What Is Lead and Should Cedar Park Residents Be Concerned?
Lead is a toxic heavy metal that enters drinking water primarily through corrosion of older plumbing fixtures, solder, and service lines. There is no safe level of lead exposure, especially for children and pregnant women. Even low concentrations can cause developmental delays, learning difficulties, and long-term health issues. In Cedar park, Texas, most homes built before 1986 may have lead-based solder or fixtures, and some older neighborhoods still have galvanized or lead service lines that corrode over time. Lead does not cause taste, odor, or visible discoloration, so testing is the only way to know if it is present.
I am Eli, a Certified Water Specialist (CWS) with over 20 years of hands-on experience testing and treating residential water systems. I have seen lead show up in homes where homeowners had no idea it was there, and I have also seen families spend money on the wrong treatment before they ever tested their water.
Where Lead Comes From in Cedar Park Homes
Lead rarely originates from the water source itself. Municipal water systems in Cedar Park treat and monitor for lead, but contamination happens after water leaves the treatment plant. The most common sources are brass faucets, chrome-plated fixtures, galvanized pipes installed before the 1960s, and copper pipes joined with lead-based solder before 1986. Homes with private wells are not immune either. Corrosive well water with low pH can leach lead from plumbing components even if the pipes themselves are modern. I regularly test homes where lead spiked only at certain faucets, usually the kitchen or bathroom that had not been updated in decades.
How to Test for Lead in Your Drinking Water
You cannot taste, see, or smell lead, so testing is the only reliable method. I do not recommend DIY lead test strips because they are not sensitive enough for accurate detection at low levels. Instead, request a certified lab test. In Cedar Park, you can contact your water utility to request a free or low-cost lead test, or you can order a certified mail-in test kit from an EPA-recognized laboratory. Collect first-draw water from the tap after it has sat unused for at least six hours, typically in the morning. This gives the most accurate reading of lead that may have leached overnight. If your result shows lead above 5 parts per billion (ppb), treatment is worth considering. The EPA action level is 15 ppb, but many health experts recommend treating at any detectable level, especially in homes with young children.
For general water quality assessment, a Professional Water Test Kit can help you understand hardness, iron, and pH, which may influence corrosion and lead leaching from your plumbing.
What Actually Removes Lead from Drinking Water
The most effective method for removing lead is reverse osmosis (RO). RO systems force water through a semi-permeable membrane that blocks lead, along with other dissolved contaminants like arsenic, fluoride, and nitrates. An under-sink HydroClear™ Reverse Osmosis 50 Gallons per day 5 Stage system is one of the most reliable options I install for lead reduction at the point of use. It is independently tested and certified to remove lead to non-detectable levels in drinking water.
Carbon filters alone do not remove lead effectively. Some activated carbon blocks are certified for limited lead reduction, but they are not as reliable as RO, especially over time. Whole-house carbon systems like those in our whole house water filtration systems improve taste, odor, and chlorine, but they are not designed for heavy metal removal. If you want lead removed from every tap, not just the kitchen, you need a certified whole-house lead filter or a point-of-entry RO system, which is rare and expensive for residential use. Most families in Cedar Park choose point-of-use RO for drinking and cooking water, which is practical and affordable.
Pitcher filters and faucet-mount filters vary widely. Some are NSF-certified for lead reduction, but their capacity is low and they require frequent replacement. I have seen homeowners assume their pitcher was protecting them, only to find out the filter had expired months earlier. If you use a pitcher, check the NSF certification and replace cartridges on schedule.
Common Mistakes I See When Treating Lead
The biggest mistake is treating without testing. I have met homeowners who bought expensive filtration systems because a neighbor had lead, but their own water tested clean. I have also seen the opposite: families who assumed city water was safe and never tested, only to discover elevated lead years later. Another common issue is installing the wrong type of filter. Whole-house carbon systems do not remove lead, and neither do most water softeners. Softeners exchange calcium and magnesium for sodium, but they do not address heavy metals. Some families also forget to maintain their RO systems. Filters and membranes have a lifespan, and performance drops when they are not replaced on schedule. If you install an RO system, plan to replace pre-filters every six to twelve months and the membrane every two to three years, depending on your water quality and usage.

What Cedar Park Homeowners Can Do Right Now
Start with a certified lab test. If lead is detected, install a point-of-use reverse osmosis system at your kitchen sink for drinking and cooking water. If you have young children or are pregnant, do not wait for high results to take action. Flush your taps for 30 seconds to two minutes before using water that has been sitting in the pipes overnight. Use only cold water for drinking and cooking, since hot water leaches more lead from plumbing. If you are replacing fixtures, choose NSF-certified lead-free faucets and avoid brass unless it is certified lead-free. Finally, if you live in an older home and plan to renovate, consider replacing galvanized pipes and lead solder during the project.

Frequently Asked Questions
Does boiling water remove lead?
No. Boiling water does not remove lead. In fact, boiling can concentrate lead because it evaporates water but leaves dissolved metals behind. Use a certified reverse osmosis or lead-reduction filter instead.
Can a water softener remove lead from drinking water?
No. Water softeners exchange hardness minerals like calcium and magnesium for sodium, but they do not remove heavy metals such as lead. You need a reverse osmosis system or certified lead filter for that.
How often should I test my water for lead in Cedar Park?
Test at least once if you live in a home built before 1986 or have galvanized plumbing. Retest every two to three years, or after any plumbing work that could disturb pipes or solder.
What is the EPA action level for lead in drinking water?
The EPA action level is 15 parts per billion (ppb). However, health experts recommend treating at any detectable level, especially in homes with children or pregnant women, since no amount of lead is considered safe.
Will a whole house carbon filter remove lead?
No. Most whole-house carbon filters are designed to remove chlorine, taste, and odor, not heavy metals like lead. For lead removal, you need a point-of-use reverse osmosis system or a whole-house filter specifically certified for lead reduction.
