Pursuant to the
MASTER AGREEMENT FOR PROFESSIONAL SERVICES
BETWEEN
CITY OF MERIDIAN (OWNER) AND MOUNTAIN WATERWORKS, INC. (ENGINEER)
This Task Order is made this 11th day of September 2018 and entered into by and
between the City of Meridlan, a municipal corporation organized under the laws of the
State of ldaho, hereinafter referred to as "City", and accepted by Mountain Waterwo rks.
lnc.. hereinafter referred to as "Engineer" pursuant to the mutual promises, covenant and
conditions contained in the Master Agreement (category 1D) between the above
mentioned parties dated October 1,2017 . The Project Name for this Task Order 10968
is as follows:
OPTIMAL CORROSION CONTROL TREATMENT REPORT
PROJECT UNDERSTANDING
The City of Meridian's (City) public water system (PWS) is required to sample and report
instances of lead concentrations found in residential homes that exceed regulated limits.
Previous sampling events indicate that multiple water samples collected from the PWS
contain elevated levels of lead above the 90th percentile action level of 0.015 milligrams
per liter (mg/L) prescribed in the federal Lead and Copper Rule (LCR,40 CFR 141 .80).
The elevated lead levels are believed a result of potentially aggressive water chemistry
interacting with lead-containing pipes, fixtures, and fittings within the water distribution
system and end user point of delivery.
The purpose of this project is to understand the effects of our raw and treated water
chemistry with the known types of water lines and appurtenances within the City's
distribution system and investigate and identify feasible treatment options, if determined
required, to mitigate the PWS customers' potential exposure to lead in drinking water and
to ensure the PWS achieves compliance with EPA lead standards.
compliance with EPA lead standards.
The project approach will include the following actions:
( 1) Conduct a comprehensive pilot test to determlne the efficacy of treatment
methods in reducing and controlling lead within raw and treated drinking water.

(2) Prepare an Optimal Corrosion Conlrol Treatment (OCCT) Evaluation Report
detailing the findings of the pilot test as well as a comparative analysis of similar
public water syslems currently utilizing lead treatment technologies.
(3) Stakeholder meetings including the City, ldaho Department of Environmenlal
Quality, and Mountain Waterworks' personnel, will be conducted to determine the
requirements, objectives, and deliverables of the Report.
(4) Prepare a Water Master Plan Addendum if the study results show it is necessary.
Major Tasks
Mountain Watenrvorks, lnc. will perform the following tasks for the Optimal Corrosion
Control Treatment Evalualion Report:
Task I - Project Management and Administration
Task2-PilotTest
Task 3 - Report (or Water Master Plan Addendum if necessary)
Task 4 - Agency Coordination, Meetings, Public Outreach
Task 1: Project Management and Administration
lvlountain WateMorks will provide the overall project planning, management, scheduling,
coordination of efforts, and the day-to-day administrative tasks required for this Task
Order.
Progress Reports
The project is assumed to require nine to twelve months for the investigation work, pilot
test, and OCCT Report preparation. Mountain Waterworks will prepare written monthly
progress reports. The reports will include the tollowing items:
o A written description of the progress ofthe work accomplished to date.o A summary of project issues and concerns that need to be resolved.r A summary of changes in contract amount or time (if applicabte).o Itemized monthly invoices for work completed.
D eliverables lor this Task
o Monthly progress reports and itemized invoices
TASK 2: Pilot Test
lVlountain waterworks will perform a pilot test at an existing city well before and aftertreatment to determine the best treatment alternative for reducing and controlling lead

within the drinking water. The test location will be selected based on a review of existing
well water chemistry collected from the distribution system.
The pilot test will include up to five potential treatment alternatives with an additional test
run as a control. A combination of lead coupons and aged galvanized pipe loops may be
used to determine the mosl effective treatment method. The pilot test will be conducted
over a six-month period with the potential to extend up to an additional three months if
treatment objectives are not satisfactorily met.
The engineer will prepare a pilot test plan, design schematic, equipment list, and control
description for the pilot test and provide to the city. The city will purchase the components
and install with the direct guidance of the engineer.
The engineer will work closely with city personnel to operate the pilot test and conduct
weekly field visits to ensure the pilot equipmenl rs operating properly. The lead coupons
will be weighed at predetermined intervals to monitor the corrosive effects of the water
and the effects of the various treatment alternatives. Water samples will also be collected
to determine the leaching potential of the galvanized pipes used in the pipe loop
configurations.
Deliverables for this Task
o Pilot test plan with installation requirementso Pilot test data summary of treatment alternatives
Task 3: Optimal Corrosion Control Treatment Evaluation Report
Mountain Waterworks will prepare the OCCT Report in accordance with EpA, ldaho
Department of Environmental Quality (IDEQ), and 40 CFR 141 .82. Data produced from
the pilot testing will be analyzed to determine the efficacy and efficiency of the tested
treatment allernatives and varying loading rates. The analysis will also estimate required
chemical dose of each. The report will include an evaluation of the tested treaiment
alternatives and include a comparison and recommendation including estimated costs for
selecting, installing, and the ongoing operation requirements of the top three best
available technologies.
The engineer will meet with the city and IDEQ representatives to develop the key
components of the occr to ensure compliance with the requirements with lDEe and
EPA Lead and copper Rule standards. The occr Report will be developed and provided
to lhe city with the intent to be retained by the city in the event the document would be
required for agency review and approval.
Six (6) hard and two (2) electronic (1- editable, 1 - non editable) copy of the occr wilt
be submitted to the city for initial review. Following the city's review, the report will be
updaled and provided to the City.
Deliverables for this Task
o Draft OCCT for City Reviewo Final OCCT for City Approvat
