Capital Well Clean Water Center FAQs
What exactly is a drilled well?
A drilled well consists of a hole bored into the ground, with the upper part being lined with casing. The casing prevents the collapse of the borehole walls and (with a drive shoe or grout seal) prevents surface or subsurface contaminants from entering the water supply. The casing also provides a housing for a pumping mechanism and for the pipe that moves water from the pump to the surface. The quality of materials used in well construction is an important factor. Casing must meet certain specifications, since substandard pipe does not have sufficient strength to withstand driving without potential damage to the joints. Such damage may allow shallow or surface water to enter the well.
How much water will I need?
It depends on what the water demands are for your household, business, farm, or commercial property. For example, do you have irrigation, a hot tub, multiple bathrooms and kitchens, and other utilities that demand water? All these items make a difference from home to home or business to business. When you meet with our clean water professionals they'll be able to discuss your water usage and needs.
How often should I test my well water?
The National Ground Water Association (NGWA) recommends well owners test their water at least annually for bacteria, nitrates, and any contaminants of local concern. More frequent testing should be considered if:
- Change in taste, odor, or appearance of the well water, or if a problem occurs such as a broken well cap, inundation by floodwaters, or a new contamination source
- Well has a history of bacterial contamination
- Septic system has recently malfunctioned
- Family members or house guests have recurrent incidents of gastrointestinal illness
- Infants or children are living in the home
- Monitor the efficiency and performance of home water treatment equipment.
