The most common means for summarizing any kind of monitoring data are tables, graphs, and maps. Charts, graphs, and maps display data in a way that illustrates the story behind the numbers. When designed well, these visual presentations of monitoring data quickly and powerfully depict patterns such as increasing or decreasing trends over time, seasonal variability, impacts of pollution sources, improvement (or lack of it) after restoration projects, upstream-to-downstream trends and changes, relation to land use and population, and comparisons between watersheds. The GWW online database provides monitors and the general public with ways to retrieve and analyze data in all three options mentioned above. These tools help monitors and others understand and interpret the data, as well as for presenting data to a variety of audiences.
Graphs or charts are often the simplest way to summarize large amounts of data. Nonspecialists can usually understand a graph with the baseline (x-axis) representing time and the y-axis representing the water quality variable(s). These graphs can quickly elucidate seasonal and multiyear trends. The GWW online database displays monthly water monitoring information such as E. coli concentrations as line or bar graphs.
To see the data from a given site, you may search that site selecting either by the watershed or by the political boundary in which that site is physically located. In the case of Kenya, the political divisions are: County >Division >Location. At the end of your search you will see a list of sites with a 12-digit number on the left column, the site code where you select the one of your interest and display the data for that monitoring site.
