{ "currentVersion": 11.4, "cimVersion": "3.4.0", "serviceDescription": "The\naquifer risk map is being developed to fulfill requirements of SB-200 and is\nintended to help prioritize areas where domestic wells and state small water\nsystems may be accessing groundwater that does not meet primary drinking water\nstandards (maximum contaminant level or MCL). In accordance with SB-200, the\nrisk map is to be made available to the public and is to be updated annually starting\nJanuary 1, 2021. The Fund Expenditure Plan states the risk map will be used by\nWater Boards staff to help prioritize areas for available SAFER funding.<\/font><\/span>

This layer shows the locations of state small and public water systems, as well as domestic well density. The state small water system locations were\ncollected by the Rural Community Assistance Corporation. The locations are\napproximate and may not exactly represent well locations or service boundaries.\nThe domestic well density per square mile is based on well completion report\ndata from the Department of Water Resources Online\nSystem for Well Completion Reports<\/a>. This layer also contains the public\nwater system boundaries (available on theĀ State Water Board REST endpoint<\/a>) for\nreference.<\/p><\/div><\/div><\/div>", "mapName": "Drinking Water Users", "description": "", "copyrightText": "Created by Emily Houlihan (Emily.Houlihan@waterboards.ca.gov) and Dori Bellan (Dorian.Bellan@waterboards.ca.gov), geologists, GAMA Program.", "supportsDynamicLayers": true, "layers": [ { "id": 0, "name": "Small Water Systems (RCAC)", "parentLayerId": -1, "defaultVisibility": true, "subLayerIds": null, "minScale": 0, "maxScale": 0, "type": "Feature Layer", "geometryType": "esriGeometryPoint", "supportsDynamicLegends": true }, { "id": 1, "name": "Domestic Well Density (DWR OSWCR, Post 1970)", "parentLayerId": -1, "defaultVisibility": true, "subLayerIds": null, "minScale": 0, "maxScale": 0, "type": "Feature Layer", "geometryType": "esriGeometryPolygon", "supportsDynamicLegends": true }, { "id": 2, "name": "Public Water Systems", "parentLayerId": -1, "defaultVisibility": true, "subLayerIds": null, "minScale": 0, "maxScale": 0, "type": "Feature Layer", "geometryType": "esriGeometryPolygon", "supportsDynamicLegends": true } ], "tables": [], "spatialReference": { "wkid": 102100, "latestWkid": 3857, "xyTolerance": 0.001, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -20037700, "falseY": -30241100, "xyUnits": 10000, "falseZ": -100000, "zUnits": 10000, "falseM": -100000, "mUnits": 10000 }, "singleFusedMapCache": false, "initialExtent": { "xmin": -1.393208931516077E7, "ymin": 4273303.998593987, "xmax": -1.2440711549409851E7, "ymax": 4692640.045198767, "spatialReference": { "wkid": 102100, "latestWkid": 3857, "xyTolerance": 0.001, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -20037700, "falseY": -30241100, "xyUnits": 10000, "falseZ": -100000, "zUnits": 10000, "falseM": -100000, "mUnits": 10000 } }, "fullExtent": { "xmin": -1.3849212914200002E7, "ymin": 3833616.076399997, "xmax": -1.270505742E7, "ymax": 5208347.065445091, "spatialReference": { "wkid": 102100, "latestWkid": 3857, "xyTolerance": 0.001, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -20037700, "falseY": -30241100, "xyUnits": 10000, "falseZ": -100000, "zUnits": 10000, "falseM": -100000, "mUnits": 10000 } }, "datesInUnknownTimezone": false, "minScale": 0, "maxScale": 0, "units": "esriMeters", "supportedImageFormatTypes": "PNG32,PNG24,PNG,JPG,DIB,TIFF,EMF,PS,PDF,GIF,SVG,SVGZ,BMP", "documentInfo": { "Title": "Map", "Author": "", "Comments": "", "Subject": "", "Category": "", "Version": "2.5.0", "AntialiasingMode": "Fast", "TextAntialiasingMode": "Force", "Keywords": "SB200,SWRCB,GAMA,groundwater" }, "supportsQueryDomains": true, "capabilities": "Map,Query,Data", "supportedQueryFormats": "JSON, geoJSON, PBF", "exportTilesAllowed": false, "referenceScale": 0.0, "datumTransformations": [ { "geoTransforms": [ { "wkid": 108190, "latestWkid": 108190, "transformForward": false, "name": "WGS_1984_(ITRF00)_To_NAD_1983" } ] }, { "geoTransforms": [ { "wkid": 108190, "latestWkid": 108190, "transformForward": true, "name": "WGS_1984_(ITRF00)_To_NAD_1983" } ] } ], "supportsDatumTransformation": true, "archivingInfo": {"supportsHistoricMoment": false}, "supportsClipping": true, "supportsSpatialFilter": true, "supportsTimeRelation": true, "supportsQueryDataElements": true, "mapUnits": {"uwkid": 9001}, "maxSelectionCount": 2000, "maxRecordCount": 160000, "maxImageHeight": 4096, "maxImageWidth": 4096, "supportedExtensions": "", "serviceItemId": "8fe76c1e9b91477b9bc702344649950d" }
