Proposed Project
Factors Impacting Effective Removal of Arsenic by Household Water
Purification Systems--New--National Center for Environmental Health
(NCEH), Centers for Disease Control and Prevention (CDC).
Background and Brief Description
Epidemiologic evidence strongly links ingestion of water containing
inorganic arsenic with an increase in bladder cancer and other cancers.
In Maine, approximately 10% of private domestic wells have arsenic
concentrations greater than Maine's health standard for water of 10
[mu]g/L. In wells with high arsenic concentrations, ingestion of water
can be the dominant source of arsenic exposure. The preferred method
for treating domestic well water containing elevated levels of arsenic
is point-of-use water-treatment devices.
The purpose of the proposed study is to evaluate how the efficacy
of water-treatment devices is affected by user behaviors such as
maintenance and selection of appropriate technologies and by variations
in water chemistry. The requested three year clearance for this study
will focus on a total of 100 households. Approximately 200 households
will be recruited and screened to ascertain the 100 eligible
households. Recruitment is limited to areas of Maine that have high
concentrations of arsenic in groundwater.
The results will demonstrate how arsenic removal systems are
working in the real world. The data will give insight into how
homeowners are collecting, interpreting and utilizing information on
water treatment in order to select an arsenic-removal system. The data
will show how well the chosen systems are removing arsenic, and how
well they are being maintained. The results will thus identify risk
factors that contribute to a failing treatment system.
The study will have a cross-sectional component and a temporal
component. For the cross-sectional component, total arsenic, inorganic
arsenic species, and selected geochemical constituents will be
quantified by the influent and effluent (flowing in and flowing out) of
filtration devices treating these 100 domestic well-water supplies. The
study team will administer questionnaires to each participating
household to collect data on the type of treatment unit used, routine
operation parameters, and suggested and actual maintenance schedules.
For the temporal component of the study, the study team will test the
influent and effluent of the treatment units of 30 participating
households for total arsenic one time per year. The percentage of
arsenic removed by the filter will be compared to the study criterion
selected to indicate that a filter is failing. If the arsenic removal
level indicates that a treatment unit meets the criterion for failure,
treatment unit influent and effluent water will be analyzed for
inorganic arsenic species and geochemical constituents to determine
whether the chemistry of the water has changed sufficiently to explain
the failure.
A follow-up questionnaire will be administered biannually and at
the time of a system failure to determine when the unit was last
maintained and if operation and maintenance have changed. CDC/NCEH will
request a 3-year clearance. There is no cost to participants other than
their time. The total annual burden hours are 56.
