Manhattan College is continuing a water quality monitoring program for the Coalition with assistance from Saunders Trade and Technical High School in Yonkers. In twelve (12) sites samples are taken on a weekly or bi-weekly basis. The monitoring began in June 2006 and continued through one full-year.
The following are objectives of the study:
Objective 1: Continuously monitor the Saw Mill River for nutrients (ammonia, nitrate and total phosphorous) and fecal coliform bacteria.
Objective 2: Measure the spatial profile for sediment-bound metals along the entire saw Mill River.
Objective 3: Compile all historical data into a water and sediment quality database for the Saw Mill River.
The following parameters are being tested:
Surface water pH
Temperature
Conductivity
Nutrients
Ammonia
Nitrate
Total phosphorous
Fecal coliform bacteria
Sediment concentrations of heavy metals
Copper
Lead
Nickel
Cadmium
Zinc
Arsenic
Chromium
Sites
The sites are as follows:
| Site # | Site Location | River Mile |
| 1 | Chappaqua by train station | |
| 2 | Pleasantville Rd & Manville Rd | |
| 3 | Rt 9A at Rosedale Nursery | |
| 4 | Where river crosses Old Saw Mill River Rd, Eastview | |
| 5 | Elmsford, at Warehouse Lane | |
| 6 | Woodlands Lake outflow | |
| 7 | Macy Park, Ardsley | |
| 8 | Hearst St., Yonkers | 4.28 |
| 9 | Torre Place, Yonkers | 2.46 |
| 10 | Walsh Rd, War Memorial Field | 0.94 |
There are two more sites.
