The chart details the length of different quality water in rivers in England.
Sample Response
The chart illustrates the quality of water rivers in England, namely good, fair and poor, over a period of 10 years.
Overall, it is noticeable that the length of good-quality rivers was generally the highestwater quality in England has been generally good over the entire period, except 1993.
At the start of the period,To commence with, the length of rivers by water quality in Englandthe water quality of rivers in Britain in 1993 was highest for fair-quality water at 12,500 kmpredominantly fair at 12,000km. Also, 9,500 km9.5000km of rivers were poor in quality, with 12,000km of rivers being of good qualitywater sources being a good source. From 1994 to 1998, around 20,000 km of the country’s riversmost of the country’s rivers, around 20,000km, were of good quality, while the length of fair-quality rivers ranged from 10,000 to 13,000 kmwith 10,000km of streams which were fairly clean. Moreover, from 1994 to 2003from 1994 throughout to the rest of the period given, water sources in England whose quality was poor ranged from 2,000 to 4,500 kmaccounted for around 5000km.
Additionally, from 1999 to 2002from 1999-2002, the length of good-quality rivers increasedmost of the rivers in Britain saw a rise in good water quality to 24,000 kmnearly 25,000km before falling to 21,000 km in 2003before declining to around 20,000km of water sources which were clean in the country. Within the same period, the length of riverssources of streams in Britain whose cleanliness was fair got around 9,000km with the same figure for quality water rivers in the year 2003.
Why this response received Band 6.0
The response is clearly structured and identifies good water as the dominant category for most years. Its main weakness is imprecise selection and reporting of the chart, particularly the incomplete overview and the claim that poor-quality water remained around 5,000 km despite substantial variation. Prioritise an overview of the rise in good quality and declines in fair and poor water, then support it with accurate figures.
IELTS Writing Criteria Scores
Task Achievement
The main category is identified and several periods are described, but the overview is incomplete and some figures and trends are inaccurate or overgeneralised.
Summarise the overall rise in good-quality river length and the falls in fair and poor categories, then use precise values such as 12.5 thousand km for fair water in 1993.
Coherence and Cohesion
The response follows a clear introduction-overview-detail structure and broadly groups the data by time, although some linking is mechanical and comparisons are not always sharply developed.
Organise the details around the three quality trends and use direct comparisons instead of relying on sequencing phrases such as 'Additionally' and 'Within the same period'.
Lexical Resource
There is sufficient vocabulary for trends and quantities, but awkward or inaccurate phrases such as 'quality water rivers' and 'fairly clean' reduce precision.
Use stable chart terminology such as 'the length of rivers with good, fair, or poor water quality' and precise change verbs throughout.
Grammatical Range and Accuracy
A mix of simple and complex structures communicates the main meaning, but recurring problems with noun phrases, clauses, and numerical expression reduce control.
Simplify overloaded sentences and check noun order, agreement, and number formatting, especially in phrases describing river length and water-quality categories.
