soils and earth by storm flows, alteration of topography and/or drainage,
changes in flow patterns or mechanical disruptions (such as boat wakes). Signs
of erosion can include gullies, undercut banks, slumping, and higher turbidity
in adjacent waterways. Eutrophic Pond A pond receiving an
excess of nutrients, especially phosphorus, from the surrounding watershed will
experience a greatly accelerated rate of plant growth. Plant growth and
decomposition is a naturally process but when the nutrients cause excessive
growth the natural system is overwhelmed. The result is often thick plant and
algae growth in a pond, loss of biodiversity, stressful conditions for aquatic
life and the potential for complete collapse of the natural ecosystem. Eutrophication Eutrophication is
the natural process of nutrients entering a water body resulting in increased
biological activity. The natural processes may be accelerated and intensified
by human activities that cause excessive quantities of nutrients to flow into a
water body leading to unchecked growth of aquatic plants, subsequent depleted
oxygen levels and in some cases the collapse of the aquatic ecosystem and the
premature succession of the area a wetland or upland. Executive Order 418 Governor Swift

Program (local sanctuary is Stellwagen Bank) Non-native plants Plants from
another region or continent introduced to an area. Non-native plants usually do
not have the same checks and balances in place, as is the case with native
species, and the result is often rampant invasion and excessive growth by the
non-natives (hence the term invasive species). Areas domi NPDES National Pollutant Discharge

prone to causing problems in ecosystem function or to the health, enjoyment, or
aesthetic value of an ecosystem. Nutrients, (nitrates and phosphates) Nutrients
are essential for growth in both plants and animals with nitrogen and
phosphorus being significant for growth in plants. There are several common
forms of nitrogen including nitrite, nitrate, and ammonia. Nitrate is a form of
nitrogen easily absorbed and used by plants and is a byproduct of the oxidation
of ammonia. Phosphate usually occurs in low concentrations in water and plant
growth in fresh water is limited by the amount of phosphate present in the
water. On-site Systems An individual

spawning areas, decrease in light penetration, increase in scour and an
increase in bacterial and other pollutants.
Septic systems/ on-site systems These
are decentralized waste treatment systems usually installed for an individual
or cluster of houses. A septic system replaced the historic practice of direct
discharges of wastes to water bodies and provides an adequate level of
treatment and contributes to groundwater recharge when designed, installed and
maintained properly on suitable soils. SRWC Saugus River Watershed

wastewater or nonpoint source pollution problems in the community. Storm water Phase 2 Requirements Storm
water controls are found in a section of the federal Clean Water Act regulating
pollutant discharges to waterways
(NPDES). Phase 2 is an effort to reduce the pollution sources entering
waters via storm water runoff from medium sized municipal areas. Areas meeting
the size or density requirements will have to develop and implement a storm
water management plan encompassing six minimum control measures under a general
permit issued under the auspices of the Clean Water Act. Stream Team A group of volunteers
focusing effort and energy on a specific stream or reach of a river. Stream
teams may undertake one or more of a variety of initiatives such as shoreline
visual surveys, river cleanups or educational outreach. Subdivision standards The
ordinances and requirements enacted by a community to govern proposed
subdivisions. Standards could involve density of development, road and sidewalk
design, water use, turf management, and more. Surface and ground water Surface
water is all water at or above the grounds surface. Often the most concerned
lies with fresh water because of the worlds heavy reliance on surface water
for drinking and other uses. Ground water is the fresh water found beneath the
surface of the planet in the spaces between soil particles, bedrock
faults/cracks, etc. Ground water, particularly the water found in aquifers, is
also an important source of drinking water. SWIM -- Safer Waters in TIE/TRE Toxicity Identification
and Toxic Reduction Evaluation. Title 5 The Total Maximum Daily Load (TMDL) A
section in the Federal Clean Water Act
requiring each state to identify water bodies that are not meeting their
assigned water quality standard, ascertain the causes of impairment and
determine the maximum amount of that pollutants a waterway can receive, yet still meet water quality standards. Using
this amount, a TMDL establishes the allowable pollutant loading from all
contributing sources so the total, including a margin of safety, falls at or
below the maximum daily allowable pollutant load. Total Phosphorus Phosphorus is a
nutrient essential for the growth of most plants. Phosphorus can be found in
both the organic and inorganic forms. Total phosphorus is a measure of both
these forms. Tributary A stream or river
flowing into a larger, mainstream river. Underground Storage Tanks (USTs) These
are storage tanks buried beneath the surface of the ground. These tanks
frequently contain gasoline (such as those at service stations or airports),
home heating oil or other petroleum products. USTs are relatively inaccessible
and are difficult to monitor for leaks, (LUSTs or leaking underground storage
tanks) posing a threat to groundwater and surface waters. Wastewater Water that is used for
some purpose then discharged or wasted.
Usually refers to the water used in households, business and industry. Water Management Act (MGL Chapter
21 G) The intent of the WMA is to manage water uses, maintain safe yields, and
plan for future water needs and this is done through the issuance of permits to
withdraw set volumes of water fro Watershed An area of land
contributing runoff/drainage to a common point.
Large watershed may be divided into smaller sub-watersheds. Wetland resource area An area of
land with saturated or nearly saturated soils most of the year serving as an
interface between land-based and water-based environments. Wetlands provide
many benefits including pollution attenuation, groundwater recharge, valuable
plant and animal habitat. Wetlands are protected under the Massachusetts
Wetland Protection Act as resource areas. Glossary Prepared by the Riverways
