ENVIRONMENTAL PROTECTION AGENCY,
Respondent.
SUPPLEMENTARY OPINION AND ORDER OF THE BOARD (by Mr. Dumelle):
On February 16, 1978 the Board denied Petitioner a variance
from the standard for barium in Rule 304 B 4 of Chapter 6:
Public Water Supplies. On April 13, 1978 the Board reopened
the record in this matter. On February 1, 1979 the Board
granted Petitioner’s motion to reconsider the prior denial of a
variance and agreed to reevaluate the prior decision. The
Agency has recommended that a variance be granted subject to
conditions.
Petitioner has submitted sections of a draft USEPA document
on guidance for the issuance of variances and exemptions from
the maximum contaminant levels in the National Interim Primary
Drinking Water Regulations. Since Illinois has not received
primary enforcement responsibility under the Safe Drinking
Water Act, the Board lacks authority to grant variances from
the Federal standards. Consequently, the Federal guidance can
only be viewed as the latest views of USEPA although it is
valuable in that respect.
The guidance document states that a level of 2 mg/i barium
in drinking water should be safe for adults and that a level of
1.0 mg/i (which is also the Illinois standard) should provide
an adequate margin of safety. The U.S.S.R. has established a
standard of 4 mg/i.
The guidance document discusses the preliminary results of
an epidemioiogical study which has since been published and
received by the Board. The study is entitled Health
Effects of Human Exposure To Barium in Drinking Water
(EPA-600/1-79—003). The study presents the results of
comparisons of human mortality and morbidity rates in Illinois
communities whose drinking water exceeded or met the barium
standard. The study found significantly higher death rates
from “all cardiovascular diseases” and “heart disease” when
barium exceeded 2.0 mg/i in finished water. The study advises
caution in making any inferences from this conclusion. The
study also found some significant differences in systolic blood
pressure levels but these results were deemed inconclusive because
of inconsistencies in the data. The study found no significant
differences in the prevalence of hypertension, heart disease,
33—185
—2—
stroke, or kidney disease. In addition no significant
differences in these conditions could be attributed to relative
levels of sodium concentrations. Consequently, home water
softeners (which raise sodium levels) were found to have no
association with cardiovascular disease. This conclusion is
important because water softeners remove barium from drinking
water. Since the use of home water softeners cannot be
controlled, any conclusions on relative incidences of
hypertension, heart disease, stroke, or kidney disease must be
viewed with caution.
The guidance document recommends exemptions (similar to
Illinois variances) for communities
“. . .
whose drinking water
has barium concentrations up to 4 mg/i providing no adverse
health effects attributaLle to the drinking water are
discernible.” The guidance document goes on to state: “The level
of 4 mg/i in drinking water was calculated from the data
suggesting that adsorption of barium from the gastrointestinal
tract in children is approximately 25 of ingested amounts.
Therefore a 10 kg child drinking 1 liter of water containing 4
mg/l barium would adsorb only 1 rng of barium.”
The finished water from three of Petitioner’s wells (Nos. 6,
7 & 8) contains barium in excess of 1.0 mg/l and two of these
exceed 4.0
mg/i
although
none
exceeds 5.0 mg/i. Petitioner has
agreed to operate and maintain its system so that no finished
water would exceed 4.0 mg/i.
Petitioner claims that denial of a variance would cause
hardship for two reasons. First, Petitioner has no excess
capacity or alternative water source to replace these wells.
Second, Petitioner has no excess funds to install additional
barium removal equipment. Petitioner is asking for relief until
January, 1981 so that it can re—evaluate costs, methods, and
treatment to meet the standard.
Petitioner has attached an affidavit executed by Dr. Frank
Fiorese, a toxicologist. Dr. Fiorese has concluded that the
barium found in wells 6, 7 & 8 occurs in the form of barium
sulfate. As such, he concludes, it will not diffuse through the
gastrointestinal wall, will not reach the blood stream, and is
not toxic.
The Agency supports a variance in this instance because
Petitioner’s existing zeolite softening equipment can reduce
barium down to the 4 mg/i limit. Although USEPA may consider
changing the Federal barium standard or the date for compliance,
the Agency does not believe that Petitioner should rely on this
contingency. Consequently, the Agency recommends that Petitioner
devise a compliance plan within 6 months to meet the present
standard.
Denial of a variance would constitute arbitrary or
unreasonable hardship on Petitioner. Petitioner has the ability
33—186
—3—
to treat its water to a level which has been recommended as safe
on an interim basis. The Board will not require Petitioner to
conduct a survey of blood pressure levels among its high risk
residents as recommended in the guidance document. A survey of
this nature would involve considerable expense and would he of
dubious value in light of the inconsistent results obtained in
the USEPA health effects study.
This Opinion constitutes the Board’s finding of fact and
conclusions of law in this matter.
ORDER
It is the Order of the Pollution Control Board that
Petitioner be granted a variance from the maximum concentration
limit for barium in Rule 304 B 4 of Chapter 6: Public Water
Supplies until January 1, 1981 subject to the following
conditions:
1) Petitioner shall maintain a level of 4.0 mg/i barium
in its finished water.
2) Within six months of the date of this Order, Petitioner
shall develop a program which will result in compliance
with the present barium standard (1.0 mg/l) and shall
submit the program to the Agency for approval. If the
program, as approved, provides for the installation of
new equipment or the development of additional raw
water sources, Petitioner shall obtain the necessary
Agency permits and submit quarterly progress reports to
the Agency.
3) Within 45 days of the date of this Order, Petitioner
shall execute a Certification of Acceptance and
Agreement to be bound to the terms and conditions of
this variance. This 45 day period shall be held in
abeyance if this matter is appealed. The Certification
shall be forwarded to the Illinois Environmental
Protection Agency, Division of Public Water Supplies,
2200 Churchill Road, Springfield, Illinois 62706 and
shall read as follows:
