In short: very little. Currently, there is no danger posed by drinking water on campus.
The violation was a result of increased levels of trihalomethanes (TTHMs) that occurred during spring 2014. TTHMs are a group of chemical byproducts created when chlorine is used to disinfect water sources, according to the Environmental Protection Agency.
"Some people who drink water containing total trihalomethanes in excess of the [average levels] over many years could experience liver, kidney or central nervous system problems and increased risk of cancer," according to the EPA.
Current standards for safe drinking water mandate that average levels of TTHMs not exceed more than 80 parts per billion throughout the year. TTHM levels exceeded safe levels only in the first quarter of 2014, reaching 114.05 ppb. Testing in the remaining three quarters registered TTHM levels below the recommended levels of 80 ppb.
The school has since adjusted its water treatment practices to come back in line with government regulations.
"Since elevated TTHM levels were found at the CFE Arena sampling site in the spring, UCF has increased the flushing of pipes to make the water move faster. UCF also has adjusted the amount of chlorine added at the water treatment plant and expanded monitoring and tracking through a computerized maintenance management system," according to a press release from UCF.
