Summary: Land application of domestic wastewater has been adopted as one of the methods of wastewater treatment and disposal. Besides irrigation, it offers an alternative for the resource recovery from wastewater in the form of plant nutrients and water reuse through agriculture. Land application provides primary, secondary and tertiary treatment to the waste, all in a single operation with recycling and reuse benefits of water and nutrients for biomass production besides preventing the pollution of streams and lakes. Survey and periodic sampling of urban and industrial wastewater for physico-chemical and biological considerations: Site Details The project scheme is being operated at following sites
- Urban sewage/ wastewater Sugar industry (agro-based activity)
- Paper & pulp industry
- Distillery Industry in Tamil Nadu (proposed) Characteristics of Urban wastewater As per the objective of the project, urban wastewater was monitored in the city of Nagpur at three strategic locations from where the wastewater is being reused for irrigation purposes.
Nag river, which originates in the lake Ambazari, flows through the Nagpur city and carries the water from all the domestic as well as industrial sources in the city. Thus, today the river is turned into a wastewater carrying drain. Characteristically, only the part of city wastewater is treated in the sewage treatment plant and the treated wastewater is again discharged in the flowing drain. Out of these three sites, site
- receives the treated wastewater from the sewage pumping station while the other two sites are as good as for untreated wastewater. Site for urban sewage/ wastewater is selected about 12 km from the NEERI where wastewater from river Nag is available and used for irrigation purpose. The wastewater from Nagpur City is treated partially at Bhandewadi Sewage Pumping Station and disposed in the river Nag.
- It further flows to the experimental site at village Bharatwada about approx. 20 km from Nagpur. The wastewater characterization details in different seasons indicate that the concentration of pollutants are at lower profile in monsoon season due to dilution effect and high in summer. Sewage water is rich in nitrate and phosphate and are conducive for biomass production. However, the chlorides and sulphates in the sewage are also high indicating the anthropogenic influence. Seasonal heavy metal contents in sewage used for irrigation were monitored. It is observed that in general the concentrations are high in winter and summer seasons than the monsoon. Of all the heavy metals, the Ni contents are exceeding the permissible limits in all the seasons except monsoon.
- Cost effective assessment of wastewater irrigation practice using urban wastewater indicated that there is 2-3 fold increase in yield with respect to paddy and wheat. For chilli crop, the increase ranges from 8-10 fold. Cultivating aromatic plants is a new perspective, which is highly profitable when urban effluents are used for irrigation.

- Collection of information of water quality pertaining to each study area, before and after implementation of on-site sanitation systems, if available with local authorities, for comparison of the data generated through field study during project activities and assessment of impact
- Collection of data on soil characteristics through secondary sources in the project areas
- Monitoring of pollution indicator parameters, compilation and analysis of data on impact of on-site sanitation systems on water quality
- Establish a safe distance between on-site sanitation systems and ground water supply installation/source
- Identification of other possible sources of pollution, e.g. open defecation, sewerage, drainage, refused dumps leaching, open or unprotected wells, agricultural practices, e.g. application of fertilizers or nightsoil manure
- Delineation of sound guidelines, recommendations and action plan for monitoring, mitigation and remedial measures keeping in view aesthetics, health, environmental and economic criteria
Summary: The Government of India recommended a comprehensive study for prevention of contamination of water sources and to suggest corrective and remedial measures. The CPHEEO, Ministry of Urban Development, Government of India has retained NEERI to carry out study on impact of on-site sanitation systems on the quality of ground and surface water sources in ten selected cities. The project commenced with reconnaissance survey. Sampling and analysis have been carried out for all the sites selected in the ten cities for the four seasons. The analysis reveals that contamination of the ground water samples is significant in regions having secondary porosity. This scenario is present in Bhopal and Indore. In contrast, in cities like Kolkata and Lucknow, where there is alluvial cover, ground water samples located close to the on-site sanitation systems are least contaminated. The findings leave scope for further studies in respect of movement of contaminants in the unsaturated zone. There is need for a comprehensive study to investigate the movement of contaminants by high resolution geophysical imaging techniques.

To study the Quantum Particulate Dispersion from Mining Activity and its Effects on Plant at Chandrapur, (Year : 2015)
|
Aims and Objectives:
- Assess the particulate dispersion from the mining and related activities
- Study the effect of dust deposition on nearby plants/crops
- Recommend mitigation options to control productivity losses
Scope of Work:
- The proposed study area will be the WCL Mining area in Chandrapur District.
- The studies will span over a year comprising of three seasons namely winter, summer and monsoon.
- The study fields will be identified for crops as well as forest trees at strategic distances from the transport activities say 5 m ( adjacent to road side ), 100m, 200m, 300m
- Depositional rate of aerosols will be monitored manually in the field as well as from modeling exercises using software package
- Evaluation of particle deposition on leaf surface
- Morphological and physiological alternations (visible and invisible) will be assessed on seasonal basis in the crops • Overall growth of the crop plants on yield basis and on carbon will be computed
- Mitigation options to control productivity losses will be suggested in the final report
- Socio-economic assessment of the study area will be carried out by third party Non-Government Organization
- Two Workshops, one at the start of the project and other at the completion of the project `will be organized
Summary: During mining operations the particles are emitted in various operations like excavations, blasting and also during the transport of the mined products. Also, mining activity generates large quantities of over burden which is nothing but the loose earth material excavated and deposited in upside down position. This loosened material is also prone to be wind blown and disperse in the atmosphere. Considering the gravity of the problem, Western Coal Fields Ltd., Nagpur has retained National Environmental Engineering Research Institute (NEERI), Nagpur to study the quantum of particulate dispersion from mining activity and its effect on plants. Assessment of impact of transportation on standing vegetation on Hadasti Ghat Route and Visapur Ghat Route was undertaken for Rabbi & Kharip crops.
The crops selected for the study were:
- Jowar - Sorghum vulgare
- Tur - Cajanas cajan
- Chilli - Capsicum annuum
- Cotton - Gossypium hirsutum Hadasti Ghat Roue is currently under operation for sand transportation while Visapur and Seoni Ghat Routes are closed for sand transportation. Samples were collected at strategic distances from the Ghats i.e. Wardha river bank as starting point up to the jurisdiction of WCL area. At each location, the samples were collected at a 5, 100, 200, 300 meter distances from the edge of the road and coded as A, B, C, and D respectively
The results of the study indicate that
- The Dust dispersion in the ambient air due to sand transport is higher in the study area than the no activity zone
- The particulate concentration is higher in summer season (maximum value of 16.2 MT/km2 / month at Charwat village) than the winter season
- Water soluble fraction of the dust is negligible and the chemical composition of dust is harmless, innocuous as there is no component in the dust which is hazardous to plant growth
- The dust deposition on the leaf surfaces of crops in Hadsti Ghat route is more than the Visapur Ghat route which is not in operation during study period
- The morphological analyses of the crop plants : Jowar, Tur, Cotton and Chilli indicate that there is no correlation in the morphological parameters and dust deposition on the leaf surfaces
- The dust deposition is more on the leaves of crops which are at the edge of the road (5 m from road side) than 100 and 200 m distances respectively
- The particle size distribution indicates that the 60 % of the road dust is of >100 micron size i.e. does not remain suspended in the air over a long period and settle down under gravitational force nearer to the source
- The dust collected in the jar has 86 % of the particles in the range of >100 micron size while 45 % of dust particles deposited on the leaf surface are in the range of > 51 to < 100 micron size
- The soil analysis shows that the soils are poor in nutrient value (available N,P,K)
- There is poor irrigation facility in the study area due to which the crops on Visapur Ghat road which is not in operation during study period show low yields than the Hadasti Ghat route
- The farmers are not managing the fields according to the standard agricultural practices which is evident from poor irrigation facility and application of inadequate organic and synthetic fertilizers which seems to be the prime cause of low yields in the region.

Study of Arsenic Contamination in the Groundwater of Chowki Block, (Year : 2015)
|
The Public Health Engineering Department, Rajnandgaon Division, Madhya Pradesh retained the Institute in May 1999, to undertake the study of arsenic contaminatioin in the ground waters of Chowki Block in District Rajnandgaon. A team of scientists from the Institute visited 154 villages of Chowki Block and collected 813 water samples from hand pumps and dug wells. These water samples were analysed for arsenic and some other physico-chemical parameters (pH, conductivity, alkalinity, iron, and manganese). The analysis of arsenic was done by the Hydride Generation – Inductively Coupled Plasma (HG-ICP) spectroscopic method developed at the Institute. Out of total 813 water sources analysed, it was observed that 45 water sources in 11 villages contained arsenic above 50 μg/L, the BIS limit for arsenic in drinking water, the highest concentration being 1890 μg/L (or 1.89 mg/L). There are 129 sources which contained arsenic in the range 10 to 48 μg/L. The WHO Provisional Guideline Value for arsenic in drinking water is 10 μg/L. Thus, considering the Indian Standard specifications of BIS 10500 : 1991 there are 45 sources in the Chowki Block which exceed the limit for arsenic in drinking water, whereas there are 174 sources which exceed the limit of arsenic as per the Provisional Guideline Value of WHO. There are 122 sources in which arsenic values ranged between 2 to 9 μg/L. Remaining 157 sources showed arsenic Below Detectable Limit (BDL); the detectable limit for arsenic with HG-ICP method being 2 μg/L. Available technological options for providing arsenic free water are described in the report and recommendations have been made for future course of action.

Groundwater Modelling around Kovaya Limestone Mine, Gujarat Cement works, Amreli District, Gujarat, (Year : 2015)
|
The present study deals with geophysical and groundwater modeling in the watershed covering the Ultra Tech Cement plant of the Gujarat Cement Works (GCW), which is located at Kovaya in Amreli District, Gujarat. NEERI was retained by Central Mining Research Institute CMRI (Nagpur Zonal Centre) to undertake this task. The study area is based on the concept of watershed. The Ridge on the west, the Dhatarwadi River on the east and the Arabian Sea on the south form the boundaries of the watershed. It is bounded by latitudes 20.86o to 21.00o and longitudes 71.39o to 71.49o. The study area covers all the five villages namely Kovaya, Bhakodar, Babarkot, Varaswarup and Vand, which are covered in the lease area of the GCW. The study area includes Pit1 and Pit 2, where mining operation is going on at present. Resistivity Image profiling has been undertaken in selected profiles at representative locations to examine the signatures of seawater intrusion. Groundwater Modelling has been implemented in the study area using the Visual MODFLOW Professional software (Version 4.1).
Summary of the resistivity survey:
- The groundwater analysis indicates very high values of TDS, Chloride and Sodium in the observation wells in the study area. The high values of chloride and TDS can be on account of intrusion of seawater.
- The resistivity imaging studies also indicate very low resistivity anomalies (0-3 ohm- m) in certain profiles. The distribution of this low resistivity anomaly is not simple and it is distributed in a complex form. It exhibits a diffused form.
- The depth of the very low resistivity zone varied from 4 m to 13 m in different profiles. The very low resistivity zone is more prominent in Kovaya School and Power plant site. At Pit 1, the very low resistivity zone (0-3 ohm m) starts from approximately 8m depth.
- The profile at Vand shows very low resistivity anomalies at depth more than 10 m.
