Hard Hat Microbiology: Our Interactions with Microbes in Groundwater and Wells Webinar Series, Part 3 of 3 — Prevention in Construction and Design, and Remediation (#815)
Microbial activity is a fact of life in groundwater systems, but proper planning and quality in design and construction minimizes adverse effects of natural biological activity and reduces the risk of contamination.
Failing that, or over time, wells that have been adversely affected by biofouling or microbial contamination can be rehabilitated instead of replaced in many cases, but this requires knowledge and skill.
By participating in this module, you will better understand:
- Construction planning and design
- Well sealing and sanitary handling of pumps and other well equipment
- Chlorination and other treatment methods
- Follow-up maintenance practices that serve to delay the need of rehabilitation or repeating rehabilitation treatments.
