The purpose of this data table is to document the sample ID, latitude, longitude, location description, pH, and cation and anion chemistry results of water samples near Chiginagak volcano as referred to in this report:Schaefer, J.R., Scott, W.E., Evans, W.C., Wang, Bronwen, McGimsey, R.G., 2011, Summit crater lake observations, and the location, chemistry, and pH of water samples near Mount Chiginagak volcano, Alaska: 2004-2011:Alaska Division of Geological & Geophysical Surveys Report of Investigations RI 2011-6.

Data sources used in this process:
Attribute values listed in the final table were checked for consistency by cross-referencing field data sheets and laboratory chemical results as well as plotting the locations and attributes in a GIS.
Horizontal positions (latitude and longitude) were determined with handheld GPS receivers.Although in most cases latitude and longitude are given in decimal degrees to 5 decimal places, the accuracy of this position is likely more coarse, as a GPS station may have been taken 20 meters or more from the exact site in the stream where the water sample was actually taken. Users reoccupying the sampling sites should use care to read the location description information to determine what stream corresponds to what sample site, especially near confluences.
At the time of writing, some pH values and chemical data were not processed for samples collected in 2011. When these data become available, they will be provided as an addendum to this table.Conductivity, pH, temperature, and chemical samples were not collected at all sites.At some sites, only pH paper was available, thus a range of pH is given versus sites where pH was taken with a digital pH meter. In the latter case, pH is given to the nearest 1/10th.
Positional accuracy was checked by plotting locations in a GIS and comparing placed points with topography and map attributes. Chemical values and pH were also plotted in GIS and compared in time series to ensure logical accuracy.
