These are among the top three water pollutants nationally, degrading over 100,000 river and stream miles and over 3.5 million acres of lakes, reservoirs and ponds. About 6,000 nutrient-impaired waterbodies have been reported throughout the US. Most nutrient pollution comes from insufficiently controlled rain runoff or discharges from fertilizing lawns and croplands, municipal waste treatment systems, and animal wastes from livestock farming. Excess nitrogen or phosphorus can cause too much aquatic plant growth and algae blooms, sometimes choking off waterways and causing toxic or oxygen-poor conditions in which fish and other aquatic life often cannot survive. Nitrogen and phosphorus pollution can be harmful to human health if the affected waterway is used for swimming or if its contaminated water is consumed, and nitrates in drinking water have been linked to the fatal \u201cblue baby syndrome.\u201d These pollutants can also harm local economies through increased drinking water treatment costs, poor fish and shellfish harvests, less income from reduced recreational tourism, and reduced property values on polluted waterways.", "canModifyLayer": true, "supportedSpatialRelationships": [ "esriSpatialRelIntersects", "esriSpatialRelContains", "esriSpatialRelCrosses", "esriSpatialRelEnvelopeIntersects", "esriSpatialRelIndexIntersects", "esriSpatialRelOverlaps", "esriSpatialRelTouches", "esriSpatialRelWithin", "esriSpatialRelRelation" ], "geometryProperties": { "shapeLengthFieldName": "Shape_Length", "units": "esriDecimalDegrees", "mapUnits": {"uwkid": 9102} }, "standardMaxRecordCountNoGeometry": 32000, "indexes": [ { "name": "FDO_OBJECTID", "isUnique": true, "description": "", "fields": "OBJECTID", "isAscending": true }, { "name": "FDO_Shape", "isUnique": false, "description": "", "fields": "Shape", "isAscending": true } ], "htmlPopupType": "esriServerHTMLPopupTypeAsHTMLText", "supportsDatumTransformation": true, "minScale": 4622328, "supportsDynamicLegends": true, "hasAttachments": false, "advancedQueryCapabilities": { "supportsStatistics": true, "supportsSqlExpression": true, "supportsQueryWithResultType": true, "supportsTrueCurve": true, "supportsOrderBy": true, "supportsQueryRelatedPagination": true, "supportsSqlFormat": false, "useStandardizedQueries": true, "supportsLod": false, "supportsQueryWithDistance": true, "supportsQueryWithCacheHint": false, "supportsQueryWithDatumTransformation": true, "supportsCountDistinct": true, "supportsCurrentUserQueries": true, "supportsAdvancedQueryRelated": true, "supportsReturningQueryExtent": true, "supportsQueryWithLodSR": false, "supportsPagination": true, "supportsMaxRecordCountFactor": false, "supportsDistinct": true, "supportsTimeRelation": true, "supportsQueryAnalytic": false, "supportsPercentileStatistics": true, "supportsHavingClause": true }, "subtypeField": null, "supportsCoordinatesQuantization": true, "capabilities": "Map,Query,Data", "maxScale": 36112, "supportsExceedsLimitStatistics": true, "defaultVisibility": true, "hasMetadata": false, "tileMaxRecordCount": 4000, "typeIdField": null, "defaultSubtypeCode": null, "supportedQueryFormats": "JSON, geoJSON, PBF", "hasLabels": false, "drawingInfo": { "renderer": { "symbol": { "color": [ 132, 0, 168, 255 ], "width": 1.5, "style": "esriSLSSolid", "type": "esriSLS" }, "type": "simple" }, "scaleSymbols": true, "transparency": 0, "labelingInfo": null }, "geometryField": { "name": "Shape", "alias": "Shape", "type": "esriFieldTypeGeometry" }, "copyrightText": "", "geometryType": "esriGeometryPolyline" }
