Concurring Opinion by Jacob
D.
Dumelle
While
I voted with the 5-0 majority to defer action on the
proposed regulation
and
to conduct more research
I did so with
reluctance because there was simply nothing else
to do at this
time.
A vote for
“more research”
is often
a common way
to avoid a
decision and it must be remembered that
“not to decide is
to decide.”
To my mind,
the Board
(and
I include myself)
at an early
stage
in these hearings ought to have analyzed the record and asked that
specific witnesses be brought in to discuss the validity of the
45 mq/l NO1 standard;
the cost of nitrate removal by municipal
water planes;
and alternatives
to the proposed regulations.
iinfor—
tunatelv the hearings focused almost exclusively on fertilizer
movement in soil and were at best incidentally directed to these
other important questions.
Consequently the abilities of various
state aqencies to draw upon expert knowledge for answers was not
adeauatelv utilized early in this rule-making process.
In the
Effluent Standards proceedings
(R70—8)
the Board
in early 1971 decide~
that cost data on industrial treatment methods was badly needed and
obtained it in a short time with Institute assistance.
In the Air
Regulations
(R71—23)
the Board in recent public sessions discussed
areas where evidence was lacking and as
a result received further
information, largely from the Agency.
In my recent statement on the Proposed Phosphate Detergent Ban
CR71—b)
filed March
22, 1972
I discussed
a three question approach
to
the decision
not to act on that proposal.
Let me do the same
in
this proceeding.
The
three questions are:
1)
Is there
a problem?
2)
Is there
a solution to the problem?
3)
Can the solution be afforded?
To the first question we would all have to say
“yes.”
Both
the Illinois drinking water standards and water quality standards
are now being exceeded
as regards nitrates.
Robert Harmeson of the
Illinois
State Water Survey listed the following rivers where levels
137
equal
to or exceeding
the
45 mg/i NO3 standard have been measured:
Wabash, Embarass,
Illinois, Vermilion,
CR.
162, Nov.
3,
1971)
Mr.
Harmeson also named additional rivers where the nitrate levels
are trending upward toward the
standard.
These include the Edwards,
Kankakee,
Kaskaskia, Mackinac and Sanqamon.
Six of these nine rivers
are used
as municipal drinking water
sources.
As recently as early
March
1972
a report was released by
the Macon County
(Decatur area)
Health Department by Dr. Fred Grosz showing nitrate violations on
16 days between December
27,
1971 and February
1,
1972 of 21 days
tested in Lake Decatur which
is
fed by the Sanoamon River.
How severe is the problem?
We do not know on
the record the
extent of the “safety factor,’
if any, built
into the 45 mg/i NO3
standard
and so we do not know how urgently to view the necessity
to take action.
Are high nitrates
in drinking water as urgent
to
reduce as mercury or pesticide residues
for example?
Dr. Abraham Ceiperin,
a physician
at the University of Illinois,
indicated an abrupt threshold of
no methemogiobin in infants
at water
nitrate levels below 35 mg/i
(August
4,
1971,
p.
127-8)
.
Presumably
some methemoglobin can be tolerated by infants and the 45 mg/i
standard would seem to 1~ave some safety margin built into
it.
Of course,
this
is not conclusive, all we seem to know
is
that the prestigious
U.S. Public Health Service set the 45 mg/i NO3 standard
in i962 (per-
haps earlier)
and that the World Health Organization has followed
suit.
On the other hand,
the State of California
(alone of the
50
states)
has
doubled the standard to 90 mg/i.
Dr.
Geiperin,
in
an extended appearance before the Board
on
August
4,
l97i, discussed his preliminary findings based on crude data
of a significant increase of 56.8
in
the death rate of female babies
in high nitrate water Illinois counties compared
to low nitrate water
Illinois counties over
a ten year period.
Dr.
Gelperin promised to
refine his data prior to December
10,
1971
(the last scheduled Board
hearing in this proceeding)
and at this writing, almost four months
later,
has not done so
(p.
135).
I would urge him to complete his
study.
What could be more urgent than the prevention of infant deaths?
Another disappointment to me in this proceeding was
the lack
of data from blood testing of persons for methemoglobin levels in the
Decatur area compared to St.
Louis
(where presumably
no drinking water
nitrate problem exists).
The
study was promised to be completed by
March
31, 1972 but just got underway
in March.
Preliminary data show
Decatur methemoglobin levels twice
those of St. Louis residents but
the significance of the finding is not validated or known.
Furthermore
the postulated existence of adults with enzymatic deficiencies
such
that high nitrates cannot be tolerated
is yet to be proven.
Again,
a
public health problem may exist but we do not know its dimensions.

To the second question,
one can outline other solutions not
explored
in this record.
Since nitrates are high in Decatur for only
short periods in
a year,
the water supply authority could presumably
dilute
its purnpage by 10
or more with
a low nitrate water source,
if one
is available.
Or
the water department might remove nitrates.
But we do not know the feasibility and cost of either of
these alter-
natives.
And they do have
the disadvantage of putting the cost
burden on parties which did not cause the high nitrates.
Other al-
ternatives such
as restricting
the use of nitrate fertilizers in
selected watersheds such
as the Sangamon River should be considered.
The record suggests
that agriculture
is likely the greatest single
contributor
of. nitrates
in certain streams
such as the Sangamon.
There
is
no basis
in the record for assuming either that the present
rate of nitrate application is environmentally proper or
that it
is
even that
rate at which ontimum uptake by the crop occurs.
The
record does indicate
that because
a farmer has no adequate method
for determining the nitrogen content of his soil
(soil profile)
the
individual farmer may well be applying nitrogen beyond that level
necessary for optimum crop growth with the result that needless excess
almost certainly flows
to the streams of Illinois.
Once
a widely—
used method
for determining soil profile
is developed, rate restrictions
alonq
the
lines of
the proposed regulations may well be in order.
While
the kind of regulations needed
for
a complete answer to the pro-
blem
have
not been fully explored
a restraint on rate of application
could have
some desirable environmental effect without disrupting
food
supply.
Let us draw the parallel between watersheds
and airsheds.
The
watershed
leading to Lake Decatur
is overloaded with nitrates.
To
lessen the concentration by dilution one either adds to the water
supply by
a ground water source or by inter-basin diversion of addi-
tional water.
This
is
like pulling additional
fresh air into Chicago
and
is certainly more feasible to
do with water than with air.
But
if we
leave the water supply as being
fixed in quantity,
then we
obviously have
too many nitrate sources
for the assimilative
capacity
of the water
(legally defined as
45 mg/l NO3)
.
And the parallel is
to have
too many air pollution sources,
even well—controlled,
in a
limited airshed.
Since on
the
state of
this record we cannot adequately
answer the second question
as
to the solution of the problem we are
left adrift with the third question which
asks if the solution can
he afforded.
I
can only urge
the Institute for Environmental Quality
to bring
in what relevant testimony
it can within
a short time and
certainly no later than October
1972.
A further point in this record needs
to be addressed.
Agricul—
tural. witnesses
in this proceeding made the point repeatedly
that if
nitrates are
a problem then education and the voluntary approach
to
fertilizer reduction are the best methods to use.
I am not sure
4
-~

based upon Illinois~experience in soil conservation that the voluntary
approach will work,
In the 1967 publication, Water
for Illinois:
a
~
for action the statement appears that only
29
of Illinois
farms
containing
23
of the acreage had conservation
plans
(p.
200)
.
One
may well
ask, if in
30
plus years of voluntary soil conservation
programs only
29
of
the farms had seen
fit to comply then is volun-
tary compliance the way to reduce what may he
a severe public health
nitrate hazard?
Former Secretary of the Interior Walter J.
Hickel,
in his
new book Who Owns America?,
in discussing the generally
unsuccessful attempts of Interior’s Bureau of Mines
to get mine owners
to voluntarily comply with safety standards, capsules his analysis
and decision
as
“.
.
.after fifty years of trying
to educate it was
time to get
a good deal
firmer.”
I hope
that Illinois will shortly
find
a way to solve its high nitrate drinking water problem.
