We accept cash, checks and all major credit cards. For commercial accounts, credit terms can be arranged.
Yes. An employee or it’s "authorized representative" of a NJDEP certified laboratory must collect the sample. An employee of a NJDEP certified laboratory must perform the field pH analysis.
Yes. A NJDEP certified laboratory must analyze the sample.
The sampling technician is instructed to ask you certain questions to help insure that sampling in done correctly. Take a moment to read over this list.
Water samples will have to be collected prior to treatment – raw water.
For the PWTA, the water sample must be collected prior to treatment. There should be a tap or spigot before the water treatment system. Or, the system may need to be disconnected or disabled prior to sample collection.
Yes, but this information would be used for the buyer & seller to demonstrate that the water treatment system is working correctly. The NJDEP recommends (but does not require) treated samples be collected and analyzed for those compounds where treatment is in place.
Possibly, especially if there is a special concern about other possible contaminants being present. The PWTA tests for over 30 contaminants, however there are tests that can detect other dangerous chemicals (e.g., pesticides and a "first draw" sample for lead).
You should verify that your local ordinance is still required in addition to the PWTA requirements. Otherwise, both sets of regulations will be required.
It is recommended that you conduct a follow-up test to confirm the concentrations. Even if the initial test is low, it is useful to conduct the second test to confirm the results.
Most of the chemical data that is reported for water is expressed as a concentration: a mass of chemical per unit volume of water.
In Very basic conceptual terms:
It is EXTREMELY MISLEADING to interpret these analogies to minimize the magnitude of the risks. Miniscule amounts of certain substances can contaminate water.
Anyone who is concerned about possible contamination of their water should test.
The only way to tell s to test for the specific contaminant. Because your health is dependent on quality data, use a laboratory that is NJDEP certified to conduct drinking water analyses using low-level methodology.
Standard turnaround is about 2 weeks after sample collection. Quicker turnarounds are available but you should arrange for quicker service ahead of time.
The following information, and more: who collected the sample, the analytical methods used, location of the well, the point where the sample was collected, the date and time the sample was collected/analyzed, the well permit number (if known), and results.
The format for the test report is specified by the NJDEP. The test report is detailed and may have certain terminology or technical terms that may need explaining. Just assemble your list of questions and give us a call.
Yes. The reporting laboratory is required to electronically submit the results to the NJDEP. The NJDEP will forward the results of well test failures to the local health department. Additionally, if the analysis result for nitrate or fecal coliform exceeds the limit, the laboratory shall, within 24 hours of obtaining the results, notify the person paying for the water test as well as the appropriate health authority.
All results, except the total coliform bacteria analyses, are valid for 1 year from the date of sample collection. The total coliform bacteria is valid for 6 months. If a new well were drilled, a complete re-testing would need to be performed.
The public agencies as well as the laboratory are obligated to keep the specifics of the data confidential.
