Water System Information
Water System Name: City
O. Box 249, Riggins,
Regularly scheduled meetings:
City council meetings are the second Monday of each at month at
Water Sources and general information: City drinking water is provided by two wells.
To insure that the water you drink is safe it is chlorinated before being sent to the storage tank.
EPA also prescribes regulations which limit the amount of certain contaminants in water provided by public water systems. Some con-
taminants that may be present in source water before we treat it include:
Microbial contaminants such as bacteria, virus and protozoa are very small creatures that may be natural and harmless or harmful if
originating from septic systems livestock operations or wildlife.
Inorganic contaminants such as salts and heavy metals can be naturally occurring or result from urban storm-water runoff, industrial or
domestic wastewater discharges, oil and gas production or mining and farming.
Pesticides and Herbicides may come from a variety of sources such as agriculture, urban storm-water runoff and residential uses.
Organic Chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and
petroleum production, and can also come from gas stations, urban storm-water runoff and septic systems.
Radioactive contaminants, which can be naturally occurring or be the result of oil and gas production and mining activities.
Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants people with HIV/Aids or other immune system disorders, some elderly and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. EPA/Centers for Disease Control and Prevention [CDC] guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (800-426-4791).
Drinking water, including bottled water, may be reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency’s Safe Drinking Water Hotline (800-426-4791).
The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves natural-occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity.
Maximum Contamination Level Goal (MCLG): The level of a contaminant in drinking water below, which there is no known or expected risk to health. MCLGs allow for a margin of safety.
Maximum Contamination Level (MCL): The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.
Treatment Technique: A required process intended to reduce the level of a contaminant in drinking water.
Action Level: The concentration of a contaminant, which, if exceeded, triggers treatment, or other requirements, which a water system must follow.
Each year the city tests drinking water on a monthly basis
for the presence of total coliform bacteria.
Total coliform bacteria are naturally occurring and are used as an
indicator organism for the presence of other harmful bacteria.
The city also tests yearly for the presence of other harmful
contaminants. The results of the
testing done in 2009 are shown in the table below.
More information about contaminants and potential health effects can be
obtained by calling our office at 208-628-3394 or EPA’s Safe Drinking Water
Hotline 1-800-426-4791. Copies of test results can be obtained by calling
Comments: A sample taken April 30 did not arrive at the laboratory until May 4, too late to sample which resulted in a no sample for April.
A sample taken December 9 at City Hall tested positive for total coliform. Follow up samples taken December 16 at four locations had the sample taken at the Emergency services building tested positive, with the other three negative. Both wells were also tested at this time with both samples negative. Follow up samples at city hall and the emergency services building on December 21 were negative. All samples taken were also tested for E-Coli with all samples negative. This was an isolated incident confined to the service line providing water to the two city buildings.
