SOME IOWA WATERS. 
BY NICHOLAS KNIGHT. 
1. The Springville Water Supply. 
The source of the supply is an artesian well one hundred and fifty feet in 
depth. The water is quite free from organic contamination, and quite soft 
for an Eastern Iowa water. The numbers express the different amounts in one 
million parts of the water. 
Total Solids 240.0 
CaCOs 101.4 
MgCOs 93.6 
CaSOi 20.4 
Fe203 and AI2O3 19.4 
Sr02 0.4 
NaCl and KCl 4.8 
CO2 free and partly united 68.0 
Free ammonia 0.05 
Albuminoid ammonia 0.07 
Nitrates 0.10 
2. The Spring at the Palisades. 
This is a well-known spring at the Palisades on the Cedar river. The figures 
express great freedom from organic contamination. The low temperature of the 
water indicates a deep-seated origin. The taste is agreeable and altogether the 
spring is a valuable one. 
Total Solids 316.4 
CaCOs 175.8 
MgCOa 97.2 
Fe203 and AI2O3 6.8 
Si’Oa 9.8 
NaCl and KCl 26.8 
CO2 168.00 
Free ammonia 0.012 
Albuminoid ammonia 0.00 
Nitrates 0.634 
3. The Lis'bon Water Supply. 
The supply comes from two sources; A spring twenty-four feet in diameter 
ana twenty-four feet in depth; and from a well one hundred and forty-four feet 
deep. The water is pumped from the well into the spring, and thence into a 
standpipe, from which the town is supplied. The first analysis is of the water 
direct from the main, which is, therefore, a mixture of the spring and well water.
