DATA SET ABSTRACT 3.1 Abstract of the Data Set The primary function of the stream water chemistry samples is to determine acid-base status, trophic state, and classification of water chemistry type. Stream water stored in Cubitainers was used to measure major cations and anions, nutrients, turbidity, and color. Sealed syringe samples are analyzed for pH, dissolved inorganic carbon, and monomeric aluminum species believed to be toxic to fish under acidic conditions. Waters samples are collected in sealed syringe to minimize contact with the atmosphere. The pH, dissolved inorganic carbon, and aluminum present in the water sample will all change if the stream water equilibrates with atmospheric carbon dioxide. 3.2 Keywords for the Data Set Sodium, alkalinity, acid neutralizing capacity, specific conductance, dissolved organic carbon, bicarbonate, potassium, magnesium, ammonium, nitrate, total nitrogen, pH, total phosphorus, total suspended solids, turbidity, absorbance, water chemistry, eutrophication 4. OBJECTIVES AND INTRODUCTION 4.1 Program Objectives The Environmental Monitoring and Assessment Program (EMAP) was designed to periodically estimate the status and trends of the Nation's ecological resources on a regional basis. EMAP provides a strategy to identify and bound the extent, magnitude and location of environmental degradation and improvement on a regional scale based on a probability-based statistical survey design. 4.2 Data Set Objective This data set is part of a demonstration project to evaluate approaches to monitoring streams in EMAP. The data set contains the results of field analysis of chemistry from a water column sample taken during spring low flow. 4.3 Data Set Background Discussion Water chemistry in streams is analyzed for two purposes. First, to understand the chemical habitat within which biota must exist so that we can understand the biological potential of the system and second, to evaluate the chemical quality of the water for the purposes of determine the potential stresses to which the biota are exposed. 4.4 Summary of Data Set Parameters Water chemistry parameters from the field are reported for one sample taken at the midpoint of the selection stream reach. These include: pH, disolved oxygen, water temperature, and conductivity. 5. DATA ACQUISITION AND PROCESSING METHODS 5.1 Data Acquisition 5.1.1 Sampling Objective To obtain a single grab sample of stream water for the purposes of chemical analysis during a sampling window from June through October. 5.1.2 Sample Collection Methods Summary A grab sample was taken below the surface using a 500 ml. beaker and then transferred to a 4-L Cubitainer, and dissolved oxygen, conductivity, and temperature were measured using a multi-function meter according to the protocols identified in Lazorchak et.al (1998). 5.1.3 Sampling Start Date June 30, 1997 5.1.4 Sampling End Date October 15, 1997 5.1.5 Platform NA 5.1.6 Sampling Gear 500 ml beaker, dissolved oxygen/temperature meter with probe, conductivity meter, 500 mL plastic bottle, field themometer, 4-L cubitainer, 60 mL plastic syringes and valves. 5.1.7 Manufacturer of Instruments YSI Incorporated, Yellow Springs, OH - Model 85 Handheld Oxygen, Conductivity, Salinity, and Temperature System Operations Manual.
