All field work was observed by the North Andover Health Department .
All percolation. tests were conducted in accordance with the regu-
lations as set by the Sanitary Code, Title 5 , State of Massachusetts.
The results of my finds indicate that the parcel of land is suitable
for the subsurface disposal of sewerage. Certain individual lots
within the subdivision will require alterations in order to comply
with Title 5 of the State of Massachusetts Sanitary Code.
