Details: SUMMARY: Assistance with Location of New Well/Reconstruction of Existing well DETAILS: System operates a small system that serves approximately 50 people trough 18 connections. Water from the well is chlorinated then pumped to a 6,000 gallon storage tank. From there water is re-pressurized and distributed throughout the system. System has had positive coliform result from their source water, which triggered source water monitoring per the EPA standards. The samples also tested positive for e coli. The EPA Ground Water Rule (GWR) mandated that corrective actions are taken to either fix the source of the problem, or provide for 4-log treatment of the viruses that would be associated with positive e coli results. System had originally contacted HBH to provide assistance with compliance with GWR. Recommendations were made that detailed how system could comply with the GWR. HBH met with Washington County financing officials, system personnel, DWP staff, and other financing officials in order to develop a strategy for making necessary improvements to the water system well. HBH discussed issues regarding the likelihood of an improperly constructed well and that this well must be repaired or abandoned. I met with system personnel on-site (at well regarding potential improvements and the potential locations for a new well. ACTION NEEDED: Assist system as needed.
