Major Accomplishments Since Last Report






Eklutna WTF Lead Water Production Facility
Ship Creek WTF Placed in Standby Mode
EPA Renewed All Three NPDES Permits
Negotiated Ship Creek and Eklutna
Watershed Risk Assessments with ADEC
Implemented Work Management System
(MAXIMO)
Staffing Reorganization
Eklutna Lead Water Facility
Eklutna more efficient operation
 Produces twice the volume of water
with same size staff
 Duplicated after hours monitoring
equipment at Eklutna
 Allowed reorganization of staffing to
improve effectiveness

Ship Creek WTF in Standby Mode
Ship Creek will be used as backup to
Eklutna and Wells
 Continues to be home base for
Distribution Operations
 Staffed Monday – Friday, 10 hours/day
 Required installation of intrusion alarms
 At minimum, will be operated during
mid-summer

Renewal of NPDES Permits
Increased BOD limits for Asplund WWTF
 Reduced sampling requirements
 Added toxicity testing requirements
 Mark will address in more detail

Source Water Risk Assessments





Worked with ADEC staff to achieve
reasonable results
Finished Girdwood, Ship Creek and Eklutna
Still working on Anchorage and Eagle River
wells
Working with State Parks on Watershed
Protection Agreement
Eric will address in more detail
Maximo Implementation





Entered equipment information for all
facilities into database
Preventive and corrective maintenance work
orders are now generated in Maximo
Time and materials expended in maintenance
activities are recorded in Maximo
Maximo provides improved labor scheduling,
parts ordering and expense documentation
Future enhancements are forthcoming
Staffing Reorganization
Water Section reduced to two groups
from three
 Distribution Operations will operate Ship
Creek when necessary
 Reassigned operators to a pool from
which assignments can be made to
either Eklutna or Distribution Operations
 Reassigned one operator to Girdwood

Reorganization, Continued
Eliminated one Foreman Position
 Eliminated one Superintendent Position
 Renamed Lab Services to Water Quality
Section
 Reassigned Pretreatment Staff to new
Water Quality Section
 Reduced staffing from 63 to 61 funded
positions

2001 Activities
Start up of new solids handling facilities at
Asplund WWTF
 Construction and start up of new disinfection
improvements at Eklutna and Ship Creek
WTFs
 Work with SCADA consultant on design of
new SCADA systems for all facilities
 Continue team building efforts through
involvement in Excellence Adventure

ADEC
Source Water Assessments
Eklutna and Ship Creek and
Production Well Facilities

What is a source water assessment?
A
report created by ADEC Identify source of water and
zone of influence
Analyze what in the area could
affect water quality
Why Complete an Assessment?

Recent amendments to the federal Safe Drinking Water Act
requires ADEC to implement SWP Programs.

The information on sources of contaminants in the protection
areas and the susceptibility of the drinking water supply to
contamination will be used to determine appropriate protection
efforts.

Prevention of contamination is one of the most cost effective
methods of ensuring safe drinking water supplies.

If source water becomes contaminated, expensive treatment or
replacement of the water source may be required before safe
drinking water can be delivered to the public.
How Was the Assessment Done?

ADEC gathered information from public
records and other agencies and created
a draft report

Asked PWS owners to proof data

Create final report and publish it on
their web site
What’s in the report?

Location of source water and areas of
influence

Existing or potential contaminant
sources within the protection area

Assessed “vulnerability” for
contamination
Ship Creek Report Overview
Source – Ship Creek Water Shed
 Sources of Contaminants




Trails, gravel roads, Wastewater holding tanks
and an identified contaminated site
Contaminants – Bacteria and viruses, nitrates
and/or nitrates, volatile organic chemicals, heavy
metals and other organic chemical
Vulnerability Ratings – Medium for bacteria and
viruses, nitrates and/or nitrates, heavy metals,
volatile organic chemicals, other organic
chemicals and synthetic organic chemicals
Eklutna Report Overview
Source – Eklutna Lake Watershed
 Sources of Contaminats – Activities associated
with campgrounds, pit toilets, recreational trails,
gravel roads and an airplane landing strip.
 Contaminants – Bacteria and viruses, nitrates
and/or nitrites, volatile organic chemicals, heavy
metals, and other chemicals.
 Vulnerability Ratings - High for bacteria and
viruses and volatile organic chemicals; Medium
for nitrates and/or nitrites, heavy metals, and
other organic chemicals; and Low for synthetic
organic chemicals.

Production Well Systems
Overview

Reports are in progress


ADEC drafts are completed and AWWU
reviews have been accomplished on Wells
10, 11 and 25 and are reviewing Well 9
Remainder of well systems reports are
expected to be completed over the next
few months
What This Means

These reports give AWWU a foundation for
efforts to reduce high risk areas and
maintain low risk to minimize risk to public
health
Minimize high risk activities - motorboats
 Minimize high risk facilities – open outhouses
 Minimize high risk functions - airports

AWWU and Chugach State
Park Cooperative Agreement

Management and Protection of Chugach
State Park Public Watersheds


“The purpose of this cooperative agreement is to
establish a close working relationship between
Parks/DNR and the staff of AWWU to insure the
continued production of a safe and clean public
water supply.”
