| Details: | SUMMARY: Contact Time Testing DETAILS: The system owns and operates a water system, which supplies approximately 600 people through 362 connections. The source water for the system comes from 2 springs. HBH was contacted by Mr Felley following a positive e coli test on the smaller of the two springs (Pirate Springs). A site visit was completed as was a memorandum regarding the site visit observations. I corresponded with system staff regarding the possibility of completing a tracer test on Pirate Springs while isolating the reservoir from hydraulic influence of the other springs/reservoirs. I reviewed historic flow and reservoir height data to determine if peak flow from the reservoir can be determined. ACTION NEEDED: Compose CT study methodology and complete tracer testing. | ||
