What does IDEXX System select for? What is the Total Coliform Rule?

IDEXX is used to identify fecal coliform bacteria in the water, to test environmental water safety.

How much bacteria is safe to have in the water for human use. Above the threshold the water is no longer safe.

Homework Answers

Answer #1
  • The IDEXX system is used to identify the coliform bacteria in the water in order to test the water safety for organisms.
  • The total coliforms are not likely to cause diseases but their presence indicates that the water supply may be contaminated by more harmful organisms.The rule requires all public water systems (PWSs) to monitor for the presence of total coliforms in the distribution system at a frequency proportional to the number of people served.
  • The permissible limit to have bacteria in the water for human use is 0 colony forming units per 100 mm or less than 1 colony forming units per 100 mm or is non detectable colonies.

Water samples are taken from water used for cooling as it is being discharged from a power plant into a river. It has been determined that as long as the mean temperature of the discharged water is at most 150 degrees Fahrenheit, there will be no negative effects on the river ecosystem. To investigate whether the power plant is in compliance with regulations that prohibit a mean discharge water temperature above 150 degrees, a scientist will take 50 water samples...

A breathalyzer test is used by police in an area to determine whether a driver's blood alcohol content (BAC) is above the legal limit. The device is not totally reliable: 3.9% of drivers who have not consumed too much alcohol give a BAC reading from the breathalyzer as being above the legal limit, while 11.8% of drivers who have consumed too much alcohol will give a BAC reading below that level. Suppose that in fact, 5.8% of drivers have consumed...
