Lead is not present in Escondido’s source water, and the city does not add it. Where lead turns up in tap water, it enters somewhere between the water main and the faucet – from service lines, solder, brass fittings and fixtures inside individual buildings – which makes it a house-by-house question rather than a citywide one. Lead is a toxic metal that can cause severe health problems, especially in children and pregnant women. When consumed, lead can accumulate in the body over time and lead to developmental delays, learning difficulties, and behavioral problems. Additionally, lead exposure can also result in kidney damage, high blood pressure, and reproductive issues. Studies show that lead at even its most minute levels can cause neurological, learning and IQ defects in children, and that these lower levels but widespread exposures can have large health effects.

Where lead does appear, aging infrastructure is usually the reason. Some older homes and buildings still have lead solder, galvanized pipe or brass fixtures that can leach lead into the water. As these pipes corrode over time, the lead particles can mix with the water supply, making it unsafe for consumption. This issue is particularly concerning as lead exposure is often undetectable, with no taste or odor, making it difficult for residents to identify the problem.

The lack of awareness and testing for lead in the water exacerbates the issue. Many residents may not be aware of the potential risks associated with lead contamination or the steps they can take to mitigate it. Regular testing of the water supply is crucial to identify areas with high lead levels and take appropriate measures to address the problem.

However, without proper monitoring and education, residents may unknowingly continue to consume lead-contaminated water, putting their health at risk.

Because the risk depends on what your own pipes and fixtures are made of, a citywide result cannot tell you what is coming out of your tap. Testing your own water is the only way to know where your household actually stands.

Lead contamination in water is a serious health concern that affects the residents of Escondido. In addition to its once widespread use, and continued use in some plumbing fittings and solder, lead is virtually undetectable in water. Since you can’t see, taste, or smell it, prolonged exposure can be common. Lead in drinking water is especially harmful for young children and pregnant women, but is not safe for anyone to consume, in any concentration.

One of the major health concerns associated with lead exposure is its impact on the nervous system. Lead can cause developmental delays and learning disabilities in children, leading to long-term cognitive impairments. Additionally, it can affect the cardiovascular system, leading to increased blood pressure and an increased risk of heart disease.

Lead exposure is particularly dangerous for pregnant women as it can cross the placenta and harm the developing fetus. It can result in premature birth, low birth weight, and developmental issues in newborns.

For children, the effects of consuming lead-contaminated water are especially high. Once consumed, lead remains in our bodies or ‘bioaccumulates’, as we can’t flush the contaminant from our system. Once there, lead can cause serious behavioral and cognitive problems for children, and over time it can lead to:

Furthermore, lead can accumulate in the body over time, causing chronic health problems. It can damage the kidneys, impair the reproductive system, and even lead to cancer.

To address these health concerns, it is crucial for the residents of Escondido to be aware of the potential lead contamination in their water supply. Regular testing of water sources, especially in older homes, is essential to identify and mitigate lead exposure risks.

Lead also crosses the placenta, so it’s especially important for pregnant women to avoid drinking water contaminated with lead. In addition to harming the mother, it can cause stunted fetal growth and premature birth.

For the average adult, lead exposure from water can cause heart and cardiovascular issues, reduce kidney function, and contribute to reproductive problems.

The degree and severity of these issues depends on how much lead you’ve been exposed to, and how much is stored in your body, though governing health authorities like the Centers for Disease Control (CDC) caution that no amount of lead is safe.

In its 2024 water quality report, the City of Escondido sampled 57 homes for lead and found none above the 15 parts per billion action level, with every result below the laboratory’s reporting limit of 5 ppb. That is a real result, and it is worth being precise about what it does and does not say. The action level is a trigger for utility-side corrosion control, not a health-based safety line – California’s public health goal for lead is 0.2 ppb, far below the 5 ppb the lab reports down to, so a result of “none detected” at 5 ppb does not establish that a home sits under the health goal. And because lead comes from each building’s own plumbing, a 57-home sample describes the system, not your house.

1. What is the current status of lead in Escondido’s water supply?
The city’s most recent round of lead sampling, reported for 2024, found no home above the federal action level and no result above the laboratory’s reporting limit. The city monitors the distribution system and treats the water to control corrosion. What that testing cannot cover is the plumbing inside any particular home – old solder, galvanized pipe and brass fixtures are the usual sources of lead at the tap, and they vary house to house.

2. How can I determine if there is lead in my home’s plumbing system?
If you are concerned about lead in your home’s plumbing system, you can have your water tested by a certified laboratory. They will analyze the sample and provide you with accurate information about the presence of lead. Additionally, you can check if your plumbing system contains lead pipes or fixtures, especially if your home was built before the 1980s. A professional plumber can help you identify and replace any lead components if necessary.

5. What is the city of Escondido doing to address lead concerns?
The city tests the distribution system for lead on the schedule the state requires, treats the water to limit corrosion of household plumbing, and publishes the results each year in its water quality report. It also provides residents with information on lead testing, the common sources of lead in a home, and steps to reduce exposure, and encourages residents to report any concerns about lead in their water.

Lead is worth taking seriously precisely because it gives no warning. It has no taste, no color and no smell, the health effects fall hardest on children and pregnant women, and the source is the plumbing inside the building rather than anything the utility delivers. That combination means one home can be fine and the house next door not, regardless of what the citywide numbers say, and testing is the only way to tell the difference.

In the U.S., 14-20% of lead exposure is attributed to drinking water. Municipalities have taken action over the past 30 years to ban lead solder, reduce corrosivity and remove lead from brass faucets and water meters, and these measures have significantly helped exposure issues.

Lead lends itself very easily to building pipes – like those used for transporting water. It’s malleable, relatively cheap to use and, as a result, its use in plumbing dates back to early Roman cities. Lead piping was also the standard in the United States until the 1920s and 30s, when concerns about lead poisoning became better understood.

The most common way lead can enter a drinking water system is through corrosive aging pipes and plumbing infrastructure. Many homes, and sometimes entire communities, have plumbing infrastructure that has not been updated for decades, and sometimes more than a century.

These homes are at high risk for lead contamination, even if the water coming through it has been properly treated.

When pipes, fitting or solder have become corroded, water can become contaminated.

The best way to avoid a lead problem is to never have one. Despite the ongoing issues in many cities throughout America, many homeowners are simply not keen on getting a simple water test.

A test can determine whether there is lead in your household’s tap water, and whether exposure can be reduced in the interim by flushing the line for a specified amount of time. Knowing that can be the difference between avoiding lead exposure and living with it unaware.

The Flint Crisis was a situation where the water was improperly treated – specifically, a severe act of negligence on the part of public officials failing to add corrosion inhibitors to the water. Given how much scrutiny that failure brought to corrosion control, a repeat on that scale is far less likely today.

However, that doesn’t mean all water in your home is safe. Even treated water can leach lead into its supply if your pipes or fixtures are made of lead.

The final tally on the Flint Water Crisis, which included e.coli bacteria, THMs, lead, and a Legionnaire’s disease outbreak, resulted in 6,000 to 12,000 children exposed to lead and a slew of lawsuits, investigations, resignations and criminal indictments.
