Which action is crucial after any changes in water quality?

Testing the water well is essential after changes in water quality because it helps to assess the extent and nature of the changes. Water quality can be affected by numerous factors such as agricultural runoff, industrial discharges, or natural processes. Without testing, it’s impossible to determine the specific contaminants present, the levels of those contaminants, or whether the water is safe for consumption and use.

Conducting tests allows for the identification of any harmful substances, which can inform necessary actions to improve water quality. It provides a baseline to track changes over time and helps in making informed decisions about treatment or remediation if needed. Regular testing is a critical component of safeguarding public health and ensuring access to safe drinking water.
