Where were you on the mornings of May 14th, June 11th and July 16th, 2013? If you are a NH LoVoTECS sensor host more than likely you spent a portion of your morning at the site of your sensors collecting for the statewide “Snapshot” event. Water samples were collected between 7:00am and 4:00pm at active LoVoTECS sites for a total of 233 samples, representing about 79 sites per sampling event. Preliminary results are discussed in our March 2014 Newsletter, accessed via the link: March, 2014 NH LoVoTECS Newsletter Analytes of the Snapshot event and their significance to include them in the analysis are listed below.
|
Major
Ions
|
Calcium,
Magnesium, Sodium, Potassium, Chloride, Sulfate, Nitrate, which are the major
contributors to electrical conductivity.
|
|
Dissolved Organic Carbon &
Nitrogen
|
An important condition of water chemistry, significant to metal
transport and generally to aquatic ecosystems.
|
|
Phosphorus
|
A major factor for aquatic ecosystem
health. Often algal is limited by phosphorus availability.
|
|
Water Isotopes
|
Oxygen 18, Oxygen 16. This helps in identifying water sources.
|
|
Silica
|
Silicon dioxide is another factor for aquatic
ecosystem health, also higher levels of silicon dioxide are typically found
in groundwater due to the weathering of rocks and sand.
|
|
Ammonia
|
Ammonia is the preferred nitrogen-containing
nutrient for plant growth.
|
|
Water Isotopes
|
Oxygen 18, Oxygen 16, which are helpful in identifying water sources.
