The City of Kennewick, Washington owns and operates a 12 million gallon per
day (MGD) collector well. Collector well #5 (RC5), is located in close proximity to the
Columbia River and Columbia Pond, one of the river's small tributaries. In 2004, the
Washington Department of Health (WDOH) determined the collector well to be a "groundwater
under the direct influence of surface water" (GWUDISW). This determination was based
primarily upon using the relative risk tables in the U.S. Environmental Protection Agency (USEPA) Microscopic Particulate Analysis
(MPA) Consensus Method (USEPA, 1992). In lieu of constructing engineered filtration to
comply with the Surface Water Treatment Rule the utility opted to apply for alternative filtration
technology (AFT) credit for Riverbank Filtration as provided under the States regulations. In
order to obtain the credit, the Washington Department of Health required the City to perform a
one-year demonstration study. Includes 2 references, table.
