Gujarat

The state is characterized by varied hydrogeology and vast areas are faced with typical groundwater quality problems like fluoride.

This link on the Central Public Health and Environmental Engineering Organisation (CPHEEO) website, presents data related to the status of the urban water, sanitation and solid waste management in India. The data includes information on:

• Status of water supply (physical)
• Status of urban water supply (financial)
• Status of urban sewerage/sanitation system
• Status of low cost sanitation
• Status of solid waste management

Data is included from different states in India namely Assam, Arunachal Pradesh, Karnataka, Gujarat, Maharashtra, Mizoram, Pondicherry, Sikkim and Tamilnadu respectively.

The field research study conducted by Carewater INREM Foundation attempts to establish the impacts of groundwater contamination with fluoride and arsenic in India. It maps the affliction severity, the medical cost and wage loss through a multi-location study in some villages in the States of Rajasthan, Andhra Pradesh, Karnataka and West Bengal.

The report by Carewater INREM Foundation deals with Reverse Osmosis (RO) technology, which is emerging as an important solution for drinking water treatment in rural Gujarat. RO plants with capacity ranging from 10 litres per hour (lph) to 6000 lph are now supplying drinking water in several hundred villages of the State. Small sized plants with capacity < 20 lph are used by individual families whereas medium to large sized plants (>100 lph) are being used for public consumption.

The report by Carewater INREM Foundation deals with groundwater and well water quality in the alluvial aquifers of Central Gujarat. Gujarat has a hydrogeology representative of almost all aquifer types and depositional & formation eras. Contamination of aquifers along with scarcity of groundwater resources due to increase in water demand and reduction in recharge of groundwater from changing landuse, is a problem in Central Gujarat.

The discussion paper by Carewater INREM Foundation on possibility of revival of dug wells in hard rock India through recharge is based on a field study across ten districts of the country. The study seeks to understand how localized governance of groundwater in hard rock areas is to be pursued through pricing (water, energy), legal regulation and community institutions. Water supply augmentation and demand management are both to be taken care of, directly through regulation or through indirect instruments such as pricing.

The report by Carewater INREM Foundation deals with the duel between popular science used in decision making by farmers and the formal science of hydrogeology that is based on scientific data collection. These two parallel streams of knowledge exist together, sometimes complement, and at other times are at conflict. People’s knowledge on hydrology is not ‘dying’, but thriving and growing well, refreshed continually by interfaces with science. In hard rock areas, the high hydrogeologic variability makes observation as important as theory since it is localized, pervasive and relevant to the needs of people.

The report presents a seasonal rainfall-runoff model developed for the Saurashtra region as well as parts of Narmada river basin. The successful planning and implementation of water resources projects require reliable data on volumetric runoff. It is not feasible to have discharge stations in all the river basins of interest given resource constraints. Therefore, regional rainfall-runoff models are preferred. The utility of such models can be improved if rainfall-runoff models for different regions are developed using data specific to the regions.
