Are you comfortable and willing to spend extended periods of time in hot, cold, and inclement weather?

Water quality is a hands-on industry for 365 days of the year, so you will need to be able to work through the elements. Consider the weather patterns in the region and whether or not you are able - and willing - to work through all seasons of the year. Do your research in advance. If you want to remain open to the position, then you will want your answer to be 'yes!' If you aren't sure or the answer is 'no,' then you might want to reconsider the job.
