加拿大Solinst多水位地下水監測系統（401）Waterloo 401

 產品名稱：地下水監測系統
品牌：Solinst
產地：加拿大
型號：401



多水位地下水監測系統401允許在單個鉆孔中從多個孤立區域進行地下水測量和采樣。靈活的設計允許用戶為每個監控項目定制一個系統。


為什么選擇多水位地下水監測系統：提供對地下條件的更清晰理解
當監測單個鉆孔中不同深度的一系列離散隔離層段時，可以捕獲高質量的數據。Multilevels 以水平和垂直流動的形式提供的詳細信息，以及污染物的離散區域采樣，對于準確的現場評估是必要的。
 

• 改善現場評估和風險管理：

    多層次提供高分辨率數據，用于輸入更具代表性的“動態”概念場地模型。
    地下水流路徑上的多級橫斷面提供了用于質量通量計算的**數據。這已被證明是現場評估的重要工具，需要對受體的**污染物濃度/風險進行實際估計。

• 多級提供三維地下水數據。

    通過使用來自一系列多級的詳細 3-D 數據來優化主動修復的性能。隨后，橫斷面可用于評估所選修復方案的成功，并確定任何需要改進的領域。

• 經濟學是有道理的

    經證實可降低鉆井和鉆井廢料的成本。
    當清除量減少時，現場人員的時間和處理成本很低。多級端口包含的離散間隔允許更小的吹掃體積、對液位變化的快速響應，是低流量采樣技術的理想選擇。

• 用長篩井克服偏差

    長篩上的污染物混合掩蓋了垂直變化，導致低估了羽流的全部范圍并稀釋了污染物的真實濃度。
    井內的環境垂直流動有可能將污染物傳輸到非污染區域。



Waterloo地下水監測系統：
Waterloo系統用于從單個鉆孔中的許多離散隔離區域獲取地下水樣本、水頭測量值和滲透率測量值。


 

Waterloo系統的優勢：

• 詳細的流動深度和濃度
• 降低項目成本
• 減少吹掃和采樣時間
• 更少的鉆孔
• 減少現場干擾
• 多種監控選項
• 在離散污染區隔離采樣
• 高分辨率場地表征

 

詳細的數據：

• 當在現場使用多個滑鐵盧系統時，它們可以以合理的成本獲得詳細的 3D 地下水信息。更少的鉆孔是一個優勢，并且可以減少監控時間。
• 模塊化系統可以針對獨特的項目要求進行定制。這允許使用適用于基巖、覆蓋層或組合應用的選項將監測區域放置在所需的深度。
• 離散區域監測是獲得用于現場解釋和評估的準確數據的**方法。多級橫斷面提供了計算質量通量和保守評估受體風險所需的詳細數據。

 

多端口安裝：

• 覆蓋層或基巖裝置

- 允許在任何地質環境中監測多個區域
- 地下水或滲流帶裝置

• 永久Waterloo封隔器

- 專為基巖或套管孔設計
- 專為永久密封而設計


模塊化密封接頭：
滑鐵盧系統的滑套式接頭設計使用尼龍剪線和雙 O 形密封圈。這提供了可靠的防漏接頭，因此滑鐵盧套管柱的核心與外部地層水隔離。地下水只能通過端口桿和附加的監測設備進入。這種防水密封還可防止套管內的封隔器充氣水與套管外的地層水接觸。

帶剪切線的 O 形圈接頭


定制井口管匯：
歧管在地面完成系統。它組織、識別和協調來自每個監控區域的管道和/或電纜。

歧管允許依次連接到每個專用傳感器，以及用于操作泵的簡單、一步連接。選擇專用泵時，獨特的井口允許單獨吹掃單個區域，或同時吹掃許多區域以降低現場時間。

Why Multilevels: Provide a Clearer Understanding of Subsurface Conditions


Superior quality of data is captured when monitoring a series of discrete isolated intervals at various depths in a single borehole. The detailed information provided by Multilevels in the form of horizontal and vertical flow, in conjunction with discrete zone sampling for contaminants, is necessary for accurate site assessments.



Improve Site Assessments and Risk Management：

• Multilevels provide high resolution data for input into more representative 'dynamic' conceptual site models.
• Transects of Multilevels across a groundwater flow path provide the best data to use for Mass Flux calculations. This has proven to be an important tool for site assessments that require realistic estimates of maximum contaminant concentration/risk to receptors.
• Optimize performance of active remediation by using detailed 3-D data from a series of Multilevels. Subsequently, transects can be used to evaluate the success of the chosen remediation option and identify any areas requiring improvements.

The Economics Make Sense：

• Proven cost reductions for drilling and drilling waste.
• Field personnel time and disposal costs are low, when purge volumes are reduced. The discrete interval that a Multilevel port encompasses allows for smaller purge volumes, rapid responses to level changes and is ideal for low flow sampling techniques.

Overcome Biases with Long Screened Wells：

• Contaminant mixing over long screens masks vertical variations resulting in underestimating the full extent of plumes and diluting the true concentration of contaminants.
• Ambient vertical flow within the well has potential to transmit contaminants to non-contaminated zones.

Waterloo Multilevel Groundwater Monitoring System：
The Waterloo System is used to obtain groundwater samples, hydraulic head measurements and permeability measurements from many discretely isolated zones in a single borehole.

 

Advantages of the Waterloo System：

• Detailed depth of flow and concentrations
• Reduced project costs
• Purging and sampling times reduced
• Fewer drilled holes
• Reduced site disturbance
• Variety of monitoring options
• Isolate sampling at discrete contaminant zones
• High-resolution site characterization

• Detailed 3-D Data：

When a number of Waterloo Systems are used at a site, they allow detailed three-dimensional groundwater information to be obtained at a reasonable cost. Fewer drilled holes are an advantage and monitoring times are reduced.

The modular system can be customized for unique project requirements. This allows monitoring zones to be placed at desired depths using options suitable for either bedrock, overburden or combination applications.

Discrete zone monitoring is the only means of obtaining accurate data for site interpretation and assessments. Transects of Multilevels provide the detailed data necessary to calculate mass flux and conservatively assess risk to receptors.

 

Multi-Port Installations：

• Overburden or Bedrock Installations

- Allow monitoring of multiple zones in any geologic setting
- Groundwater or vadose zone installations

• Permanent Waterloo Packers

- Designed for bedrock or cased holes
- Engineered for permanent seals


Modular Sealing Joints：
The slip-on joint design of the Waterloo System uses a nylon shear wire and a double o-ring seal. This gives reliable, leakproof joints so that the core of the Waterloo casing string is isolated from external formation waters. Groundwater is only accessible via the port stems and attached monitoring equipment. This water-tight seal also prevents contact between packer inflation water inside the casing and the formation water outside the casing.


Customized Wellhead Manifolds：
The manifold completes the system at surface. It organizes, identifies, and coordinates the tubes and/or cables from each monitoring zone.

The manifold allows connection to each dedicated transducer in turn, and a simple, one-step connection for operation of pumps. When dedicated pumps are selected, a unique wellhead allows individual zones to be purged separately, or purging of many zones simultaneously to reduce field times.
