However, the system is still new to many people, including many State and local regulators. Once they are introduced to the system, though, most regulators whole-heartedly support the use of CMT wells. They look forward to the better plume definition afforded with multi-level monitoring, especially compared to the composite samples from long-screened monitoring wells that they have had to settle for in the past. A common concern expressed by the regulatory community is the integrity of the borehole annular seals that prevent vertical movement of groundwater between different zones. This is one of the key advantages of the CMT System. Unlike nested wells where several casings are placed in a single borehole, there is only one casing \u2013 or more accurately, one tube \u2013 in the borehole with the CMT System. This simplifies the installation and improves the reliability of annular seals installed between the various monitored zones. Another concern expressed by some regulators is the quality of the groundwater samples collected from CMT wells. The best way to inform your regulator of the advantages of multilevel monitoring using the CMT System is to direct them to the recently published paper on the CMT System authored by its inventors, Murray Einarson and John Cherry.

In some situations, those same compounds can diffuse through the polyethylene, either from outside of the well or from adjacent channels, potentially causing a positive sampling bias in some channels. Potential biases with hydrophyllic contaminants, e.g. MTBE or most inorganic compounds is minimal. A thorough discussion of these potential sampling biases is presented in the Einarson and Cherry Paper describing the CMT system that was published in the Fall 2002 issue of Groundwater Monitoring and Remediation.

In fact, the CMT System was designed in part because of the problems inherent with nested wells. Nested wells are multilevel wells that have multiple casings in a single borehole. That type of well construction was popular in the 1970s and early 1980s. However, the use of nested wells is strongly discouraged by US EPA and other regulatory agencies because of the many documented cases where poor seals between the casings led to cross-connection of the various monitored zones. Most boreholes are not perfectly straight or plumb, and the casings inevitably end up lying against each other in some portions of the borehole. Bentonite pellets and\/or cement grouts may not completely fill in the spaces between the casings, resulting in void spaces that allow cross-communication between the different monitoring zones. In areas where nested wells are still allowed, there are usually requirements that spacers be used to keep the various casings apart in the borehole. There is usually also a requirement that 2-inch annular seals be installed between each of the individual well casings. This requirement results in boreholes that must be 12 inches in diameter or larger. The increased cost of the larger boreholes quickly makes nested wells less attractive than clusters of individual wells, especially when the uncertainty of the annular seals is factored in. With the CMT System, the various monitoring channels are inside the CMT tubing. Thus, there is only one, smooth-walled tube within the borehole. The tubing is centered inside the borehole using Solinst's low-profile centralizers, and 2-inch-thick annular seals can be installed easily and reliably in a single borehole as small as 5.6 inches in diameter.\"<!-- [et_pb_line_break_holder] -->    }<!-- [et_pb_line_break_holder] -->  },{<!-- [et_pb_line_break_holder] -->    \"@type\": \"Question\",<!-- [et_pb_line_break_holder] -->    \"name\": \"Do CMT wells comply with state and county well construction standards?\",<!-- [et_pb_line_break_holder] -->    \"acceptedAnswer\": {<!-- [et_pb_line_break_holder] -->      \"@type\": \"Answer\",<!-- [et_pb_line_break_holder] -->      \"text\": \"Well construction standards vary from region to region, but CMT wells should be in full compliance with well construction standards in most areas.

Most importantly, samples from CMT wells are discrete samples from the aquifer, not composite samples typical of long-screened conventional monitoring wells. Consequently, if the concentration of a contaminant in a sample collected from a particular CMT channel is low, you can be confident that the concentration in the aquifer at that depth is indeed low, rather than being low because of dilution as may be the case with a conventional monitoring well. Additional discussion of the sampling biases associated with conventional monitoring wells and the technical advantages of multilevel groundwater monitoring is presented in our Papers Section. In addition, water samples collected from CMT wells are often less turbid than samples collected from conventional monitoring wells. The screen slot size and sand pack of a conventional monitoring well is often a compromise owing to the wide range of grain sizes present within the screened interval of most wells. The well screens and sand pack may be too small for the coarser fraction, but too large for the fine-grained layers within the screened zone. This leads to high levels of turbidity in the water samples since the fine-grained sediments are not effectively filtered by the well screens and sand pack. CMT wells, on the other hand, typically monitor short, discrete intervals in an aquifer. The well screen and sand pack in each monitored zone can be optimized for the grain size of the sediments within each interval. Each intake port in a CMT well can have a different well screen and sand pack size depending on the lithology of the aquifer materials in each monitored zone. This flexibility in well construction optimizes the filtration characteristics of the CMT well, resulting in clear, turbidity-free water samples. CMT wells have other advantages over conventional monitoring wells. First, the purge volume of CMT wells is very small. That means that there is less contaminated water requiring treatment or disposal during routine sampling. Take the case of a 4-zone CMT well that has ports at depths of 20, 40, 60, and 80 feet. Assuming that the static water level is 10 feet below the ground surface, the volume of water required to purge two times the \\\"casing volume\\\" of the four channels would be about 7 liters or less than 2 gallons! Second, CMT wells detect changes in piezometric pressure more accurately than traditional monitoring wells. Two- or 4-inch-diameter monitoring wells store a lot of water compared to the individual channels in a CMT well. The large amount of water stored in a conventional monitoring well means that the well will be slow to respond to changes in piezometric pressure in the aquifer. This is especially true in low-yield formations, where weeks and even months may be required to fill the well casings to the static water level. CMT wells, on the other hand, respond and equilibrate quickly because of the low volume of the various channels.\"<!-- [et_pb_line_break_holder] -->    }<!-- [et_pb_line_break_holder] -->  },{<!-- [et_pb_line_break_holder] -->    \"@type\": \"Question\",<!-- [et_pb_line_break_holder] -->    \"name\": \"How are CMT wells different than \\\"nested wells\\\"?\",<!-- [et_pb_line_break_holder] -->    \"acceptedAnswer\": {<!-- [et_pb_line_break_holder] -->      \"@type\": \"Answer\",<!-- [et_pb_line_break_holder] -->      \"text\": \"CMT wells are indeed very different than \\\"nested wells\\\". In fact, the CMT System was designed in part because of the problems inherent with nested wells. Nested wells are multilevel wells that have multiple casings in a single borehole. That type of well construction was popular in the 1970s and early 1980s. However, the use of nested wells is strongly discouraged by US EPA and other regulatory agencies because of the many documented cases where poor seals between the casings led to cross-connection of the various monitored zones.<!-- [et_pb_line_break_holder] --><!-- [et_pb_line_break_holder] -->Most boreholes are not perfectly straight or plumb, and the casings inevitably end up lying against each other in some portions of the borehole. Bentonite pellets and\/or cement grouts may not completely fill in the spaces between the casings, resulting in void spaces that allow cross-communication between the different monitoring zones. In areas where nested wells are still allowed, there are usually requirements that spacers be used to keep the various casings apart in the borehole. There is usually also a requirement that 2-inch annular seals be installed between each of the individual well casings. This requirement results in boreholes that must be 12 inches in diameter or larger. The increased cost of the larger boreholes quickly makes nested wells less attractive than clusters of individual wells, especially when the uncertainty of the annular seals is factored in. With the CMT System, the various monitoring channels are inside the CMT tubing. Thus, there is only one, smooth-walled tube within the borehole. The tubing is centered inside the borehole using Solinst's low-profile centralizers, and 2-inch-thick annular seals can be installed easily and reliably in a single borehole as small as 5.6 inches in diameter.\"<!-- [et_pb_line_break_holder] -->    }<!-- [et_pb_line_break_holder] -->  },{<!-- [et_pb_line_break_holder] -->    \"@type\": \"Question\",<!-- [et_pb_line_break_holder] -->    \"name\": \"Do CMT wells comply with state and county well construction standards?\",<!-- [et_pb_line_break_holder] -->    \"acceptedAnswer\": {<!-- [et_pb_line_break_holder] -->      \"@type\": \"Answer\",<!-- [et_pb_line_break_holder] -->      \"text\": \"Well construction standards vary from region to region, but CMT wells should be in full compliance with well construction standards in most areas.

However, the system is still new to many people, including many State and local regulators. Once they are introduced to the system, though, most regulators whole-heartedly support the use of CMT wells. They look forward to the better plume definition afforded with multi-level monitoring, especially compared to the composite samples from long-screened monitoring wells that they have had to settle for in the past. A common concern expressed by the regulatory community is the integrity of the borehole annular seals that prevent vertical movement of groundwater between different zones. This is one of the key advantages of the CMT System. Unlike nested wells where several casings are placed in a single borehole, there is only one casing - or more accurately, one tube - in the borehole with the CMT System. This simplifies the installation and improves the reliability of annular seals installed between the various monitored zones. Another concern expressed by some regulators is the quality of the groundwater samples collected from CMT wells. Until recently, the only way to sample CMT wells was with a Peristaltic Pump or Mini Inertial Pump. Now Solinst has a Micro Double Valve Pump and sample integrity is no longer an issue. Several government and university studies show that pneumatic pumps like the Micro Double Valve pump yield very high quality groundwater samples. The best way to inform your regulator of the advantages of multilevel monitoring using the CMT System is to direct them to the recently published paper on the CMT System authored by its inventors, Murray Einarson and John Cherry.

Also, be sure to use Solinst's low-profile centralizers to keep the CMT tubing centered in the borehole.

Be sure to measure the depth of the sand pack frequently with Solinst's Model 103 Tag Line while you are pouring the sand. This ensures that you don't bring the sand pack too high up in the borehole. Once the sand pack is above the bottom monitoring port, pour bentonite pellets to make a seal between the bottom monitoring zone and the overlying one. Contractors have reported good success using coated bentonite pellets for the annular seals. Pour the pellets slowly, and measure the depth of the seal frequently with the tag line to avoid adding too much bentonite. Continue adding alternating layers of sand pack and bentonite seals as described above, up to the levels specified in your well construction design diagram.

In some situations, those same compounds can diffuse through the polyethylene, either from outside of the well or from adjacent channels, potentially causing a positive sampling bias in some channels.

Most importantly, samples from CMT wells are discrete samples from the aquifer, not composite samples typical of long-screened conventional monitoring wells. Consequently, if the concentration of a contaminant in a sample collected from a particular CMT channel is low, you can be confident that the concentration in the aquifer at that depth is indeed low, rather than being low because of dilution as may be the case with a conventional monitoring well. Additional discussion of the sampling biases associated with conventional monitoring wells and the technical advantages of multilevel groundwater monitoring is presented in our Papers Section. In addition, water samples collected from CMT wells are often less turbid than samples collected from conventional monitoring wells. The screen slot size and sand pack of a conventional monitoring well is often a compromise owing to the wide range of grain sizes present within the screened interval of most wells. The well screens and sand pack may be too small for the coarser fraction, but too large for the fine-grained layers within the screened zone. This leads to high levels of turbidity in the water samples since the fine-grained sediments are not effectively filtered by the well screens and sand pack. CMT wells, on the other hand, typically monitor short, discrete intervals in an aquifer. The well screen and sand pack in each monitored zone can be optimized for the grain size of the sediments within each interval. Each intake port in a CMT well can have a different well screen and sand pack size depending on the lithology of the aquifer materials in each monitored zone. This flexibility in well construction optimizes the filtration characteristics of the CMT well, resulting in clear, turbidity-free water samples. CMT wells have other advantages over conventional monitoring wells. First, the purge volume of CMT wells is very small. That means that there is less contaminated water requiring treatment or disposal during routine sampling. Take the case of a 4-zone CMT well that has ports at depths of 20, 40, 60, and 80 feet. Assuming that the static water level is 10 feet below the ground surface, the volume of water required to purge two times the \\\"casing volume\\\" of the four channels would be about 13 liters or less than 3.5 gallons! Second, CMT wells detect changes in piezometric pressure more accurately than traditional monitoring wells. Two- or 4-inch-diameter monitoring wells store a lot of water compared to the individual channels in a CMT well. The large amount of water stored in a conventional monitoring well means that the well will be slow to respond to changes in piezometric pressure in the aquifer. This is especially true in low-yield formations, where weeks and even months may be required to recharge the well casings to the static water level. CMT wells, on the other hand, respond and equilibrate quickly because of the low volume of the various channels.\"<!-- [et_pb_line_break_holder] -->    }<!-- [et_pb_line_break_holder] -->  },{<!-- [et_pb_line_break_holder] -->    \"@type\": \"Question\",<!-- [et_pb_line_break_holder] -->    \"name\": \"I have flowing artesian conditions at my site.

You cannot, of course, develop CMT wells the way you would a water supply well, but that type of rigorous development isn't required with small-diameter monitoring wells. The goal of developing CMT wells, which is usually easily achieved, is to establish hydraulic connection with the formation. The well won't be 100% efficient, but the hydraulic head values measured in the well will be accurate, and the well will yield more than enough water to sample (assuming that the formation is reasonably permeable). If you added water when drilling the borehole or constructing the well, the best way of dealing with this is to simply wait several days for the water you've added to \\\"drift\\\" down gradient. For sites with typical groundwater velocities (0.5 to 2 feet per day), the water added during drilling and\/or well construction will have drifted away from the CMT intake ports in several days. If the water added during drilling has a different electrical conductivity (EC) than the formation water, you can monitor the EC in water pumped from the well to confirm that the drill water is gone. Some consultants have added potassium bromide (an inert tracer commonly used in groundwater research) as a tracer to the drill\/construction water and then monitored the purge water in the CMT well with a bromide-specific electrode to verify that the drill water is no longer in the vicinity of the CMT well prior to collecting samples.
