*Flow testing and pump system evaluations are indicative of function on the day they are conducted and are not, necessarily, reflective of future function.
**Additional pricing for water testing and report. In-house testing does not give an exact level, if an exact level is required, a sample should be sent to a certified laboratory.
The goal of a flow test is to evaluate the ability of the well to meet or exceed a flow test requirement. A flow test requirement is the amount of gallons per minute (gpm) needed over a period of time. For example: 3 gpm for 2 hours (this means that 360 gallons can be pumped over 120 minutes). A requirement can either be set by a mortgage company, and/or negotiated over between the buyer and seller in a house purchase. The requirement is the minimum water usage needed by the household in a 24 hour period. There are a number of recommendations which suggest how much water is adequate.
It is important to note that there are different types of water wells. The only well that is approved by the Department of Health as a potable source of water is a properly constructed Drilled Well, with a minimum of 20’ of steel casing (per NYSDOH). Springs, Well Points, and Dug Wells are considered surface-fed wells and have an increased risk of contamination and/or fluctuation in quantity. For this reason, a flow test is not a reliable method for evaluating the recharge of a surface-fed well, as it may be dependent upon seasonal changes – if it is a dry season, you may not have adequate water. In addition, a bacteria sample in a surface-fed well may be negative one day and positive another depending upon addition of new contaminants and thaw.
If a flow test is required, one will be conducted by a technician, but the report will include the Department of Health clause regarding potable water sources, and recommendation that a drilled well be installed, according to Department of Health regulations.
During the flow test: The technician will attempt to bypass the house, if able, by attaching a hose from the pressure tank and running to the outside, away from the foundation and well head. A water level indicator will be run down the well, while the water is pumped to measure the drawdown of the well. After a specified period of time, or once the well has drawn down to the pump intake, the test will be stopped and recharge of the well will be measured by evaluating how quickly the water level rises. The data will be evaluated and a report will be written, which will state whether the test met or did not meet the flow requirement. Recommendations will be included, as appropriate, with estimate(s) from local certified well contractor(s) for remediation.
It is the decision of this company to use Sterilene as the disinfection method.
Sterilene is a chlorine powder that is certified safe to NSF/ANSI 60 for private water well use. Unlike liquid chlorine or chlorine tablets, Sterilene is not dependent upon the water pH for how well it kills bacteria. Therefore, using Sterilene, versus liquid or pelleted bleach, decreases the likelihood of a second failing sample due to elevated pH. To learn more about Sterilene, please see the Resources page.
Reasons to chlorinate:
During the process of chlorination, the water may turn cloudy, discolored, or show new or increased sediment. This may last for only a short period, or may continue for a few days. It is recommended to run the well to clear via an outside spigot or a hose attached to the pressure tank and run to the outside. It is Well Inspection Services, Inc. is not responsible for plugged fittings/screens due to running the well or new or increased sediment, as a result of chlorination.
