Now, it is time to prepare for the EPA lab and further testing and analysis by creating a Laboratory Testing Notes table. We will create this table in just a minute. The agency has requested that you analyze the water samples for the following data: Salinity Mineral content Nitrogen Dissolved oxygena Turbidity The EPA has also informed you that the following equipment is available in the lab: pH meter ity ast

It seems like you want to create a Laboratory Testing Notes table for your water sample analysis based on the parameters requested by the EPA. Below is a draft of what such a table might look like. You can customize it further depending on your needs.

Laboratory Testing Notes Table

| Sample ID | Date Collected | Date Tested | Salinity (ppm) | Mineral Content (mg/L) | Nitrogen (mg/L) | Dissolved Oxygen (mg/L) | Turbidity (NTU) | pH Level | |-----------|----------------|-------------|-----------------|------------------------|------------------|-------------------------|------------------|----------| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |

Notes on Equipment

• pH Meter: Ensure the pH meter is calibrated before testing.
• Salinity: Use a salinity meter if available, or prepare a standard solution for conductivity measurements if required.
• Mineral Content: Consider using an atomic absorption spectrophotometer (AAS) or inductively coupled plasma (ICP) for precise measurements.
• Nitrogen: Kjeldahl method can be utilized for total nitrogen; ion-selective electrodes can also be employed.
• Dissolved Oxygen: A DO meter or Winkler titration method can be used.
• Turbidity: A turbidity meter or nephelometer can provide accurate measurements.

Each row of the table should document a single water sample's data as you conduct your tests and collect your results. Feel free to add or modify columns based on any additional parameters you might need or specific lab requirements.
