Name: Yearly Nitrate Concentration Averages in Public Supply Wells
Display Field: SITE_NAME
Type: Feature Layer
Geometry Type: esriGeometryPoint
Description: This feature class was created to facilitate mapping and geographic querying of Barnstable County water supply sources and their average nitrate concentrations from 2009-2012. This feature class contains those public water supply sources (wells and surface water sources) as defined in 310 CMR 22.00 located within Barnstable County (Cape Cod) of which nitrate concentration levels have been recorded. The nitrate concentration data has been compiled and added to this feature class by the Cape Cod Commission.

Description: The Cape Cod commission is using a combination of three GIS layers to inform us where potential areas of septic, cesspool, and Title 5 wastewater systems could be failing. The combination of these three layers could identify discrete areas where new wastewater systems could be employed to alleviate issues caused by poor septic systems. The first layer is called Board of Health Records. This layer was created from a consultant to the Commission who went to Town Halls and combed through paper records and deeds and collaborated with Town’s Boards of Health to create a database of all Title 5 systems that are reported as failed. These failed records were standardized and their addresses linked to parcel records and mapped. 10 of 15 towns participated in this exercise. The second layer is called Potential Title 5 Failures. This layer was created by the Cape Cod Commission GIS staff as a geospatial analysis. All non-sewered parcels on Cape Cod were queried for whether the size of the lot was smaller than 10,000 square feet; the water use was 1000 gallons per day or more; the depth to groundwater was less than 10 feet; and the lot was situated on clayey soils. If all four of these criteria were met, the parcel was flagged as a location where there was the possibility of a higher rate of septic failure to occur.The third layer is called Title 5 Loan Application. This layer was created from collaboration with the Barnstable County Department of Health. A list of addresses that filed for a loan with the County to repair or replace their Title 5 system was received. These addresses were linked to parcel records and mapped.

Description: This geodatabase intends to represent the state of water quality of the ponds and lakes within Barnstable County (Cape Cod), Commonwealth of Massachusetts, United States of America. Ponds and lakes studied as part of the Cape Cod Pond and Lake Stewardship Project (PALS) were classified by the Cape Cod Groundwater Guardian Team led by citizen groups and a variety of organizations including the Cape Cod Commission. The data was compiled in the early 2000s.
