2 INTRODUCTION
The Massachusetts Division of Water Pollution Control, in cooperation with the Metropolitan Area Planning Council (MAPC), undertook during 1977 an extensive water quality monitoring program in the major river basins of the MAPC 208 management area. This program was multi-faceted with water quality sampling of surface waters, sampling of stream sediments, and sampling of benthic invertebrates. In addition, a special survey was conducted in Marblehead Harbor to assess the impact of vessel discharges and to determine the overall water quality of this popular and extensively used harbor.
This report presents the results of the analyses performed on the hundreds of samples collected during the duration of this project. Chemical analyses were performed at the Lawrence Experiment Station of the Department of Environmental Quality Engineering, according to procedures described in the American Public Health Association's document Standard Methods for the Examination of Water and Wastewater (14th Edition, 1976, New York). The benthic invertebrate samples were analyzed by biological staff personnel of the Division's Water Quality Section, according to methods recommended by the United States Environ mental Protection Agency. The data was recorded and placed in tabular form by personnel of Division's Water Quality Section.

At each station surface observations were made and the aquatic macrophyton, stream width and depth, and substrate types were recorded, Each substrate tYPe was sampled for its resident benthic macroinvertebrate community by employing the most appropriate piece of sampling gear.
This survey was~ designed for quantification buewas rather a qualita tive, or habitat, reconnaissance. For each station, a brief description of the sampling site and a list of invertebrates collected is given. A brief analysis of organisms response to existing water quality is also given.
It should be kept in mind that this survey was not conducted on an intensive basis and, therefore, the results should not be---;;;ed for anything other than a baseline approach.

FIGURE M 179 Each organism collected was assigned one of the three following organic pollution tolerance classifications based on a survey of the literature and upon field observations,
Tolerant (T) - organisms frequently associated with gross organic contamin ation and generally capable of thriving under partially anaerobic conditions.
Facultative (F) - organisms having a wide range of tolerance and frequently associated with moderate levels of organic contamination.
Intolerant (I) - organisms that are not found associated with even moderate levels of organic contaminates and generally intolerant of even mod erate reductions in dissolved oxygen.
*NOTE: At the request of MAPC, wherever possible sampling stations were located in impoundments. However, a few riffles were sampled, The differences between these two habitats are many; physical, chemical, and biological, Specific compari sons of benthic conmunities of the two habitats are very difficult. For this reason the physical description for each station should be kept in mind when the kinds and per centages of organisms are reported.
180 Station ASO2 was located on a stretch of the Assabet River approximately 15 feet wide with a maximwn depth of 6 inches. The substrate was mostly rubble, gravel, and sand the entire width. The stream flow was good with no visible signs of stress.
The dominate macrophytes were pickerelweed and sedge. These were restricted to the west bank as the east bank was completely shaded.
A total of 19 kinds of organisms were collected: 43% intolerant, 31% facultative, and 26% tolerant. Black flies and caddisflies, both in• tolerant kinds, were the dominant organisms. The station as a whole exhibited good diversity with the percentage of intolerant kinds indi cating a healthy benthic conununity and good water quality.

182 Not quite three miles downstream Station AS06 exhibited a marked change in appearance. The river became murky and emitted a septic odor. The width ranged from 10 to 35 feet and the depth fran 6 inches to 3 feet.
The macrophytes observed were pickerelweed and Salix sp., a member of the willow family.
Almost s reversal in the percentage distribution £ran AS02 occurred at this station. Only 12 kinds of organisms were collected here with 50% being tolerant types. Oligochaetes were by far the dominant organisms although intolerant black fly larvae were present. (Black fly larvae - Simuliidae have been classified as intolerant but field observations indicate that they inhabit a wide variety of conditions.)
Other than midges and black flies no aquatic insects were found. Only isopods, leeches, and shellfish were present in addition to the worms. This drastic change would indicste a possible source of organic pollution somewhere between AS02 and AS06.

183 Station AS14 was located at Cox Street in Hudson. The river was approxi mately 50 feet wide with the west bank flooded over another 40-50 feet, The depth was a uniform 2-3 feet. Sand and muck comprised most of the substrate with some gravel and detritus. Other than the water being slightly colored, no visible signs of gross pollution were evident.
The mscrophytes were more diverse than at stations AS02 and AS06. Pickerel weed and cattails were the dominate emergents and submerged vegetation in• eluded coontail, grasses, and Salix sp,
A total of 38 kinds of organisms were collected here with many intolerant mayflies, damselflies, and midges present which were absent at the above stream stations. Although the percentage of intolerant kinds did not change from AS06 (25%), the number of intolerant kinds more than tripled (10).
The percentages - 25% intolerant, 46% facultative, and 29% tolerant - along with the increase in the total number of kinds (38) indicates a shift toward recovery from the stressed condition at the previous station,

185 Station AS15 was located above the dam at Route 62 in Gleasondale. River width was 40 feet and maximum depth was 8 feet at mid-channel. The sub strate consisted of muck and detritus along both shorelines but the center channel had been scoured. No signs of gross pollution were observed but the water still retained some color,
Cattails, grasses, and sedge remained the dominant macrophytes. Duckweed lined both shorelines and has been noted as a problem in the past.
The percentages recorded here - 23% tolerant, 60 % facultative, and 17% intolerant - were very similar to the previous station (AS14) with a definite dominance of facultative kinds. The organisms collected showed little change in the response to the water quality, The intolerant may flies, midges, and black flies found here were the same kinds as at AS14.

187 Above the dam at the intersection of Routes 62 and 117 in Maynard was the location of Station AS17. The river was approximately 150 feet wide but widened to a maximum of 300 feet about 50 feet above the dam before narrowing back to 150 feet again, Maximumdepth was 5 feet, Both banks consisted of muck and the center channel of sand and gravel, Surface observations revealed more water color than at Stations AS14 and AS15, Oil was observed on the surface and in the sediment. The macrophytes along the shoreline consisted of pickerelweed and sedge with milfoil the daninant submerged vegetation.
A total of 16 kinds of organisms were collected here, Of the 16 only one intolerant mayfly (Siphlonurus sp.) was found. There were, however, other mayflies and midges present but all of facultative tolerance.
Again, facultative organisms were daninate, accounting for 75% of the total. This increase of facultative types and the near absence of intolerant types indicated a slight drop in response to the water quality which would be expected in an impoundment of this type.

189 Station AS19 was located at Route 62 on the Acton/West Concord line. The river was approximately 30 feet wide and the depth varied from one to two feet. The substrate consisted of sand, gravel, and rock with some muck on the shorelines. Riffle areas and overall good flm,1 characterized this station. No visible signs of gross pollution were evident.
Pickerelweed was the dominant emergent macnophyte on both shorelines. Sub merged vegetation included Elodea sp. and Crispus sp. along with some filamentous green algae.
A positive benthic response to the water quality here was indicated by the abundance of intolerant mayflies, midges, and black flies. While the tol erant and facultative kinds remained the same or declined in nU111bersand percentages, the intolerant kinds rose considerably from 6% to 30% of the total number collected. In the three river miles downstream from the previous station, the benthic conmunity showed a marked recovery frmm the stressed condition at AS17.

191 Station AS22 was located at the end of Assabet Avenue in West Concord. The river was 40 feet wide with a nearly uniform depth of four feet, The substrate consisted of sand and gravel the entire width. A moderate to good flow with no visible signs of gross pollution was obseived though the water was dark.
Other than low growing shrubs and grasses on the shorelines, no aquatic macrophytes were observed.
Again intolerant mayflies, midges, and blackflies were present and the n1.1111berof tolerant kinds was low (two). The only noticeable change was a rise in the n1.1111berof facultative kinds. Though the physical charac teristics of this and the previous station were very different (riffle areas opposed to channeled), a comparison of the two benthic communities would indicate very little change in the water quality.

193 Station NEOl was located at a riffle area just below the Neponset Reservoir Dam. This small riffle, 15' long and 10' wide, fed a channel which wound its way through a large marsh. Sand and gravel comprised the substrate of the riffle. There was good flow through the riffle and the water level was high in the surrounding marsh. No signs of gross pollution were evident.
Cattail was definately the dominate emergent macrophyte with some pickerel weed along the shorelines. Submerged vegetation included coontail and milfoil. Duckweed and yellow water lilies were observed as the floating types present. All the vegetation present in the marsh area was at least moderate; most abundant.
The heavy population and good diversity at this station pointed to a healthy benthic cOlllllunity. Though facultative (52%) and tolerant (l'.J%) organisms together accounted for 82% of the kinds found, intolerant midges, elmid beetles (Stenelmis sp.), one csddisfly (Hydropsyche betteni), and one amnicolid snail found indicated that the water was able to support sensi tive organisms. However, no "clean water" mayflies or stoneflies were found. Generally, Station NEOl exhibited a good response to the water quality.

195 Above the dam at Crackrock Pond was the location of Station NE02, This small pond was approximately 50 feet wide with a depth of four feet, The substrate was muck, from shoreline to shoreline, and was heavy with oil, Only moderate flow was noted.
A heavy growth of grasses lined the shorelines, with some pickerelweed and wild iria mixed in. The submerged vegetation was very abundant with coontail and filamentous green algae. Duckweed covered much of the peri meter of the pond.
A negative benthic response to the water quality occurred at Station NE02. Tolerant organisms became the dominant kinds accounting for 52% of the number of kinds found. Beetles, leeches, snails, and worms were the represen tative tolerant kinds. Only a few intolerant midges and amnicolid snails were found.
The lack of "clean water" ocganisms, the dominance of the tolerants, and the presence of oil in the sediment and on the shoreline indicated a con dition of stress. The benthic c0111Dunitydefinately showed an adverse response to the water quality at this station.

197 Station NE04 was located above the dam at South Street in Walpole. The river was 30 feet wide and three feet deep. Muck and detritus comprised the substrate and banks. The flow was moderate and the water appeared dark.
Both banks were shaded but sunny spots were abundant with pickerelweed. Floating water lilies and duckweed were also observed.
A good recovery from the stressed conditions at NE02 was noted at this station. A marked increase in both the facultative and intolerant kinds coupled with a sharp drop in the tolerant kinds indicated a much better response to the water quality.
The diversity at this station was also encouraging. The whole range of macroinvertebrates was covered; from stoneflies and mayflies to snails and oligochaetes. The midge population characterized this diversity with eigh teen different genera collected. The tolerance distribution of the midges was not too different from the benthic couununity as a whole. overall, the benthic community exhibited a diverse, healthy response to the water quality.

199 Above the dam on West Street in Walpole was the site of Station NE05. The river was approximately 35 to 40 feet wide and three feet deep. The sub strate consisted of muck and detritus which was heavy with oil and a strong hydrogen sulfide (H2S) smell. Oil was observed floating on the surface as well. (A large parking lot was situated on the west bank.) The flow was slow to moderate.
Pickerelweed was moderate along the east bank. A few water lilies were observed amidst an abundance of filamentous green algae.
A sparce benthic population was recorded at this station. Only 16 kinds were collected here as opposed to 33, 36, and 45 at the previous three stations respectively. Of the 16 kinds collected, oaly one intolerant midge was found. A drop in the percentage of intolerant organisms (6%) and a rise in both the facultative (69%) and tolerant (25%) kinds further indicated a decline in the benthic response to the water quality.

201 Station NE07 was located above the Bird Pond Dam in Walpole. The pond was approximately 300 feet wide with a depth of three to eight feet. The sub strate was mostly muck with sand along the shorelines, Again the water appeared dark and oil was observed on the surface, The flow was slow to moderate,
Pickerelweed and Wild Iris growing on the shorelines were the only macro phytes observed.
As at NE05, only 16 kinds of organisms were collected here. However, the percentage distribution improved slightly. Intolerant kinds accounted for 25% of the total with both the facultative (56%) and tolerant (19%) kinds declining. The relatively low number of kinds and the more favorable percentages indicated a slight improvement in the benthic response to the water quality.

203 Station NE08 was located off Canton Street near Route 128 on the Norwood, Dedham, Canton line, The river was 30 feet wide with a depth of four feet. The substrate was primarily detritus with some sand. Again the substrate contained a large amount of oil and the flow was slow to moderate.
Only a few sedges were observed along the shorelines.
What little benthic improvement was noted at NE07, disappeared at NE08. Percentages of both intolerant (15%) and facultative (39o/J kinds declined while the tolerant kinds rose to 40% of the total. The total ntanber of kinds collected dropped to 15, the lowest of any of the stations. overall, this station exhibited a poor response to the water quality.

205 Station Ip03 was located on Martin's Brook at Park Street in North Reading. The brook was 10 feet wide and approximately two feet deep. The substrate consisted of sand, gravel, and rock. The water exhibited a very dark color. The flow was moderate to fast. Pickerelweed was the dominant emergent macrophyte. The submerged vegetation included coontail and mosses.
A very diverse benthic c00Dllunity was found at this station. The snail population reflected this condition as representatives of all three tol erance groups were collected. Intolerant mayflies, stoneflies, midges, caddisflies, and black flies were also collected. In addition, the per centages of kinds collected (25% Tolerant, 40% Facultative, and 35% In tolerant) furoher indicated a healthy comnunity and a very good response to the water quality.

207 Station Ip05 was located just above the dam at the B,B. Chemical Company in Middleton. The river was approximately 30 feet wide with a maximlllll depth of five feet. The substrate was sand, gravel, and rock, Other than the same dark color of the water, no visible signs of pollution were observed, The flow was good.
Again pickerelweed was the dominate emergent and milfoil, starwort, and grasses comprised most of the submerged vegetation.
Much less diversity and a lack of clean water mayflies, stoneflies, and black flies indicated a condition of stress at this station. Snails, leeches (which feed on snails), odonates, and amphipods were the dominate organ:sms; all tolerant or facultative kinds. The only intolerants found were one genus of snails and three genera of midges living in the vegeta tion,

209 Station Ipl3 was located abOV!ethe Willowdale Dam in Topsfield. The river was approximately 50 feet wide with a msximum depth of five feet, The substrste was mostly sand and gravel covered with vegetation, Again there was good flow and the water appeared very dark,
Thick vegetation lined both shorelines and submerged vegetation extended across the entire width of the river. Pickerelweed was again the dominant emergent. Submerged vegetation included pondweed, Elodea sp., milfoil, and filamentous green algae. Floating watershield, water lilies, and duckweed were abundant also,
Only six kinds of organisms were collected st this station, which is too few to draw any valid conclusions.
The thick vegetation in the river made it very difficult to get a good dredge sample, The few organisms collected were picked from the vegetation not the sediment, Many tolerant adult water striders (Gerris sp,) and whirligig beetles (Gyrinidae sp.) along with facultative adult damselflies (Aeshnidae sp,) were observed on the surface, Generally, the water quality appeared unchanged from the previous station and the lack of benthic or ganisms found cannot be readily explained.

210 Station Ipl4 was located above Sylvania Dam in Ipswich. The river was 40 feet wide with a maximum depth of seven feet. The substrate consisted of muck and sand. The water was still very dark with good flow.
Pickerelweed was still the dominant emergent macrophyte with some water willow along both shorelines. The submerged vegetation consisted of pond weed, Elodea sp., and filamentous green algae.
The benthic community at this station was vecy similar to that at station Ip03. A repopulation of intolerant mayflies, damselflies, and black flies was observed which had been absent at the two previous stations {Ip05 & Ipl3). This would indicate a slight improvement in the response.to the water quality.
Overall, the benthic response was good at station Ip03 but quickly showed a downward shift at stations 1p05 and 1pl3. Station 1pl4 revealed a slight benthic recovery, possibly indicating a better response to the water quality than at 1p05 or Ip13.

The term 'water pollution' has acquired many connotations. Literally, the word 'pollute' means 'render impure'; thus, in this sense, any water con taining matter other than its chemical constituents of two parts hydrogen to one part oxygen would be considered polluted. Such 'pure' water, however, is never found in natural bodies; the ecological balance in a waterbody is dependent upon the presence of other material. In this report, water pollution refers to a condition which is in contravention of the Water Quality Standards. Pollution degrades the physical, chemical and bacterial quality of a waterbody and can make it unsightly, malodorous, and a health hazard. Pollu tion occurs mainly through the discharge of wastes from homes and industries. The various types of pol ution are: 1) oxygen-demanding, such as originates from domestic sewage and certain industrial wastes; 2) toxic materials as in some industrial wastes; 3) radioactive wastes; 4) thermal; 5) bacterial; 6) oil; and 7) physical. Stormwater runoff from both urban and rural areas can also add pollutants to a waterbody.
The extent of pollution in a particular waterbody is determined by measuring certain chemical and biological constituents and properties. Chemical con stituents, such as dissolved oxygen, phosphates and metals, are generally measured in milligrams per liter (mg/1); since the unit weight of water,is 1.0 grams per milliliter, milligrams per liter are roughly equivalent to parts per million for a solution which is mostly water.
Dissolved Oxygen (D.O.) refers to the uncombined oxygen in water which is available to aquatic life. Since this oxygen is consumed more rapidly in the decomposition of wastes, the D.O. gives an instantaneous picture of the condition of a waterbody. Time of day and temperature of the water are important in interpreting D.O, levels. Temperature affects the amount of oxygen which water can contain. Time of day is related to the effeats of algae. Algae consume oxygen through respiration throughout the day and night. During daylight hours, they add oxygen through photosynthesis. D.O. levels are therefore generally highest during the afternoon and lowest just before sunrise.
Biochemical Oxygen Demand (BOD) measures the amount of oxygen required by bacteria to decompose organic matter. The BOD is gradually exerted in two stages. In the first stage, carbonaceous matter is stabilized, while nit rogenous substances are broken down in the second stage. The second stage (nitrification) usually begins after seven days. The ultimate, or total BOD from both stages may require an incubation period of 30 days or more. Through recurrent use, the 5-day BOD has become the standard test used in water quality analysis,
Chemical Oxygen Demand {COD) refers to the amount of oxygen required to chemically oxidize waste material. Since some of the organic matter in a waste cannot be decomposed by microorgRnisms but can be broken down by chemical oxidation, the COD is generally greater than the BOD. The COD is especially useful in analyzing a waste that contains a great deal of non-biodegradable matter.
220 Total Solids measures all solids in water including suspended snd dissolved, organic and inorganic. They are measured by evaporating. the water from a sample of known volume and measuring the residue remaining. The residue can then be ignited in a laboratory furnace to determine the organic portion The loss on ignition is considered organic and the remaining residue, known as fixed solids, is considered to be inorganic.
Suspended Solids are those which can be removed by passing the water through a filter. The remaining solids are called dissolved solids. Suspended solids provide a good measure of the efficiency of a sewage treatment plant: primary treatment should remove about 50 percent of the suspended solids, while secondary treatment should remove about 90 percent.
Coliform Bacteria are found in abundance in the intestinal tract of warm blooded animals. They are not harmful in themselves, but their presence indicate& that pathogenic bacteria may also be present. Since they can be detected by relatively simple test procedures, coliforms are used to indi cate the extent of bacterial pollution from sewage. Bacterial tests usually measure the fecal and total coliforms. Fecal coliforms make up about 90 percent of the coliforms discharged in fecal matter. Non-fecal coliforms may originate in soil, grain, or decaying vegetation.
£!! measures the hydrogen ion concentration on an inverse logarithmic scale ranging from Oto 14, pH values under 7 indicate more hydrogen ions and, therefore, more acidic solutions; pH values over 7 indicate fewer hydrogen ions and, therefore, more alkaline solutions. A pH of 7.0 indicates a neutral solution, Alkalinity is a quantitative measure of the alkaline materials present, while acidity is a quantitative measure of acidic materials.
Nutrients are compounds which act as fertilizers for aquatic organisms. Small amounts are necessary to the ecological balance of a waterbody, but · excessive amounts can upset the balance by causing excessive growths of algae· and other aquatic plants. Sewage discharged to a waterbody usually contains large amounts of carbon, nitrogen, and phosphorus. The concentra- . tion of carbonaceous matter is reflected in the BOD test. Additional tests are run to determine the concentrations of nitrogen and phosphorus.
Phosphorus appears in waterbodies in canbined forms known as ortho- and poly phosphates and organic phosphorus. The majority of the phosphorus contained in domestic sewage and industrial wastes comes from detergents. Additional phosphorus may enter a waterbody in agricultural runoff where fertilizers are used,
Nitrogen in the form of organic nitrogen normally decomposes into ammonia nitrogen, nitrite-nitrogen, and nitrate-nitrogen. Since each decomposition reaction is dependent on the preceding one, the progress of decomposition can be determined in terms of the relative amounts of these four forms of nitrogen,
221 Ammonia-Nitrogen (NH3-N) is present in sewage and is also.generated from the decomposition of organic nitrogen. In can also be formed when nitrites and nitrates are reduced. Ammonia is particularly important since it has high oxygen and chemical demands and is also toxic to fish.
Nitrite-Nitrogen (No2-N) is the oxidation product of ammonia. It has a fairly low oxygen demand and is rapidly converted to nitrate. The presence of nitrite nitrogen usually indicates that active decomposition is taking place.
Nitrate-Nitrogen {N03-N) is important since it is the end product in the aerobic decomposition of nitrogenous matter. Nitrogen in this form is readily available to plants.
Total Kjeldahl Nitrogen (TKN) includes ammonia and organic nitrogen but does not include nitrite and nitrate qitrogen. Thus it is a measure of the po tential for oxygen consumption of the nitrogenous matter in the water.
Turbidity is the measure of the clarity of a water sample. It is expressed in Nephelometric Turbidity Units (NTU) which are related to the scattering and absorption of light by the water sample.
Color is determined by visual comparison of a sample with known concentrations of colored solution and is expressed in standard units of color. Certain waste discharges may turn water to colors which cannot be defined by this method; in such cases, the color is expressed qualitatively rather than numerically.
Chloride (Cl-) is one of the major anions in water and sewage. A high chloride content can exert a deleterious effect on pipes and structues, as well as on plant life. The use of road salts is a major source of excessive chlorides in surface and groundwaters.
Specific Conductance yields a measure of a water sample's capacity to convey an electric current. It is dependent upon temperature and the concentration of ionized substances in the water. Distilled water exhibits specific con ductance of 0.5 to 2.0 micromhos per centimeter (µmhos/cm), while natural waters show values from 50 to 500 µmhos/cm.
The above parameters are measured in most water quality surveys. Other con stituents such as metals or oil and grease are measured in areas where parti cular problems are known to exist. Microscopic examinations are conducted on mott surveys to determine the number of algae and other microorganisms present. Additional samples of the river bottom sre usually collected in order to deter mine the types of deposits present. Decomposition of orgsnic suspended matter which settles to the bottom will exert an oxygen demand on the water.
222 Two types of samples are collected for analysis: grab and composite. A grab sample is an instantaneous sample collected to show conditions at a particular time. Composite samples are collected over a period of time at specific in tervals, giving a better picture of the overall water quality situation for the time covered.
Certain levels of the shove parameters occur naturally in waterbodies. Since these levels vary among the different ponds, streams, and coastal waters, the following tables are presented for the sake of reference. Table sum marizes the numerical limits for certain parameters as specified by the Massachusetts Water Quality Standards. Table lists levels found in unpol luted reaches of various Massachusetts waters.

* These water quality standards are currently undergoing revision. The new revised standards will be published in 1978,
** No bacterial limit has been placed on this class because of urban runoff and combined sewer problems which have not yet been solved. In waters of this class not subject to this problem the criterion shall be less than an average of 5,000 coliform/100 ml. during any monthly sampling period. TABLEV-B
