Kills and Spills Team (KAST)

Thirty Years of Investigating Fish and Wildlife Kills and Pollution in Texas

Methods

In 1997 the Kills and Spills Team worked to enter over 4500 historical kill and spill incident reports into a custom-designed Microsoft Access database application known as PRISM (Pollution Response Incident and Species Mortality). The type of information stored in PRISM is listed in Table 1.

Using Microsoft Access’ built-in query functions, the PRISM database was searched for the period of record (1958-1997) to categorize and summarize kill and spill reports. Some data were exported to Microsoft Excel for manipulation and charting.

Table 1. Selected data fields in the PRISM database.
