﻿HYDROLOGY

  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 
  Avestern 
  New 
  

   York. 
  The 
  study 
  at 
  Rochester 
  can 
  be 
  duplicated 
  almost 
  anywhere 
  

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

  

  duality 
  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
