2018 ARM Drop-off Locations Map
The map below has a point on the exact building for each drop-off location. Volunteers, please consult the letter that arrived with your sampling bottles to determine with drop-off location you should use.
Site maps are also available in PDF format by county:
- Berkshire County
- Bristol County
- Essex County
- Franklin County
- Hampden County
- Hampshire County
- Middlesex County
- Norfolk County
- Plymouth County
- Worcester North County
- Worcester South County
- If sampling by a bridge, try to collect sample upstream of the bridge.
- If you can do so safely, wade into stream, walking upstream. Take sample upstream of your body. For lakes, sample at dam or shore.
- Uncap bottle, fill it partly, cover with cap, shake to rinse inside bottle and cap, and empty behind you.
- Repeat twice (rinse 3 times)
- Then completely immerse bottle in water, let it fill completely, and cap under water.
- Put in cooler with ice or frozen ice pack.
- Fill out field data sheet with your name, date and time of sampling, and samples taken.
- Deliver to lab and sign bottom of field data sheet at that time.

Lake and Stream Sensitivity Explained
How aquatic environments respond to acid deposition depends on their sensitivity to acids and the quantity of acids received. Most environments are naturally buffered against acid input by neutralizing materials such as limestone. If sufficient buffering capacity exists in an environment, excessive acid input does not change the pH of the water, although it will progressively deplete its acid neutralizing capacity (ANC). The soils, bedrock, and vegetation of watersheds largely determine the capacity of aquatic resources to accommodate acid deposition, but other factors play an important role. Acid neutralizing capacity can have its full effect only when the incoming precipitation has sufficient contact time with the neutralizing material. Areas with steep slopes, shallow soils or frozen ground tend to minimize contact time, resulting in incomplete neutralization of water entering lakes and streams. Additional neutralization is provided by the biota. For example, algae generate buffering materials during photosynthesis, and microbes living in bottom sediments reduce sulfur compounds to inert forms.ANC and pH interact in an unusual way: as acid is added to a buffered system, pH changes little until the ANC approaches zero. Then, small additions of acid cause large changes in pH. Finally, pH drops precipitously and permanently to levels that few aquatic organisms can tolerate.
With lower pH, levels of toxic metals leached from the watershed increase, aquatic growth is reduced, and sensitive species ranging from fish to algae disappear. If this occurs in a drinking water supply, metals will dissolve from distribution pipes resulting in high levels of iron, copper, lead and other metals.
|Category||Acid Neutralizing Capacity (mg/l)|
|Acidified||≤0 and pH≤5.0|
|Critical||0 - 2 or <0 and pH≥5.0|
|Endangered||2 - 5|
|Highly Sensitive||5 - 10|
|Sensitive||10 - 20|
