DISCUSSION OB' ANALYSES.

These three reports show Sheboygan mineral water to be a very pure water and 

 much better than your report would indicate. This difference is very readily traced 

 to some trouble we were having last year with the pipe line which supplies our plant 

 with the mineral water. This pipe line is about one-fourth of a mile in length and 

 leaked a few times last year, and was undoubtedly leaking at the time the water was 

 bottled which you examined. This pipe line has been in for fifteen years, but as 

 soon as the ground is in condition we will lay new pipe, so as to avoid any possible 

 pollution hereafter. However, we have detected no leakage in the pipe since it was 

 repaired December 1. 



The mineral water flows from an artesian well 1,475 feet deep, with natural pres- 

 sure of 52.5 pounds to the square inch. This well is piped with a copper pipe which 

 extends 400 feet into the rock, and is securely fastened to the rock at the foot with a 

 heavy expansive packing. This seals the pipe securely, and no surface water can 

 possibly enter the well. In justice to Sheboygan mineral water, we would request 

 you to make another examination of the same. 



Inclosed analyses. 



In view of the explanation given in the above letter, another sample 

 of the water was purchased on the open market and subjected to a 

 sanitary examination, with the following results: 



Parts per 

 million. 



Free ammonia 0. 10 



Albuminoid ammonia 02 



Nitrites Considerable. 



Nitrates None. 



This analysis shows a considerable reduction in the albuminoid 

 ammonia figure, which was the only one that was at all unsatisfactory in 

 the analysis as originally made. The considerable quantity of nitrites 

 has no significance in an artesian well water, such as is described above. 



MANITOU TABLE WATER (No. 1221 I. & W.). 



The advertised and Bureau of Chemistry analyses of this water 

 agree very satisfactorily with each other with one exception, i. e., 

 lithium, the Bureau only finding 0.23 part per million, while, the 

 advertised analysis claims 2.3 parts per million. 



RUBINO HEALING SPRINGS WATER (No. 1222 I. & W.). 



The same may be said of this water as was said for the Manitou, 

 except that the Bureau analysis shows only a spectroscopic trace of 

 lithium, while the advertise^ analysis gives 0.91 part per million,
