Water in architecture of India played an important role in the culture. Indians developed the traditional hydro engineering to conserve Rain water, Ground water, river, and other natural resources. It could be seen since earliest times. Stepwells were first used as an art form by the Hindus and they influenced many other structures, Mughal Gardens are the examples of the incorporation of water in the design of Architecture. The designs of the gardens are of the medieval Islamic Period. Kaliadeh Mehel near Bheravgarh Fort at the bank of River Kshripa. Ujjain (Madhya Pradesh) is well known and one of the most famous historical landmarks of Madhya Pradesh, it is the fusion of Hindu – Persian architecture. The palace has the exclusive designed water system.

The research of hydrogeochemical mechanism of petroleum hydrocarbon in karst fissure groundwater system is important to predict the trend of petroleum hydrocarbons and the change of groundwater environment. We take the karst fissure water system as the research object, where there is a refinery. The variation of SO42-, HCO3-, NO3-, NO2-, HS- can be used as a hydrogeochemical sign of petroleum hydrocarbon pollution by analyzing the change of water quality parameters before and after karst fissure water contaminated by petroleum hydrocarbon. It has been also analyzed systematically that hydrogeochemical mechanism including desulfurization, denigration and ion exchange happen during the pollution process in the karst fissure water system. It is pointed out that the human activities have a great impact on the groundwater and changes of environment.

The objectives of this work were to investigate the relationships between characteristics of small non-community drinking water systems (SDWSs) and the performance of these systems with respect to Escherichia coli testing and risk ratings. Ontario-wide SDWS data were analysed using regression models with outcomes of (1) having an adverse E. coli test result in the 12 months prior to the last inspection and (2) the SDWS risk rating (high/medium vs. low risk) that is assigned by public health inspectors. Almost 34% (2,364/7,003) of SDWSs did not utilize treatment, more commonly for ground water than surface supplies (P < 0.001). The odds of having a positive E. coli test result were greater in systems using ground water with treatment (OR = 2.00; 95% CI 1.23–3.24) and surface water with treatment (OR = 1.97; 95% CI 1.05–3.71) compared to ground water with no treatment. The odds of having a water system rated high or medium compared to low risk was greater if the water system operated seasonally (OR = 1.36; 95% CI 1.17–1.59), had an adverse E. coli test result (OR = 1.66; 95% CI 1.09–2.53), and in specific facility types. This research helps to inform existing training opportunities available to SDWS operators in Ontario, and to better standardize the SDWS risk assessment process.

Increasing concern with nuclear waste isolation technology is leading to additional studies of naturally occurring isotopes in ground water. Such studies provide information on 1) the use of radionuclides to estimate ground-water travel times and/or residence times. This information can he an extremely useful adjunct to conventional hydrologic data in developing the understanding of regional hydrology needed in the site selection process, and 2) the use of natural radionuclides as analogues to the behavior of radionuclides of concern in nuclear waste.
