The wicked drought that plagued Texas last year had an upside: cleaner beaches.
With the state in the grips of its driest year on record, less polluted runoff from Houston and other cities poured into coastal waters.
As a result, the number of times Texas beaches were closed or had posted advisories because of high bacteria levels in 2011 dropped by nearly half from the previous year, according to a report released by The Natural Resources Defense Council.
Texas' cleaner waters were due, in part, to the record dry spell.
Overall, the state ranked eighth for water quality among the 30 in the survey. The chronically dirty beaches in Corpus Christi and surrounding Nueces County also had cleaner water last year but still accounted for half of the state's beach closings and advisories.
Galveston County, meanwhile, had 13 beaches, including Appfel Park and Steward Beach, where water quality improved or remained the same from 2009.
Even with the assist from the drought, the NRDC said local, state and federal officials could do more to limit polluted runoff, including the use of “green infrastructure,” such as porous pavement that allows rainwater to seep into the ground rather than drain into sewers.
