### Knowledge Review

Please review the scenario below and answer the related question on the following page.

The utility emergency manager at the Clear Valley Water Treatment Plant receives notification that a train tanker car spilled upstream of the drinking water treatment plant intake; the drinking water intake is shut down.

The utility emergency manager needs to find out if the water is safe or whether a "do not use" order should be issued. He considers the following information:

- The water utility laboratory is undergoing renovations and cannot perform chemical analyses.
- Good Chemistry, Inc., where the utility normally sends their compliance samples, is short-staffed and will be unable to process a large number of samples, but can process a limited number of samples if the state laboratory needs assistance.
- The drinking water utility has received analytical support from their state laboratory in the past and usually contacts them first when they need support.
