The Poland Mineral Spring is located in South Poland, Me., and is 

 owned and operated by the firm of Hiram Ricker & Sons. The 

 waters from this spring have been sold for many years, the spring 

 having had considerable local reputation as early as 1860. The 

 water is used locally and a large quantity is bottled for sale. The 

 spring was visited on November 15, 1907, samples directly from source 

 being obtained for examination. The flow at the time of inspection 

 was approximately 7 gallons per minute, with a temperature of 

 46 F. The chemical analysis shows this to be a moderately mineral- 

 ized, calcic, bicarbonated water of the alkaline type. The hypo- 

 thetical combination indicates that approximately 67 per cent of 

 the salts in solution are in the form of bicarbonates of calcium and 

 magnesium with 8 per cent of sodium chlorid, 5 per cent of sodium 

 nitrate, and 4 per cent of sodium sulphate. The sanitary analysis 

 shows small amounts of free and albuminoid ammonia, low nitrates, 

 and low bacterial count, which indicates organic purity. Inspection 

 of the premises failed to reveal any probable sources of pollution. 

 The advertised analysis differs somewhat from the analysis made 

 in this bureau, the mineralization of the spring having apparently 

 increased since the advertised analysis was made in 1875.
