Sodium occurs naturally in groundwater, but levels can increase in our drinking water from road salt, water softeners, natural salt deposits, sewage and fertilizers. Safe Home offers a couple kits that provide drinking water testing for sodium in city water and well water supplies.
Parameter Type: Drinking Water Testing for Metals
Parameter Name: Sodium
What it is and Where it Comes From:
Sodium is a chemical element with the symbol Na and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is 23Na. The free metal does not occur in nature and must be prepared from compounds. Sodium is the sixth most abundant element in the Earth’s crust and exists in numerous minerals such as feldspars, sodalite, and rock salt (NaCl). Groundwater typically contains higher concentrations of minerals and salts than surface waters, especially in areas with an abundance of sodium mineral deposits or in areas with sea or estuarine water intrusions. There are several anthropogenic sources of sodium that can contribute significant quantities of sodium to surface water, including road salt, water treatment chemicals, domestic water softeners, and sewage effluents. Drinking water testing gives you several benefits like peace of mind, identifying contaminants in your water, and insight into health concerns. Safe Home offers Laboratory drinking water testing kits for sodium, allowing you to collect your water sample and ship it directly to our EPA-Certified Laboratory. This platform of drinking water testing for sodium will give you an accurate level based on the lowest level of a parameter our instruments can detect (Method Detection Level). Safe Home drinking water testing for metals can be used for city and well water supplies. Drinking water testing should be done any time you notice a significant change in your water quality.
In general, sodium salts are not acutely toxic because of the efficiency with which mature kidneys excrete sodium. However, acute toxicity and death have been reported in cases of very high sodium intake. Acute effects in adults may include dryness of mucous membranes, violent inflammatory reaction, and ulceration in the gastrointestinal tract, along with dehydration and congestion of internal organs, particularly the meninges and brain. Central nervous system disturbances such as convulsions, confusion, and coma may result, and generalized and pulmonary edema are possible. Death may occur from respiratory failure secondary to an acute encephalopathy. Infants and children are somewhat more susceptible than adults to the effects of acute overdoses of sodium chloride because the kidneys of immature individuals are not as effective in controlling sodium levels as the kidneys of adults. The EPA states that people with high blood pressure have an increased risk of developing coronary heart disease, stroke, congestive heart failure, renal insufficiency, and peripheral vascular diseases. However, it must be understood that high blood pressure is a multifactorial disorder, with dietary sodium as one of several factors influencing its incidence. Drinking water testing is a great way to monitor sodium levels in your city or well water supplies.
Solutions to Contaminant Levels:
To remove sodium from water there are a few options reverse osmosis, electro dialysis, distillation, or ion exchange. Reverse osmosis can reduce the silver cation concentration by up to 90 percent of the influent water levels. Reverse osmosis is a process that removes foreign contaminants, solid substances, large molecules, and minerals from water by using pressure to push it through specialized membranes. Here’s how reverse osmosis works. Unlike osmosis, which is a passive process, reverse osmosis requires external force (pressure) to work. Pressure is applied to a highly concentrated solute solution, such as salt water, to pass through a membrane to a lower concentrate solution. The membrane allows water to flow through but blocks out larger molecules, like contaminants. The reverse osmosis process leaves higher concentrations of solute on one side and only the solvent, or freshwater, on the other. Electrodialysis (ED) is used to transport salt ions from one solution through ion-exchange membranes to another solution under the influence of an applied electric potential difference. This is done in a configuration called an electrodialysis cell. The cell consists of a feed (dilute) compartment and a concentrate (brine) compartment formed by an anion exchange membrane and a cation exchange membrane placed between two electrodes. . Distillation can reduce the silver concentration by greater than 98 percent. Distillation is one of the oldest water treatment processes. Water is boiled and the resulting steam is collected and cooled backed to water in a separate chamber. The treated water thus produced is called distilled water that is relatively free of many contaminants. Ion exchange is ions are charged atoms or molecules. When an ionic substance is dissolved in water, its molecules dissociate into cations (positively charged particles) and anions (negatively charged particles). Who do I need to contact to find out more information about water quality in my area? Every community water supplier must provide an annual report to its customers, known as a Consumer Confidence Report (CCR). The report provides information on your local drinking water quality, including the water’s source, contaminants found in the water, and how consumers can get involved in protecting drinking water. How often does the local public water system preform drinking water testing? Frequency of drinking water testing depends on the number of people served, the type of water source, and types of contaminants. Certain contaminants are tested more frequently than others, as established by the Safe Drinking Water Act. You can find out about levels of regulated contaminants in your treated water for the previous calendar year in your annual Consumer Confidence Report (CCR).
