BAILEY AND BAKTOW : CITY WATER-SUPPLIES. 243 



The analysis shows that the untreated water is better at Che- 

 topa than at Oswego. This may be partly due to dilution of 

 the water by Labette creek, and partly to sedimentation and 

 oxidation. 



In order to more fully understand the water of the Neosho 

 system, a mineral analysis was made by Mr. C. F, Gustafsen 

 of a sample taken in Doctor Lardner's office in Chanute. The 

 following is the resul : 



Grams per liter. 



IONS. 



Calcium (Ca.) 0756 



Magnesium (Mg) 0004 



Chlorin (CI) 0085 



Sulfuric acid ion (SO4) 0491 



Silicic acid ion (SiOz) 0796 



RADICALS. 



Calcium oxid (CaO) 1058 



Magnesium oxid (MgO) 0007 



Ferric oxid (Fe203) / rvoq < 



Aluminum oxid (A]203j ) 



Chlorin (CI) 0085 



Sulfuric anhydrid (SO3) 0409 



Silicic anhydrid (Si02) 0796 



The above onstituents may be hypothetically combined as 

 follows : 



Grams Grains 



per liter. per gallon. 



Sodium chlorid (NaCl) 0140 .818 



Sodium sulfate (Na2S04) .0577 3.370 



Calcium bicarbonate (CaH2(C03)2) 1783 10.414 



Calcium sulfate (CaSOj) 0144 .841 



Magnesium bicarbonate (MgH2(C03)2) 0015 .088 



Oxids of iron and alumina 0294 1.717 



Silica (Si02) .0796 4.649 



Totals 3749 21.897 



This analysis shows the water to be of excellent quality, as 

 far as the mineral matter is concerned. The total solid matter 

 (21.897 grains per gallon) is not as high as that found in many 

 of the other rivers of the state. On this account, then, the 

 water is well adapted to domestic and boiler use. The chief 

 mineral substance present in the water is calcium carbonate, 

 and^that can be readily removed by treatment with a little milk 

 of lime or by the use of washing soda.
