Contact Report Details
|PWS ID:||OR41 00171|
|PWS Name:||CARLTON, CITY OF|
|Who Was Contacted:||Bryan Burnham|
|Contact Phone:||-- (Email address hidden)|
|Contacted By:||ALFAFARA, NICOLE (DWP)|
|Assistance Type:||WATER QUALITY ALERT RESPONSE|
|Reasons:||Lead or Copper
|Details:||DWS Staff reached out to system contact informing them 1) only 19 of the 20 lead and copper samples had been received and a M&R violation would be issued if an additional sample result was not received by 10/10/21, and 2) submitted results indicated the City would likely exceed the lead action level. Exceedances typically involve directing the operator to assess the corrosion control system and collect some water quality parameters but given the system's current situation with purchasing MW&L while the Panther Creek WTP is worked on the system was asked about the intended future use of MW&L (Does the City plan to purchase finished water from MW&L on a regular basis or is this a temporary or one-time situation?).
10/7/2021: System informed DWS Staff they faced participation challenges in LCR monitoring and a few sites collected during recent LCR monitoring were poorly selected (i.e. vacant city building, home being sold, galvanized standing pipe). DWS Staff told system contact that samples dropped at a lab indicate the system determined their collection was accurate. System contact also informed DWS staff that 5 additional samples had been dropped off at the lab and those results are expected to be disseminated on 10/8/2021. Once all the data is received DWS staff will follow-up with the system on next steps.
10/15/2021: DWS staff outlined steps for LCR sample invalidation to the system. This included providing a brief description on how LCR monitoring sites are selected and reviewing all samples collected to ensure site sample selection criteria and sampling protocol were followed.
10/18/2021: System submit a request to invalidate 3 samples.
