National Surface Water Survey

Project Description
The National Surface Water Survey (NSWS) was a national surveey
to study lakes and streams which were sensitive to acidic
deposition. Adverse aquatic effects from acidic deposition are
unlikely in areas of the United States that were not sampled in the
NSWS, since surface waters in these areas generally have high acid
neutralizing capacity (ANC), with the possible exception of parts
of the Coastal Plain, in the Southeast.
