Hale Spring is situated at Plaistow, N. H., and is owned by the 

 Hale Spring Water Co. It was inspected November 26, 1907, sam- 

 ples directly from source being obtained for examination. The flow 

 was about 120 gallons per minute, with a temperature of 48 F. 

 Chemical analysis shows this to be a sodic, calcic, bicarbonated water 

 of the alkaline type. The hypothetical combination indicates that 

 approximately 54 per cent of the salts in solution are in the form of 

 bicarbonates of calcium and magnesium, 18 per cent of chlorid and 

 nitrate of sodium, and 8 per cent of sulphate of magnesium. The 

 sanitary alalysis shows only a small amount of ammonia and nitrates, 

 but the bacterial count is exceedingly high. Inspection of the prem- 

 ises failed to reveal any probable source of pollution. No advertised 

 analysis of this water could be obtained for purposes of comparison.
