   (1)  Watershed surveillance consisting of an inspection of portions of the drainage area or wellhead protection area necessary to identify and evaluate actual and probable sources of contamination. An inspection of a wellhead protection area shall include a review of available information pertaining to possible sources of contamination such as underground storage tanks, onlot disposal systems and other activities that may have an adverse impact on water quality or quantity. Specific hydrogeological studies of sources of contamination are not necessary unless required under §  109.4, §  109.602 or §  109.603 (relating to general requirements; acceptable design; and source quality and quantity) or other rules of the Department.

 (c)  A noncommunity water system which does not collect five or more routine coliform samples per month shall do one of the following:

   (1)  Undergo an initial sanitary survey conducted by the Department by June 29, 1999, and thereafter undergo a subsequent sanitary survey at a minimum of every 5 years after the initial sanitary survey, except that noncommunity systems using only protected and disinfected groundwater shall undergo subsequent sanitary surveys at a minimum of every 10 years after the initial sanitary survey.

   (2)  Increase the number of routine coliform samples collected to at least five samples per month if the Department does not conduct a sanitary survey by June 29, 1999, or within 5 or 10 years using the criteria in paragraph (1), following the initial or a subsequent sanitary survey. This increased sampling frequency shall be in place of the monitoring frequency requirements for coliforms in §  109.301(3)(i) and shall remain in effect through the month in which the next sanitary survey is conducted by the Department.
