Health Information
Lead is a toxic metal that can leach from aging pipes and plumbing fixtures.
Even low levels of lead exposure can cause developmental delays in children, kidney damage, and cardiovascular effects in adults. The EPA action level is 15 ppb, but health experts recommend no safe level of lead in drinking water.
Lead enters water primarily through corrosion of lead service lines, lead solder, and brass fixtures — especially in homes built before 1986.
If lead is detected above 1 ppb, consider using a certified lead-removal filter (NSF/ANSI 53) for drinking and cooking water. Run cold water for 30 seconds before use if water has been sitting in pipes.
Common Questions
Based on public water-system records, Highlands, Texas receives an internal US Water Score grade of B (Good) with a score of 84/100. This indicates relatively few system-level concerns in our model, but it is not an EPA safety rating and does not guarantee tap conditions inside individual homes.
ZIP code 77562 is served by 5 water systems using groundwater, surface water sources, providing water to approximately 8,559 people. Multiple source types mean your water may come from a blend of surface and underground sources.
Lead levels in Highlands, Texas are 0.0 ppb, which is at or below the health guideline of 1 ppb. This is a positive result, though periodic testing is still recommended.
Yes — 6 PFAS compounds were detected in records associated with water serving Highlands, Texas, and 1 result exceeded the numerical EPA MCL value used for comparison. UCMR5 occurrence results alone are not a regulatory compliance determination. PFAS rules and compliance timelines are evolving; verify current information with the utility and EPA.
