Depending on where you live, your water source and any specific concerns you may have, your Culligan expert may also recommend sending in your sample for more in-depth laboratory testing. Water hardness Hard water is caused by the presence of excess magnesium and calcium, which are naturally ...
Further implications are bespoken to the application of DRL and would appear with testing. 3.2. DRL research in UWS In essence, there are many parameters to consider when selecting a DRL algorithm but through careful consideration of selecting the correct DRL components and algorithms. Depending on...
We did not target individual plants with our sampling device and often measured zero stems for a given sample (hence the zero-inflated data distribution) despite the proximity of multi-stemmed plants. More targeted approaches, with individual plants sampled or randomly selected plants harvested on ...
Dissolved metals were analyzed by Cornell University’s Nutrient Analysis Lab (Ithaca, NY, USA). Table 4. Water quality parameters evaluated, methodologies, and frequency of testing. ParameterMethod of AnalysisFrequency of Recording/Testing Dissolved Oxygen Hach SC100 Universal Controller & LDO® ...
During each strain excursion, the sample first contracted and then dilated; however, the consolidation was always greater than the dilation, so the net result was always an increasing density. Thus, sand- and silt- sized tailings can be compacted appreciably by repeated cycles of shear strain (...
The cartridges were first prepared by washing and equilibrating with 1 mL MeOH:AcOH (99:1) and 1 mL H2O:AcOH (99:1), respectively, before loading the sample. Again, the drip rate was kept to approximately one drop every 1 to 2 seconds, and a second wash of the microcentrifuge tube,...
“You have to have testing done. You have to an abatement contractor remove that material in a safe manner.” There is no known safe level of exposure to asbestos. This makes asbestos a serious health concern and subject to regulation by DEQ. “The reason it’s a problem is because it...

Sample location information (coordinates and altitude; Appendix 1) were recorded in the field using a handheld eTrex 20 GPS (Garmin, USA). 3.2. Analytical methods Physicochemical parameters including pH, temperature and electric conductivity (EC; Appendix 1) were measured in situ using a portable ...
Each soil core sample was well mixed and then divided into three parts: one part was placed immediately into high density polyethylene plastic bottles, sealed with Parafilm, and kept frozen until tritium analysis was performed; and the remaining two parts were collected in aluminum and polyethylene...
