In El Paso, a local utility authority has achieved a streak of compliance with arsenic standards. This compliance has been consistent over several quarters. The authority operates facilities that treat arsenic, and these facilities have been found to meet requirements.

The assessment of these facilities is based on a specific average calculated over a year. Further information about this development can be found through local news sources, such as KTSM 9 News, which reported on the utility authority's performance in recent tests.
