From:____Bruce

Introduction

This

technical

memorandum

outlines

a

groundwater

monitoring

program

for

the

above-mentioned

facility.

Included

are

background

materials, monitoring

well

details,

and

a

description

of

a

conceptual

plan

for

monitoring

groundwater

at

this

facility.

A

final

in

the

Pond

D

Closure

Plan.

The

final

plan

will

include:

procedures

for

groundwater

sampling,

sample

preservation

and

shipment,

analytical

methods,

quality

assurance

and

quality

control,

recordkeeping,

and

analysis

and

Background

Ameren

Energy

Generating

Company

(AEG)

operates an impoundment system

with

five

ponds

at

the

Hutsonville

generating

station

(Figure

1).

Ponds

A

and

B

are

lined

impoundments

that

currently

receive

coal combustion

by-product

(CCB),

Pond

C

is

a

lined

impoundment

that

receives

stormwater

runoffand

other

flows

from

the

plant,

and Pond

D

is

an

unlined

impoundment

that

formerly

received

CCB

and

is

now

removed

from

service.

The

fifth

pond

receives

bottom

ash.

Ponds

A,

B, C,

and

the

bottom

ash

pond

are

permitted

under

the

1EPA

Bureau

of Water's

Water

Pollution

Control

program.

Pond

D,

which

was

formerly

permitted

under

the

Water

Pollution

Control

program,

will be

closed

under

the

Bureau

of

Land's

Solid

Waste

program.

Site

Hydrogeology

The

impoundments

are

underlain

by

two

water-bearing

units

separated

by

materials

that

have

low

hydraulic

conductivity

(shale

bedrock

or

silts

and

clays).

The

upland portion

of

the

power

plant

property

(the

site),

and

the

western

portion

of

Pond

D,

are

underlain

by

a

thin

(less

than

20

feet

thick)

layer of

sand-rich

soil,

which

is

underlain

by

Pennsylvanian-age

sandstone

and then

shale

(Figure

TECHNICAL

MEMORANDUM

Section

A-A').

The

lowland

portion

of

the site

and

eastern

portion

of

Pond

D

are

underlain

by

90

feet

of

alluvium

in

the Wabash

River

bedrock

valley.

The

upper

20

feet

of alluvium

is

fine-grained,

primarily

composed

of

silt

and

clay

with

thin

sand

lenses,

while the

lower

70

feet

is

coarse-grained,

consisting

of

sand and

gravel.

Every

boring

drilled

over

the

alluvium

encountered

the

fine-grained

deposits,

and

on-

site

borings

that

extended

to the

underlying

sand and

gravel

(SB 101, SB

102,

MW7D, MW14,

MW115,

and MW121)

encountered

19

to

25

feet

of

these

deposits (Figure

2,

Cross-Section

B-B').

Pennsylvanian-

age

shale underlies

the

alluvium.

The

shallow

upland

sand

and

sandstone,

and

sand

lenses

in

the

fine-grained

alluvium are referred

to as

the

upper

migration

zone,

and

constitute

the

uppermost

aquifer at

this

site.

The

coarse-grained

alluvium

is

referred to

as

the deep

alluvial

aquifer.

The

shale

underlying the

upland

sandstone

and

the silts

and

clays

of

the

fine

grained

alluvium

separate

the

upper

migration

zone

from

the

deep

alluvial

aquifer.

Groundwater

flow

was

mapped

for four

consecutive quarters

in

2003-2004, and

again

in

2007.

During

the

2003-2004

period,

depth

to

water

readings

for

all

of

the

upper

migration

zone

and

one

of

the

deep

alluvial

aquifer

maps

were

not

collected

on

the

same

day. While

this

discrepancy

did

not

appear

to

change

map

depictions

of

the

overall

direction

ofgroundwater flow,

it

affected

relative

readings

between

wells. Therefore,

the

second

set

of

drawings

was

produced

using

data

collected

after

the

plant

initiated

same-date measurements

beginning

in

2006.

All

maps

show

that

groundwater

flow

in

the

upper

migration

zone

and

the deep

alluvial

aquifer

is

eastward toward

the

Wabash

River

(Figures

3

and

4).

Groundwater

Quality

AEG

has

performed

groundwater monitoring

at

this

facility

and

found

concentrations

of

boron

and

sulfate

higher

than

Class

1

standards

in

Pond

D

monitoring

wells

screened

in

the

upper

migration

zone.

No

concentrations

in

the

deep

alluvial

aquifer

exceed

Class

1

standards.

Sulfate

and

boron

are

mobile

indicator

parameters

for

coal

ash

leachate.

Impacted

Pond

D

monitoring

wells

in

the

upper

migration

zone

are

MW-6,

MW-7, MW-8,

and

MW-11

R.

The

fine-grained

alluvial

deposits overlying

the deep

alluvial

aquifer

occur

over

an

elevation

range

that

overlaps

the

upland

shale

(Figure

2-1,

Cross-Section

A-A'),

combining

to

form

a

confining

layer

that

restricts

vertical

migration

ofgroundwater.

The

efficacy

of

the

confining

layer

is

supported

by

the

concentration

data,

because

the

only

ash

leachate

impacts

observed

in

the

deep

alluvial

aquifer

are

highly

localized,

and

at

concentrations

lower

than Class

I

standards

and

much

lower

than

in the

upper

migration

zone,

despite

the

fact

that

Pond

D

was

first

placed

in

service

40

years

ago.

AEG

currently

has

a

groundwater

monitoring

program

for

Pond

A.

The

Pond

A

monitoring

program

is

designed

for detection

of

a

release from

that

lined

pond.

It

consists

of five monitoring

wells

completed

in

the

upper

migration

zone,

and

five

parameters

with listed

limitations,

on

a monthly

basis

(Table

Pond

is

summarized

in Table

MW-1

and

MW-10

provide upgradient

data for

the

upper

zone.

There

are

no

suitable

locations for

deep

alluvial

aquifer

background

monitoring

points,

because

the

Wabash

River

overlays

the

western

edge

of

the

deep

alluvial

aquifer

north

of

Pond

D.

Analytical

Constituents

Boron

and

sulfate

are

the

primary

indicators

of coal

ash

leachate.

These

constituents are

persistent,

mobile,

and

typically

present

in

elevated

concentrations

in

coal

ash

leachate.

Additional

monitoring

of

pH,

specific

conductance,

groundwater elevation,

and

monitoring

well

depth

will

be

completed

during

each

sample

event.

In

addition

to the

field

parameters

and

ash

indicators,

inorganic

constituents with

Illinois

Class

1

groundwater

quality

standards

will

be

analyzed

at least

once

each

year

until

a

demonstration

is

made

that

the

constituents

can

be

removed

from

the

monitoring

program.

Schedule

Groundwater

will

be

sampled

on

a quarterly

basis

for

the

first

five

years

after

closure.

The

frequency

of

groundwater

sampling

will

be

reduced to

semi-annual

sampling

upon

a

determination

of

all

of

the

following:

•

Five

years

after

closure;

•

That

monitoring

effectiveness

has

not

been

compromised

by

the

reduced

frequency

of

monitoring;

•

That

sufficient

quarterly

data has

been

collected

to

characterize

groundwater;
