LLC for Iron and Manganese Evaluation and Control Study AGENDA BILL CITY OFBREMERTON CITY COUNCIL 5D Study Session Date: COUNCIL MEETING Date: Department: Presenter: February 20 2020 Maroh4 2020 Public Works & Utilities— Apfelbeck 5 SUMMARY: The City ofBremerton water utility has experienced periodic customer complaints and operational challenges related to discolored water from the accumulation of iron and manganese in the system. Though these metals are naturally -occurring and primarily a nuisance, causing staining and unpleasant odors and taste, excessive levels of these metals may be harmful. Further, regulated contaminants such as arsenic and lead, which are particularly harmful to human health, may attach toiron and manganese solids and naauop8ndinthe water during high flow conditions. The objective of this study is to quantify the occurrence of iron and manganese from source (surface and groundwater), through treatment and storage, and throughout the distribution system during both normal operations and high flow events such as avatenn flushing. This work will review existing data, develop and implement monitoring plan tofill data gape, and use resulting monitoring data to develop a set of recommended treatment and/or operational measures to minimize iron and manganese accumulation.

In 2012, the City contracted with Confluence Engineering Group (Confluence) to perform a desk -tap review of distribution system issues, specifically related to iron and manganese attributed to the Anderson Creek wellfield. Confluence completed a Technical Memorandum (TM) reporting observations based on available data, implications of identified monitoring and operational data, and recommended additional monitoring steps. The TM also outlined potential control strategies. This work will update and expand previous recommendations based on additional data, if available, identify information gaps, and provide guidance and assistance for additional field data collection. Collected data and information will be used to develop a set of recommended treatment and operational measures that will be collaboratively screened with the City for future implementation. This Scope of Work (Scope) presents Confluence's approach for the Iron and Manganese Evaluation and Control Study. SCOPE OF WORK —IRON AND MANGANESE EVALUATION AND CONTROL STUDY Task 1—Kick-off Workshop &Site Visit Objective The purpose of this task is for Confluence to meet with the Bremerton personnel responsible for water quality assurance and field operations to provide an overview ofthe study's objectives, anticipated impact to City personnel, to support cross -organizational awareness, and to solicit operational knowledge important to the successful completion of the project.

We will only issue the most current edition of the ACORD certificates of insurance - a revised edition of the Acord 25 was published in October 2009. The issuance or modifica#ion of a certificate of insurance that in any way misrepresents any material term, condition, coverage or other provision as set forth in the policy, or deliberately or falsely amends or alters the insurance policy or assists in such issuance or modification violated the state law and subjects the violator to civil and criminal penalties. The only information allowed to be entered in the Description of Operations area of the ACORD certificates of insurance is the description of operations, the locations and/or vehicles covered by the in -force policy. Wording referencing forms or status must be added in the Remarks section. The certificate holder is not owed a duty to be notified in the event the insurance policy is cancelled. There is no longer a "30 day notice" provision in the certificate and it cannot be added. Only a policy can obligate an insurer to provide notice of cancellation. Unless a policy's provisions explicitly provide for notice to a party also listed as the certificate holder on the certificate of insurance, the insurer is not obliged to notify that party. Please note a certificate of insurance is simply a summary of the designated insurance policy and does not /cannot modify or amend the reference insurance policy or confer any right upon the certificate holder. For purposes of this notice, "certificate" or "certificate of insurance" means any ACORD certificate of insurance, which is prepared or issued by an insurer or insurance agent as evidence of property or casualty insurance coverage but does not include an actual copy of the insurance policy or insurance binder. Please contact the Washington State Office of the Insurance Commissioner for further explanation. THIS ENDORSEMENT CHANGES THE POLICY. PLEASE READ IT CAREFULLY.
