INTRODUCTIONKerala State Pollution Control Board with great pleasure is publishing the Water and Air Quality
Directory -2019, the 12th in its series, illustrating the status of water and air quality of our State. The water and Air quality data were generated by the laboratories of the Board during the year 2019 by monthly water quality monitoring and 24 hours Air quality monitoring. The data along with the location maps of various monitoring stations are presented in the directory. Details of monitoring conducted by the boardare shown below:-
1. National Water Quality Monitoring Programme (NWMP) : A total of 128 monitoring stations which include 65 stations in 42 Rivers, seven in Rivulets/ Tributaries, six in Reservoirs, Three in fresh water Lakes, eight in Estuarine lakes, Three in canals, Two in ponds and 34 station in Ground water under this programme.
2. State Water Quality Monitoring Programme (SWMP) at 129 stations in 22 rivers and 23 stations in 4 lakes.
3. National Ambient Air Quality Monitoring Programme (NAMP) at 27 stations in the state.
4. State Ambient Air Quality Monitoring (SAMP) at 8 stations in the state.
5. PM 2.5 monitoring commenced in all districts during 2019.
6. Monitoring Water Quality of Rural Water Supply Schemes.
7. Continuous Ambient Air Quality Monitoring Stations (CAAQMS) have been established one each at Thiruvananthapuram, Kollam, Kannur, Kozhikode and two stations at Ernakulam (one in commercial and one in industrial area).
The Designated Best Use (DBU) classification of the water bodies given in this directory is as per the Water Quality Criteria evolved by the CPCB. (Annexure IV). We express our sincere gratitude to the Central Pollution Control Board for their continuing co-operation and support, the Kerala State Remote sensing and Environment Centre for their valuable help for preparing the maps and the Board staff who collected samples, analyzed, consolidated and compiled the reports. Any suggestions and criticisms on how to improve the directory further would be entertained.As in the previous year, the trend analysis of Water Quality of major rivers and of Ambient Air Quality at the stations has also been presented incorporating the annual average data of 2019.We are proud to mention that the Board’s Central Laboratory at Gandhi Nagar, Cochin – 20 is an NABL accredited Laboratory as per ISO/IEC 17025:2017 by the National Accreditation Board for Testing and Calibration Laboratories for 61 parameters in the discipline of chemical and biological testing.

GENERAL EVALUATIoN oN WATER QUALITY
Rivers play major role in the water cycle of the blue planet and their quality is a direct reflection of the civilization and living standards of the region. Kerala is blessed with 44 rivers and their tributaries. All the rivers in our state are monsoon fed and water scarcity for drinking as well as for other uses are common in summer months at different places. Surface water quality of the water bodies are deteriorating due to various anthropogenic activities.The results of industrialization, urbanization, increased population etc. is felt on the water resources in such a way that the quantity is falling short and quality deteriorating with time. Waste disposal across the world primarily involves dilution by the water courses and various types of such anthropogenic activities constantly pollute the fresh water sources. Seasonal variations in precipitation and surface run off also affect the status of water quality.
Fresh, clean water is a limited resource and delivering clean water to the society is essential for a healthy ecosystem. The quality of water is identified in terms of the physical, chemical, biological and bacteriological parameters. With the ever increasing use of water for domestic, industrial and irrigation the monitoring and assessment of water quality on continual basis has become essential and it conveys the pollution status of a water body and the data generated can be utilized for planning and sustainable development. For identification of the water bodies or their parts where water quality is at variance with water quality criteria, it was felt important to measure quality of that water body or its parts. Central Pollution Control Board (CPCB) has established primary water quality criteria for classifying inland surface waters into various categories (A to E and Below E) based on Designated Best Use (DBU).
Classification of river stretches has been done based on the data generated during the year 2019. The major problem associated with river water quality is the bacterial contamination and 34% of the water bodies monitored under National Water Quality Monitoring Programme (NWMP) and State Water Quality Monitoring Programme (SWMP) are classified into various use based classes on the basis of bacterial population. Apart from the coli form counts, increased BOD, decreased Dissolved Oxygen content and increased Electrical Conductivity are also the major determining factors in the DBU classification.
Aruvippuram in River Neyyar is having average BOD value of 3.5 mg/L and classed into “D”. Munnattumukku and Thiruvallam in River Karamana are classed as “D” because of the low DO content and High BOD values along with increased bacterial population. The station at Pallathukadavu in Karamana River is also reported very low DO content. The sampling locations of Triveni, Kakiyar and Njunangar in River Pamba are having average coli form counts above 5000 MPN/100ml and fall into class “D”. Edatua and Tkakazhi are reported to have average DO content below 4 mg/L and are classed into “D” Naraparamba and Thavanur in River Bharathapuzha fall into “B” class because of the average BOD value. All other stations in Bharathapuzha are classed as “B” because of coli form counts. Kallayi River in Kozhikode district have low DO content, high coli form counts apart from high Electrical Conductivity. All stations in the rivers of Thodupuzha and Munnar are classed as “D” due to the increased coli form colonies. Kadambrayar in River Periyar is classified into “E” because of very low DO content and very high coli form counts. The station Manakkakadavu in Periyar River is reported to have DO average less than 4 mg/L and classed into “E”. Chitrapuzha at Irumbanam is also reported to have low DO content, High total coli forms and thus classed into “E”.
Ground water samples monitored during the year 2019 under NWMP and Source water monitoring of the Rural Water Supply Schemes across the state report the presence of coli form bacteria in 93.1% of the samples. Proximity to septic tanks, unprotected open wells, cluster of housing units and lack of periodical cleaning and disinfection are the reasons for increasing counts of coli forms in well water. Since majority of the people in the state depend on well water for drinking, the quality of well water has to be monitored periodically. Otherwise chances of spreading water borne diseases are more. Hence local administration and health authorities should make all efforts to ensure safe drinking water to the public.

11. AMBIENT AIR QUALITY DATA
The Kerala State Pollution Control Board is monitoring ambient air quality at 35 locations in the state. The locations fall under the categories of industrial, Commercial, residential and sensitive. Of the 35 stations 27 come under National Ambient Air Quality Monitoring Programme (NAMP) and 8 under State Ambient Air Quality Monitoring programme (SAMP). Sulphur dioxide, Nitrogen oxides and Respirable Suspended Particulate Matter (Class 10 micron size) (RSPM) are monitored regularly. 24 hour ambient air quality monitoring is conducted with a sampling frequency of two days/week. Sulphur dioxide (SO2) and Nitrogen Oxides (NOx) are monitored at four hour interval and Respirable Suspended Particulate Matter (RSPM) at eight hour interval. Monitoring of remaining parameters under NAAQS are in the implementation level. The Board had started PM 2.5 monitoring in all stations. The monitoring and method of analysis are according to the National Ambient Air Quality Standards (NAAQS). The details of ambient air monitoring stations with respect to location, category and data are provided in the ensuing pages.

Annexure IVWATER QuALITy CRITERIA (CPCB)
The water quality management in India is performed under the provisions of Water (Prevention and Control of Pollution) Act, 1974. But the Act does not define the level of wholesomeness to be maintained or restored in different water bodies of the country. It was considered ambitious to maintain or restore all natural water body at prestine level. Planning pollution control activities to attain such a goal is bound to be deterrent to developmental activities and is also cost prohibitive. Thus the Central Pollution Control Board evolved a concept of “Designated Best Use (DBU) to define the level of wholesomeness of the different water bodies to be maintained or restored according to the primary use of the water body.
