To find the total number of water samples that need testing, you can set up the equation based on the information given:
Let \( x \) be the total number of water samples. According to the problem, 25% of \( x \) equals 56 samples.
This can be expressed as the equation:
\[
0.25x = 56
\]
To find \( x \), divide both sides of the equation by 0.25:
\[
x = \frac{56}{0.25}
\]
Calculating that gives:
\[
x = 56 \times 4 = 224
\]
Therefore, there are a total of **224** water samples to be tested.
