Hardness is often referred to as the ability of your well water to react with soaps. Manganese is a naturally occurring mineral that is present in soils, rocks, and sediment. Hibbert, D, Mineral Levels of 20 Municipal Water Supplies, 2002, Personal Communication. After exposure to air, they become oxidized, leaving a solid reddish-brown stain on laundry, plumbing fixtures, porcelain, etc. Note that a new or deeper well may not yield a satisfactory water source. google_ad_type = "text"; The water softening process allows soap to form suds. To get any real idea … Check the yellow pages under "Water Purify & Filter Equipment" or "Water Treatment Equipment, Service, & Supplies" to bring in a water specialist to help get the situation under control. Check the filter on your water clarifying system to see if it needs changing, but my guess is the Kenmore unit is not the best system for your situation. An alternate water supply would be to hook up to community water, if it's available, or drill a new well in a different area or a deeper one into a different aquifer. promoting knowledge of nutritional magnesium, Consumer Education Research on Magnesium Issues, Magnesium Research Reports from 2015 Keiser University class, Publications from the Center for Magnesium Education & Research, The Mg Hypothesis of Cardiovascular Disease: A Bibliography, http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&dopt=Citation&list_uids=11318912. Calculation: Multiply the calcium concentration in ppm by 2.5. , personal communication. There is also some evidence that calcium and magnesium in drinking water may help protect against gastric, colon, rectal cancer, and pancreatic cancer, and that magnesium may help protect against esophageal and ovarian cancer. Manganese, acting in the same manner, causes brownish-black stains. Yet manganese can also present a problem if found in well water in quantities greater than 0.05 mg/L. This lends credibility to both sets of numbers. addy34530 = addy34530 + 'IX' + '.' + 'netcome' + '.' + 'com'; How can you tell? Beyond this, there’s a story for each of these numbers. google_color_bg = "FFFFFF"; As mentioned separately as well as jointly, The National Primary Drinking Water Regulations (NPDWRs) is legally enforceable primary standards and treatment techniques that are applicable for public water systems. The maximum level of iron recommended in water is 0.3 mg/L. //--> Some areas have a higher concentration of magnesium and iron in well water. Calcium and magnesium bind with soap so that it will not make suds, but instead produce a scum that can stay on clothes and dishes, etc., leaving them grungy. Some areas have a higher concentration of magnesium and iron in well water. It is essential to human nutrition, but in water it is generally regarded as unhealthy for humans in concentrations of as little as 0.5 parts per million. In coal mining regions of the state, these metals may also occur from both deep and surface mining activities. Your city or town undoubtedly has its own story. You need JavaScript enabled to view it. Subtract this number from “hardness.” Divide the result by 4.1. The maximum level of iron recommended in water is 0.3 mg/L. A laboratory test of the water will yield the extent of the iron and manganese contamination. Another source is The Pocket Guide to Bottled Water by Arthur von Wiesenberger, 1991, also available via Amazon.com. Question answered by Leon A. Frechette. google_color_text = "000000"; Natural sources of iron and manganese are more common in deeper wells where the water has been in contact with rock for a longer time. A water treatment contractor can assist in getting the water tested to determine whether you have iron and/or manganese in the water and the concentration of these elements. In that case, manganese can give the water an unsightly brown appearance, while also often lending the water an unappealingly bitter taste. They contribute to the hardness . If you have a value for calcium and hardness, you can use a calculation to determine the magnesium, which sometimes works, but not always. Geologic Survey Water-Supply paper #1812. For the most part, the recent values Dennis compiled fall into the same order, generally, as values from a large survey of USA cities’ water conducted in 1962 and published in the Geologic Survey Water-Supply paper #1812. These values are imprecise and of variable accuracy. Magnesium iron in well water stains everything a brown to red color, even with a Kenmore water clarifying filter system. var addy34530 = 'Magnesium' + '@'; We have had a geologist, Dennis Hibbert, compile recent values for magnesium and calcium from 20 U.S. cities, and they are listed below. These values, ppm, are parts per million or milligrams per liter of water. google_ad_channel = "8044902136+3282025293"; google_ad_client = "pub-8907726949391961"; They may have only hardness, which is a combination of both the calcium and magnesium. the contribution of drinking water to calcium and magnesium intake; health significance of calcium and magnesium; role of drinking-water in relation to bone metabolism; epidemiological studies and the association of cardiovascular disease risks with water hardness and magnesium in particular; water production, technical issues and economics. The nutritional essentiality and benefits from sufficient dietary intakes of calcium and magnesium are well established but quantitatively imprecise.
