Testing Your Water For Lead (External Partner NTL)


Is there lead in my drinking water?   Lead (DIY) can be harmful to your health, but just how harmful depends on how much lead gets into your body, your health, and where the lead becomes stored in your body.  This website provides information about lead in drinking water. If you are looking to get lead, metal, and corrosive water testing done on your drinking water - send your information to the Water Guy (Mr. Brian Oram, PG) (please include the source of your water and any specific concerns). 

Like nitrate, it is difficult to understand why lead in drinking water is a potential health hazard or even a concern. Most people believe that there water comes from pure sources without any contamination or that the water has been treated, so there is not a problem. This is not the cause for lead. The primary source for lead in most drinking water sources is the piping used within a distribution system or the household pluming. Other routes of lead exposure include: lead paint used in homes prior to 1978, dust or soil containing lead, food grown in contaminated soil or stored in poorly glazed pottery, and more.
 

Lead The Concern (Lead in Drinking Water):

Lead is a toxic metal that is harmful to human health; there is NO safe level for lead exposure. The degree of exposure depends on the concentration of lead,  route of exposure  (air, water, food), current medical condition, and age. It has been estimated that up to 20 % of the total lead exposure in children can be attributed to a waterborne route, i.e., consuming contaminated water.  In addition, infants, fetuses, and young children are particularly vulnerable to lead poisoning. This is because they usually consume more water and their bodies are actively developing, which facilitates the bioaccumulation of lead.

High levels of lead contamination in a child can result in convulsions, major neurological damage, organ failure, coma, and ultimately death. Moderate to low levels of exposure may result in hearing loss, inhibit growth, and cause learning disabilities. There may be no signs of lead poisoning or the signs could mimic a flu or other gastrointestinal disease. The symptoms may include: cramps, irritability, fatigue, vomiting, constipation, sleep disorder, poor appetite, and trouble sleeping. Unlike other contaminants, lead will accumulate within the body over time, i.e., bioaccumulate.  Lead will tend to be stored in the brain, bones, kidneys and other major organs. It can be stored in child’s blood for months and bones for many decades. Some of the effects of lead poisoning can not be cured, but it is possible to reduce exposure to lead.
 

The Lead Source- One Source Drinking Water:

Drinking water is only one of the possible routes of exposure to lead contamination, but it is one of the easiest routes of contamination to reduce. The primary route for lead poisoning in drinking water is not old contamination of the water by leaded fuels, old batteries or some hazardous waste site, the primary route is the distribution system used to carry water to your home and more importantly the plumbing within your home. That is right: YOUR household plumbing may be the cause for lead in your drinking water. In older homes,  lead was used  to make the piping and/or solder.  In homes, built prior to 1930’s water pipes were primarily made from lead. These pipes can be identified because the piping tends to have a dull gray color, can be scratched with a key, and a magnet will not stick to the piping. In buildings built between the 1930’s and early 1980’s, copper pipes were often used, but the solder contained elevated levels of lead. In the 1950's and 1960's galvanized water lines was utilized in new home construction.  Currently, this type of piping is not widely used, but it is more commonly used with well water applications.  This piping is steel piping that has a zinc coating to reduce the tendency for the piping to corrode.  When this pipe corrodes, the pipe rust from the inside of the pipe and then works outward.  When this occurs, the water may produce intermittent discolored water that tends to be brown, yellow, or reddish brown, and the piping will likely clog with rust and most likely collaspe over time. This does not mean that a newer home is safe from lead contamination; in fact, the available data suggests that buildings less than 5 years old can have high levels of lead.  In fact, buildings built prior to 1986 likely contain some lead plumbing.  Prior to 2014, the legal definition for "lead free" was plumbing fixtures with a lead content of less than 8 %.  In 2014, the term was redefined to include only fixtures with a lead content of 0.25% and newly installed fixtures must use the "lead free" materials, but this did not apply to fixtures currently in use.  
 

Water Quality as it relates to Lead (Lead in Drinking Water):

The water quality of your drinking water can have a great impact on the lead level of your water.  If your water is soft or corrosive, this type of water can accelerate the leaching of lead and copper and other metals from your household plumbing and water fixtures. The signs of this type of problem would include: greenish rings (copper) around basins, metallic or bitter taste to your water especially in the mornings, and frequent leaks/ evidence of corrosion of you household plumbing.
 

Lead Testing:

If you suspect that your water contains lead, it needs to be analyzed by a certified laboratory, not someone giving a free analysis to sell you some type of treatment systems or at a minimum get a Do-It-Yourself Screening Test. You can usually receive a free listing of commercial laboratories from your local county health department or state department of environmental protection. Have you water evaluated for lead, the certified laboratory should request a first draw, after flushing take a second sample and provide you with sampling instructions and containers. At this time, I would also recommend that you have the samples tested (City Water  / Well Water) for copper and at least one of the samples tested for pH, alkalinity, calcium hardness, chloride, sulfate, and total dissolved solids, plus have the laboratory calculate a corrosivity index.  If the water has an odor or there are slime coatings, you may need to test the bacterial quality of the water and have a slime bacteria test conducted.  It is possible, the water is chemically and biologically corrosive and maybe you have MIC (Microbiologically Induced Corrosion) problem.
 

Action - I think I have a Problem:

* Contact family physician and see your doctor- Please do not panic, you may not have a problem.
* Have the members of the household’s blood checked for lead.
* Have your drinking water analyzed by a certified, approved, or reputable laboratory. 

 

In the interim, you may be able to flush the water lines to reduce the level of lead in the water. Overnight, the water reacts with the piping and leaches lead and other metals out of the piping or solder. Depending on the amount of lead solder in your home, it may be possible to install a neutralizer. An acid neutralizer would react with the corrosive elements of your water rather than permitting the water to react with the piping. In more extreme cases, it may be necessary to replace some or all of the plumbing with copper lines using a low/no lead solder.
 

Important Tips:

Hot water usually contains more lead than cold water. Therefore, use cold water when making baby formula and cooking.   When considering a point-of-use treatment system, please keep in mind that most systems are certified assuming the water has been treated to or very near potable water quality standards.  A carbon or particulate filter does not remove all the lead from the drinking water, but some carbon block systems have been certified for lead reduction, see NSF.  A water softener may reduce the level of lead, but if a the water is overly softened it may become corrosive and leach lead from the piping and solder.  
 

Primary treatment options for lead:

1) Corrosion control and piping upgrades
2) Automatic Resin Based System with special medium for lead reduction - home water treatment solutions.
3) Reverse Osmosis- Point of Use Only (small volumes)
4) Distillation Unit or Counter Top Cooler Units- Point of Use Only (small volumes)
5) Carbon Block/ Speciality Filtration
6) Whole House Multiple Barrier Filtration
