Introduction

1.1

Purpose of this Report

The purpose ofthis report is-to identify, discuss, and analyze the circumstances

and effects of a site specific water quality standard for the City of Galva, Illinois,

to discharge boron concentrations in their wastewater treatment plant effluent in

excess ofthe illinois Environmental Protection Agency's (IEPA) currentlimits.

The City of Galva has been working with the IEPA and intends on filing a

petition

to the lllinois Pollution Control Board (IPCB) requesting a site specific

water quality standard for the discharge from both the Northeast Sewage

Treatment Plant and the Southwest

Sewage Treatment Plant.

Scope of this Report

The scope ofthis report includes pertinent background information on the City of

Galva's existing sewage treatment and water treatment facilities. This report also

includes information on the affected natural resources, an analysis ofthe limits.of

the adjusted standard, and a discussion ofthe environmental effects of a site

specific water quality standard. Alternative solutions to

an adjusted standard are

also discussed

in

this report.

Background Information

The City ofGalva is a community of2,758 people located in the south central

portion

ofHenry County, lllinois. Galva occupies portions ofSections 21, 26, 27,

28,33,34 and 35 in Township 14 North, Range 4 East ofthe Fourth Principal

Meridian,

Henry County, Illinois. Refer to Figure 1 for a location map,and to

Figure 2 for a city map.

The City'ssewage treatment process consists oftwo (2) plants. The Northeast

Sewage Treatment Plant (Northeast STP) is an activated sludge plant that

discharges into an unnamed tributary ofthe South Branch ofthe Edwards River.

The Southwest Sewage Treatment Plant (Southwest STP) is an aerated lagoon

system that discharges into Mud Creek, a tributary of Walnut Creek, a tributary of

Spoon River. Refer to Figure 3 for a map depicting the affected streams.

The Southwest STP accepts numerous domestic wastes as well as pretreated

industrial waste from the Dixline Corporation, ametal finishing plant. While

sampling

for a site specific metal translator (copper and nickel) as part ofthe

City'sNPDES discharge permit, it was discovered that the boron levels in the

discharge was above the set limit of 1.0 mglL.

The levels ofboron from the discharge at the Southwest Plant have'beentraced by

City personnel back to the Galva Municipal Water Supply. Recent samples taken

from the Galva Municipal Wells show boron levels of 1.0 mg/L and 1.1 mgiL,

respectively, for Well #4 and Well #5. A copy ofthese test results is available in

the appendix ofthis report.

Existing Facilities Information

2.1

Northeast Sewage Treatment

Plant

The Northeast STP, as stated above, utilizes an activated sludge process to treat a

design average flow of 0.385 MGD and a design maximum flow of 0.867 MGD.

Refer to Figure 4 for a schematic ofthe Northeast STP.

The Northeast STP discharges into an unnamed tributary ofthe South Branch of

the Edwards River located in the Mississippi Central River Watershed. The

effluent travels approximately 1.1miles downstream to the South Branch ofthe

Edwards River. The South Branch ofthe Edwards River travels approximately

15.0 miles downstream andjoins the Edwards River.

Discharge from the Northeast STP is permitted under NPDES Permit

No.IL0026344, which is included in the appendix ofthis report. Sampling and

reporting ofeffluent boron levels are not required by this permit. A chart of

discharge flows from both ofthe sewage treatment plants may be found in Figure

Considering that the boron levels being experienced at the Southwest STP have

been traced

back to the Galva Municip.al Water Supply; it.canbe

assum~d

that-the

boron

levels in the effluent from the Northeast STP are somewhat similar.

Testing conducted

in

July of2005 shows the correlation ofthe two STP

discharges.

These testTes.ults are available in the appendix

ofthis.

report..

2.2

Southwest Sewage Treatment Plant

The Southwest STP, as previously stated, utilizes an aerated lagoon process to

treat a

design average flow of 0.3 MGD and a design maximum flow of 1.0

MGD. Refer to Figure 6 for a.schematic ofthe Southwest SIP.

The Southwest STP discharges into Mud Run Creeklocated

in

the Spoon River

Watershed.

The effluent travels approximately 7.0 miles downstream to Walnut

Creek.

Walnut Creek then discharges into the Spoon River 31.7 miles

downstream.

J

Discharge from the Southwest STP is permitted under NPDES Permit

.

No.IL0023647, which-is included in the appendix ofthis report. The permit was

issued June 4,2004, and effective July 1,2004, and included effluent sampling

and reporting requirements for boron with a

limit of 1.0 mg/I. However, this

permit

was subsequently revised and reissued August 4,2004, and effective

September 1, 2004. The revised permit has a condition with a compliance

schedule to achieve the permitted levels

of boron in the effluent.

A chart

ofthe boron levels measured at the Southwest STP from September of

2004 through May 30, 2008 compiled by Mr. Larry Lawson, Plant Operator, may

be seen

in Figure 7 ofthis report. The maximum concentration was 3.0 mg/L in

September of2006.

It should be noted thatthe results show the effect of the increase in flow to the

facility due to rainfall infiltration into the sewage collection system. Also

the

effects ofthe 2006 drought conditions experienced in illinois decreased the flows

into the STPs and along

with evaporation, resulted in higher boron concentrations

in the water discharged.

Galva Municipal Water Supply

The City of Galva currently owns, operates and maintains a potable water supply,

storage and distribution system within the City'scorporate limits. The origins

of

this system date back to 1894, when Well No.1 was drilled at the water works

immediately east

ofthe public square. Since that time, the City of Galva has

made several major improvements and modifications to its public water supply.

At the present time, the City

of Galva is producing potable water from both Well

No.4 and Well No.5. Refer to Figure 2 for.the location of the wells within the

City

of Galva and in relation to the location of the sewage treatment plants. The

City

of Galva currently uses an average of approximately 400,000 gallons of

water per day. A further description of how water is produced at each well site is

as follows below.

Well

No.4, located near the southwest corner ofNE 2

nd

Street and Center

Avenue, was drilled

in 1933 to a depth of 1,686 feet, stopping in the Shakopee

Dolomite Formation. The well pump installed in this well is a

turbine pump set at

a depth

of450 feetbelow ground level. The pump is driven by a 100 horsepower

motor and has a nominal pumping capacity

of 550 gallons per minute (gpm).

During the early 2000's,'excessiveradium concentrations were discovered in the

water from Well

No.4. To exclude the radium bearing waters from this Well, the

Well was successfully lined, leaving the effective depth of the Well at 834 feet.

This procedure reduced the capacity

ofthe Well to approximately 420 gpm.

Water from the pump in Well

No.4 is discharged into a 600 gpm capacity forced

draft aerator. This unit sits approximately 20 feet above ground level, being

mounted on top

of a 43,000 gallon steel ground storage tank.

Well

No.5, located on the south side of U.S. Route 34 on the eastern edge of

Galva, near the City'sMaintenance Building, was drilled

in

1988 to a depth of

1,770 feet, stopping in the Shalcopee Dolomite Formation. The well pump

installed in this well is a submersible pump set at a

depth of 540 feet below

ground level. The pump is driven by a 125 horsepower motor

and has a rated

pumping capacity

of 600 gpm.

During the early

2000's, excessive radium concentrations were discovered in the

water from Well

No.5. To exclude the radium bearing waters from this Well, the.

Well was successfully lined" leaving the effective depth ofthe Well at 794 feet.

This procedure reduced the capacity

ofthe Well to approximately 420 gpm.

3.1

The water works system at the site ofWell No.5 works in a manner similar to

that ofthe system at the site of Well No.4. Water from the submersible pump in

Well No.5 is discharged into a force draft aerator, which is mounted on top ora

20,000 gallon ground storage tank.

Galva'stwo water works/well sites are located approximatelyo/.t of a mile from

each other, but work in tandem to supply water to the citizens of Galva through a

series ofinterconnecting 6" and 8" water mains that form the heart ofthe City's

potable water distribution system.

The excess boron levels found by Mr. Lawson at the STPs can be directly traced

back

to the municipal water supply, as boron is a naturally occurring element in

the

City of Galva's Municipal Water Supply. Refer to the appendix ofthis report

for testing results. While the levels ofboron experienced at the STPs have been

traced

back to the drinking water, the potable water supply for the City of Galva

remains in compliance with Federal and State Water Quality Standards.

Evaluation of Potential Solutions

Wastewater Treatment Options

Prior to considering a site specific water quality standard, the City of Galva

considered several options for solving the boron concentration problem in their

wastewater effluent.

I

I

!

I

,.1

3.1.1 Ion Exchange

Ion exchange has been used successfully for boron removal. Ion exchange is a

process

which selectively removes ions from water. This is accomplished by

exchanging them with other ions which are attached to an exchange media or

resin.

With aproperly selected resin, the :undesirable ions are replaced by the

resin

as the water passes through the exchange media. When the supply of resin.

becomes saturated, the media is backwashed, regenerated with a solution of acid,

and rinsed.

A properly operated ion exchange plant will reduce the boron levels in the feed

water by approximately 90%.

Usually the wastewater from backwashing, regenerating and rinsing is discharged

to drain after the Ph is adjusted. However, in tIns instance that is obviously not an

option.

I !

The wastewater concentrations of boron from the regeneration cycle would be

approximately 3100 mg/I. Even with dilution

of the regeneration wastewater

from the backwash and rinse cycles the concentration

of boron would be about

375 mg/I.'

Assuming

an ion exchange unit at each ofthe STps'an.dtreating 50% ofthe

effluent, approximately 5000 gallons ofwastewater would be produced at each

STP every

8-9 days, This means that ever 4

th

or 5

th

day 5000 gallons of water,

highly concentrated with boron, would have to be disposed

of.

The most reasonable method of disposal would be to pump or truck the water to a

large sewage treatment plant that discharges to a major river.

Tbis

would be one

ofthe plants in the Quad Cities or Peoria, both approximately 50 miles away.

Typically, evaporation ponds have not been effective

in the central Illinois

climate; however, with the relatively small amount

of wastewater being generated

evaporation

as a disposal'methodmight be possible. Numerous project specifics

would need

to be known and analyzed to mal<:e that determination.

Although an ion exchange system would need to

be installed at both STPs,

operation would only

be necessary when infiltration levels do not provide

adequate dilution to reduceboron levels below the permit limits,

UnfortUnately,

the number of days that operation would be required cannot be predicted because

it would be entirely weather dependant.

The estimated cost to construct an

ion exchange system at each

STP may be seen

in

Figure 8. This estimate does notinclude operation and

maintenance costs which would add considerably to

the long term costs.

Potable Water Treatment Options

The City of Galva also considered treating their potable water supply to reduce

the amount ofboron in the wastewater effluents.

3.2.1 Potable Water Ion Exchange Process

The ion exchange process, as discussed above,could be utilized to treat the

potable water supply to reduce the levels of boron prior to the water being sent to

the distribution system and ultimately to the STPs.

:1

Unlike treating at the STPs, the treatment would have to operate every day. Even

if only about 50% ofthe water is treated, reducing boron levels to approximately

55% - 60% of current, the same 5000 gallons ofwaste from the regeneration

cycle, and the associated disposal problems would be generated every 7-8 days.

For the purposes ofthis report,

it

has been assumed that treatment facilities would

be constructed on City property near Well #5. Well #4 would pump to the facility

Potable Water

Reverse Osmosis

Process

Reverse osmosis (RO) has been successfullypilot tested and ilsed in full scale

operation

for boron removal, although, somewhat just recently and not as

commonly as the ion exchange process.

----------R8-is-a-membrane-separation-technique in which a semi-permeable membrane

allows water permeation while acting as a highly selective barrier. This barrier

allows separation ofinoiganic and microbial species.

In

RO, an external pressure

difference

is applied to the solution, causing water to flow against the natural

direction through the membrane producing

water purer than the original solution.

RO presents a much larger problem with the waste disposal issue than the ion

exchange option. A typical RO unit would have a 75% recovery rate. In other

words, 100 gallons offeed water would result in 75 gallons ofpermeate, or good

water, and 25 gallons of concentrate to be sent to waste. However, considering

pre

and post cycle flushes, to rinse the membranes, about 1/3 of the feed water is

actually sent

to waste. Similarto the ion exchange option, if only 50% ofthe

water

is treated to reduce the levels of boron this would generate approximately

100,000 gallons of waste each day.

Obviously, this is too large of quantity to be trucked to another facility or to

consider evaporation ponds, which are not effective in the centrallllinois climate,

leaving

deep well injection as a method of disposal.

Deep well injection has been used for disposal ofRO concentrate, primarily for

seawater treatment

plants, in some locations in the United States. The use of deep

wells

has been limited to seawater plants because the concentrate from treating

seawater is

so highly mineralized that there is practically no other option for

disposal.

On the other hand, the concentrate from treating thebrackish well feed

water

can be satisfactorily diluted by merely discharging to a municipal sewer

system. Usually when the decision is made

to treat seawater the available options

to provide a potable water supply are so limited that the huge cost for a deep well

disposal system can be justified.

For the purposes ofthis report, it has been assumed that treatment facilities would

be constructed on City property near Well #5. Well #4 would pump to the facility

to be treated, or blended, and pumped back to the Well #4 site to utilize the

, ' existing storage reservoir

and the high service pumps to the distribution system.

An estimated cost to construct a RO system at the property near Well'#5 is

,included in Figure

10. This estimate does not include operation and maintenance

costs, which would be significant.

3.3

Alternative Water Sources

The City researched several alternative water sources to solve its boron discharge

problems. For map depicting each of the options discussed below refer to Figure

11.

3.3.1 Drill a New Well

Locating and utilizing an alternative source ofboron-free water to blend with, or

replace, the City's current water supply would provide a solution to the problem.

Most ofthe public water supplies owned by surrounding communities are served

by deep wells drilled into the same or similar geologic formations as the wells in

the City of Galva.

Shallow wells in sand and gravel deposits would be the most likely source of

boron free water. Consulting the "Groundwater Geology in Western Illinois,

North Part" published as Circular 222 in 1956 by the Illinois State Geological

Survey, indicated that the nearest location with the potential for this type ofwell

is

in

the far northeastern po:rtion of Hemy County near the Green River. This is a

straight line distance of20 to 25 miles.

A

search ofthe Illinois State Water Survey'sPrivate Well Database revealed that

there are very few private shallow wells anywhere near the City of Galva. A well

for a private residence would not need to produce a large quantity ofwater, and

the fact that there are very few would seem to confirm that the Green River

Valley is in fact the nearest location available.

This option would require a test-drilling program to determine whether suitable

deposits are present and,. ifpresent, whether or not an adequate supply can be

obtained. Other factors to be considered would be the availability ofland, the

type of well, or. wells, that would necessary, pumping facilities and a transmission

main to Galva.

An up-front cost estimate for this option can not be presented at this time because

so many factors would depend upon the results ofthe test drilling program.

Discussions with a well driller, familiar with the area, resulted in a recommended

budget figure of $1 00,000 for a preliminary test drilling program.

3.3.2 City of Kewanee

Another potential source of boron free water is the City ofKewanee, which is .

approximately 12 miles northeast from Galva;

The City of Kewanee has recently installed two new reverse osmosis water

treatment plants to treat potable water from its mUIiicipal wells. An initial inquiry

to the City ofKewanee regarding a pipeline and subsequent purchase oftreated

water

by the City

of

Galva was determined 'tonot be feasible by the City of

Kewanee, due to amount ofwater that maypotentially.be needed by Galva in the

future.

3.3.3 City of Galesburg

Another source of boron-free water exists in the City ofGalesburg, located

approximately 22 miles southwest ofGalva.

The idea of a Galesburg to Galva

pipeline has been around for quite a number ofyears. Initial discussions have

taken

place between the City of Galva and the City of Galesburg regarding such a

project and they have been positive. A report discussing the technical issues and

estimated

costs that would be faced by such a project has just recently been

completed and presented to the City of Galva for consideration.

The

estimated cost of such a pipeline project is a very complex issue, with several

municipalities along the route andquestions

ofhow the proportionate share ofthe

costs are to be detennined.Fiom the report, the City of Galva's share would be.

approximately $13.6 million of the total estimated project cost of $16.1 million.

This

estimate does not factor in operation and maintenance costs which are

expected to be very significant.

It should benoted that the contact with the City

of Kewanee and the discussions

with the City of Galesburg were not because ofthe boron issue. Presently, the

City of

Galva is actively involvedwith Prairie Ethanol, LLC,

in

developing a

Galva site for the construction of an ethanol plant. A feasibility study of the

proposed

site has been prepared for Prairie Ethanol by BMI International

Consulting,.a leading independent consUlting firm in the energy industry. The

results of

this study indicate that the City ofGalva is an excellent site for a new

ethanol plant. However, should the ethanol plant not locate in Galva, along with

their

need for large quantities ofwater, the situation would need to be re-

examined

from a "boron only" point ofview as a solution.

4.

A Site Specific Water Quality Standard

4.1

Relief Necessary

for Compliance

With the considerable costs associated with the aforementioned options, the City

of Galva has decided to petition the IPCB for a site specific water.quality

standard. A summary ofthe various aspects ofthis course of action is discussed

in the following sections.

, From the data provided in Figure 6, the City of Galva would need permission to

discharge from their existing sewage treatment plants an effluent flow with a

concentration ofup to 3 mg/Lofboron. This was the maximum recorded boron

concentration recorded

since September of2004.

stream flow

data was collected using the 7 Day 10 Year Low Flow Map (7QI0

Map) for the SpoonRiver Region published by the Illinois State Water Survey

(ISWS)

and the Illinois Streamflow Assessment Model available oriline from the

ISWS. The low flow stream discharges were assessed at the 7 day-l 0 year low

flow event (7QI0).

Using the minimum average monthly discharge data

from the STPs from 2006

(Figure 7), and assuming that the maximum recorded boron concentration was to

occur during a low flow period, the extents ofthe necessary reliefwere calculated

using the below equation

for each ofthe sewage treatment plants.

CBORON ADDED =[QSTP

X

CSTP]

I

[QSTP

+

QSTREAM]

Where:

CBORON ADDED = Final boron concentration in receiving stream. (mg/L)

QSTP'

= Discharge from sewage treatment plant (cfs)

CSTP

= Boron concentration in STP discharge (mglL)

QSTREAM

=

Water flow in stream during Q710 conditions (cfs)

4.2

Northeast STP Effluent Mass Balance

The lowest average monthly discharge for the Northeast STP for 2006 was 0.37

cfs. This was the average discharge for the month ofJuly 2006 (Figure 5).

During low flow periods (7QI0), the discharge from the Northeast STP would

receive

adequate dilution at the point where the South Branch ofthe Edwards

River

discharges and mixes with the Edwards River. It is at this point that the

boron concentration in

the stream would drop below 1

mg/L

during 7QI0

conditions.

CBORON ADDED

-.

Thus dilution would occur approximately 16.1 miles dO\VIlstream ofthe outfall of

the Northeast STP.

It should be noted that this is a worst case scenario, and during normal stream

flow conditions, dilution would occur much closer to the discharge of the

Northeast

STP.

...

Refer to Figure 12 for a map depicting the point of dilution for the Northeast STP.

4.3

Southwest STP Effluent Mass Balance

The lowest average monthly discharge for the Southwest STP for 2006 was 0.015

cfs. This was the average discharge for the month ofNovember 2006 (Figure 5).

During low flow periods (7Q10), the effluent from the Southwest STP would

. receive adequate dilution at the point just past where Mud Run discharges into

Walnut Creek. Again, it should be noted that this is a worst case scenario, during

nonhal conditions, dilution would occur closer to the discharge of the Southwest

STP.

CBORON ADDED =.[QSTP XC

QSTREAM]

CBORONADDED =[0.015 cfs x 3.0

[0.20 cfs]

CBORON ADDED

0.225 mglL

Thus dilution would occur approximately 7 miles from the outfall ofthe

Southwest STP.

Refer to Figure 12 for a map showing the point of dilution of the Southwest STP.

be found

Environmental Effects of a Site Specific Water Quality Standard

Nature of Boron

Boron is a naturally occurring element that is found in nature in compounds called

borates. Borates are found

in

the oceans, sedimentary rocks, coal, shale, and

some soils. Borates are naturally released into the environment fromthe oceans,

volcanic activity and other geothermal releases such as geothermal steam, and

weathering of clay-rich sedimentary rocks. Boron is also released, to a lesser

extent, from sources due to human activity.

Boron is an essential micronutrient for plants, with levels ofboron required for

optimum growth depending on the plant species. In some plants, there is but a

narrow range between boron deficiency and toxicity..

Hum

..

.

ans are primarily exposed to boron through food and drinking water. The

,

average daily intake of boron in the diet is about 1.2 mg per person per day and

the estimated average boron concentration in drinking water is between 0.1 and

0.3 mg/L. In humans and animals, most of the boric acid and borate are absorbed

from the gastrointestinal and respiratory tracts and excreted in the urine.

The effects of boron concentrations in excess ofthe current 1 mg/L discharge

standard

are discussed in great detail in previously granted petitions which are

discussed later in this report.

5.2

IEPA Stream Assessment

The South Branch ofthe Edwards River was rated by the IEPA

in

its

Integrated

Water Quality Report and Section 303(d) List (2006)

as "fully supporting" of

aquatic life and "fully supporting" offish consumption. It is "not supporting" of

primary contact use based on fecal coliform bacteria data. The source ofthe

bacteria concentrations is listed as "unknown".

The South Branch ofthe Edwards River does not discharge enough water to make

it a

viable source for potable water for any ofthe surrounding communities.

Mud Run and Walnut Creek were not assessed

ill

the 2006 edition ofthe IEPA's

Report. Neither stream is large enough to make it a source for potable water'

either.

5.3

Current Stream Usage

Research into the current uses of the affected waterways showed the streams were

essentially used for

drainage purposes and nothing more.

At the time ofthis report, there were 18 registered nurseries in Henry County.

None ofthese 18 nurseries are located close enough to the affected waterways to

utilize them for irrigation. Similarly, all 4 registered nurseries in Knox County

were not located near the affected streams. There are no golf courses. currently

located along the affected waterways.

Communications with Gary Clark, Director ofthe Office ofNatural Resources

(part'ofIDNR), confirmed that there are no authorized permits for structures to .

draw water from the streams.

Henry County Farm Bureau Director, Katie Boruff, checked with her county

Farm Bureau board members to see

ifthere were any specialty crops being grown

along

the South Branch of the Edwards River. No one was aware of any specialty

crops

that may require constant irrigation being grown along the affected

waterways.

Also, the Knox County Farin Bureau Director, Josh Gibb, also looked into any

specialty crops being grown along Walnut Creek and Mud Run

in Knox County.

To the best ofhis knowledge, there were no specialty crops being grown in that

area

ofthe county.

Considering

the

lack of current use oftlle effected streams and their relatively low

flows

it is reasonable to assume that a site specific water quality standard'will not

affect future stream usage.

Past Petitions Granted by the IPCB

Research into the requirements for a site specific water quality standard yielded

similar petitions filed to the IPCB for boron related discharges. Three

past

adjusted water quality petitions to the IPCB have exhaustively'exploredthe

toxicity

ofboron to humans, livestock, aquatic life, and plant life. In these past

petitions, reliefwas granted for boron concentrations much higher than the relief

requested

by the City of Galva. These past petitions are AS 94-9, AS 96-1, and

AS 96-8.

In AS 96 - 1, Exhibit 1, "An Assessment of an Adjusted Water Quality Standard

, for

the Kaskaskia River, Randolph County, Illinois; Baldwin Power Plant Ash

Pond Discharge (April, 1995y' by Illinois Power Company, goes into great detail

ofthe effects ofboron concentrations on the environment and wildlife. It was

concluded that the additional boron concentrations would have

nb

significant

adverse affects on the Kaskaskia River ecosystem.

Similarly, in

AS 96 - 8, Exhibit 1 "Technical Support Document, Adjusted Water

Quality Standard for Boron, Duck Creek Station, Fulton County, Illinois

(January, 1996)" by Hanson Engineers Incorporated, the effects

of high boron

concentrations on the environment are also discussed. Again,

the conclusion was

that

the high boron concentrations discharged by the Duck

C~eel(

Station would

pose

no additional risk to the local ecosystem. '

In each these previously granted petitions, reliefwas granted with boron

discharge concentrations

of11.0 mg/L (AS 94-9), 9.9 mg/L (AS

96~1),

and 4.5

mg/L (AS

96-8). The City of Galva is requesting reliefto a maximum of3.0

mg/L at the point of discharge for each sewage treatment plant.

Conclusion

In summary, removal of boron from a water source is not completely uncommon;

however, the majority of applications are industrial in nature as opposed to a

municipal wastewater or potable water. This is evident in the high upfront costs

associated wifu each ofthe explored alternative solutions.

Each ofthe treatment options have very complex issues regarding the disposal of

the resulting waste. As such, operation and maintenance costs can not be

accurately estimated at this time although they are expected to be significantly

high. These costs combined with the upfront construction, design, arid legal costs.

make these options impraCtical without significant financial assistance.

The alternative water supply sources are a considerable distance from the City of

Galva. The Galesburg to Galva option "has numerous technical, as well as

political issues that would have to be resolved, not to mention the expenses

associated with such a large scale pipeline system. The Green River Valley

option would require a significant expense

to determine ifit is even feasible,

which would be in addition to the cost to develop a well, or wells, and construct a

pipeline.

Considering the information obtained

from researching the issue, discussions with

persons in

the field, including personnel with the LE.P.A., a site specific water

quality standard seems the most feasible option at the current time. The adjusted

standard is expected

to yield no foreseeable negative impacts on the existing

environment.

It

is reasonable to assume with the source ofthe boron concentrations attributed to

the City'swater supply, that the City of Galva has been discharging boron

concentrations in excess ofthe current 1.0 mg/L limit since the drilling oftheir

first well in

1894. A site specific water quality standard would allow the City to

continue to discharge as it has for over the past 100 years.
