CHAPTER VII
WATER SUPPLY

A. General

I

I

Fractured bedrock constitutes t~e principal aquifer from which water sources

for the Brook Forest Water District are obtained. Wells drilled through granite

formations intercept water from fractures or joint systems in the study area.

Due to the variability of water rec~arge to the fractured rock, the depth

and water yield of each well differs significantly. The yields of wells are

determined by the number and size of recharged fractures intercepted by the well.

Alluvial aquifers, composed of sand and gravel deposits, that could be used as

a ground water source are scarce in the study area.

B. Existing Well Data

I

At the present time, four wells are supplying water to the district's

system and are designated by the owners as Well Numbers 1, 2, 3 and 4. The

approximate locations of the wells are shown on Fi~ures-6 and -7. The four

wells are capable of producing the 28 gpm volume of water decreed to the dis-

trict through the present water rights. Output of the wells are monitored by

meters located at the well's discharge points. The maximum continuous yield of

each well varies significantly from 0.5 gpm to 25 gpm. Yields and other basic

information related to the four wells are presented in Table-4.

Until recently, the water supply for the district has been inadequate to

meet the demand on numerous occasions. Water demands, within the district,

have exceeded the water supply capability of the the system. With the addition

of Well No.4 in January of 1979, the district is presently capable of supplying

the present demand.
