Consumer Notice of Tap Water Results for May 2025
Meets or exceeds state and federal lead and copper drinking water standards
May 19, 2025
May 19, 2025
Wright State’s public water system (PWS) collects both routine compliance samples and non-compliance special purpose samples for lead and copper analysis.
On May 7-8, 2025, seven (7) special purpose tap water samples were collected and analyzed for lead and copper. The monthly special purpose samples are required while the drinking water membrane system is undergoing maintenance. The seven samples tested were all below the federal action level of 15.5 ppb. They ranged from less than 2.0 to 8.1 ppb, which is considered safe to drink.
The lead and copper results for the 7 Special Purpose samples collected in May 2025 are available in the report link below or on the Environmental Health and Safety website, under the May 2025 Consumer Notice.
Consumer Notice (CN) for May 2025
Ohio EPA requires that results for individual tap samples given to the owner and persons served at the tap, along with information about lead. This Consumer Notice is required for all lead tap samples, both compliance and special purpose. These results must be communicated to the consumer and to reach all users of the tap. To ensure this, Wright State emails the entire campus community, posts at the tap location, and makes the results available on-line. Many cities and municipalities include this information in their consumers water bills.
When do I get notified of the lead and copper results?
ASAP but no later than 2 business days after receipt of sample result, regardless of result.
Why were Special Purpose lead and copper samples collected?
Ohio EPA requires that an additional seven non-compliance or special purpose samples to be collected monthly while the water plant’s membrane system is undergoing maintenance. During this time, tap water will have increased hardness, alkalinity, and chloride concentrations and is considered safe to drink. The membrane system will be back in service as the maintenance activities are completed.
Under the authority of the Safe Drinking Water Act, the U.S. Environmental Protection Agency (EPA) established the action level for lead in drinking water at 15.5 µg/L. This means PWSs must ensure that water from taps used for human consumption do not exceed this level in at least 90 percent of the sites sampled (90th percentile value). The action level is the concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a PWS must follow. Wright State's 90th percentile value is 5.5 µg/L, which is less than the 15.5 µg/L action level for lead in drinking water.
In 2018, Ohio EPA established the threshold level for lead in drinking water at 15.5 µg/L. The lead threshold level is the concentration of lead in an individual tap water sample which, if exceeded, triggers additional notification requirements for those served by the tap sampled.
Because lead may pose serious health risks, US EPA established a Maximum Contaminant Level Goal (MCLG) of zero for lead. The MCLG is the level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.
Lead can cause serious health problems if too much enters your body from drinking water or other sources. It can cause damage to the brain and kidneys, and can interfere with the production of red blood cells that carry oxygen to all parts of your body. The greatest risk of lead exposure is to infants, young children, and pregnant women. Scientists have linked the effects of lead on the brain with lowered IQ in children. Adults with kidney problems and high blood pressure can be affected by low levels of lead more than healthy adults. Lead is stored in the bones, and it can be released later in life. During pregnancy, the child receives lead from the mother’s bones, which may affect brain development.
Health Screenings and testing of blood lead levels are available through your personal health care provider. The Physician can determine if an exposure warrants testing and can be available to interpreting the results.

Greene County Public Health, the Ohio Department of Health (https://odh.ohio.gov/wps/portal/gov/odh/know-our-programs/Childhood-Lead-Poisoning/about-lead/) and the Ohio EPA ( https://epa.ohio.gov/divisions-and-offices/drinking-and-ground-waters/public-water-systems/lead-and-copper-in-public-water-systems) provide additional information about lead levels.
Lead is a common, natural, toxic, and often useful metal that was used for years in products found around the home. It can be found throughout the environment in lead-based paint, air, soil, household dust, and certain types of pottery, porcelain, and pewter. Although most lead exposure, especially in children, occurs when paint chips are ingested, dust inhaled, or absorbed from contaminated soil, the U.S. EPA estimates that 10 to 20 percent of human exposure of lead may come from lead in drinking water.
Lead is unusual among drinking water contaminants in that it seldom occurs naturally in water supplies like rivers and lakes. Lead enters drinking water primarily as a result of corrosion, or wearing away, of materials containing lead in the plumbing. Buildings built prior to 1986 are more likely to have lead pipes, fixtures, and solder. New buildings can also be at risk, since even legally ‘lead-free’ plumbing may contain up to 8 percent lead. The most common problem is with brass or chrome-plated brass fixtures which can leach significant amounts of lead into water, especially hot water.
