Iron and Manganese
Typical of much of the Island's water, our water contains elevated levels of Iron and Manganese, which are abundant in the rocks and soils in the area. These are secondary contaminants and the US EPA has not mandated treatment to reduce the levels of contamination. Scientific findings suggest that the levels found pose no threat to human health. Manganese and iron are considered to be an aesthetic problem. At sufficient concentrations, iron can adversely affect the taste of water and can leave rust colored stains on laundry, plumbing fixtures and porcelain. Manganese can cause similar problems, has a bitter metallic taste and may leave black "specks" in ice cubes.
As in previous years, we have again had many problems associated with the snow, freezing weather, heavy rains and flooding - all of which can cause water pipes to break and necessitate the need to get the water turned off in an emergency. It is the responsibility of your water system (the purveyor) to deliver safe drinking water to your property. As a rule, this responsibility stops at the meter or shut off valve - usually located at, or close to, the property line. However, it is the responsibility of the home owner to know where their shut off valve is located and keep the area clear and readily accessible.
This year, King Water has had more calls than ever from home owners who have leaks on their property or in their homes and who cannot find a shut off valve, or find it only to discover that it does not work. Please take time to locate your shut off valves and keep them clear and in working order; this way, if there is a leak in your home it will be a quick and simple process to switch off the water and minimize any damage to your property.
To ensure that tap water meets acceptable drinking standards, the US EPA prescribes regulations limiting the amount of certain contaminants that may be in drinking water. As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and radioactive material, and can pick up substances resulting from the presence of animals or from human activity. Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some of these contaminants. However, their presence does not necessarily mean that the water poses a health risk. Such substances may include:
Microbial contaminants, such as bacteria and viruses, which may come from sewage treatment plants, septic systems agricultural livestock or wildlife. These are tested for monthly.
Inorganic contaminants, such as salts and metals, which can be naturally occurring or may result from urban storm water runoff, industrial or domestic wastewater discharges, mining or farming. These are tested for based on a schedule prescribed by the state Department of Health (DOH); they include nitrates, which are tested for annually.
Pesticides and Herbicides, which may come from a variety of sources such as agriculture, storm water runoff and residential uses. These are tested for based on a schedule prescribed by the DOH.
Organic Chemical Contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes, gas stations, storm water runoff and septic systems. These are tested for based on a schedule prescribed by the DOH.
Radioactive contaminants, which are usually naturally occurring. These are tested for based on a schedule prescribed by the DOH.
Some people may be more vulnerable to contaminants in drinking water than the general population. They include immuno-compromised persons such as persons with cancer, those undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, the elderly and infants, who can be particularly at risk from infections. These people should seek advice from their health care providers before drinking any water. More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency Safe Drinking Water Hotline (800- 426-4791).
The State legislature has directed the Department of Health (DOH) to adopt an enforceable Water Use Efficiency (WUE) program, which became effective January 22, 2007. In June 2008, a King County Superior Court judge ruled that privately owned water do not have to comply with the WUE; as previously reported, the ruling is being appealed by the Department of Health's (DOH) Office of Drinking Water - there have been no developments in 2009.
The DOH is recommending that privately owned water systems voluntarily comply with the efficiency rule. Given the background, it is likely that some requirement will prevail to at least install meters and monitor for leaks. Accordingly, it is recommended that systems continue to plan for meter installation and, when installed, reconcile water pumped with water used to identify significant leaks.
