Katahdin Spring is located 2 miles from Lexington, Mass., and is 

 owned and operated by the Katahdin Spring Water Co. It was 

 inspected November 30, 1907, samples directly from source being 

 obtained for the examination. The flow was approximately 10 

 gallons per minute, with a temperature of 48 F. Chemical analysis 

 shows this to be a highly mineralized, calcic, sodic, nitrated, muriated, 

 bicarbonated water of the alkaline-saline type. The hypothetical 

 combination indicates that approximately 43 per cent of the salts in 

 solution are in the form of the nitrates of sodium, potassium, and 

 magnesium, 12 per cent of chlorid of magnesium, and 23 per cent of 

 calcium bicarbonate; also small quantities of calcium chlorid. The 

 sanitary analysis shows only small amounts of albuminoid ammonia 

 and faint traces of nitrites. The nitrates are, however, unusually 

 high, and while the bacterial count is low, gas-forming organisms 

 were found in 1-cc quantities. These facts indicate that the water 

 is of doubtful purity, while inspection of the premises showed the 

 possibility of contamination of the spring during freshets or wet 

 weather by surface drainage. No advertised analysis of this water 

 could be obtained for purposes of comparison.
