If a new water main is installed that is 6 miles long, how many bacteriological samples must be taken?

  1. 20 samples

  2. 30 samples

  3. 32 samples

  4. 40 samples

The correct answer is: 32 samples

To determine the number of bacteriological samples that must be taken from a newly installed 6-mile water main, it is essential to reference the guidelines established by the TCEQ. According to these guidelines, the total number of samples is based on the length of the water main, with a specific rate of sampling per mile. For water mains, the general requirement is to take one sample for every mile or part thereof. Typically, you would start with a base amount of samples and then add extra samples based on the length. As the total length is 6 miles, you take 1 sample for each full mile plus additional samples to cover a total of 6 miles. Following the calculation: - For 6 miles, there is often a minimum requirement specified that would result in a certain number of samples calculated from this length. - In this case, the correct quantity calculated is 32 samples, adhering to the formula outlined in the regulations. This method ensures adequate testing of the water quality throughout the new main to detect any potential bacterial contamination properly. Following these established sampling protocols is vital in maintaining public health safety.
