Glossary of
Water Quality Terms
"Ambient
Water Quality" means water quality of a water body measured immediately
upstream (or outside) of the influence of a particular source of pollutants or pollutant
parameters during average flow conditions. This is the water quality that the Department
shall utilize as the means water quality when implementing the antidegradation policies on
a site-specific basis as defined in N.J.A.C. 7:9B 1.1.
"Antidegradation" means the
limitation of changes in mean water quality or quantity to protect existing and designated
uses, to maintain that quality which is better than the applicable criteria, and to
prevent any additional lowering of water quality or quantity where those levels are
already below the criteria or levels necessary to support the existing or designated uses.
"Aquifer" means a geologic
formation, group of geologic formations, or a portion of geologic formations capable of
yielding a significant amount of groundwater to wells or springs.
"Assimilative capacity" means
the total assimilative capacity of a watershed, water body or a water body segment to
receive natural and anthropogenic sources of pollutants (from point and nonpoint sources),
while maintaining surface water quality standards, use classifications and the designated
use(s) of the watershed, water body or water body segment. When, derived, the Total
Maximum Daily Load represents, or defines, the total assimilative capacity of a water body
segment. (OK definition?)
"Baseflow" means that quantity
of streamflow contributed by ground water sources. It is estimated by employing a
hydrograph separation method whereby long-term streamflow records are reconstructed so
that the majority of stormwater flows are subtracted from those records to theoretically
arrive at the ground water contribution to the stream, or through other methods approved
by the Department.
"Best Management Practices" or
"BMPS" for purposes of this chapter means:
- Schedules of activities, prohibitions of practices,
maintenance procedures, and other management practices to prevent or reduce the pollution
of the waters of State; or
- Methods, measures or practices selected by an agency to meet
its nonpoint source control needs. BMPs also include treatment requirements, operating
procedures, and techniques to control site runoff, spillage or leaks, sludge or waste
disposal, or drainage from raw material storage. BMPs include, but are not limited to,
structural and nonstructural controls and operation and maintenance procedures. BMPs can
be applied before, during, and after pollution producing activities to reduce or eliminate
the introduction of pollutants into receiving waters.

of implementing the antidegradation policies as set forth at N.J.A.C. 7.9B-1.5(d), for
protection from changes in water quality that fall outside of the 95% confidence interval
of the existing, appropriate, mathematical mean water quality because of their clarity,
scenic setting, other characteristics of aesthetic value, exceptional ecological
significance, exceptional recreational significance, exceptional water supply
significance, or exceptional fisheries resource(s). These waters may include, but are not
limited to:
