Click to hide Water-Year Summary instructions and information
  • Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
  • For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
  • For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
  • For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
  • Not all sites have reports available for every water year.

USGS Water-Year Summary 2023
425311070535801 NH-SGW 65
Sand and gravel aquifers (glaciated regions)
Ice-Contact Deposits, Pleistocene
LOCATION - Lat 42°53'12.00", long 70°53'57.00" referenced to North American Datum of 1983, Rockingham County, NH, Hydrologic Unit 01060003, is located in the Riley Wellfield at the Seabrook Water Department in Seabrook. Owner: Town of Seabrook.
REVISIONS HISTORY -

pH record was deleted from 2014-10-01 to 2015-01-12 due to failing probe. The period had originally been retained but obvious outlier when seen over the entire record through 2018.

Specific Conductance record from 2014-07-01 to 2014-11-13 was adjusted. One Set 2 correction was removed during that period and another was adjusted to correct for an erroneous calibration.

Dissolved Oxygen record from 2017-06-13 to 2018-02-12 was adjusted by removing the initial high values after the pump came on.
