TECHNICAL REPORT NO. FWS/92/003

SUMMARY

River water quality is monitored in 32 catchments in the region. Samples are collected at a minimum frequency of once a month from 418 watercourses at 878 locations. Each sample is analysed for a range of chemical and physical determinands.

These sample results are stored in the Water Quality Archive. A computerised system assigns a quality class to each monitoring location and associated upstream river reach. The 1991 Classification has been assessed using sample results collected between 1 January 1989 and 31 December 1991.

The individual quality class determined for each reach is presented in a schedule format for each of the 32 catchments.

The regional classification of river water quality in 1991 is summarised as follows:

Quality Quality River Reaches Class Description km % of total

1A good quality 609.8 15-0 IB lesser good quality 1530.8 37.5 2 fair quality 1109.1 27.2 3 poor quality 786.6 19.3 4 bad quality 41.6 1.0

4077.9km 100.0%

The 1991 Classification represents an improvement in water quality from 1990. Increases were recorded in Class 1 "good quality" waters and decreases in Class 2 "fair quality" and Class 4 "bad quality". A slight increase in Class 3 poor quality was recorded. Overall 43.7% of the monitored network complied with their assigned river quality objectives (RQO).

Many catchments continue to show a low level of compliance which remains a significant regional challenge. However, a number of catchments have shown an encouraging improvement in 1991.

The 1991 Classification includes data obtained during the two drought years of 1989 and 1990 and this continues to contribute to the generally low level of compliance.

The principal causes of non-compliance in the region are high BOD, and ammonia concentrations and low dissolved oxygen concentrations which are all indicative of organic pollution. Farming activities are a major source of this pollution in the region. Historic mining activities particularly in Cornwall are also a significant contributor to non-compliance.

The deployment of special Task Forces to enforce pollution control legislation in areas where compliance with RQO's is poor should help to improve water quality. Special investigations of known discharges into non-compliant reaches will be carried out in accordance with a priority rating system. Other investigations will be carried out to identify and where possible resolve the causes of non-compliance, that will assist the direction of the Task Forces.

1. INTRODUCTION

River water quality is monitored in 32 catchments in the region. Samples are collected at a minimum frequency of once a month from 418 watercourses at 878 locations within the Regional Monitoring Network. Each sample is analysed for a range of chemical and physical determinands.

These sample results are stored in the Water Quality Archive. A computerised system assigns a quality class to each monitoring location and associated upstream river reach.

This report contains the results of the 1991 river water quality classifications for each of the monitored reaches and allows comparison of the 1991 classes with those determined from 1985 to 1990.

2. RIVER WATER QUALITY ASSESSMENT

The assessment of river water quality is by comparison of current water quality against River Quality Objectives (RQO's) which have been set for many river lengths in the region.

The RQOr s for the river lengths in the Regional Monitoring Network were assigned for most lengths in 1978. The RQO's were determined using the National Water Council's (NWC) River Classification System, (1), which identifies river water quality as being one of five classes as shown in Table 1 below:

TABLE 1

NATIONAL WATER COUNCIL - CLASSIFICATION SYSTEM

CLASS DESCRIPTION

1A Good quality

IB Lesser good quality

2 Fair quality

3 Poor quality

4 Bad quality

Using the NWC System, the classification of river water quality is determined by examining key determinands from the sample results at each monitoring location for a given time period. The values of these key determinands are compared as appropriate with the relevant criteria for each RQO.

1 The principal Key determinands are ammonia, biochemical oxygen demand (BOD) and dissolved oxygen. The NWC system also allows for the use of additional key determinands recommended by the European Inland Fisheries Advisory Commission (EIFAC) and by the European Commission on the Directive concerning the quality of surface water intended for abstraction of drinking water (75/440/EEC).

Regional climate and river flow characteristics, geology, associated historic mining activities and related contaminated land, soil and vegetation, land use practices and topography required the incorporation into the classification system of the following additional determinands: temperature, copper, zinc, pH, non-ionised ammonia and suspended solids. Details of the application of these key determinands and associated classification criteria are included in Appendix 8.1

The quality of river water is assessed annually using a composite of three years data. The 1991 Classification has been assessed using sample results collected between 1 January 1989 and 31 December 1991.

3. 1991 MONITORING PROGRAMME

Following the 1990 River Quality Survey undertaken by the NRA on behalf of the Department of the Environment, (2), the region's river monitoring programme was reviewed. Certain monitoring locations identified in Appendix 8.2 were deleted from the Monitoring Network. An additional 22 monitoring locations (either new or relocated), resulting in an additional 38.75 kilometres of river reaches, were added to the Network as identified in Appendix 8.3.

A minimum frequency of one sample per month was planned for all 878 monitoring locations. For certain locations, an increased frequency was planned dependant on additional regional and national requi rements.

A basic analytical suite of chemical and physical determinands was planned for each sample collected (see Appendix 8.4). At certain locations, additional determinands would be analysed according to regional and national requirements. The 1991 programme was planned to achieve 10922 samples.

The 1991 programme, as well as providing data for river quality classification, also incorporates the following national monitoring requirements of the United Kingdom (UK) government:

i) EC Freshwater Fish Directive ii) EC Dangerous Substances Directive iii) EC Surface Abstraction Directive iv) EC Exchange of Information Decision v) WHO Global Environmental Monitoring System (GEMS) vi) DoE Harmonised Monitoring Scheme

Data are transferred from the regional Water Quality Archive relating to these monitoring requirements and are reported separately by the UK government and European Commission (EC).

2 4. 1991 RIVER QUALITY ASSESSMENT

4.1 Regional Classification

Sufficient samples were collected from the Regional Monitoring Network to ensure that a quality class could be determined for all 878 monitoring locations and associated river reaches totalling 4077.9 kilometres.

The individual quality class assigned to each river reach is presented in a schedule format in Appendix 8.5 on a catchment basis. A summary of the overall regional classification is presented in Figure 1 below:

Figure 1 RIVER WATER QUALITY 1991 REGIONAL CLASSIFICATION

Class 1A 609.8 km 15.0%

Class 4 41.6 km 1.0%

Class 1109.1 km 786.6 km 27.2% 19.3%

3 For the DoE 1990 River Quality Survey, all river reaches were re­ measured. A national protocol on river reaches was adopted and this resulted in reaches entering enclosed waters (lakes and reservoirs) not being regarded as part of a linked river system unless a monitoring location was allocated at the riverine inflow to the enclosed water and within the enclosed water as well.

For some locations in the schedules in Appendix 8.5, an unmonitored stretch is indicated by 'Ur and relates to the use of this new protocol. Monitoring locations are being identified for these river reaches and enclosed waters. Sampling will commence during 1992. This will result in a quality class being determined for these river reaches and enclosed waters in future years.

4.2 comparison of 1991 Classes with 1990 Classes.

When river lengths common to both the 1990 and 1991 classification periods are compared, the total conqparable river lengths are 3988.6 kilometres (including common inferred reaches), (3).

The distribution of these river lengths in each quality class is shown in Figure 2 below:

0 Class 1A Class 1B Class 2 Class 3 Class 4 El 1990B 1991 The 1991 Classification indicates an increase in the total river lengths classed as 'Good quality', (Classes 1A and IB) and a reduction in the river lengths classed as 'Fair quality', (Class 2), and as 'Bad quality', (Class 4). A slight increase in river lengths of 'Poor Quality', (Class 3) was recorded.

The changes in river length between quality classes from the 1990 Classification to the 1991 Classification are indicated in Table 2 below:

TABLE 2 CHANGES IN RIVER LENGTH FROM 1990 TO 1991

Class 1990 Length Length downgraded to Length Unchanged 1A IB 2 3 4

No change in quality class has occurred over 2618 km (65.6%) of the Monitored Network between the 1990 and 1991 classification periods. There has been a downgrading in quality class for 584 km (14.6%) of the Network and an upgrading in quality class of 797 km (19.8%) between the two classification periods.

This variation in quality class, whilst indicative of quality change, can also be attributed to the sampling frequency and use of the quality assessment techniques, (4). The recorded change indicates that 1114 km (80.1%) of the river lengths that changed class moved into an adjacent quality class.

4.3 Quality Compliance with River Quality Objectives

The 1991 quality class for each river reach is compared with the RQO set for that reach as a measure of quality consistency and fitness for use. The overall regional compliance with RQO's is summarised in Figure 3. The information presented in Figure 3 relates to the complete 1991 Classification and is not directly comparable with that reported for 1990 because of changes in the monitoring programme since 1990, as reported in Section 3.

Class 1A Class 1B Class 2 Class 3 Class 4 ^ iggi ^^C/ass 1A Class 1B Class 2 Class 3 Class 4 Compliance with assigned RQO's was achieved in 1781.8 km (43.7%) of the Monitored Network; non-compliance with assigned RQO's was recorded in 2296.1 (56.3%) of the Monitored Network. However, 1293 km (56.3%) of the non-compliant river reaches failed to comply with the assigned RQO by only one class.

The compliance of individual river reaches with their relevant RQO's on a catchment basis is presented in Appendices 8.6 and 8.7.

Data used in the 1991 Classification includes data collected during drought periods of 1989 and 1990. Shese data contribute to the generally low level of compliance in the region. It should be noted that suspended solids criteria are operated on a fitness for use basis. As such, relatively small changes in annual mean concentrations can demote a river stretch to Class 3 or promote it to Class 1A. The primary cause of non-compliance in the region was failure to meet BOD criteria. Low dissolved oxygen and high total ammonia were also major contributors to non-compliance. This indicates the principal cause of water quality problems is organic pollution which is thought to largely arise from land use practices.

Non-compliance with copper criteria was a significant contributor to overall non-compliance and is due to mineralogical sources. However, it should be noted that compliance was tested against total copper results whereas the standards are for dissolved copper. This is due to historic constraints on analytical resources. Dissolved copper is currently being monitored at relevant sites, but as yet the database is not adequate to test compliance. Testing against total copper criteria is likely to result in an over-estimate of non-compliance.

Many catchments continue to show a low level of compliance with RQO's. Some notable improvements in compliance were recorded in the Rivers, Axe, Culm, Lemon, Harbourne, Kensey, Claw, Deer, E Looe, Gannel, Strat, Duntz, Mere and Yeo (Barnstaple). Deteriorations in compliance were recorded in the Rivers Lim, Teign, Yealm, Meavy, Thrushel and the Yeo (Bideford).

The percentage of non-compliance by determinand is shown below in Figure 4. Figure 4 REASONS FOR NON-COMPLIANCE SOUTH WEST REGION 1991 4.4 Catchment Quality Reports

The Annual River Water Quality Classification Report for 1991 will be supported by 34 catchment quality reports# which will contain details of the following: general Catchment Description, Catchment RQO Compliance, Catchment Classification and Determinand Statistics Relating to the Classification and initial diagnosis of the cause of problems. These will form part of the Catchment Action Plans.

5. REGIONAL QUALITY PERSPECTIVE

There has been a slight inqprovement in river quality over that reported in 1990 and 1989. Good quality - Class 1 was recorded in 52.5% of the monitored network in 1991 compared to 51% reported in 1990, (2).

The proportion of river lengths within Classes 2 and 4 has reduced substantially.

Compliance with RQO's has increased from 40% in 1990 (based on the re­ measured river reaches) to 43.7% in 1991. The majority of these RQO failures continue to be by only one NWC quality class, and even though compliance appears to be improving, the unacceptable low level of quality compliance remains a major regional concern. The improvement of river water quality is a regional priority.

The level of compliance with RQO's over the quality reporting periods of 1985 to 1991 is shown in Figure 5 below :

8 6. QUALITY IMPROVEMENTS AND PROSPECTS

Considerable effort is being made to sustain and enhance progress to achieve satisfactory water quality. Special recognition has to be given to the many farmers, companies and individuals who are clearly making a real effort to protect and improve our water environment. Yet despite the fact there are real signs of progress there is still much to do. The NRA has a number of initiatives to help foster sustained progress which include :

* Undertaking Catchment Action Planning.

* Deployment of staff in task teams to selected trouble spots to identify and bring under control pollution sources.

* Provision of guidance on how to minimise the risk of pollution including education and publicity initiatives.

* Close monitoring and enforcement and review of discharge consent conditions.

* Fair but firm administration of new farm storage regulations and pollution legislation.

In some cases this poor water quality results from historic mining activities and associated contaminated land which cannot be resolved in the short term. However, the work currently being carried out to resolve the water quality problems caused by the discharge of flooded mine water from the Wheal Jane mine may lead to the development of low cost solutions to these problems in the future.

RIVER LENGTH River distance in kilometres.

RIVER QUALITY OBJECTIVE The statement or category of water quality that a body of water should match, usually in order to be satisfactory for use as a fishery or water supply.

COMPLIANCE ASSESSMENT A procedure applied to the results of a monitoring programme to determine whether or not a water has met its agreed Quality standard.

QUALITY STANDARD A level of a substance or any calculated value of a measure of water quality, which must be met in order to protect a given use of a water body. The standard is expressed as a pairing of a specific concentration or level of a substance with summary statistics such as a percentile or maximum.

95 PERCENTILE STANDARD A maximum level of water quality, usually a concentration, which must be achieved for at least 95% of the time.

5 PERCENT Z1Z A minimum level of water quality, usually a concentration, which must be achieved for at least 95% of the time.

DISSOLVED The amount of oxygen dissolved in water. Oxygen is vital for life, so its measurement is important, but highly variable, test of the 'health' of a water, it is used to classify waters.

BIOLOGIC?-! ZSCijSN DEMAND These are measures of the amount of oxygen (ATU) consumed in water, usually by organic pollution.

The simple BOD value can be misleading because much more oxygen is taken up by ammonia in the test than in the natural water. This effect is suppressed by adding a chemical, Allylthiourea (ATTJ), to the sample of water taken for testing.

PH A scale of acid to alkali.

AMMONIA A chemical which is often found in water as a result of the discharge of sewage effluents. It is widely used to characterise water quality. High levels of ammonia adversely affect the quality of water for fisheries and abstractions for potable water supply. UNIONISED AMMONIA A fraction of ammonia poisonous to fish.

SUSPENDED SOLIDS Solids removed by filtration or centrifuge under specific conditions.

USER REFERENCE NUMBER Reference number allocated to a sampling point.

INFERRED STRETCH Segment of water which is not monitored and whose water quality classification is assigned from the monitored reach upstream.

UNMONITORED STRETCH Segment of water which is not monitored and for 'U' which it is considered in-appropriate to assign a water quality classification, from the upstream monitored reach, or where it is prior to an impoundment.

CLASS 'N' Insufficient sample's to calculate a water quality class.
