Abstract
These files were derived from the map that Michael Jones created for identifying data available from the USGS NWIS site related to karst resources.
NWIS_Springs_With_Conductance.xlsx This file was posted by Laura Toran. This file summarizes a search of the USGS NWIS database for springs that have conductivity logger data.
NWIS_Sites_With_Nitrate.xlsx This file was posted by Laura Toran. This file summarizes a search of the online GIS maps for NWIS sites in carbonate terrain that have nitrate data and includes history of the datasets (length of record). The file contains all of the other water chemistry data available when nitrate is available. The file was created by downloading the attribute table when nitrate was the selected parameter.
NWIS_Sites_Nitrate_DataCounts.xlsx This file was posted by Laura Toran. This file summarizes the NWIS_Sites_With_Nitrate.xlxs file by counting how many nitrate records are available at each site and plotting the data. Most sites have only 1 or 2 data points but there are sites with up to 151 data points. This file was created using a python script described below.
ArcGIS_NWISData_Sort2.ipynb is a Python Collab (runs on google drive) that takes the file NWIS_Sites_With_Nitrate and sort out how much data is in each site. Although the script runs on google drive, it can be adapted for a Jupyter Notebook. If you run on Google Collab, you don't need to download Python onto your computer.
/WATER_QUALITY_GIS/AVERAGES: This shapefile is a shapefile that contains an attribute table with the averages of selected water quality parameters by site. For example, the attribute table contains columns for water quality parameters such as Calcium, specific conductance, Magnesium, etc. The table has the averages at each site for each of the water quality parameters.
/WATER_QUALITY_GIS/WQ_COUNT: This shapefile is a shapefile that contains an attribute table with the number of samples that exist for selected water quality parameters by site. For example, use "Select by Attributes" to find sites that have Calcium measured over x number of times.
/WATER_QUALITY_GIS/States.shp: Shapefile of the US states
