| Contacted By: | KELLEY, KAREN (REGION 2) | ||
| Contact Method/Location: | Office | ||
| Assistance Type: | WATER QUALITY ALERT RESPONSE | ||
| Reasons: | Coliform Chlorine |
||
| Details: | SUMMARY: Positive total coliform routine sample collected 3/28/2007 DETAILS: The special/raw sample I collected while on site 3/28/2007 for a plan review inspection of the new chlorinator was positive for total coliform (absent for e. coli). The routine sample I collected at site #480 was also positive for total coliform (absent for e. coli). The routine sample was likely positive because the chlorine dosing tank was empty and there was no chlorine in the distribution system at the time of sample collection (see contact report for 3/28/2007). I contacted a resident who was filling in for the managers today to discuss the situation. The resident agreed to collect the required 4 repeats samples for the managers today and will contact me with the results. We also discussed the need to assure free chlorine residuals are maintained at a minimum of 0.2 mg/L measured daily. Given the positive result at the source, the system is required to install contact time as stated in Tom Charbonneaus 2/23/2007 plan approval letter. I contacted the owner, Delmar Salazares today and informed him of the situation. Delmar asked that Tom C. send the contact time requirements and options for compliance for this system to him in writing and copy Doug and Pat Chipman, Managers. ACTION NEEDED: Follow-up with Tom Charbonneau concerning plan review for the necessary contact time. Await results of repeat samples and follow-up with the managers and/or owner. | ||
