Protecting What is Important
Prevention of ground water problems can prevent potential well problems in the future. Selecting your water well site is the start of prevention. Avoid low laying areas where surface run off can accumulate around the well head and avoid placed where standing water can saturate and seep through the annulus (soils around) the well casing and enter groundwater sources. Avoid septic tanks and septic fields, avoid barns, corrals and feed lots, be watchful of sink holes and landfills. These are common sources for contamination of water wells. Well construction is important. The area around the well head should be built up and capped with good quality clay and sloped to prevent accumulated water. Grouting is vital in dealing the annulus of the well, preventing surface contamination from seeping into the aquifers below and infiltrating your well. The use of a pitless adaptor below frost level also provides a sub-surface sanitary connection from well to the house system. Well casing should be free of cracks, holes and perforations above the water level. Opening and electrical conduits entering he well should be properly sealed. Tree roots seek moisture and can enter the well through perforations in the casings. Tree roots provide a passage for bacteria and dirt to contaminate the well. It is best the remove trees (15 meters- 50 ft around the well). Abandoned wells (old unused wells) are a large source of contamination and can be a hazard to public safety. These wells need to properly sealed by a reputable well decommissioner. We prefer tremie lines to pressurize the grout from the bottom to the top. This practice is much more reliable than top feed grouting.
