7. Which of the following is NOT a recommended sampling site for total coliform analysis? (10 Points) A) Outdoor faucets B) Faucets connected to cisterns C) Kitchen sink faucets D) Faucets with new plumbing 8. What is the recommended temperature for storing samples collected for asbestos analysis? (10 Points) A) leqslant 4^circ C B) leqslant 10^circ C ) C) leqslant 20^circ C D) leqslant 30^circ C

7. The correct answer is D) Faucets with new plumbing.For total coliform analysis, the recommended sampling sites are typically outdoor faucets, faucets connected to cisterns, and kitchen sink faucets. These sites are more likely to be exposed to potential sources of contamination, such as runoff from the surrounding environment or cross-connection with non-potable water sources. Faucets with new plumbing, on the other hand, are generally considered to be less likely to be contaminated and therefore are not recommended as sampling sites for total coliform analysis.8. The correct answer is A) .For asbestos analysis, it is recommended to store the collected samples at a temperature of . This temperature range helps to preserve the integrity of the asbestos fibers and prevent any potential degradation or loss of the sample. Storing the samples at higher temperatures, such as , , or , may not provide the same level of preservation and could potentially affect the accuracy of the analysis.
