Where does lead come from?
The lead may originate from water supply contamination, from corroding submersible pump parts, or from corroding lines in a public water system. In the U.S., the problem is seen in homes built before 1986. Even so-called “lead-free” plumbing may contain up to 8 percent lead.
Why is well water tested?
Testing is critical for individuals who live in homes not connected to a public water supply. Well water must be tested regularly to ensure it is safe to drink.
Does hot water dissolve lead?
Hot water dissolves lead. The process of heating the water can concentrate the lead somewhat when it reaches the boiling point. Flushing the water system may be a better stop-gap measure, experts say.
Can lead be replaced in a water system?
This is often plastic piping, such as PVC. If, however, lead service lines within a public water system are the source of the problem, replacement will not be effective. If using a private well, the Centers for Disease Control recommends looking at both the well and pump as potential lead sources.

Why does lead in water increase when boiling?
Because some of the water evaporates during the boiling process, the lead concentration of the water can actually increase slightly as the water is boiled. If it is not possible or cost-effective to remove the lead source, flushing the water system before using the water for drinking or cooking may be an option.
What causes high lead levels in water?
Lead pipes are the main contributor to high lead levels in tap water. Other sources include parts of the water delivery system such as lead solder used to join copper pipes, brass in faucets, coolers, and valves.
Where is lead found?
Lead is a naturally occurring bluish-gray metal found in small amounts on the earth’s outer layer. Lead can be found in all parts of our environment. Much of it comes from human activities including burning fossil fuels, mining, and manufacturing. Lead is found in many different materials.
Can brass be used to seal a well?
Although brass usually contains low lead levels, the lead can still dissolve into the water, especially when the fixtures are new. Private wells more than 20 years old may contain lead in the “packer” element that is used to help seal the well above the well screen.
How long does it take for lead to drop in water?
Other research has shown that when some utilities start dosing with orthophosphate to cut lead levels, dissolved lead levels drop almost immediately—while it can take six months or more for particulate lead levels to decline. Yet other studies suggest that higher doses of phosphate can actually increase water contamination with particulate lead.
How do microbes affect lead levels in drinking water?
How microbes affect lead levels in drinking water is an emerging area of research. A lead pipe seems like an inhospitable place for a microbe. But many bacterial species, particularly those found in metal-contaminated soils, tolerate metals, Gagnon says. While some scientists question the role that microbes play in lead release, new research suggests they could be important. For example, some microbes secrete acids that can affect metal corrosion.
Why is orthophosphate added to water?
Other water systems are under pressure to add orthophosphate to control lead, to make an extradurable lead-phosphate scale. Water utilities are reluctant to do this, in part because excess phosphate can affect wastewater treatment and drive algal blooms downstream of sewage plants.
What is the standard solution for Green Bay?
The standard solution for Green Bay, according to EPA’s 27-year old Lead & Copper Rule, should have been simple: Adjust the water’s pH and buffering capacity and maybe add a corrosion inhibitor, such as orthophosphate, to inhibit lead’s leaching from lead-containing pipes, solder, and fixtures.
What is the EPA requirement for water?
EPA requires drinking water utilities to take steps to cut lead when amounts rise above 15 ppb. The interior of a corroded cast-iron water pipe is layered with chemical scales and microbial biofilms, all of which influence water quality at the faucet.
What are the components of water pipes?
The water also contains disinfectant; inorganic carbon; iron, manganese, and aluminum compounds; and naturally occurring microorganisms and their nutrients—organic matter, nitrogen, and phosphorus. The inorganic components create complex mineral scales that can trap lead on pipe surfaces or promote its release in particles that travel to the tap, depending on scale composition. The microbes form a slimy biofilm on pipe walls that interacts with the pipe and the water.
What is the lead and copper rule?
Therefore, EPA’s Lead & Copper Rule encourages water systems to tune the pH and buffering capacity of the water to maximize production of insoluble lead carbonates. The rule also endorses the addition of orthophosphate, which forms highly insoluble lead phosphates that coat pipe walls.
What factors affect the amount of lead in water?
A number of factors are involved in the extent to which lead enters the water, including: the chemistry of the water (acidity and alkalinity) and the types and amounts of minerals in the water, the amount of lead it comes into contact with, the temperature of the water, the amount of wear in the pipes, how long the water stays in pipes, and.
Why is lead in water considered a contaminant?
EPA has set the maximum contaminant level goal for lead in drinking water at zero because lead is a toxic metal that can be harmful to human health even at low exposure levels. Lead is persistent, and it can bioaccumulate in the body over time.
How does lead affect the fetus?
Lead can accumulate in our bodies over time, where it is stored in bones along with calcium. During pregnancy, lead is released from bones as maternal calcium and is used to help form the bones of the fetus. This is particularly true if a woman does not have enough dietary calcium. Lead can also cross the placental barrier exposing the fetus to lead. This can result in serious effects to the mother and her developing fetus, including:
What is the lead and copper rule?
To address corrosion of lead and copper into drinking water, EPA issued the Lead and Copper Rule (LCR) under the authority of the SDWA. One requirement of the LCR is corrosion control treatment to prevent lead and copper from contaminating drinking water.

EPA estimates that drinking water can make up 20 percent or more of a person’s total exposure to lead. Infants who consume mostly mixed formula can receive 40 percent to 60 percent of their exposure to lead from drinking water.
How much lead is in a child's blood?
The Centers for Disease Control and Prevention (CDC) recommends that public health actions be initiated when the level of lead in a child’s blood is 5 micrograms per deciliter (µg/dL) or more. It is important to recognize all the ways a child can be exposed to lead.
What is the most common source of lead in water?
The most common sources of lead in drinking water are lead pipes, faucets, and fixtures. In homes with lead pipes that connect the home to the water main, also known as lead services lines, these pipes are typically the most significant source of lead in the water.
How does distillation work?
Distillation Systems use a process of heating water to the boiling point and then collecting the water vapor as it condenses, leaving many of the contaminants behind. Distillation Systems have a very high effectiveness in removing protozoa (for example, Cryptosporidium, Giardia);
What is the pretreatment process for filtration?
Depending on the household’s water needs, pretreatment before filtration may include the addition of coagulants and powdered activated carbon, adjustments in pH or chlorine concentration levels, and other pretreatment processes in order to protect the filter’s membrane surface.
How does reverse osmosis work?
Reverse Osmosis Systems use a process that reverses the flow of water in a natural process of osmosis so that water passes from a more concentrated solution to a more dilute solution through a semi-permeable membrane. Pre- and post-filters are often incorporated along with the reverse osmosis membrane itself.
What is water softener?
Water Softeners. Water Softeners use ion exchange technology for chemical or ion removal to reduce the amount of hardness (calcium, magnesium) in the water; they can also be designed to remove iron and manganese, heavy metals, some radioactivity, nitrates, arsenic, chromium, selenium, and sulfate.
