Details: SUMMARY: Source coliform sampling invalidation DETAILS: Kathy Casson and Yone called letting us know that the raw water coliform sample taken Thursday, 10/5/06 was invalidated by the lab on Monday, 10/9. The sample was analyzed an hour before it should have been, causing the invalidation. Other recent raw bactis have all been very low, so there is no cause for concern. The rules allow us to waive the 24-hour time limit for resample, so I have allowed a 48-hour resample time, and they will collect a resample on Wednesday, 10/11. This will be an extra sample, as they will also be taking their normal samples daily to get 5 per week. ACTION NEEDED: none - no violation of rules.
