The Arethusa Spring is located at Seymour, Conn., and is owned 

 and operated by the Arethusa Spring Water Co. Inspection of the 

 spring was made December 6, 1907, samples directly from source 

 being obtained for examination. The flow is approximately 5 

 gallons per minute, with a temperature of 49 F. Chemical analysis 

 shows this to be a lightly mineralized, sodic, calcic, bicarbonated 

 water of the alkaline type. The hypothetical combination indicates 

 that approximately 44 per cent of the salts in solution are in the 

 form of bicarbonates of calcium and magnesium a^id approximately 

 13 per cent of sulphate of sodium. The sanitary analysis shows 

 only traces of free ammonia and small quantities of albuminoid 

 ammonia and nitrates, which, with an absence of bacteria, indicates 

 organic purity. Inspection of the premises failed to reveal any 

 probable sources of pollution. The advertised analysis made in 1894 

 agrees fairly well with the analysis made by this bureau.
