TOWN OF WAPPINGER SUPERVISOR'$OFFICE - 20 MIDDCEBUSH ROAD P.O. BOX 324 ` IRENE M. PAINO W.APPINGERS FALLS, NY 1.2590-0324 SUPERVISOR 9 January 29, 1986 Mr. Peter Marlow Dutchess County Health Department 22 Market Street Poughkeepsie, NY 1.2601 Dear Mr. Marlow: This letter is in response to your letters regarding the inspection of the Town. Water Systems. I have consulted the Operators of the Town Water System, CAMO Pollution Control, Inc. , and have directed the following action: FLEETWOOD MANOR WATER DISTRICT 1. As was noted in your letter, we intend to install a lead lag alternation system for the facilities pneumatic pumps. Incorporated within this is a low water cut-off for the pumps and a low level alarm. Monies have been allocated for these improvements in the 1986 0 & M Budget. Wank on this system will begin as soon as possible. 2. On January 15, 1986, CAMO Pollution Control, Inc. personnel collected a water sample from the Fleetwood System and had it analyzed for sodium. The results of this analysis are to be found on the enclosed data sheet. 3. The addition of Sodium Hexametaphosphate has been approved and the Town has authorized CAMO Pollution Control, Inc. to install these systems. CAMO Pollution Control, Inc. hopes to have these systems in full operation by March 1, 1986. TAIL TREES WATER DISTRICT 1. CAMO Pollution Control, Inc. personnel have collected samples to be analyzed for inorganics and the results of this analysis should be in your possession by February 1, 1986. 2. On January 15, 1986,. CAMO Pollution Control, Inc. personnel collected a water sample from the Tall Trees Water System and had it analyzed for sodium. The results of this analysis are to be found on the attached date sheet. Mr. Peter Marlow Dutchess County Health Department January 29, 198 6 Page 2 TALL TREES WATER DISTRICT (Cont.) 3. Since maintaining a chlorine residual at all locations throughout the system is nearly impossible without the proper detention time for chlorine mixing, CAMO Pollution Control, Inc. maintains this situation in the following ways: 1) Maintain a 0.3 to 0.5 ppm residual at the pump house. 2) Maintaining a 0.2 to 0.4 residual at the first hydrant on the system. 3) Monitoring the results of coliform samples taken at random areas in' the system along with monitoring the residuals at these random areas. As of this date, no problem with the coliform results has occurred and we feel the disinfection process is being carried out effectively. OAKWOOD KNOLLS WATER DISTRICT 1. CAMO Pollution Control, Inc. personnel have collected samples to be analyzed for inorganics and the results of this analysis should be in your possession by February 1, 1986. CENTRAL WAPPINGERS WATER IMPROVEMENT AREA - ROCKINGHAM FARMS WATER DISTRICT 1. Due to the age and poor condition of this facilities control building, monies have been allotted in the 1986 Budget for major improvements to this facilities internal piping and deteriorating exteriors. Work on these problems will begin as soon as possible. 2. Since it is nearly impossible to maintain chlorine residual throughout the system without the proper chlorine detention tank, CAMO Pollution Control, Inc. monitors the system in the following ways to assure proper water quality: 1) Maintaining a 0.3 to 0.5 ppm residual at the control building. 2) Maintaining a 0.2 to 0.4 ppm residual at the first hydrant on the chlorine residual at these random areas. 3) Monitoring the results of random coliform samples also monitoring the chlorine residual at these random areas. 3. The addition of Sodium Hexametaphosphate has been approved and the Town has authorized CAMO Pollution Control, Inc. to install these' systems. CAMO Pollution Control, Inc. hopes to have these systems in full operation by February 1, 1986. Mr. Peter Marlow Dutchess County Health Department January 29, 1986 Page 3 CENTRAL WAPPINGERS WATER IMPROVEMENT AREA - HILLTOP WATER TREATMENT PLANT 1. To allow access to Hilltop well field by the Town Patrol, CAMO Pollution Control, Inc. has not installed any sort of barrier at the entrance to to the plant. It is our belief that the Town Patrol should have free access to all grounds at the Hilltop site. 2. Since the Ross valve mentioned in your letter is still used as a high pressure blow-off, it is advisable that this not be removed from the system to allow for a safeguard for overpressurization. 3. CAMO Pollution Control, Inc. monitors the chlorine residual at the well house, the first hydrant .on the system and at the random sampling points where colidorms are taken. We believe "that until such time as a chlorine contact tank can be installed, the disinfection process is being adequately maintained. No problem exists at the present time with failures of our coliform samples. 4. The Town has authorized CAMO Pollution Control, Inc. to install the Sodium Hexametaphosphate system. CAMO Pollution Control, Inc. hopes to have this system in full operation by February 1, 1986. I hope this letter has been helpful in bringing you up-to-date on the status of the Towns Water Treatment Facilities. If you have any questions, please do not hesitate to contact me.
