This well has thrown important light on the water horizons for the 
western corner of Burlington County. The waters are in the mid- 
Matawan beds at 80 feet, in the basal Matawan beds at 125 feet, in the 
mid-Potomac beds at 280 feet, and apparently in the basal Potomac 
beds at 370 feet. Excepting the deepest, these waters are also found 
in the Moorestown well, and they also occur in the other wells, as shown 
in section 2, PI. III. 
Marlton region, Burlington County. — There are many wells in the 
vicinity of Marlton, and the greater number of them draw an abundant 
water supply from the Redbank horizon. They are described in con- 
siderable detail in the New Jersey reports, and especially by Mr. Wool- 
man in the report for 1894, where their relations are also shown in a 
detailed cross section. The following notes are condensed from these 
reports : 
A bored well at the house of Mr. Joseph Evans, 1J miles south of 
Marlton, has a depth of 155 feet and yields 20 gallons per minute. 
The water rises to within 40 feet of the surface and is of good quality, 
and from the fossils found it is judged to come from the sand bed 
underlying the Lower Marl bed. The well was first sunk to a depth of 
380 feet without getting water, as it was driven through this sand layer 
without proper testing and into beds of upper Matawan clay marls, 
which have usually failed to yield a supply of good water. 1 
A well was bored in 1884 in Marlton for O. B. Chew. Its depth is 86 
feet and its diameter 5| inches. It is sunk through the Middle Marl 
bed into a sandy layer of the Redbank formation. The following record 
is given : 
Feet. 
0-20 loam and gravel. 
20-26 black marl. 
26-46 greensand marl. 
46-59 chocolate marl, with a thin, strong crust near its middle and at 
its base. 
59-83 hard black sand, which gradually becomes white below. 
83-86 hard rock or bowlder. 
The water rose to within 24 feet of the surface. Quality is good. 
Temperature, 52£°. ' 
Two miles west of Marlton, on the farm of Mr. Ellwood Evans, there 
are several wells with depths of about 30 feet, which obtain water sup- 
plies from the Redbank sands.
