Wells should be checked and tested ANNUALLY for mechanical problems, cleanliness, and the presence of certain contaminants, such as coliform bacteria, nitrates/nitrites, and any other contaminants of local concern, (for example, arsenic and radon).
Heavy metals include: arsenic, antimony, cadmium, chromium, copper, lead, selenium and many more. Heavy metals can contaminate private wells through groundwater movement and surface water seepage and run-off. … Radionuclides can contaminate private wells through groundwater flow, waste water seepage and flooding.
Can bacteria in well water make you sick? yes, household well water that is contaminated likely holds coliform bacteria and E-coli. These microorganisms can be the cause of enteric diseases.
Dogs can become sick if they drink well water that is extremely hard, has high nitrate levels, or is contaminated by parasites, blue green algae, or other pollutants.
Boiling water makes it safe to drink in the event of some type of biological contamination. You can kill off bacteria and other organisms in a batch of water simply by bringing it a boil. Other types of pollutants, such as lead, are not so easily filtered out, however.
Homeowners with private wells should have their well water tested every 3 to 5 years for some contaminants, including bacteria.
Well Drilling Cost
Most projects range between $1,500 and $12,000. Expect to pay between $15 and $30 per foot of depth, or up to $50 for difficult terrain. Digging might be enough for shallow depths, ranging between $10 and $25 per foot. You can build a well on your property for several reasons.
$3,750 – $15,300 (Average Cost) The average cost to put in a new water well is $3,750 to $15,300 while installing a well and septic system costs $6,000 to $20,000. Well drilling costs $25 to $65 per foot for a complete installation, or $15 to $25 per foot just to drill.
You probably can drill your own well on your property. You, of course, would have to contact your local building department to see if there are any regulations that must be followed. Some states and cities may still charge you for the water that’s pulled from your land, but that’s a debate for another day.
Dug wells are holes in the ground dug by shovel or backhoe. Historically, a dug well was excavated below the groundwater table until incoming water exceeded the digger’s bailing rate. … These features help to prevent contaminants from traveling along the outside of the casing or through the casing and into the well.
If you want to find the the location to drill with the highest potential yield you need find the location to drill that the aquifer is the thickest and has the highest hydraulic conductivity. Using seismic technology and software customized for imaging aquifers we are able to find this for you before drilling.
Subtracting the depth to water from total well depth will give you length of the water column. Multiply the length of water column in feet by the gallon volume per given diameter. For example, a 4-inch-diameter well has 0.65 gallons of water per foot and a 6-inch diameter well has 1.47 gallons per foot.
As a general guidance, personal drinking water wells should have a minimum horizontal distance of at least 10 feet and preferably 25 feet from such boundaries. State or local standards may be less or more stringent in your area. Contact your local health department for more information in your area.
If there are no wells in the area, or not enough information is available on existing ones, the hydrologist may contract with a well driller to put down some test holes. At these holes a pumping or aquifer test will be conducted. These tests indicate the water-bearing properties of the aquifer tapped by the well.
Locate the wellhead in your yard. This is the top of your well. There should be cap or seal on the top of the casing (pipe) that should extend at least twelve inches above the ground to keep contaminants from entering the system. Soil should slope away from the wellhead so surface water doesn’t puddle.
