply
                             18

-------
activities increased to 2.7 man-years in fiscal  year 1973.   Total



expenditures, including laboratory support,  increased to  $124,000.



Although these increases have improved the State's  water  supply



surveillance activities over that at the time  of the field  survey,



the overall effort remains inadequate and the  water supply  program



is not yet considered to be fulfilling its responsibilities.



     The State has not delegated to the local  Health Districts



any portion of the responsibility for enforcement of the  State



public water supply regulations.  Informal working  agreements



have evolved between certain Health Districts  and the State



regional engineers.  However, the ultimate potential  for  fully



utilizing the Health Districts in selected areas  of surveillance



and enforcement of water supply regulations  has  yet to be



developed.





Engineering Activities



     Few formal  inspections and follow-up surveys of water system



facilities  along with limited review of water  quality and opera-



ting records have resulted in little enforcement  of established



standards.   Enforcement is hampered, not only  by  lack of manpower



to carry out field surveys and laboratory analyses, but also by



the continued use of a time consuming,  manually  operated  data



recording and retrieval system.



     Review of plans and specifications  for  new  construction and



modifications to existing water system facilities has  been carried





                            19

-------
out with some degree of regularity.   This  effor,  along with
providing technical assistance on  special  problems  and emergencies,
has accounted for the majority of  the professional  manpower
resource allocation to water supply  activities.
     The Department conducts an annual  three-day  water supply  and
wastewater operators short school.   Many of the smaller water
system operators, who most need the  training,  are not being
reached by this program.  The State  maintains  voluntary operator
certification programs for both water supply and  wastewater
operators.  As of July 1973, 178 water supply  operators repre-
senting 38 communities (14 percent)  have been  certified under
this program.

Laboratory Support
     Bacteriological and chemical  laboratory support for  the
water supply program is provided by the Department's Laboratory
Section.  Facilities and analytical  procedures were evaluated
at the chemical laboratory and three of the six  bacteriological
laboratories.  Procedures and operations were found in  general
compliance with recognized analytical methods.  Additional
emphasis will be  required to provide laboratory  capability to
routinely analyze  for toxic chemicals in drinking water.
                              20

-------
     In summary, the Idaho Department of Environmental  and
Community Services is not providing the  surveillance  and  con-
sultative services necessary to fulfill  its  responsibilities
to protect the health of those who drink water from public  sys-
tems in Idaho.  It is evident that Idaho must  implement an
expanded water supply program with increased commitment in  the
overall spectrum of activities that will  assure the State's
residents and visitors an adequate and safe  supply  of drinking
water.
                             21

                       RECOMMENDATIONS


     A primary purpose of this evaluation was to propose recom-

mendations needed to provide an effective water supply program

for Idaho.  To properly provide the health evaluations, engin-

eering services, and technical assistance necessary,  it is

recommended that:

     1.   The water supply program be upgraded to a stature

commensurate with its importance to the health of Idaho resi-

dents and visitors with a minimum annual  budget of $239,000

allocated as follows :

          a.   Engineering surveillance and       $128,000
                 activities

          b.   Laboratory services                  71,000

          c.   Management and overhead             40.000

                                                  $239,000

     2.   The water supply program  manpower resources  be  increased

to a minimum of 6 man-years  of professional  staff and  2  man-years

of secretarial  support, to provide  essential  surveillance, train-

ing and program direction activities.

     3.   The bacteriological  surveillance  program be  redirected

to:

          a.   Encourage  water supply  purveyors  to develop their
own bacteriological  monitoring program,

          b.   Charge  a reasonable  fee to  cover the cost  of
routine bacteriological  analyses, and

-------
          c.    Conduct  a check  sampling  program,  at State expense,
to assure validity of routine sampling by  purveyors.

     4.    The chemical  surveillance  program be expanded  and

modified to:

          a.    Conduct  at least one  complete  chemical  analysis on
each surface  water supply annually  and on  each ground  water
supply triennally, and

          b.    Discontinue the  practice  of performing  chemical
analyses for operational control  which are considered  the respon-
sibility of the water supply purveyor.

     5.    Enabling legislation  be adopted  requiring:

          a.    Mandatory certification of  all public water supply
facility operators,

          b.    Coordinated planning and  development of new public
water supply systems and the consolidation of the large  number of
small suppliers in urbanized regions of  the State, and

          c.    Fluoridation of  community water supplies  not
containing dentally significant concentrations of natural fluo-
rides.  Enactment of this requirement should  be  delayed  until
qualified operators are available and the  Department's surveil-
lance and monitoring program improves.

     6.    The 1964 Idaho Drinking Water  Standards be  revised  to:

          a.    Recognize recent organization  changes,

          b.    Update water quality and  monitoring criteria,

          c.    Incorporate special  design, operation  and moni-
toring requirements for small  public water supplies and  bottled
water facilities,

          d.    Establish chlorination as the  minimum  treatment
for all  public water supplies  and filtration  for all  surface
water sources with individual  cases being exempted at  the dis-
cretion of the Administrator if the purveyor  can demonstrate
adherence to standards with disinfection alone,  and

          e.   Reflect improved water treatment  and  distribu-
tion practices.
                             24

-------
     7.   A program be established to document present  and future

policy decisions for distribution in a water supply program

policy manual.

     8.   Surveillance of all  public water supplies be  increased

to provide at least the minimum levels set forth  in the Drinking

Hater Standards and the Manual  for Evaluation of  Public Water

Supplies, including but not necessarily limited to:

          a.    Development and continued updating of a  compre-
hensive inventory of public water supplies,

          b.    Thorough annual  sanitary surveys of each system
with follow-up  as required,

          c.    Increased effort to assure minimum bacteriological
sampling along  with the required check samples  from all  supplies,

          d.    Establishment of a routine complete chemical
sampling program for each supply,

          e.    Establishment of a program to encourage  adoption
of local cross-connection control  ordinances and  institution of
viable surveillance programs for elimination of backflow condi-
tions,

          f.    Increased emphasis  on surveillance  of fluoridated
supplies to assure  adequacy of these operations,  and

          g.    Initiation of a surveillance program to  assure that
bottled water quality and bottling practices comply with estab-
lished standards for food packaging and water quality.

     9.   Operator  training be  improved by:

          a.    The  Department  working more closely with  the State
universities  and community colleges on operator entry level and
upgrade training programs, and,

          b.    Increased program flexibility to meet the needs
and schedules of both full and part-time operators.
                             25

-------
    10.    Computer services  be  utilized  for storage and retrieval
of water quality data,  engineering  report information, monthly
operating report records  and inventory data.
    11.    A memorandum  of agreement be developed with each Health
District for surveillance of and  technical assistance to the
State's  small  public and  recreational water supply systems.
