5. To read the result, turn the test strip over so that both pads face away from you. 6. Compare the color of the small pad to the color chart on the container. 7. Read the result through the clear plastic of the test strip. 8. Record the result on the Monitoring Locations Inspection and Sampling Field Sheet. pH and Total Chlorine (LaMotte # 5049-36) pH is measured to indicate potential industrial discharges. Total chlorine is measured to indicate a tap water leak into the storm sewer system or possibly discharge of chlorinated pool/spa water. 1. Immerse test strip and remove with pads face up. 2. Do not shake off excess water. 3. Wait 15 seconds and immediately hold up vertically against the color chart on container. 4. Record the pH result on the Monitoring Locations Inspection and Sampling Field Sheet. 5. Using the same strip, record the results for Total Chlorine Nitrite and Nitrate (LaMotte # 5049-39) Sources of nitrite (NO2) and nitrate (NO3) in urban stormwater runoff include lawn and garden fertilizers, pet waste and failing septic tanks. 1. Using at least a cup-size sample, immerse test strip for 2 seconds and remove with pads face up. 2. Do not shake off excess water. 3. Wait 60 seconds and immediately hold up vertically against the color chart on container. 4. Record the Nitrite result on the Monitoring Locations Inspection and Sampling Field Sheet. 5. Using the same strip, record the results for Nitrate. Phosphate (HACH # 4315-75) Sources of phosphate/phosphorus in urban runoff include plant and leaf litter, soil particles, pet waste, road salt and lawn fertilizer. Lawns and roads account for the greatest loading. 1. Dip a strip into water for 5 seconds and remove. 2. Hold the strip level, with pad side up, for 45 seconds. 3. Do not shake excess water from the strip. 4. Compare the color of the small pad to the color chart on the container. 5. Record the result on the Monitoring Locations Inspection and Sampling Field Sheet. Additional Testing 1
