HYDROLOGY OF NEW YORK 



861 



As further illustrating the quality as well as the quantity of 

 water obtainable for municipal water supplies in western New 

 York, the villages of Brockport and Holley have for a number 

 of years had insufficient supplies from dug wells — the same thing 

 is true of the village of Albion. The village of Medina is stated 

 to be supplied from the Erie canal, although some pretence is made 

 of taking the supply from a well, and the city of Lockport has 

 never had any supply except from the Erie canal. At all these 

 places the supply of pure, potable water is scanty and of high 

 value — the same thing is true generally throughout western New 

 York. The study at Rochester can be duplicated almost anywhere 

 in the region from Seneca lake to the western limits of the State. 



Quality of Water in the Vicinity of Medina 



In order to show some facts in regard to the quality of water 

 near Medina, the following analyses are herewith included. (1) 

 is from a disused shallow well, one mile south of Shelby Center; 

 (2) is from a bored well not far from the preceding, taken after 

 a few days pumping. These two analyses were made by Prof. 

 Herbert M. Hill, of Buffalo; (3) is also from a bored well, in the 

 same locality, and (4) is from the Oak Orchard creek, a mile 

 south of Shelby Center. The two latter were made by Fred R. 

 Eilinger, chemist of the Rochester Health Department:
