Introduction (1/2)

• Informal settlements living in the urban periphery of both

metro cities and developing urban regions of India are constantly exposed to a variety of hazards.

• One such community in Roorkee, Uttarakhand, India was

selected i.e. Bharatnagar, Mahigran Ward as part of case study on social vulnerability and disaster risk reduction.

• Moreover, a canal is passing through the study area is also a

flood prone area.

• The purpose of the canal was for the drainage but now it

becomes contaminated due to human activities.

• So many human activities happened in the neighbourhood like

majority of buildings are of concrete cement, is located near the canal.

Purpose

The aim is to assess the water quality and related hazards of Bharatnagar, Mahigran Ward in Roorkee, Uttarakhand, India. The objectives are as follows:

• To identify the location of highly contaminated groundwater that has

potential to cause adverse health effects.

• To analyse and evaluate the risk associated with that hazard

qualitatively. Limitations of the case study

• The case study has taken only within the buffer of 150 metres from

the canal.

• Only

10 parameters have considered for groundwater quality measurements.

• Temporal variation is limited to one time due to academic work.

Methodology

• Attributes of settlements and groundwater are mapped by using mobile apps.
• Collected data are interpolated to visualise the spatial variation of each parameter.

Results (6/6)

• Groundwater quality was qualitatively analysed with respect to

standards.

• Vulnerabilities and their extents were identified with regards to

groundwater quality available to the people in the study area.

• Spatial relation between the settlements and the groundwater

quality was qualitatively analysed thereby showing risks and infrastructural lacunae in the area.

Conclusions

• This assessment emphasizes mainly to consider the extension of stations

more especially in the informal settlements.

• Assessing groundwater can provide better quality of life.
• Highly overlapped settlements with highly affected ground water must be

considered for restriction so as to reduce hazard exposure and vulnerability to hazards.

• The spatial analysis of groundwater can provide in aiding further local

development plans which can integrate multi-hazard management by continuous collection of data with temporal variation.
