Orlando water quality and hardness: what OUC reports.
OUC’s information separates water characteristics from measured contaminants. Both are useful, and each answers a different question.
First identify the supplier
OUC supplies Orlando and parts of Orange County. Its FAQ gives an average water hardness of 129 ppm, or 7 grains per gallon. This is an operator-wide reference, not a measurement at a particular address or a figure for every Central Florida utility.[2]
Read the 2025 monitoring results
The report lists total trihalomethanes at 72.17 ppb against an MCL of 80 ppb, with no violation for that parameter. It uses a locational running annual average, which may include earlier quarters. The report also states that no lithium or any of the 29 monitored PFAS were detected in the October 2024 and April 2025 monitoring rounds.[1]
Keep observations in context
OUC’s FAQ discusses household plumbing as a possible source of lead or copper and encourages customers to investigate treatment-device claims. It neither recommends nor discourages a particular point-of-use device. A discussion about taste or hardness should therefore remain separate from a conclusion about a specific contaminant.[2]
A useful brief for a local project
Bring together the supplier’s report, the intended use and any analysis from the actual installation. Make sure a comparison uses the same units and sample period. A published average or a non-detection in a monitoring round cannot be turned into a permanent guarantee about every property.
The key to reading it
Hardness, compliance values and non-detections describe different things. Keep the source and period attached to each when evaluating local needs.
