§64-4-4. Classification of Public Water
Systems.
4.1. A public water system is classified on
the basis of the complexity of water treatment
processes.
4.1.a. Class 1D: All transient non-
community water systems that have ground
water only as a source, and do not use gaseous
chlorine or chlorine dioxide as a means of
disinfection, and do not treat for the removal of
nitrate or nitrite, or both. Ground water sources
that use gaseous chlorine, chlorine dioxide as a
means of disinfection or have treatment for
removal of nitrate or nitrite, or both, are
considered a Class I public water system.
4.1.b. Class WD: A public water
system that obtains all of its water from another
public water system, and is not owned or
operated by the supplying public water system.
The system does not have any other source of
water other than water from the supplying public
water system. A WD system may apply chorine
for supplemental disinfection.
4.1.c. Class I: Community and non-
transient non-community public water systems
that use ground water only, serve a population of
less than 10,000 (including consecutive
connection population), and do not treat for a
primary contaminant.
4.1.d. Class II: All public water
systems that use a surface source or a ground
water under the direct influence of a surface
water source, serve a population of less than
10,000 (including consecutive connection
population), and do not have any additional
treatment units within the treatment plant for
identified primary contaminants in the source
water. Treatment installed for removal of
Cryptosporidium is considered an additional
treatment unit. Class II also includes all public
water systems that use ground water only, serve
less than 10,000 population, use at least one
radial water collector well as a source, or treat
