The US EPA estimates that changes due to global warming will cause higher water temperatures in our lakes and streams, along with increases in storms AND droughts in the Southeast? These changes will mean increased pollution and decreased oxygen levels in our waterways. Some of these issues can be addressed with improved management practices. - source
Water quality impacts will occur due to increased runoff after longer dry periods - increasing pollutant loading of the runoff. Sites should be designed with significant areas of pervious landscape, and allowing rainwater to percolate naturally into the ground. In addition, there are structural approaches to remove sediment loading and consequently remove trace contaminants from runoff. These measures can take very little land area, which is important on urban sites. The downside is that there is a regular maintenance schedule that must be followed to ensure that the management practice put into place actually functions year to year.
