pumping station that spread over 20 acres in California that was used to pump natural gas through pipes to people across the state. They used a chemical called chromium XI to prevent the rusting of the pipes. The chemical runoff was disposed of in unlined wastewater ponds (Sharp‚ 2000). In 1987‚ during a routine check PG&E found that the chromium had leaked into the water supply and in December they reported their findings to the California Regional Water Quality Control Board. The board then ordered

DISCUSSION: Qualitative analysis is used to determine the presence of cations or anions present within a sample and their impurities. Information known‚ such as chemical and physical properties‚ about cations and anions can be used to determine what steps should be used to separate the sample into one‚ specific ion. Qualitative analysis involves forming and decomposing complex ions. Qualitative tests are very sensitive‚ allowing to detect a very small amount present in sample. Due to sensitivity
