Water Quality
The Kennewick Irrigation District (KID) has determined that expansion of water facilities and solutions to environmental and conservation issues are necessary to continue supply of irrigation to its ratepayers. The Board of Directors of the KID has determined to expand water resources and power generation. This shall include surface and aquifer sources of water, sewerage facilities, potable water treatment and distribution and power generation.
AVOID CROSS-CONNECTIONS
A cross-connection occurs when a potable water supply (drinking water) is connected to an untreated water supply (irrigation water) without adequate backflow prevention. The connection is dangerous because the irrigation water may contain harmful pesticides and bacteria, which could cause health problems. The KID does not promote the use of cross-connection devices. Please contact the Washington State Department of Health for more information on their use and regulation.
FOR POTABLE DRINKING WATER
The EPA sets standards for our drinking water quality. These standards are regulations that EPA sets to control the level of acceptable contaminants in the nation’s drinking water. These standards include assessing and protecting drinking water sources; protecting wells and collection systems; making sure qualified operators treat water, ensuring the integrity of the water distribution systems; and making information available to the public on the quality of our drinking water. We treat our water according to both Washington State’s and U.S. EPA’s regulations.
Both tap and bottled water originate as “surface water” from rivers and lakes or as “ground water” from springs and wells. As water travels over the surface of land, or through the ground, it dissolves naturally occurring minerals and, in some cases, radioactive materials. Water picks up wastes both from human and animal activities. Surface water is filtered and disinfected to remove bacteria, viruses and protozoa. Ground water is usually filtered naturally.
KID’s water is some of the best in the nation. During recent years, we have sampled many different chemicals and have found very little contamination. Contamination is anything other than pure water. We sample total coliform bacteria as an indicator of microorganisms that should not be present. Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate a health risk. More information about contaminants and potential health effects can be obtained by calling the KID or U.S. Environmental Protection Agency’s Safe Drinking Water Hotline at (1-800-426-4791).
CANAL TREATMENT
The Kennewick Irrigation District is providing public notice that it will be applying aquatic herbicides to its irrigation canals in accordance with the Washington State Department of Ecology Permit No. WAG-991000.
The purpose of aquatic herbicide applications is to control aquatic weeds and algae within the irrigation delivery system.
Treatments will be to all irrigation canals constructed by the United States Bureau of Reclamation within the boundaries of the Kennewick Irrigation District located in Benton County. The herbicide products to be used are Nautique (copper carbonate), Captain (copper carbonate), Copper Sulfate Crystals (copper sulfate pentahydrate), Green Clean Pro (sodium carbonate peroxyhydrate), and Cascade (dipotassium salt of endothall).
Treatments will be from May 1, 2011 through October 1, 2011. All canals will be treated on an as needed basis with treatment sites posted in accordance with Permit WAG-991000. Waters within the delivery system of the Kennewick Irrigation District are intended for agriculture purposes only—not for recreation, aquaculture, human and animal consumption or use.
Chemicals will be applied under the direction of: Ed Everaert, KID Operations Manager (509) 586-9111
