I typically try to focus our blog topics on content that can help people discern what to do when dealing with radon or water quality issues.  If you, or someone you know, is contemplating buying a home with water quality or radon issues...we can help.

My goal of this post is to give perspective of scale to the the problems some people face when dealing with radon and water quality issues...and hopefully make those of us who feel they have an insurmountable situation - better.

Radon in Air concentrations:  We successfully mitigated a home in Glastonbury, CT (new construction), with an indoor airborne radon concentration of 900 pCi/l

Radon in Water: We successfully mitigated a home in Ridgefield, CT with a waterborne radon concentration that spiked as high as 1.7 million pCi/l.

Arsenic: We installed an absorbtive media treatment system to succesfully remove an arsenic level of 24 ug/l from a private well in Weston.

Bacteria: We've installed numerous Ultra Violet Light sterilization systems for E-coli and coliform bacteria problems throughout CT and Westchester County NY.

Coliform bacteria 

Chlorides: We installed a whole house reverse osmosis system to successfully remove a chloride level of 720 mg/l in a Stamford, CT home.

Hardness: We've installed water softeners to remove hardness concentrations as high as 48 grains per gallon.

Iron in water: We've installed numerous iron filtration systems throughout CT to remove iron concentrations as high as 26 mg/l.

Manganese in well water: We've installed oxidation / filtration systems to remove manganese concentrations as high as 7.5 mg/l

Nitrate: We've installed reverse osmosis systems to remove nitrate levels as high as 16 mg/l

pH: We've adjusted low pH water from as low as 4.6 to neutral (7.0) with a chemical injection system.

Tannins: While not commonly tested; tannins can be difficult to remove from water...we've seen levels as high as 5 mg/l...and successfully lowered them.

Uranium: We have successfully removed uranium concentrations as high as 1,600 ug/l.

The point of referencing the aforementioned high concentration contaminant levels that we've fixed is not for bragging rights.  It's purpose is to illustrate that treatment options exists for any level of contaminant, no matter how severe.

Contaminant levels in both air and water can, and do, fluctuate.  I've seen many homeowners lulled into having a false sense of security because at some point, they performed one test that had favorable results, and never tested again...only to find out at some point that there is a problem. 

Drilling a new well, not buying a dream home, moving to another house, not occupying certain areas of a home, are all alternatives that will avoid having to deal with these situations.  But there's a better option.  We have the ability to solve most any radon or water quality issue to keep you and your family safe and protected in the home that you love.

IRON IN WATER

 iron in water removal

                                                              IRON IN WATER

One of the most common problems private well owners must contend with is iron in water.  Iron is one of the most plentiful elements found in the earth's crust.  Since water wells are drilled into the earth's crust, it makes sense that water wells contain some amount of iron.  Iron in water has a federal maximum contaminant level (mcl) of 0.3 mg/l.  This is a secondary standard which means it is an aesthetically based standard - not health related.  Albeit, medical research has shown that some diseases are linked or exaserbated by long term ingestion of heavy metals such as iron in water

The list of problems encountered when iron is present in water can be daunting. These include; staining of fixtures, shower stalls, appliances, walkways, clothing, even hair & skin!  Iron in water can also foul water heaters, clog plumbing lines, create bad odors and taste and even clog well pumps.  Severe iron contamination can make a home uninhabitable and have a significant impact on the quality of life for the occupants of the affected household .

Iron in water is most commonly found in the ferric or ferrous form.  Ferric iron; also known as "red water iron", is iron that is present in an oxidized or precipitated state.  Ferrous iron...also referred to as "clear water iron", is iron that is "held in solution".  Ferric iron can be filtered out by a basic sediment filter, filter AG, BIRM, or various iron filtration medias.  Ferrous iron can either be removed by a water softener, or by oxidation / filtration (turning ferrous iron into ferric) - and then filter out the precipitated iron.  It may appear that ferric iron is easier to remove...and often it is.  But either species can present unique challenges if conditions are right.  In general; iron removal from water requires; filtration, oxidation / filtration, or ion exchange.

Two less common types of iron found in water are organic (organically bound) iron, and colloidal iron.  These two forms of iron in water can be difficult to remove, with organic iron being the most problematic. However, as many problems that iron in water creates...so too do the solutions exist to solve these problems.

ozonation / filtration                 aeration / precipitation

 

 Depending on other contaminant parameters of the water, ferric iron can be filtered out by either a basic sediment filter, filter AG, BIRM, or various iron filtration medias.  Since water chemistry varies from well to well,there is no 100% fool proof method to address organic and colloidal iron in water.

chlorination / filtration to oxidize and filter out iron  

 Organically bound iron can be difficult to oxidize and may require long "contact times" for an oxidizer (eg; chlorine, ozone, etc.) to break down the organic substance before the iron can be oxidized.  Organic iron is also linked to iron bacteria such as Crenothrix, Leptothrix, and Gallionella.  These microorganisms deposit a gelatinous compound on surfaces it comes in contact with.  A rainbow sheen on the water's surface is indicative to the presence of iron bacteria.

Colloidal iron has the appearance of ferric iron.  It can give the water a pinkish hue.  The tiny specks of collodial iron stay in suspension and are widely dispersed throughout the water.  Removal of this type of iron in water requires a coagulant to form larger particulate which allows it to become more filterable.

Iron in water can require a robust treatment scheme in some cases to assure for long term effective removal.  The worst mistake to be made is short cutting treatment or removal methods.  This will inevitably result in premature system failure or poor performance of the removal system in general.
