analysed show any B. Coli present, the well shall
be again disinfected with chlorine solution and
procedures repeated until bacterial sampling and
analysis shows the water pumped to be free from
B. Coli.

Dear Mr. Longacker:
Att'ached are two copies of a revised water supply report for the above project,
dated September 26, 1986. The report basically indicates that the Angel Shores
subdivision is to be expanded from 27 to 51 lots, resulting in a total of 80
units in Angel Shores and The Cove.
As a result, the report indicates that the following changes should be made:
l) A third 30 gpm well should be added (for a firm capacity of 60 gpm on
peak days.)
2) 'Storage should be increased from 40,000 gallons to 54,000 gallons.
We t~ust that the proposed changes will be acceptable to your office. Please
advise if any amendments must be made to applications.
Very truly yours,
~11~am $. Houck
