We are looking for tests during potentially high phosphate events. This means pollution events, such as spring melts, sewage overflows, agriculture run-off or failing septic systems, where phosphate levels will be very high.
How many tests for high level phosphate do you anticipate you can do?
When do you plan to conduct the tests?
Throughout the testing season
This is not required, however, the more samples we can compare to lab results, the faster we can get more accurate readings. We will ask you to share your lab results.
Will you be also sending these phosphate (or phosphorous) samples to a lab?
Yes, all or most of them
Rarely, but it's possible
Do you follow a protocol for collecting lab samples? If yes, please describe it briefly
When can you share lab results?
Right away (within a few days)
Later - we process in batches
Your privacy is important to us, this will only be used for shipment of the testing package
