        <SAMPLING_METHOD>Samples will be taken monthly. 
Sampling will be carried out using an integrated hose sample for all waters greater than 5 metres in depth. 
In waters of less than 5 metres depth, samples will be taken from just below the water surface, avoiding the surface film and without disturbing bottom sediments, using a simple sampling container.

http://intranet/ams_document_library/2007/001_050/006_07.doc

Phytoplankton and chlorophyll, samples will be taken from the same integrated hose sampler. 
For phytoplankton, the water sample must be transferred to a plastic bottle of at least 330ml and fixed with the addition of Lugols solution. 

The chlorophyll samples must be protected from warmth and light until filtration. Ideally filtration should be carried out immediately (and definitely within 4hrs of collecting the sample).

Every sample must have associated salinity and temperature data. Winter nutrient data are also required.</SAMPLING_METHOD>
        <ANALYSIS_METHOD>Phytoplankton

The sample will be settled and analysed following the Utermohl method.

All phytoplankton will be identified using the most up-to-date keys available.
Taxa will be based on the UK WfD taxon dictionary provided by the Environment Agency. Identification will be to species level where reasonably practicable or lowest taxonomic level.

Reference collection will be compiled and retained. This should consist of a slide or photographic collection containing examples of all taxa encountered.  The specimens should be fully labelled stating the identification given and from which sample the taxa originated.

Chlorophyll samples will be filtered and the volume filtered will be recorded and sent with the sample to the lab. The filters will be wrapped in aluminium foil and frozen to protect them until analysis. The laboratory will use acetone extraction and cell disruption

        <SAMPLING_METHOD>Species composition:
Samples collected monthly between June and September, at the same time and by the same method as for algal biomass determination. Preserved with Lugol's iodine to achieve a straw colour. Stored in a cool, dark place before processing.
Algal biomass (chlorophyll a):
Samples collected monthly throughout the year, from an appropriate point at the lake outflow, or from the lake shore or a suitable structure such as a jetty if access to the outflow is not possible. Representative open water samples are obtained by use of a “throw bottle” – a weighted bottle with a float, attached to a rope, which is thrown 5 -15m out from the shore to collect a sub-surface water sample from beyond the littoral zone.
Samples are stored at 5C in the dark, and filtered within 24 hours of collection prior to extraction with acetone and spectrophotometric analysis.
Bloom frequency:
Observation is made of the presence and severity of blue-green algal blooms on four occasions between July and October each year, using a standard recording sheet and photographs. Note: the method of assessment is still under development and amendments may be made.</SAMPLING_METHOD>

        <CATEGORY>CW</CATEGORY>
        <SAMPLING_METHOD>The macro-algae programme has 3 components:

1. Rocky shore macroalgae
Rocky shores will be searched every 2 a years in summer to compare the macroalgae taxa diversity against a check-list of approximately 100 species. The surveyor will also record a shore description, including the dominant shore types, sub-habitats and dominant species, on a standardised form so that shores can be scored and compared.

2. Opportunistic green macroalgae
(Littoral macroalgae blooms of opportunist algae including species of Enteromorpha, Ulva, Chaetomorpha, Pilayella, Ectocarpus and Porphyra.) 
Monitoring will be carried out once per year in the summer (June – August / September). 
The macroalgae bloom will be mapped to include the dimensions of the external perimeter of the bed (where cover &gt;5%) by walking the boundary and using differential Global Positioning System (DGPS). 
Pre-defined representative transect lines (minimum of 2) will be established prior to survey, based on a preliminary survey or remote imaging. A minimum of 5 ¼ m2 quadrats will be spaced along each transect.
The size of opportunist algal mats and the density of weed cover and its entrainment within the sediment, within each quadrat will be estimated. 
Where access to the bed is not possible, photographs of the affected area will be taken and linked to the aerial photographs or remote images as an alternative.

3. Fucoid extent
The most upstream limit of Fucus ceranoides, F. vesiculosus and F. spiralis in transitional waters will be determined by surveying the inter-tidal zones at low water. Measurements, models or historical data will be used to determine the salinity range at this location.</SAMPLING_METHOD>
        <ANALYSIS_METHOD>1. Rocky shore macroalgae
Taxa will either be recorded in the field or taken back to the lab to identify. The taxa data will be analysed to calculate proportions of :
-red and green species 
-opportunist species 
-ecological status groups (e.g. perennials / annuals)
Species richness and composition attributes will be compared with reference data.

2. Opportunistic macroalgae
Percentage Cover
The total cover within each quadrat to the nearest 5% will be estimated and recorded in the field. The main taxa present and their dominance, e.g. Enteromorpha sp, Ulva sp, Chaetomorpha sp, Porphyra sp, Pilayella sp, Ectocarpus sp. will also be recorded.
 
Entrainment of algae in sediment
Some algae may be covered in silt and be growing at depth within the sediment.  This growth of entrained algae, and the depth to which it extends, should be recorded if possible.

Biomass
Algae for biomass samples will be removed from the quadrat using scissors, trimmed to sediment surface only. Algae will not be removed from within the sediment. Biomass will be determined by wet weighing. 

3. Fucoid extent
Species will be identified and recorded in the field and the position will be recorded in the field using GPS.</ANALYSIS_METHOD>
        <STANDARDS>Oppertunistic Macroalgae: The method used should conform to international standard EN 14996 Water Quality - Guidance on assuring the quality of biological and ecological assessments in the aquatic environment.

        <CATEGORY>CW</CATEGORY>
        <SAMPLING_METHOD>The angiosperm programme has 2 components:

1. Seagrass
Sampling will be undertaken annually during the summer months. 
A littoral seagrass bed’s area will be mapped and a series of transects conducted for noting species and estimating percentage cover.
The perimeter of the continuous bed (&gt;5% cover) will be mapped by walking the boundary and using differential Global Positioning System (DGPS) or from remote sensed images that have been ground-truthed. 
A sampling grid will be designed prior to the survey. Available information on the location and extent of beds from remotely surveyed information or a preliminary site visit will be used to plan the shape and size of the grid of sampling points and the distance between points that will satisfactorily quantify shoot density. 
The % cover of each seagrass species within the quadrats will be estimated whilst in the field or from digital photographs and recorded on a standardised survey form, along with general details about the site.
Subtidal seagrass will not be monitored until a method that does not require the use of divers has been developed and agreed.
2. Saltmarsh
Aerial surveys will be undertaken to provide maps of saltmarsh extent. 
Ground truth surveys will be undertaken to confirm saltmarsh extent, assess the species diversity of the saltmarsh and confirm location of saltmarsh zones. The surveys will be undertaken at low water. The field survey methodology is still being tested and the classification metric is still under development.</SAMPLING_METHOD>
        <ANALYSIS_METHOD>1. Seagrass
Species will be identified, and the percent cover estimated in the field. 
Quantitative comparisons of (1) taxonomic composition, (2) bed extent and, (3) bed density will be made with previous years’ data.
A 5 year running mean of density will be calculated once sufficient surveys have been carried out.

2. Saltmarsh
Species will be identified in the field. Overall saltmarsh extent and the location of zones will be digitally mapped using GIS. 
Percentage deviation of saltmarsh extent and zone sizes and presence from baseline values will be calculated each year. Once sufficient surveys have been carried out the deviation over a running 5 year period will be calculated.</ANALYSIS_METHOD>

        <CATEGORY>LW</CATEGORY>
        <SAMPLING_METHOD>The method involves recording macrophyte species present in 3 different ways:Perimeter survey – along 100m stretch of shore, presence of plant material on the strand line, and emergent/marginal/amphibious species present between current water level and high water mark.Shore survey – along 100m stretch of shore, species recorded at 4 depths (0.25, 0.50, 0.75 and &gt;0.75m) at five points by wading out and use of rake/grapnel and/or underwater viewerBoat survey – at mid-point of the shoreline survey stretch, transect perpendicular to the shore, from shore to maximum depth of colonisation, species present recorded at 10 equally spaced points along the transect.In addition to species presence, an overall biomass rating and assessment of filamentous algae is recorded at each point. Substrate, and transparency (Secchi depth) are also recorded.</SAMPLING_METHOD>
        <ANALYSIS_METHOD>The analysis is based on a Lake Macrophyte Nutrient Index (LMNI) which awards values to species of submerged or floating leaved macrophytes. These values are based on an extensive dataset consisting of most of the recorded data for UK lake surveys.  This, together with a set of environmental variables, is then used to calculate an EQR based on the plant’s response to nutrients. Survey data is accorded a weighted value that varies depending on the distribution of macrophytes in each water-body.  Percentage cover for each species recorded is a mean of these values, and is used to calculate % cover EQR.  EQRs for relative cover of filamentous algae, invasive alien species and number of functional groups are also calculated.  Classification is based on the mean of the lowest two of these EQR values for each water-body.</ANALYSIS_METHOD>

        <CATEGORY>RW</CATEGORY>
        <SAMPLING_METHOD>Surveys are carried out using the standard method adopted by the Environment Agency for the assessment of the trophic status of rivers. The method is also for the designation of Sensitive Areas (Eutrophic) (SA(E)) under the requirements of the EC Urban Waste Water Treatment Directive (UWWTD, 91/271/EEC) and to aid in the determination of ecological status in the context of the EC Water Framework Directive(WFD, 2000/60EC).

The method represents best current practice.  This method is currently being adapted to fulfil the needs of the Water Framework Directive (WFD), however the sampling methodology will remain fundamentally unchanged.  Only the number of species and the scoring system will be amended.

The macrophyte flora and physical character of defined lengths (100m) of watercourse are surveyed.  The presence, absence and % area covered by each macrophyte species are recorded and used to calculate either the WFD nutrient index or MTR score.  All species in the defined survey stretch are recorded as well as a set of physical parameters that aid data interpretation.  The location of survey sites varies according to the purpose of the survey. Less impacted ‘control’ sites may be used to help determine point source eutrophication impact.

The survey samples macrophytes (plants identifiable with the naked eye), in rivers and streams. The survey is not suitable for standing waters, canals or tidal rivers.</SAMPLING_METHOD>
        <ANALYSIS_METHOD>The survey is based upon the spectrum of tolerances to nutrient enrichment, which can be expressed by assigning scores to species on a scale of 1 to 10.

In both the River Macrophyte Nutrient Index (RMNI) for WFD and the Species Trophic Rank (STR) for the Mean Trophic Rank (MTR) method lower scores indicate lower tolerance of nutrient enrichment. Survey data is in the form of qualitative (presence/absence) and semi-quantitative (estimates of % cover) records of macrophytes and physical characteristics.</ANALYSIS_METHOD>

        <SAMPLING_METHOD>The method involves collecting epilithic or epiphytic diatoms from representative (at least 10 m strip) of littoral lake habitat. Samples are collected from cobbles where these are the dominant littoral substratum. If cobbles or small boulders are absent or the bed is dominated by fine sediments with only a few large stones, collect  samples from submerged stems of emergent plants such as Phragmites australis, Sparganium erectum, Glyceria maxima or Typha spp. Phragmites australis is widespread in UK standing waters and should be used wherever possible. Phytobenthos material is removed from the substratum using a tooth brush and small amounts of water.

Summary:
Choose a site at least 10m long with a riffle-run-pool sequence or run and glide. Collect samples in spring and autumn from at least 5 cobbles or small boulders that are permanently submerged and reachable with thigh waders. If cobbles are not available, use methods for man-made structures (C) or emergent macrophytes (D) or submerged macrophytes (E).

Sample collection:
Cobbles without significant filamentous algae
Remove loosely attached surface contamination, place stones in a tray with ~50ml of river water. Rinse a toothbrush with river water and brush the upper surface of the stone to remove the diatom film, regularly rinsing the toothbrush in the tray to remove the diatoms. Repeat with the other stones. Transfer the tray water into the sample bottle.
Cobbles with abundant filamentous algae 
Choose between 1-5 cobbles or small boulders depending on % algae cover and remove from the water. Wash the cobble and brush the upper surface of it (inc fil algae) with a toothbrush to remove the diatoms. Wash in tray water. Remove any filaments not dislodged and place in the sample pot.	
C
Dislodge diatom film from the vertical surface to 30cm deep, into a net and bottle at 5 different places.
D
Collect samples from the submerged part of 5 different healthy plants of the same emergent macrophyte species. Ensure each is ~5 cm in length, with the lower end from ~ 20cm deep. Cut away excess stem then place a sampling bottle upside down over the underwater stem. Cut the stem, then turn the bottle plus stem upright. Brush diatoms from the stem into the bottle. Record plant species used.
E
Collect 5 samples from 5 different plants of same species/genus. Record species/genus used. Place stem and branches in bag with 50ml of river water and shake. Pour the brown suspension into a bottle and preserve.

Preserve all samples with Lugol's iodine to achieve a straw colour. Store in a cool, dark place before processing.</SAMPLING_METHOD>
        <ANALYSIS_METHOD>Algae are scraped from the substrate. The resulting suspension is collected in a plastic bottle, fixed with Lugol’s iodine and stored prior to analysis.   Samples are either digested in a saturated solution of potassium permanganate and concentrated hydrochloric acid, or digested with hydrogen peroxide in order to remove organic material, and permanent slides are prepared using Naphrax as a mountant.
	
Valves of non-planktonic taxa are identified and counted using 1000 ? magnification. By establishing site-specific reference conditions the relative ecological status of any sample can be quantified by relating the number and composition of valves to an optimum state. A standard taxon dictionary is used. The deviation from optimum state can be correlated with an increase in nutrients. The UK ‘Trophic Diatom Index (TDI)’ method is used.</ANALYSIS_METHOD>

Samples will be taken once per annum, in early Spring [1st Feb to 30th April]. The monitoring cycle is once every 3 years. 
Sub-tidal samples will be collected by boat. The standard sampling gear is 0.1m2 Day Grab. 
Intertidal samples will be taken by hand corer. There are 2 standard sizes – 0.01m2 and 0.1m2. Detailed instructions at http://intranet/ams_document_library/2007/001_050/009_07.doc)

Benthic invertebrate sampling is stratified according to EUNIS habitat type. Samples will be taken from matched stable, depositional habitats so that the variability in the biological communities from a defined EUNIS habitat from different geographical locations and water body types can be compared. Samples will be spread as widely as possible throughout the habitat in the water body, but outside of any ‘allowable zones of effect’.

Imposex assessment
Samples will be taken once per annum during the sampling season (June to September). The monitoring cycle is expected to be every 4 years. 40 specimens are required per sampling station. Hand collect at low tide, between spring low water and mid tide levels.</SAMPLING_METHOD>
        <ANALYSIS_METHOD>Soft sediment macrobenthic community analysis
Samples will be sieved using a 0.5mm sieve mesh in transitional waters and 1mm mesh in coastal waters.

After sieving, samples will be fixed in 4-8% buffered formaldehyde for later laboratory analysis.

All specimens should be examined under suitable magnification and identified to the lowest taxonomic level possible and counted. 

Any fragmented specimens should only be counted if the head is present. Other partial specimens which can be identified may be recorded but should not be used in any subsequent data analysis.

Juveniles should be recorded separately as their numbers may introduce a seasonal bias to the data.

        <SAMPLING_METHOD>Chironomid Pupal Exuviae Technique (CPET)- With an extendable handnet, skim the surface of the water from the leeward bank or shore  (where the wind is blowing to) without entering the water. The net will fill with debris, including exuviae, as it is dragged through the water surface. If necessary, the debris can be regularly emptied into a bucket containing water from the same site.  In practice, sufficient pupal exuviae for the recommended method are likely to be obtained before the net is full of debris.Acid pressure lake macroinvertebrates. The methodology is a modification of sampling procedures implemented in the British Isles for the collection of river macro-invertebrates described in BT001 (Murray-Bligh, 1999a) and ISO 7828 (ISO, 1985). Many of the principles and procedures are the same but some have been altered significantly. The method is based on the collection of a single fixed duration sample from a station located in a stony area of shore and sampling is subdivided into active search and kick sampling the substratum.</SAMPLING_METHOD>
        <ANALYSIS_METHOD>CPET: Use sieves and washing to produce a debris free sample of exuviae, remove aliqots to a Petri dish with a tea strainer and while viewing the dish contents through a low-power binocular microscope, all chironomid pupal exuviae should be picked out from the dish with fine forceps and placed in 70% alcohol. It is necessary to pick out all chironomid pupal exuviae. Take small subsamples of around 50 pupal skins each time if possible and continue until 200 exuviae have been identified using the Freshwater Biological Association ‘Guide to the identification of chironomid pupal exuviae occurring in Britain and Ireland’.Acid pressure lake macroinvertebrates: Sample preserved in the field if possible and processed to mixed taxon level in the laboratory according to BT001.</ANALYSIS_METHOD>

        <CONFIDENCE>Confidence in classification for UK lake methods is determined by the VISCOUS model. This uses the standard deviation and mean of reference sites, the distance of an EQR to the class boundaries and the number of samples taken, to determine confidence of classification. CPET:will produce 95% confidence of class depending on distance from boundary. Lake Acidification tool: The maximum confidence of class achieved by LAMM at clear water lakes, at the mid point of Moderate is 84% (based on one sample)
The maximum confidence of class achieved by LAMM at humic water lakes, at the mid point of Moderate/Poor/Bad is 98% (based on one sample)

The approach to uncertainty assessment assumes that the estimated mean LAMM EQR is normally distributed with a standard deviation that is a modelled function of EQR. Using the estimated standard deviation and number of samples collected we determine the confidence that the observed mean EQR lies within particular class boundaries.  The approach follows that of Ellis (1990) (available at http://publications.environment-agency.gov.uk/epages/eapublications.storefront/4b100774024a67a6273fc0a802960648/Product/View/GEHO1006BLOR&amp;2DE&amp;2DE. In reporting the overall confidence of being worse than Good we use the weight of evidence derived from the status and confidence of each biological tool that is sensitive to the same pressure.</CONFIDENCE>

        <SAMPLING_METHOD>Standard RIVPACS sampling protocol.  At shallow sites, this comprises a 3-minute hand net sample collected from all habitats in the river in proportion to their cover, plus a manual search for one minute.  In deep waters, the hand-net sample is replaced by a similar sample collected by very long-handled net from the river bank, a small or medium naturalists dredge, or air lift sample.  Samples from deep waters are also supplemented by a 1-minute sweep of marginal habitats using a hand-net from the riverbank. The procedure is described in:

Possible deviation from FAME protocol in salmonid rivers (to reduce the likelihood of stress and subsequent fish loss), provided the shorter length sampled will still result in all species present being caught (with no bias to salmon over trout); will not result in less than 30 fish being caught; will ensure that all habitat components are included, e.g. riffle, run and pool; and the width and length of a site/sampled area is always measured.

In larger rivers, we intend to use a multi-method sampling strategy, including a combination of qualitative electric fishing (species and age composition), hydro-acoustics (abundance and size distribution) and angling catch.

        <SAMPLING_METHOD>This survey concerns the sampling of water chemistry in transitional and coastal waters. This procedure is the standard procedure adopted by the Environment Agency and is part of the National Sampling Procedures Manual.

Standards ISO 5667 Part 1 to 17 are followed. For the purposes of this procedure, the definitions given in ISO 6107 parts 1 and 2 apply. 

The procedure describes:
Pre-sampling quality checks	
Selecting sampling locations
Arrival on site	
Avoidance of contamination	 
Watercourse sampling 	 	 
Taking the sample	
Labelling	
Field measurements	 
Chains of audit	
Storage, transport and delivery of samples	
Storage at depots	
Maintenance of equipment	
Laboratory storage provision

The technical guidance for the above steps varies according to the purpose of data collection. Sampling can either be direct of indirect.
Direct sampling involves placing the sampling bottle under the surface of the water allowing it to fill. Indirect sampling involves lowering a water-sampling container below the surface of the water body and allowing it to fill. The contents are then used to fill up sample bottles that vary according to the required method of analysis, some may be treated with preservatives. 

Hand-held measuring devices are used to sample some water quality indicators such as salinity, pH and temperature. Such measurements must be made using the 'YSI 556 Multi-parameter Meter'.</SAMPLING_METHOD>
        <ANALYSIS_METHOD>Laboratory analysis of water samples using standard and UKAS accredited procedures for the analysis of water and associated materials.

At Surveillance sites the water sample is scanned for all Annex 10 (plus 8 &amp; 9) substances. The scan uses a range of methods including targeted-based multi-residue and ICPMS devices.

At Operational sites the water sample will be analysed for specific substances known to be present or discharged into the water body.</ANALYSIS_METHOD>
        <STANDARDS>ISO 5667 Part 1 Guidance on the design of sampling programmes. Procedures are UKAS Accredited</STANDARDS>
        <CONFIDENCE>Three-year data sets comprised of 36 samples are used to assess status and to check compliance with objectives. 36 samples derive 95% confidence at the 90%ile.</CONFIDENCE>
        <FREQ_METHOD>The competent authority (Environment Agency, England and Wales) has used a frequency of twelve samples per year (monthly) for over twenty years. Monthly sampling has been found adequate to assess seasonal variations and when combined into a three-year data set the programme delivers a confidence of 95%. A consistent monitoring frequency allows simple data comparison between water bodies, catchments and River Basin Districts.

For administrative purposes a fixed sampling frequency is most efficient and will simplify the management of monitoring programmes.</FREQ_METHOD>

        <SAMPLING_METHOD>This survey concerns the sampling of water chemistry in coastal waters. This procedure is the standard procedure adopted by the Environment Agency and is part of the National Sampling Procedures Manual.

Standards ISO 5667 Part 1 to 17 are followed. For the purposes of this procedure, the definitions given in ISO 6107 parts 1 and 2 apply.

The procedure describes:
Pre-sampling quality checks	
Selecting sampling locations
Arrival on site	
Avoidance of contamination	 
Watercourse sampling 	 	 
Taking the sample	
Labelling	
Field measurements	 
Chains of audit	
Storage, transport and delivery of samples	
Storage at depots	
Maintenance of equipment	
Laboratory storage provision

The technical guidance for the above steps varies according to the purpose of data collection. Sampling can either be direct of indirect.
Direct sampling involves wading into the water and placing the sampling bottle under the surface of the water allowing it to fill. Indirect sampling involves throwing a container, such as a can, into the water and allowing it to fill from the surface. The contents are then used to fill up sample bottles that vary according to the required method of analysis, some may be treated with preservatives. 


Hand-held measuring devices are used to sample some water quality indicators such as pH and temperature. Such measurements must be made using the 'YSI 556 Multi-parameter Meter'.</SAMPLING_METHOD>
        <ANALYSIS_METHOD>Laboratory analysis of water samples using standard and UKAS accredited procedures for the analysis of water and associated materials. Analysis is required for:

Dissolved oxygen (field), salinity – conductivity (field), temperature (field), transparency (field), cholorophyll-a biomass, total oxidised nitrogen, phosphate, silicate, ammonia, nitrate, nitrite, dissolved inorganic nitrogen.</ANALYSIS_METHOD>

Operational sites:Water bodies are selected for diatom monitoring if they are at risk of not meeting good status because of point-source or diffuse nutrient pressures. Monitoring is targeted at water bodies reported to be ‘at risk, but were more information is required (1b)’ and where the new phosphate standard is exceeded. All such water bodies are monitored where the pressure is from point-sources. Where the pressure is from diffuse sources, a proportion of water bodies have been selected. The selection represents water bodies of all typologies within each River Basin District. Each water body has been assigned a ‘grouping category’ so that the results can be linked to other un-monitored water bodies within the River Basin District.</SITE_METHOD>

Where sampling is from a bridge samples are taken at mid-channel except where site characteristics, such a proximity of discharge, determine otherwise.
A high proportion of bankside samples is taken in most Regions.  Particular care is taken to ensure that representative samples are obtained in these circumstances.  Samples are taken away from pools or stagnant zones and not less that 30 cm from the bottom to avoid disturbing sediment.

The programme makes best use of monitoring sites where samples are taken for other reasons, such as the Freshwater Fisheries Directive. These sites have already been established in accordance with the criteria above.

A model is used to estimate the flow at ungauged sites for both the natural reference flow and for scenario flows with different levels of artificial influences. The model is calibrated using a core set of good quality gauging stations. This approach is considered adequate for currently ungauged river waterbodies.

Surveillance: Use the existing benchmark sites within the NRFA (National River Flow Archive) network. These have been selected for their strategic importance, quality and length of record, they qualify as surveillance sites because of the strategic value in maintaining a long period of record.

Operational: All other permanent and current flow gauging stations not already included in the surveillance network. Ad hoc investigative monitoring using temporary structures or portable equipment.</SITE_METHOD>

              <CONFIDENCE>The uncertainty associated with open channel flow gauging structures varies according to the type of structure and local conditions. The typical range of uncertainty for all river flow gauges is between 5% and 20%.

For modelled natural flow 68% of the flow estimates will be within the margin of +/- 16% for mean flow, +/- 65% for Q95 and +/- 36% for Q70.</CONFIDENCE>

              <CONFIDENCE>Confidence in classification for UK lake methods is determined by the VISCOUS model. This uses the standard deviation and mean of reference sites, the distance of an EQR to the class boundaries and the number of samples taken, to determine confidence of classification. CPET:will produce 95% confidence of class depending on distance from boundary. Lake Acidification tool: The maximum confidence of class achieved by LAMM at clear water lakes, at the mid point of Moderate is 84% (based on one sample)
The maximum confidence of class achieved by LAMM at humic water lakes, at the mid point of Moderate/Poor/Bad is 98% (based on one sample)

The approach to uncertainty assessment assumes that the estimated mean LAMM EQR is normally distributed with a standard deviation that is a modelled function of EQR. Using the estimated standard deviation and number of samples collected we determine the confidence that the observed mean EQR lies within particular class boundaries.  The approach follows that of Ellis (1990) (available at http://publications.environment-agency.gov.uk/epages/eapublications.storefront/4b100774024a67a6273fc0a802960648/Product/View/GEHO1006BLOR&amp;2DE&amp;2DE. In reporting the overall confidence of being worse than Good we use the weight of evidence derived from the status and confidence of each biological tool that is sensitive to the same pressure.</CONFIDENCE>

          <SITE_METHOD>Overview: Environmental standards for the regulation of the hydrological regime are generally based on flow statistics. A model is used to estimate the flow at ungauged sites for both the natural reference flow and for scenario flows with different levels of artificial influences. The model is calibrated using a core set of good quality gauging stations. This approach is considered adequate for currently ungauged transitional waterbodies.

Surveillance: Use modelled flow (model calibrated using a subset of the rivers surveillance network)

Operational: Use modelled flow (model calibrated using a subset of the rivers surveillance network) with ad hoc investigative monitoring based on risk assessment and subject to feasibility.</SITE_METHOD>

This sub quality element will be monitored in all surveillance water bodies that have fine sediment habitats. 

For operational purposes, benthic invertebrates will be monitored in a sub-set of water bodies at risk from water quality and morphological pressures such as organic enrichment and dredging. To increase efficiency, representative operational water bodies have been selected that coincide with Surveillance or existing National monitoring sites. 

Imposex assessment
This sub quality element will be monitored in water bodies that have rocky shore habitats and are at risk from TBT pressure.</SITE_METHOD>
          <SUBSITES_METHOD>Soft sediment macrobenthic community analysis
The whole water body is referred to as the ‘site’.  Multiple samples will be taken within each water body and these can be called ‘sub-sites’. 
The number of samples depends on the size of water body:
-15 samples will be taken in Transitional water bodies less than 400 ha and Coastal water bodies less than 4000 ha. 
-30 samples will be taken in Transitional water bodies between 400 and 2000 ha, and Coastal water bodies between 4000 and 20000 ha. 
-45 samples will be taken in Transitional water bodies greater than 2000 ha and Coastal water bodies greater than 20000 ha. 
Samples will be spread widely throughout the waterbody and will be targeted at specific habitat types. If a water body is being monitored for operational reasons, some replicates will be located around the pressure.</SUBSITES_METHOD>

For operational purposes, benthic invertebrates will be monitored in a sub-set of water bodies at risk from water quality and morphological pressures such as organic enrichment and dredging. To increase efficiency, representative operational water bodies have been selected that coincide with Surveillance or existing National monitoring sites.

The whole water body is referred to as the ‘site’.  Multiple samples will be taken within each water body and these can be called ‘sub-sites’. 
The number of samples depends on the size of water body:
-15 samples will be taken in Transitional water bodies less than 400 ha and Coastal water bodies less than 4000 ha. 
-30 samples will be taken in Transitional water bodies between 400 and 2000 ha, and Coastal water bodies between 4000 and 20000 ha. 
-45 samples will be taken in Transitional water bodies greater than 2000 ha and Coastal water bodies greater than 20000 ha. 
Samples will be spread widely throughout the waterbody and will be targeted at specific habitat types. If a water body is being monitored for operational reasons, some replicates will be located around the pressure.</SUBSITES_METHOD>
