From the 2023 Annual Water Quality Report:
“The City of Portsmouth Waterworks customers are fortunate because we enjoy an abundant water supply from the Ohio River. The Ohio Rivers begins in Pittsburgh, Pennsylvania and then travels 350 miles to Portsmouth. The treatment process consists of a series of steps. First, raw water is drawn from our water source and sent to an aeration tank which allows for oxidation of high iron levels. The water then goes to a mixing tank where polyaluminum chloride soda ash are added. The addition of these substances cause small particles called floc to adhere to one another making them heavy enough to settle into a basin from which sediment is removed. “

*Note that drinking water information provided on this site is aggregated from the federal EPA database, state resources and local government sources where available.
EPA publishes violation and enforcement data quarterly, based on the inspection reports of the previous quarter. Water systems, states and EPA take up to three months to verify this data is accurate and complete.
Specific questions about your local water supply should be directed to the facility.
The EPA safe drinking water facilities data available to the public presents what is known to the government based upon the most recently available information for more than one million regulated facilities. EPA and states inspect a percentage of facilities each year, but many facilities, particularly smaller ones, may not have received a recent inspection. It is possible that facilities do have violations that have not yet been discovered, thus are shown as compliant in the system.
EPA cannot positively state that facilities without violations shown in ECHO are necessarily fully compliant with environmental laws. Additionally, some violations at smaller facilities do not need to be reported from the states to EPA. If ECHO shows a recent inspection and the facility is shown with no violations identified, users of the ECHO site can be more confident that the facility is in compliance with federal programs.
The compliance status of smaller facilities that have not had recent inspections or review by EPA or the states may be unknown or only available via state data systems.
