	Drinking Water: Well Water Testing FAQ's- Parasitic Pathways - Division of Parasitic Diseases
		Check your well every spring to make sure there are no mechanical problems; test it once each year for germs and once every two to three years for harmful chemicals.
		However, as a well owner, it is up to you to maintain your well and have it tested regularly.
		The presence of nitrate in well water also depends on the geology of the land around your well.

	Boulder/GNC Water Well: How to chlorinate your water system
		Water, especially well water, should be tested for potability on a yearly basis.
		Well drillers and pump installers are required to use 100 parts per million (ppm)as a minimum, to disinfect the well after their work.
		To remove the chlorine and have your water chlorine free, the well and/or cistern must be emptied of the chlorinated water.

	DWR - Southern District - Well Standards
		The space between the monitoring well casing and the wall of the well boring, usually referred to as the "annular space," shall be effectively sealed to prevent it from being a preferential pathway for the movement of poor quality water, pollutants, and contaminants.
		Water level observation wells less than 15 feet in total depth that are used to assess root zone drainage in agricultural areas are exempt from an annular surface seal requirement, unless otherwise required by the enforcing agency.
		Water should be added to the bentonite transition seal prior to the placement of cement-based sealing materials where the bentonite is dry in the borehole.

	DWR - Southern District - Well Standards
		Medium to large-diameter pipe or casing used in water wells to maintain the well bore and house pumping equipment is not normally used for cathodic protection wells.
		Cathodic protection wells constructed with gravel backfill to land surface are particularly conducive to the movement of poor-quality water, pollutants, or contaminants.
		Water and electrolytes are sometimes introduced into cathodic protection wells through vent pipes, or gravel fill in the annulus, to keep wells functional where natural electrolytes are lacking.

	Water Well Information
		Water wells come in all shapes and sizes and need to be designed to suit the geologic conditions, the purpose for needing the water and to comply with local regulations.
		Critical decisions related to well depth, diameter and positioning of screens (if needed) are usually made on a site by site basis depending on the driller's experience in the local area and on the specific information on water strikes and rock conditions found during the drilling process.
		A well screen is an engineered device that may be used in wells to help maximize inflow from the aquifer and allow for long-term satisfactory operation of the well.

	Water Well \| Healthy Water \| Conservation
		Water is necessary for all living things to survive and as the earth and its water supplies become more polluted by industry and its waste, it is vital that we begin to change our attitudes towards it.
		Only 3% is fresh water and nearly 80% of what is fresh, is frozen in the polar ice caps and glaciers around the world.
		Groundwater is the portion of the water residing in underground aquifers.

	Cushing & Sons: Water Wells & Pumps
		Water from artesian rock wells comes from surface water that has percolated deep down into fissures in the bedrock, purifying itself as it travels through the topsoil, boulders, sand, silt and glacial material.
		Because we have drilled so many wells in NH, VT and MA, we have an enormous amount of data plus the intuitive experience to help locate your well on your property to maximize its delivery of water to your home or business.
		Correct water well design and casing installation is important to protect against contamination risks.

	Shock Disinfection Chlorination Private Water Well Water Supply bacterial contamination
		Unlike public water supplies that are regularly tested to ensure the water is safe to drink, individuals or families using private water supplies are responsible for testing for contamination.
		Shock chlorination or shock disinfection of the well consists of mixing sufficient chlorine-based chemical with the well water to create a solution containing 200 milligrams per liter (mg/l), or parts per million (ppm) of chlorine throughout the entire system (well, distribution pipeline, water heater, pressure tank and other equipment).
		Again, use a nearby hydrant and hose to circulate water through a portion of the distribution system to assure that the chlorine material is thoroughly mixed with well water.

	Water Well Helpline
		As the water is released into the widening section of the venturi, pressure drops, creating a suction effect at the constriction, and increasing the flow of water into the pipe.
		To cleanse your well of any particles that remain, use a foot valve at the bottom end of a long length of polyethylene tubing (it's called an inertia pump) to manually pump the water until it is silt free.
		A drop of well water placed on agar in a petri dish and incubated may indicate the presence or absence of bacteria.

	Information for Private Well Owners (Site not responding. Last check: 2007-10-26)
		As a private well owner, it is important to recognize that you are responsible for ensuring the quantity and quality of your own water supply.
		Proper construction, maintenance and destruction of water wells is necessary to not only provide a reliable water supply, but also to protect the groundwater resource.
		When a well is constructed, modified or destroyed, the law requires that the drilling contractor submit a Well Completion Report to DWR.

	Residential Well Program
		If a proposed well is to serve a small business, such as a service station, it is a Public Water Supply and needs to follow the Water Supply permitting procedures.
		Well owners 65 years of age and over or on public assistance such as Medicade, can receive one bacteriological analysis and one metals and minerals analysis per year at no charge (proof of age or assistance is necessary).
		A survey performed recently found that approximately 70% of the drinking water wells surveyed which were installed since the regulations were enacted failed to meet the regulations completely.
