Questions were also raised as to whether department employees were being asked to handle too many tests. Martin testified the department conducts between 19,000 and 25,000 drug tests a month.
"The amount of (urine analysis) tests taken at our labs is ridiculous," Martin told the court. "It's ridiculous to expect a person to take that many tests."
Another department employee who testified during Thursday's hearing told the court he had been tasked with administering between 60 and 100 tests in a single day.
