In an effort to enhance public awareness
about the water supplied to our customers, the Board of Commissioners wish to provide the
following water quality information. Beyond providing general information about the
regulatory aspects of the industry, we hope this information answers questions you may
have about the quality of your drinking water.

Lakehaven Utility District provides water and sewer service to Federal Way
and surrounding communities.
The Washington State Department of Health
(DOH) requires that each public groundwater source be sampled for a range of inorganic
chemicals at least once every three years. Additionally, bacteriological tests must be
performed on no less than a monthly basis. To comply with these requirements, groundwater
from our 21 production wells is sampled and tested both annually for inorganic chemicals
and monthly for bacteriological conditions.
first page lists values for PRIMARY
Inorganic Chemicals and the average concentration levels of these chemicals
found in our groundwater. Maximum Contaminant Levels (MCL's) for PRIMARY
inorganic chemicals have been developed by the Environmental Protection
Agency (EPA) based upon their capacity to impact human health. All of the
groundwater sources in our water district comply with these PRIMARY
second page lists values for SECONDARY
Inorganic Chemicals and the corresponding average concentration found in our
drinking water. SECONDARY inorganic chemicals can affect the taste, odor,
and clarity of drinking water, but do not pose a threat to human health.
Some groundwater sources exceed the Secondary MCL for iron and manganese
(commonly found in groundwater within this region). With the concurrence of
DOH, this problem is managed with an aggressive main cleaning and flushing
program which removes deposited iron and manganese scale from water supply

groundwater pumped from local wells and surface water from the Green River
Second Supply Project (SSP).
Second Supply Project Water
In the early to late 1990ís, the
District utilized water from the City of Tacoma to supplement its supply
needs, so the water quality is known to many of our water customers.
However, for those customers that did not receive this water in the past,
the differences from Lakehaven Utility Districtís well water are generally
A difference in taste may be
noticeable since the water is drawn from a surface water supply, the Green
River, rather than from groundwater wells.
The water can be warmer in the
summer and slightly cooler in the winter.
The water will typically have a
higher chlorine content compared to the Districtís well water.
will contain fluoride per the City of Tacomaís standard practices.
water may have some color (greenish/yellow tint) from time to time.
water may have a slightly musty smell to it seasonally.
All water will be tested to
ensure it meets all the federal and state drinking water standards before it
will be delivered to the District customers. The testing will be done by
both the City of Tacoma Water Quality staff and the District Water Quality
staff. If you have any water quality questions please contact Stan French,
