Question

Discuss the relationship of monitoring work and site remediation which are needed for groundwater flow as a transport of contaminants.

For vadose zone soil water budget, present a conclusion of the THREE (3) distinct processes in groundwater recharge.

Answer 1

We are discussing about the relationship of monitoring work and site remediation which are needed groundwater flow as a transport of contaminants. Contaminants found in groundwater in a large range of physical, inorganic, organic, chemicals and radioactive parameters. These can be classified as natural and manmade. The increasing trends of industrial effluents and municipal sewage etc made a huge cause in the contamination of ground water. The remedies used to solve the contamination of groundwater have a relationship with the site and monitoring of work. Most groundwater treatments are the combination of technologies. Some of biological treatment techniques include bioaugmentation, bioventing, biosparging, bioslurping and phytoremediation. Some chemical treatment techniques are included in this process of remediation and there fore the monitoring of work is so important in the entire process. Monitoring includes to measure the level of groundwater by instruments, contaminant quantity and characteristics etc. This will help to find the type of method of remediation and work flow analysis.A monitoring system will implement in the site with a small diameter of 15-20 cm, angled 35 to 45 degree angled bore holes. We can compare the datas from different monitoring system for high result.

The vadoze zone also known as unsaturated zone. Normally groundwater recharge is using methods based on water balance, water table fluctuations, fixed factor of annual rainfall and tracer movement. These things are different for unsaturated soil zone. Hydrodynamic process gives areal average groundwater recharge .The unsaturated soil properties affect groundwater recharge, encompasses the unsaturated soil root zone, control flux of water. So the recharge of this type of soil zone includes hydrological methods. Infiltration process, analyse the impact of clay interbeds on percolation through the vadose zone, wetting front propagation and flux rates are the different process. The collective data will used to analyse the process and work flow
