Melbourne's drinking water received a grade of A (92.4 out of 100), indicating excellent water quality. The city's 1 water system serves approximately 765 residents using purchased ground water.

Lead levels were measured at 5.7 ppb (90th percentile), which is within EPA limits but above recommended levels. This system has not yet been tested for PFAS under the EPA UCMR 5 program. The system has 5 violations on record, including 1 health-based violation. 1 remains unresolved.

Melbourne ranks #90 out of 430 cities in Iowa for water quality, placing it above average in the state. Melbourne purchases its water from a regional wholesaler, meaning quality depends on both the supplier's treatment and the local distribution system's condition. While lead levels are within EPA limits, they are above the recommended 5 ppb threshold that health organizations consider ideal. A point-of-use filter adds an extra layer of protection. As a small community water system, Melbourne may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.

04Where Melbourne's water comes from

Melbourne purchases its water supply from a regional wholesale provider rather than treating raw water directly.

Source

Purchased Groundwater

Water is bought from a regional wholesaler; quality starts at the supplier's intake and treatment.

Treatment

Wholesale supplier

Primary treatment happens at the wholesaler; the local utility maintains disinfectant residual in its pipes.

Distribution

1 system

1 water system, operated under local government ownership.

Delivery

765 people

Residents served across Melbourne's service area.

Water quality depends on both the wholesaler's treatment standards and the condition of Melbourne's local distribution pipes and storage facilities. Purchased water systems are common in suburban areas and smaller communities that lack the infrastructure for independent treatment. The system is operated by local government ownership and serves approximately 765 people through 1 water system.

Flush taps & check your service line

Lead leaches from pipes as water sits. Run cold water 30 seconds before drinking (especially mornings), and ask the utility whether your address still has a lead service line.
