Environmental technology personal statement example

Why do you want to study this course or subject?

My college sits about ten minutes' walk from a brook that runs behind an industrial estate, and for two years I have been part of a volunteer group that clears it. What pulled me towards environmental technology was noticing that clearing rubbish only treats the visible part of the problem. After heavy rain the water turns cloudy and smells faintly of drains, and the volunteers who have been going longest could tell me exactly which outfall it came from but not what could be done about it. That gap between knowing something is wrong and being able to engineer a fix is what I want to work in. Chemistry gave me the first useful handle on it. Learning about dissolved oxygen, redox behaviour and how organic loading affects a water body made the brook legible in a way that picking up carrier bags never did. Geography added the catchment scale: rainfall, impermeable surfaces, combined sewer overflows. I like that environmental technology sits between the two, and that it is unapologetically practical. Reading about constructed wetlands and sustainable drainage systems, I was struck that some of the most effective interventions are deliberately low-energy, using gravity, plants and residence time rather than pumps. I also want to understand the parts I currently find hardest, particularly process design and mass balances, because I have seen how easily good intentions produce a scheme that is expensive to run and quietly abandoned. A degree that combines treatment processes, monitoring, regulation and materials seems the right training for work on water, waste and emissions, and I would like to end up in consultancy or utilities on the design side.

How have your qualifications and studies helped you to prepare?

I am studying Chemistry, Maths and Geography at A level. Chemistry has been the most directly useful subject and also the one I have had to work hardest at. Kinetics and equilibrium were initially abstract to me until I started sketching processes as boxes with inputs and outputs, which is now how I approach most calculation questions. Our practical work on titrations and colorimetry gave me enough confidence to plan my own analysis later, and I learned to be honest about uncertainty rather than quietly rounding results towards what I expected. Maths supports this: I use logarithms and exponential decay regularly when thinking about dilution and degradation, and I have found calculus more interesting since realising that rates of change describe how a treatment stage behaves over time rather than just being exam technique. Geography has been the subject that widened my thinking, particularly the units on hydrology and on resource management. Writing about water scarcity made me read about desalination energy costs and about how much treated water is lost through leakage before it reaches anyone, which is the kind of unglamorous engineering problem I find genuinely interesting. Alongside lessons I have been reading more widely, including Mark Miodownik's Stuff Matters, which changed how I look at materials selection and durability, and I follow the Environment Agency's published water classification information to understand how rivers are actually assessed. My teachers asked me to help run revision sessions for Year 12 chemistry students on moles and concentration, which forced me to explain the reasoning behind each step rather than reciting a method.

What else have you done to prepare outside of education, and why are these experiences useful?

The project I am proudest of grew out of the river club. With two classmates and the support of our chemistry technician, I set up a simple monitoring routine at three points along the brook: upstream of the industrial estate, at the outfall and about two hundred metres downstream. Over eleven weeks we recorded temperature, pH, nitrate and phosphate using test kits, and turbidity by eye against a printed card, always at the same time on a Saturday morning. The results were noisier than I hoped, and the most valuable part was learning why: inconsistent sampling depth, kits nearing their expiry, and the fact that one reading after rainfall could skew everything. We reported findings to the club and to the college science fair, where our display was chosen as the best in the environmental category. We were careful to present the data as indicative rather than conclusive, which a visiting judge commented on. My Saturday job is on the customer service desk of a garden and DIY centre, handling returns, complaints and questions about products. It has taught me to explain technical information plainly to people who are busy or annoyed, whether that is why a water butt filter needs cleaning or which compost is peat-free and why that matters. I have also become the person colleagues ask about our recycling and waste segregation, and I suggested relabelling the back-of-store bins after noticing cardboard being contaminated with plastic film. At the club I now help brief new volunteers on safety, including gloves, sharps and not entering the water. Between shifts, sampling and studying, I have learned to plan my week properly, which I expect to need at university.
