Program description:
Water wells are susceptible to a variety of individual and combined fouling mechanisms. Understanding the specific reasons why a well has fouled or is experiencing reduced efficiency are key to developing the correct response. Biofouling, corrosion, pore development, mineral scale build-up, formation influence, are all common fouling issues that impact potable wells. The occurrence and frequency of common fouling mechanisms will be discussed with information derived from an active, investigative laboratory.
The session will explore the root cause of well fouling and share rates of occurrence on specific issues that commonly impact well systems. This information will then feed into a discussion on choices for maintenance, rehabilitation, or disinfection.
