Protecting the well from contamination involves several precautions. It is important to keep the area around the well clean and free from potential sources of contamination such as fertilizers, chemicals and sewage. The well seal and surrounding area should also be inspected regularly to ensure that it is properly sealed and protected. Sometimes it can be useful to install additional filters or cleaning systems. A professional well specialist can advise on best practices and possible safety measures to keep your well clean and safe.
