What about water quality?
According to the EPA, 45% of assessed waters nationwide do not fully meet water quality standards Source: ASCE, et al., September 2004, “All Dried Up: How Clean Water is Threatened by Budget Cuts.”
Also, conditions of coastal areas are largely Fair to Poor. Source: EPA, December 2004, “National Coastal Condition Report II. Office of Research and Development/Office of Water,” EPA-620/R-03/002 (evaluating the overall national and regional coastal condition between 1997 and 2000).
So, there’s a lot to be done
How much will it cost over the next 20 yrs? Between $245 billion and $1.2 trillion Depends on who you ask.
