The WIMS determinand is “Solids, Suspended at 105 C” (WIMS determinand code 0135), unit: mg/L. The extreme range of factors influencing SS and variability in time makes it difficult to derive standards that can be used helpfully and generally in the classification of water bodies. In most situations, a total suspended solids concentration below 20 mg/L appears clear, while levels over 40 mg/L may begin to appear cloudy. An annual mean of 25 mg/l of suspended solids is used as the Guideline Standard by environment agencies to help set controls on more or less continuous discharges of suspended solids to waters. The available data are extracted for the area of ‘Hertfordshire and North London’ and ‘Kent and South London’. Newly published data are incorporated into the WQE as they become available. Data from all freshwater river sample points collected for the purpose of “environmental monitoring statutory (EU directives)” (purpose code “MS”) with monitoring of selected determinands (substances) were used in the analysis. https://hosted-metadata-uat.bgs.ac.uk/geonetwork/srv/api/records/36f64661-ceb7-4193-8d03-bf6cbbf5e706/attachments/SuspendedSolids.PNG SuspendedSolids.PNG Suspended Solids Physico-Chemical Water Quality GEMET - INSPIRE themes, version 1.0 2008-06-01 geonetwork.thesaurus.external.theme.httpinspireeceuropaeutheme-theme no limitations no conditions apply 51609406-a465-44b2-bb9e-1599b47ec872 English http://data.os.uk/id/country/england -1.5651 1.8175 50.8582 52.1797 2015-01-01 2020-12-31 https://mapapps2.bgs.ac.uk/waterdataexplorer/index.html?extent=412721.7135%2C116256.8393%2C666722.2215%2C240214.3789%2C27700&showLayers=18930756177-layer-78%3BOS_Boundaryline_7486%3Bwms_668_LC.LandCoverSurfaces%3Bwms_9158_LC.25m.GB%3Bwms_7301_LC.25m.GB%3B1892f720b4b-layer-63_1 WWW:LINK-1.0-http--samples Water Data Explorer Web GIS Layer viewed in the Water Data Explorer Web GIS Commission Regulation (EU) No 1089/2010 of 23 November 2010 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards interoperability of spatial data sets and services 2010-12-08 false
