7. Project Basics - Water Sources Some home owners make use of hand dug wells and cisterns Some home owners make use of hand dug wells and cisterns These sources seen as at a higher risk than drilled wells for potential contamination These sources seen as at a higher risk than drilled wells for potential contamination Reality is any on site well can be subject to contamination Reality is any on site well can be subject to contamination

8. Routes of Contamination Land spreading of manure and pesticides Land spreading of manure and pesticides Aging and failing septic systems Aging and failing septic systems Chemical spills, traffic accidents, railroad accidents Chemical spills, traffic accidents, railroad accidents Lack of maintenance Lack of maintenance

9. Leach Field Design Considerations Separation distances to wells, surface water bodies Separation distances to wells, surface water bodies Separation distances to bed rock or the water table Separation distances to bed rock or the water table Adequate length of trenches for proper treatment Adequate length of trenches for proper treatment

13. The Old Process

14. Requests for Inspections Sale of home, if required by lending agency Sale of home, if required by lending agency Complaint of water quality or failing septic system Complaint of water quality or failing septic system Illness or widespread contamination events Illness or widespread contamination events Construction of new septic systems Construction of new septic systems

15. Field Visit Conducted Inspector arrives on site and records observations and site specific data onto paper forms Inspector arrives on site and records observations and site specific data onto paper forms Identifies public health hazards and violations, recommends corrective procedures. Identifies public health hazards and violations, recommends corrective procedures.

18. Identified Inefficiencies Hand drawn sketches often lacking in detail Hand drawn sketches often lacking in detail Files stored in cabinets creating limited accessibility for studies or investigations Files stored in cabinets creating limited accessibility for studies or investigations –Response to contamination events requires digging through files for data, and some events full extent could be overlooked Inspector only generally carries one property's historical data to an inspection Inspector only generally carries one property's historical data to an inspection –Limits ability to detect neighborhood issues

19. The New Process

20. GIS used to automate the processing of data and storing that data in an easy to use form GIS used to automate the processing of data and storing that data in an easy to use form Inspectors given a laptop with the application installed and a Trimble GPS unit Inspectors given a laptop with the application installed and a Trimble GPS unit

21. Inspection Conducted Inspector loads up the application and finds the property location that they're inspecting Inspector loads up the application and finds the property location that they're inspecting Inspector fills out the forms for each component of the septic system and well Inspector fills out the forms for each component of the septic system and well

27. Measuring tool allows measurement of features, separation distances, areas of leach fields Measuring tool allows measurement of features, separation distances, areas of leach fields

28. Navigation tools allow for pan movement around the map, custom zoom, fixed zoom, and zoom to full extent of the map. Navigation tools allow for pan movement around the map, custom zoom, fixed zoom, and zoom to full extent of the map.

29. Zoom to GPS: Zooms map to current location of Trimble GPS unit. Removes need to manually search for your location on the map Zoom to GPS: Zooms map to current location of Trimble GPS unit. Removes need to manually search for your location on the map

30. Parcel tools allow for identification of map layer features, opening an inspection report, selecting/deselecting parcels on the map Parcel tools allow for identification of map layer features, opening an inspection report, selecting/deselecting parcels on the map

31. Opens the file linker for the selected parcel, allowing for the viewing of historical scanned documents Opens the file linker for the selected parcel, allowing for the viewing of historical scanned documents

32. Synch button synchs the laptop with the main database Synch button synchs the laptop with the main database

33. File Linking Historical paper records are being scanned into PDF documents Historical paper records are being scanned into PDF documents Gives the inspector the entire data base of information at their fingertips, dating back into the 1950's Gives the inspector the entire data base of information at their fingertips, dating back into the 1950's

35. Synchronization Each laptop is synched in the morning and at the end of the day Each laptop is synched in the morning and at the end of the day Ensures that each laptop has a complete data base when brought out into the field Ensures that each laptop has a complete data base when brought out into the field

Lamb Farms Concentrated Animal Feeding Operation located in Oakfield Concentrated Animal Feeding Operation located in Oakfield 2,400 Cows involved in the milking operation 2,400 Cows involved in the milking operation Producing 45 million gallons of manure per year Producing 45 million gallons of manure per year Stored in an on-site 15 million gallon lagoon and spread onto fields as fertilizer Stored in an on-site 15 million gallon lagoon and spread onto fields as fertilizer

42. Threat Identified Notified by NYDEC and USEPA of high levels of nitrates in wells serving the farm Notified by NYDEC and USEPA of high levels of nitrates in wells serving the farm Sampling in August of 2008 showed nitrate levels from 17 – 25 mg/l in the Farm's Wells Sampling in August of 2008 showed nitrate levels from 17 – 25 mg/l in the Farm's Wells

43. Public Health Response Farm notified and placed on increased monitoring as a public water supply Farm notified and placed on increased monitoring as a public water supply Sampling for coliform/E. Coli and Nitrate expanded to nearby residents to determine extent of contamination Sampling for coliform/E. Coli and Nitrate expanded to nearby residents to determine extent of contamination

46. Resolution Town of Oakfield applies and is awarded a grant to expand public water to the affected area Town of Oakfield applies and is awarded a grant to expand public water to the affected area Oakfield Water District #2 has been constructioned to serve the population nearby Lamb Farms Oakfield Water District #2 has been constructioned to serve the population nearby Lamb Farms
