What is in the water at 32746

4 public water systems serve this ZIP code in the federal records. Everything below comes from EPA monitoring data, and everything missing is named.

LAKE MARY, CITY OF

PWSID FL3590201 · FL · serves 17,066 people

PFAS and lithium

4 compounds detected at or above the reporting limit under EPA’s UCMR 5 monitoring, across 7 samples.

CompoundHighest detectedSamplesMost recent
PFHxA0.0042 µg/L24/9/2024
PFPeA0.0041 µg/L24/9/2024

PFHxS0.0036 µg/L14/9/2024

A detection is a measurement, not a violation and not a health finding. EPA states that UCMR 5 results do not indicate compliance or non-compliance with any limit.

Health-based violations

No open health-based violation on record. This covers MCL, treatment technique and MRDL violations in SDWIS that have not been returned to compliance. It excludes monitoring and reporting violations, which are the large majority nationally, so this is not “no violations”, and SDWIS completeness varies by state.

Hardness

No hardness measurement. Hardness is measured at environmental monitoring stations, and none fell inside this system’s service area. That is a gap in where monitoring happens, not a finding about the water.

SEMINOLE COUNTY NORTHEAST

PWSID FL3590473 · FL · serves 19,925 people

PFAS and lithium

Sampled, nothing detected. Tested for 30 compounds under UCMR 5 with none found at or above its reporting limit. A reporting limit is the lowest concentration the method can measure, so this means “below that” rather than “zero”.

Health-based violations

No open health-based violation on record. This covers MCL, treatment technique and MRDL violations in SDWIS that have not been returned to compliance. It excludes monitoring and reporting violations, which are the large majority nationally, so this is not “no violations”, and SDWIS completeness varies by state.

Hardness

Too few readings to state a hardness. 1 station(s), 10 result(s). Below two stations and five results this page will not state a number: a median of two readings from one creek is not your water.

SEMINOLE COUNTY NORTHWEST

PWSID FL3594107 · FL · serves 31,986 people

PFAS and lithium

Sampled, nothing detected. Tested for 30 compounds under UCMR 5 with none found at or above its reporting limit. A reporting limit is the lowest concentration the method can measure, so this means “below that” rather than “zero”.

Hardness

Median hardness 139 mg/L as CaCO₃, measured at 2 stations serving this system across 11 results, 2015-01-13 to 2016-04-18. Measured in the water source and distribution area, not at a tap, and not in your home.

CHASE GROVES(CONSEC.)

What this report cannot tell you

Every figure describes water at a sampling point: a treatment plant, an entry point to the distribution system, or a monitoring station. None of it describes water arriving at your tap. Plumbing between the two can add lead and copper, and if your home was built before 1986 a test kit tells you something no federal dataset can.
