USEPA and NEERI collaboration on Joint drinking water laboratory strengthening work: Preparation of Guidance Manual, (Year : 2018)
|
The project is one of the activities under drinking water safety through joint collaboration with USEPA and WHO. The main issues involved with drinking water safety are water quality management, surveillance and control mechanism. Currently there are many agencies involved in water supply in India and each agency has its own laboratory test practices. Efforts have been made to prepare a common laboratory guidance manual providing uniformity in laboratory techniques adopted by various laboratories and thus help to adhere to strict quality assurance practices. Considering the demand for a comprehensive manual by various water quality testing laboratories at Central, State, District, Block and Gram Panchayat levels, USEPA and WHO in collaboration with lead Ministries involved in the water management programme, has retained National Environmental Engineering Research Institute (NEERI) in May 2006. The main objective of the manual is to ensure quality control in the drinking water quality testing laboratories. The manual includes the methods for each physico-chemical and biological parameters, which can be adopted by all laboratories. The manual delineates the various aspects of organizational structure of laboratories, roles and responsibilities, staff management, and training. The basic setup of laboratory management and safety, required for drinking water quality testing, have been outlined. Two generally applicable methods for analyzing all the essential parameters for drinking water quality testing are described. The testing procedures of all the parameters monitored, as per Indian Standards for drinking water are presented in the manual. In addition, analytical methods for a few additional parameters required in typical situations like industrial pollution are also given. Meetings and workshops have been organized at NEERI, Nagpur and National Institute of Communicable Diseases (NICD), Delhi, during the compilation, and comments and suggestions offered by various experts associated in this area, have been suitably incorporated in the manual.

Assessment of Water Quality and Suggest Treatment Measures for Raw Water Source of MIDC Water Supply Scheme, (Year : 2018)
|
The MIDC water supply scheme, Hingna industrial area, Nagpur uses Ambazari lake water as a raw water source for their water treatment plant. The treated water is supplied to various industrial units and their residential colonies located at Hingna industrial area, Nagpur. Executive Engineers (E & M), MIDC Division, Hingna industrial area, Nagpur. vide letter No. EE (E&M)/NGP/230, dated February 22, 2005 informed that they have been experiencing presence of pungent odour and yellowish colour in the raw water at Ambazari lake since last few years. The water samples have been repeatedly tested at the public health laboratory, Nagpur but causes for pungent odour and yellowish colour could not be traced out. Even after taking many corrective measures in water treatment for ensuring good quality of water supply, it is not possible to completely eliminate the presence of pungent odour and yellowish colour in treated water. In view of this, Executive Engineer, MIDC Nagpur retained NEERI to identify the cause of problem and to suggest remedial measures to coup up with the nuisance of odour and colour development in the treated water at MIDC water supply scheme, Hingna industrial area Nagpur. Accordingly studies are undertaken to find out the causes and probable remedial measures for the above mentioned problem. Raw water samples at various depths of Ambazari lake and at various stages of treatment were collected and analysed for physico-chemical and biological parameters. Water analysis revealed that heavy metals and organics are present in excess concentration. Laboratory studies being carried out using chemical oxidants for possible treatment of colour and odour in raw water. The further studies are in progress.

Development of techniques I Exploration, Assessment and Management of Groundwater in Hardrock areas (CORE-005), (Year : 2018)
|
Pithampur IDA about 45 km from Indore has industries ranging from automobiles, pharmaceutical to textiles. The watersheds of two rivers namely Gambhir and Chambal, constitute the two study areas. The Gambhir and Chambal river have sub-parallel to dendritic drainage pattern. Thin quaternary alluvium consisting of clay, silt, fine to coarse sand, kankar and gravel is restricted to narrow patches along the course of rivers. Deccan trap basaltic rocks of Malwa group of Cretaceous to paleogene age (68-62 m.y) cover the entire area of the district. The region is characterized by lava flows of "pahoehoe" and "Aa" type. Mega-porphyritic flows sit at the top of the formations. The rocks belong to upper-cretaceous to paleogene age. The rocks have only secondary porosity in the form of fractures and joints. The aquifer type is mostly unconfined and semi-confined. The topsoil cover is predominantly clay. Gambhir river watershed covers an area of 90 sq km and industries located in this are mostly from automobile and chemical sector. Chambal river watershed has industries mostly from the automobile, chemical, textiles and pharmaceutical sector and covers approximately 210 sq.km. Apart from the existing industries, the area is going to witness further industrialization with a new Special Economic Zone (SEZ) coming up in the region. Integrated geohydrological, Remote sensing geophysical investigations carried out during last 2 years has helped generation of geohydrologic the database. Groundwater flow and mass transport modeling has been carried out to characterize the size of contaminant plumes, if any for present scenario.

CSIR Networked Programme on Pollution Monitoring Mitigation Systems and Devices (SMM-05), (Year : 2018)
|
In CSIR Networked Programme (SMM-05) one of the component is estimation of assimilative capacity of environmental media (air, water, land and biological), which has to be dealt by NEERI in three regions viz. Central India – Nagpur (M.S.) and Chhindwara (M.P.) districts, Coastal region - Visakhapatnam district (A.P.) and Hilly region - Mandi and Bilaspur districts (H.P.). The aims of the study are to develop the methodology for estimation of assimilative capacity with respect to various pollutants under different management options and development scenario; and delineation of assimilative capacity based standards for water sources for sustainable development. A meso-scale database on assimilative capacity of environmental media (air, water, land and biological) is essential for understanding the status of environment and for developing environmental quality standards, which will help easy and transparent decision making at policy, plan and project levels. A database for three representative regions would be generated, which would be available in public domain. Water quality analyses of major water resources of the two regions viz. Central India and Coastal region were carried out during post-monsoon as well as critical seasons. The analytical results showed that majority of water resources fall within the permissible limits of drinking water standards except coliform bacterial counts. It is observed that the water resources are suitable for irrigation purpose with few exceptions. Spatial variation in surface and groundwater quality was observed depending upon geological strata, pollution load by point and non-point sources and local ongoing practices in catchment area. The problem is aggravated in critical season, as pollution and chemical ingredients get concentrated in small amount of water resources. This calls for proper catchment area treatment strategies for surface water resources and conservation and protection of groundwater resources from being polluted. Using these resources for drinking purpose require proper water treatment with disinfection, whereas for irrigation purpose it requires adoption of proper irrigation methods and scheduling of irrigation in order to prevent water logging and salinity problems of land resources. Pollutants assimilative capacity of soils varies depending upon their intrinsic properties. One of the components in this project is Lysimetric study for Soil - Wastewater interaction. These studies will help in determining horizon wise pollutant retention capacity of soil, which will entail about quantum of groundwater pollution at wastewater application sites vis-à-vis soil pollution.

Studies on Environmental Status of Futala Lake and development of Management Plan for restoration of water quality on long term basis using ecotechnological approaches, (Year : 2017)
|
Futala lake near Telankhedi garden Nagpur has been developed as a picnic spot by Nagpur Improvement Trust (NIT). Water in the lake is turbid and contains algae, thus impairing the asthetics. The Institute in collaboration with NIT decided to rejuvenate the lake by applying ecotechnological methods like development of constructed wetland, application of chemicals and /or aeration in the lake. Water quality assessment including sediment analysis has been completed for physicochemical and biological analysis. Limnological studies covering biogeochemical processes are in progress for planning and management of improved water quality in the lake. The Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) values (4-13.5 and 7-44.8 respectively) indicates that lake water is polluted with organic content and that the status of the Futala Lake is in mesotrophic state. The final report of scheme with suitable recommendations is submitted to the sponsor (NIT, Nagpur).

Evaluation of water quality and biodiversity in the submergence area for the proposed Middle Vaitarna Dam, (Year : 2017)
|
Objective:
The Municipal Corporation of Greater Mumbai (MCGM) has proposed to develop additional source of drinking water supply due to increasing demand of water requirement for the megapolis of Mumbai. The project envisages the development of impoundage through construction of Middle Vaitarna dam to provide 455 MLD of water supply to the city. The raw water conveyance system is proposed from Modak Sagar (Lower Vaitarna dam) through a 7.5 km long tunnel of 3.5 m dia. upto Bel-nalla followed by 3.0 m dia. MS pipeline parallel to the existing pipelines in three parts on municipal land transporting raw water to proposed new Bhandup water treatment plant. The MCGM will execute the various components of this IV Mumbai Water Supply Project. As a result of construction of Middle Vaitarna Dam, approximately 630 ha area of forest will come under submergence. In order to estimate the loss of biodiversity caused due to submergence, it was felt necessary to conduct the study, so that ecosystem restoration programme as per MoEF guidelines can be initiated by the sponsor.
Scope:
- Evaluation of major vegetation in submergence area following quadrant method
- Application of diversity indices with reference to importance value index (IVI) of the area
- Ranking the varieties of trees starting from most important to least important species
Summary:
The major environment components studied during the survey of submergence area at MVD in March 2007 is land and biological environment. The terrestrial component in the proposed Middle Vaitarna dam project indicates that there will not be any appreciable changes as envisaged in the earlier reports on (A) EIA report of Middle Vaitarna Dam (B) Enumeration of trees for IV Mumbai (Middle Vaitarna) water supply project and (C) Catchment Area Treatment Plan. The review of all the reports for protecting the environment due to project activities, the present situation at the project site, the financial allocation for preservation of environment reveals that the project may be taken up for implementation. The environmental management plan suggested in the comprehensive EIA report and the requirements of forest department may scrupulously be followed to maximize the overall benefits apart from additional water supply need for the mega city of Mumbai.
