Myth: "Lead levels in my home’s water are the same as those measured in the public system."
Government data for the Rehoboth Pump District public water system, serving Sussex County’s Rehoboth Beach area, reports a 90th percentile lead concentration of 0.00071 mg/L based on samples taken at plumbing distribution points near the end of 2024. It is important to understand this figure does not reflect the lead concentration in groundwater or water entering your home. Instead, it represents lead sampled at household taps, influenced by plumbing materials and water use patterns.
Myth: "Lead in groundwater is the primary source of lead in Rehoboth Beach water."
While the water source for the Rehoboth Pump District is groundwater, lead itself does not commonly occur naturally in groundwater at concerning levels. Lead presence in household water more often arises from corrosion or leaching in distribution pipes, service lines, or internal plumbing within residential homes. So, the lead figure in system records reflects both public system water quality and plumbing factors.
Myth: "Lead levels remain constant throughout the year in Rehoboth Beach water."
Seasonal and multi-year variation in lead concentrations can happen due to changes in water chemistry, temperature, and flow dynamics affecting corrosion in plumbing. The recorded 90th percentile value from late 2024 represents a snapshot in time, but lead levels in your home’s water could vary depending on these factors. Regular testing of your household water over time is necessary to understand your specific exposure.
Myth: "Lead is the same problem as other common water quality issues like iron or hardness."
Lead is a heavy metal that can pose health concerns if ingested over time, unlike iron or hardness minerals which primarily affect taste, staining, or scale buildup. Lead requires specific treatment technologies designed to reduce dissolved lead or prevent its leaching, rather than addressing only aesthetic or scaling issues.
Myth: "Public water system records tell me exactly how much lead is in my private well water."
Public water system records cover water quality at points managed by the system, including sampled household taps within that system’s service area. They do not represent private well water or individual home plumbing conditions outside the system. To know the lead level in your well water or home plumbing, you must conduct your own water test from the tap where water is used.
For households in Rehoboth Beach weighing treatment options, the Fleck Lead in Water Filter offers a documented solution. This Fleck System ships ready to configure and addresses lead removal based on the demand volume you measure in your home, providing an effective approach tailored to residential lead concerns.
