City pools will be closed Wednesday for extra chlorine treatment at the request of the Tarrant County Public Health Department.
The health department has recommended hyperchlorination treatment for all area public pools as a precaution after at least 16 people came down with a waterborne illness that health officials believe may be related to Burger's Lake in northwest Fort Worth. The illness is caused by a chlorine-resistant parasite called cryptosporidium; it can cause diarrhea and severe abdominal pain.
The parasite, known as "crypto," has not been found in any Arlington public pools, park officials said Tuesday.
"We are following the health department's recommendations as a matter of precaution," said Bill Gilmore, Arlington's parks and recreation assistant director. "We want to assure the public our water is safe."

Arlington pools are scheduled to reopen Thursday.
Burger's Lake remains closed as health officials await lab test results on whether the parasite was found in the popular swimming spot.
