shall be submitted to the Board of Health for approval and
the well contractor shall be responsible for all data
submitted.
3.4 A quantitative analysis is required for EPA 624 volatile organic
compounds, or its equivalent as approved by the Board of Health. If in
the opinion of the Board of Health its standard analysis, as described in
these regulations shows no significant changes in the general water
quality produced by the well between the first and second samples, the
requirement for a second volatile organics analysis for the tap sample
prior to the occupancy may be waived. The first sample shall be taken
directly from the well. The second sample shall be taken from a bathroom
or kitchen tap in the building.

Regulation 9: Abandonment or Treatment of on-site water
supply wells found to be contaminated
At the time of connection to the Town Water System of a property having a
private on-site well water supply, such water supply shall be sampled and
tested. Otherwise, such private well water supply shall be abandoned in a
manner as provided herein.
Any water supply well found to be contaminated With any chemical compound
in excess of the Maximum Contaminant Level (MCL) as determined by the
U.S.E.P.A., or the Commonwealth of Massachusetts, Department of
Environmental Protection (DEP) or the Norfolk Board or Health shall be
abandoned, filled, and capped within 120 days of connecting to the Town
of Norfolk Water Supply System. If the water analysis shows the well to
be contaminated, it may be re-sampled and tested within 30 to 45 days
following the initial sampling. If the second test shows no
contamination, a third sampling and analysis shall be performed within 30
and 45 days from the second sampling in order to verify the results. If
the second and third tests show no contamination, the well shall be
considered not contaminated at the time of that sampling.
Such abandoned well shall be filled with low permeability soil except for
the upper 5 feet which shall be filled with Portland Cement Mortar or
concrete. Such well less than 15 feet shall be completely filled with
Portland Cement Mortar or concrete.
State law requires that plugging of abandoned wells must be performed by
a registered well driller.
All water supply lines from such well, which are inside the
building and served by the well, shall be removed. Cross
connection of a private well with the Town Water Supply is
prohibited.
Should the Town Water Supply not be available, appropriate treatment, in
a manner acceptable to the Board of Health, shall be provided such that
the water Quality is in compliance with standards of the U.S.E.P.A. and
the Massachusetts DEP and the Norfolk board of Health for such compounds.
A maintenance and testing program satisfactory to the Board of Health
shall be implemented.
PROCEDURE FOR APPROVAL OF WATER SUPPLY, PRIOR TO OBTAINING
BUILDING PERMIT
PRIOR TO APPROVAL OF ISSUANCE OF A BUILDING PERMITS THE WELL WATER SAMPLE
MUST EITHER BE FREE OF VOLATILE ORGANICS (VO) OR NOTICE OF ITS PRESENCE
MUST SE RECORDED AT THE REGISTRY OF DEEDS.
IF THE INITIAL SAMPLE SHOWS THE PRESENCE OF VO’S, IT IS ALLOWED TO BE
RESAMPLED. WHEN A “CLEAN SAMPLE” IS OBTAINED, IT WILL BE APPROVED FOR
ISSUANCE OF A BUILDING PERMIT.
PRIOR TO OCCUPANCY, THE WATER MUST BE SAMPLED AGAIN. THIS
TIME THE SAMPL£ MUST BE COLLECTED BY THE TESTING LABORATORY.
IF THIS SAMPLE IS CLEAN THE WATER SUPPLY IS APPROVED AS FAR
AS VO'S ARE CONCERNED.
IF VO'S ARE DETECTED, THE NOTICE IN THE REGISTRY OF DEEDS,
ALONG WITH TREATMENT IS REQUIRED.
ALTERNATELY, IF AFTER A SAMPLE SHOWING THE PRESENCE OF VO’S IS OBTAINED,
TWO SUCCESSIVE SAMPLES SHOW NO VO'S DETECTED, THE WATER WILL BE APPROVED.
