The length of the advisories depends on the time it takes for the sewer systems to return to normal levels.</p><p>The CSO alerts do not prohibit recreational river activity, but advise the public to reduce water contact, especially those with weak immune systems or open cuts and sores.</p> Fri, 24 May 2013 17:22:59 +0000 Michael Lynch 10161 at http://wesa.fm EPA: Two-Thirds Of PA River Miles in Poor Health for Aquatic Life http://wesa.fm/post/epa-two-thirds-pa-river-miles-poor-health-aquatic-life <p>More than half of the nation’s river and stream miles are in poor condition for aquatic life.
