Scholarship / Sustainable-Energy-Systems - to write a study objective for the Fulbright scholarship [3]

Hello guys,
I am writing my study objective and it is limited to 250 words, so I need your comments pertaining to my idea and grammatical structure,
I am a Civil engineer, working on solar power and water-wells in rural regions of Afghanistan.

Tips for the Study Research Objectives:

Working in the university's water labs, I learned many useful criteria for water projects, and that interested me in pursuing my career in relevant experiences after graduation. Since I work on solar power projects and water wells equipped with solar panels in the Citizen's Charter program, I have always wondered how to make these projects more efficient. They can also be used for agriculture purposes.

The problem arises when the wells cannot be drilled more than 10 meters due to the presence of saline-aquifers at deep depths, hence, due to the limitation of freshwater in these wells they can only be used for drinking purposes.

Considering the financial situation, and exact study of the area, the most optimal solution I have come up with is to operate a combined system of solar panels and direct sunlight radiation for salinization of this region's groundwater through condensation. In the summer with direct sunlight radiation and the winter with less water requirement, this water will be salinized by solar power. But in turn, people change their irrigation system to drip irrigation to reduce water demand.

That is why I aim to lead the Directorate of the Citizen's Charter Program on the provincial level so that I have sufficient competence in decision-making and helping to implementation of these programs in a more useful way. Firstly, implementing such projects will reduce unemployment -major causes of insecurity- in rural regions and secondly, make people familiar with the new systems that are kind of cultivation.

The opportunity to study my master's in Sustainable-Energy-Systems through highly respected Fulbright scholarship in the U.S is a privilege considering their academic reputation. I look forward to an experience that will enable me to enhance my knowledge of American culture and globalization.

I sincerely hope the admission committee will find my profile well-suited for this life-changing opportunity.

Graduate / I am going to write a study objective for the Fulbright scholarship [2]

Hello friends,
I am not familiar with the U.S educational system,
Hope you help me,

study objective

I have graduated from Civil Engineering, currently working on Solar power energy implementation and digging water wells. As I faced to a problem during my work, I come to the idea to participate in Fulbright scholarship for the M.S degree to solve this problem.

The problem is that ( the groundwater which is provided with the wells to the people is a little salty but people still use it for drinking ) now I want to gain knowledge in a field of Engineering to be able to solve this issue( by using solar power as a way of purification of salty water ) via the previous experiences I have gained from fieldwork, and the new knowledge I am going to acquire from this M.S degree.

The question is here that I am not sure what Major of engineering of the U.S educational system fits me for the master's degree which not be opposed to my goals??
