HISTORY AND LOCATION
The USEPA Episodic Response Project (ERP) was conducted from 1988 to 1990
to evaluate the occurrence and biological consequences of episodic acidification
in northeastern U.S. streams. When the ERP concluded, the ALSC continued sampling
of three ERP streams on a weekly interval as part if its long term monitoring
program to determine responses from changes in atmospheric deposition. The
study streams, Buck Creek, Bald Mountain Brook, and Fly Pond Outlet, are all
located in the southwestern quadrant of the Adirondack Park.
SAMPLING DESIGN
Surface grab samples are collected from streams in deionized water-rinsed
polyethylene bottles.
Each week samples are analyzed for lab pH, air-equilibrated pH, acid neutralizing capacity and specific conductivity. In addition, once each month samples are analyzed for the following additional parameters: trucolor, inorganic aluminum, organic aluminum, total dissolved aluminum, total monomeric aluminum, calcium, chloride, dissolved inorganic carbon, dissolved organic carbon, flouride, potassium, magnesium, sodium, ammonia, nitrite, silica and sulfate.
Concentration values are reported in mg/L ( instrument units ) for all parameters,
with the following exceptions:
Specific conductance µ siemens/centimeter (µ S/cm)
pH pH units.
Color platinum-cobalt units PtCo
Aluminum µ g/L
Total dissolved, total monomeric and organic monomeric aluminum are analytically
derived. Inorganic monomeric aluminum is calculated by subtracting organic
monomeric from total monomeric aluminum.

DATA ACCESS
Public access via the website www.adirondacklakessurvey.org Data represents
samples taken from June 1992 to December 2004. Updates to the data set are
planned in 2-3 year increments, following publication of current trend analyses.

DATA ARCHIVE
The data archive is comprised of three files:
ALSC.Streams.2004.XLS Microsoft Excel™ spreadsheet that contains stream analytical data by sample and parameter. Detection limits are included on the second sheet of this spreadsheet.
ALSC.Streams.2004.CSV CSV Comma delimited ASCII file containing stream analytical data organized by sample and parameter.
STREAM_OVERVIEW This document.
EXPLANATORY NOTES
1. Missing data values are referenced by nulls ( blank space ). Note: Analysis
of the full complement of chemical parameters is conducted only once each
month. Parameters not analyzed on the interim sample dates are indicated by
null values.
2 Data that do not meet the minimum charge balance criteria as defined by the EPA’s LTM Data Users Guide are flagged in the flag column.
3 Lab pH is stirred and unsparged with a seven-day holding time. Air-equilibrated pH is stirred and sparged for five minutes with a carbon dioxide / nitrogen mix and carries a seven-day holding time.
DETECTION LIMITS
Detection limits are presented on the second sheet of the MicroSoft Excel
file contained in the archive.
DATA UPDATE FREQUENCY
The data set is updated every two to three years following ALSC’s QA/QC
procedure and publication of updated trend analysis.
Publications using data from the Adirondack Long-Term Monitoring Program
must include the following paragraph:
Some data used in this publication were obtained by cooperators of the Adirondack
Lakes Survey Corporation's (ALSC) Long-Term Monitoring ( LTM ) Program. This
publication has not been reviewed by the ALSC, nor has it been reviewed by
the researchers or personnel of ALSC's cooperators. The LTM Program is operated

Authority and the New York State Department of Environmental Conservation,
Division of Air Resources, with additional funding from the US Environmental
Protection Agency.
