Lake Pond River Essential Minerals in Water role in aquatic growth and algae blooms.
Lake Pond River Essential Minerals in Water. Outdoor experiment for a first time science fair project. Water samples from lakes, creeks, ponds, rivers etc are tested for basic nutrients required for biological growth. Testing only takes a few minutes per sample.
# 552 Lake, Pond and River Essential Minerals in Water
Each water sample is tested for this Set of parameters: Phosphate, Nitrate, Nitrite, Dissolved Metals (Combined Metals Cu+2, Co+2, Zn+2, Cd+2, Ni+2, etc.) and Iron +2 (5 tests per set).
Dissolved Phosphate test scale
# 140 Dissolved Phosphate in Water
Colorimetric test strips. (1 test per strip)
Testing for Dissolved Phosphate in water is common, but
usually found in low concentrations. Because of low
concentrations, phosphate is involved with regulating bilogical growth and productivity in natural waters.
The color chart for this test allows you to read Dissolved
Phosphate in micrograms/L or ppb.
The Color Comparator Chart for this test allows you to read Phosphate levels in water at:
~0, 200, 400, 600, 1000, 2500 microgms/L or ppb.
(Note: concentration units are micrograms per Liter or parts per billion).
Results are obtained from this test in about 1 minute.
Nitrate and Nitrite test scales
# 135 Nitrate and Nitrite in Water
Colorimetric test strips. (2 tests per strip)
Nitrate / Nitrite test strips are for testing water in many applications from drinking water to water used to wash produce.
Nitrates and nitrites occur normally in nature from the breakdown of ammonia in the nitrogen life cycle. Nitrates in nature cause plant and algae growth that may affect the balance of water-based ecosystems.
Nitrate is found in fertilizers and animal waste. Rain tends to wash fertilizers containing nitrates into nearby natural water systems and ground water. Groundwater used as drinking water that contains nitrogen represents a hazard to babies. Many die every year as a result from “Blue Baby Syndrome.”
The Color Comparator Chart for this test reports concentrations compatible with EPA limits of total nitrogen and nitrite nitrogen in water.
The test reports levels of:
NO3 (as N): 0, 0.5, 2.0, 5, 10, 20, 50 mg/L or ppm;
NO2 (as N): 0.15, 0.3, 1, 1.5, 3, 10 mg/L or ppm.
Results are obtained from this test in 1 minute.
Dissolved Metals test scale
#150 Dissolved Metals in Water
Colorimetric test strips. (1 test per strip)
Testing for Dissolved Metals, also referred to as Trace Metals, in tap water is very common and is very quick and easy with these
semiquantitative test strips. Each test strip result indicates the combined presence of heavy metals (Cu+2, Co+2, Zn+2, Cd+2, Ni+2, Pb+2, etc…) in water.
The color chart for this test allows you to read Dissolved Metals in micrograms/L (ugms/L) or parts per billion (ppb). The color chart was calibrated using mixed metals solution.
In the presence of one specific metal, or a high concentration of a specific metal, colors such as purple, red, or brown may appear. In this situation, matching levels based on color
intensity may be necessary to reach semiquantative results.
The Color Comparator Chart for this test reports mixed Dissolved Metals levels in water at:
<10, 20, 50, 100, 200, 400, 1000 microgms/L or ppb.
(Note: concentration units are micrograms per Liter or
parts per billion: ppb.)
Results are obtained from this test in 2 1/2 minutes.
Iron (Fe+2) test scale
# 155 Iron (Fe+2) in Water
Colorimetric test strips. (1 test per strip)
Testing for Iron in tap water is very common and is very quick. Each test strip result indicates the presence of Iron in the ferrous (Fe+2) state in water.
The color chart for this test allows you to read Iron+2 in milligram/L or ppm.
The presence of Iron in water contributes to the reddish brown stains on porcelin and plumbing fixtures. It can also add a metalic taste and odor to drinking water.
The Color Comparator Chart for this test reports mixed Iron (Fe+2) levels in water at:
0.0, 0.1, 0.3, 1.0, 5.0 milligms/L or ppm.
(Note: concentration units are milligrams per Liter or parts per million). Best results are obtained when water is room temperature.
Results are obtained from this test in 2 1/2 minutes.
