Surface water sampling conducted by the Bandera County River Authority and Groundwater District (BCRAGD) still list e. coli levels at Bandera City Park at Hwy 173 as being over 2,420 most probable number (MPN), which is the maximum possible reading.
TCEQ labels anything over 399 MPN as hazardous.
Activities involving full submersion of the head underwater are strongly discouraged in places where counts exceed 399 MPN.
BCRAGD tests conducted on July 7 showed e. coli levels of 2,420 MPN, though other locations that showed high e. coli levels were back to safe MPN levels on the latest tests.
Bandera River Ranch Park, which returned levels of 866 MPN earlier this month, is now listed at 62 MPN.
English Crossing, listed at 816 MPN earlier this month, returned results of 75 MPN.
Medina Lake at Pop’s Place, which showed 770 MPN, is now listed at 10 MPN, according to BCRAGD’s test results.
Bridlegate Park, listed earlier this month at 594 MPN, now shows 76 MPN.
Safe e. coli levels were showed throughout the county, with the highest being Tarpley Crossing (161 MPN) and the lowest being Can Creek at Lost Maples and Medina Lake at Red Cove, which both showed levels less than one MPN.
