Abstract:
The Public Water Supply (PWS) datalayer (layer at MassGIS is named PWS_DEP) contains the locations of public community surface and groundwater supply sources and public non-community supply sources as defined in 310 Code of Massachusetts Regulations (CMR) 22.00. The public water supply systems represented in this datalayer are based primarily on information in the DEP’s Water Quality Testing System (WQTS) database. The WQTS database is the Department’s central database for tracking water supply data. The PWS datalayer also contains the locations of proposed wells that have a defined DEP approved wellhead protection area (Zone IIs). Proposed sources are not currently tracked in WQTS. |

Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.

Data consistent within project area
In September 2002 a new TYPE code ESW (Emergency Surface Water) was assigned to 65 surface water intake records to differentiate them from active and inactive surface water (SW) intakes. According to DEP Drinking Water Program policy ESWs (although still considered public water supplies under 310 CMR 22.00) do not have surface water supply protection areas. In November 2002 6 sources were removed, 12 sources added, and 22 sources moved/refined. In March 2003 13 sources were added, 6 removed, and 60 locations refined. In April 2003 8 sources were added, 5 removed, and 38 modified.
