To find the percentage of contaminated wells, divide the number of contaminated wells (13) by the total number of wells (37), then multiply by 100.

[ \frac{13}{37} \times 100 = \frac{13}{37} \times \frac{100}{1} = \frac{1300}{37} ]

The result is approximately 35.14%. Therefore, 35.14% of the wells were contaminated.
