A typical water well is subject to mineral buildup, sand or bacterial issues over time. It is not uncommon for wells that are constructed properly to provide good clean water for many years. Some wells may require periodic cleaning to remove mineral buildup such as iron or manganese. Barnhart Pump Company has the specialized capability to inspect the condition inside a water well. Evaluating mineral buildup or identifying a crack in a well casing causing a sand problem or source of contamination is our expertise. Well video camera inspection service (link to page) can identify problem areas and render assessment as to the amount of mineral build-up and whether or not it has become problematic.
Iron bacteria when in the presence of oxygen precipitates out of solution causing an orange or brown staining of household plumbing fixtures, water-related appliances and points of discharge (garden hose, etc.) Over time, iron buildup creates additional problems such as plugging up pumps, pipes and clogging perforations in well casings which allow for entry of water into the well. These issues can cause low production, low pressure and decreased water volume to the house.
Buildup of mineral deposits can be mitigated through several different processes depending on the severity of the situation. A well casing is cleaned after removing the pump utilizing a brushing system. The perforated sections of the well casing in addition to the static water level zone can be scoured clean of mineral build-up. Heavy deposits of iron and mineral build-up that the brushes remove are lifted out of the well casing using a bailer. The bailing process can aid a great deal in restoring the production of a well. When a bailer enters the well, displacement forces water back out through the perforated section in the casing. When raised back up the well, it pulls water back in through the perforations creating a suction effect. The aggressive movement of water back and forth through the perforations flushes out mineral buildup. The process effectively cleans out the perforated section of the well allowing for greater volume of water production.
Although there is no universal fix for every well problem that may occur hundreds of feet below ground, brushing and bailing can be a very effective method of increasing the performance of a water well.
