eHualed to t"e measured data above 1ong &un 'lus t"e measured data t"at is disc"arge from 1ong &un. T"e bar

called @1ong &un s"ould be t"e sum of all t"e additions. It is noticed t"roug"out t"is re'ort t"at t"e bars do not add

u' and t"ere is a degree of c"ange. &efer to t"is gra'" to "el' understand t"e stacked bar gra'"s wit"in t"is 'acket.

T"e following gra'"s are outlined in suc" a way t"at a timeline of com'arative inter'retation can

be witnessed. >=lease make note t"at t"ere are certain sites on certain dates t"at t"ere was no data

collected.?

. '- J e*'resses t"e amount of Acidity or Alkalinity wit"in t"e water measured. Above is"ig"er Alkalinity and below will be more acidic.

T"ese gra'"s give an idea t"at t"e 5ort" /ork

graduals decreases in '- as we move

downstream and acHuires more Acid !ine

:isc"arge. 1ong &un 'resent t"e most

influence u'on t"e stream. At t"e 'oint w"ere

1ong &un enters t"e stream t"e 5ort" /ork

"as a significant decreases in Alkalinity.

more 'reci'itation you "ave wit"in t"e

waters"ed t"e "ig"er t"e flow will be. T"e

"ig"er t"e tem'erature t"e "ig"er rate of

eva'oration and t"is goes along wit" t"e

current season. T"ese gra'"s "ave a certain

disconnect between t"at relations"i'. /or

instance t"e flow in ;une 2$ is roug"ly t"e

same as /ebruary 2$. Ket /ebruary 23

"as a lower flow t"an in /ebruary of 2$.

It can be seen "ere t"at 1ong &un is t"e maor contributor of Iron to t"e 5/7&. /ebruary 2$

s"ows t"e most Iron load from 1ong &un out of all of t"e dates. T"is can "ave a relations"i' wit"

t"e flow on t"is date. A 'ossibility is t"at a "ig"er flow can yield a "ig"er Iron load.

4. Aluminum 1oad8

T"ere is anot"er relations"i' wit" flow and

Aluminum as noticed wit" t"e Iron load. T"e

"ig"er t"e flow t"e "ig"er t"e Aluminum load.

Also it is seen t"at 1ong &un is a maor

contributor to 5/7&.

!anganese is 'resent during bot" mont"s and "ave an intolerable "ig" load. It is noticed t"at

!ine 2 and 1ong &un contribute muc" of t"e !anganese t"at is 'resent in t"e 5ort" /ork.

,. -ot Acidity( t"e conce't of t"e gra'"s is to 'oint out t"e alkalinity 'resent. T"erefore

negative tons of acidity >Alkalinity? could be used to neutraliLe @M tons of acidity.

-ot Acidity is eHualed to t"e lack of

Alkalinity in t"e water t"at is needed to

neutraliLe t"e intensity of t"e acid. T"is is

one of t"e most im'ortant conce'ts involved

wit" Acid !ine :rainage. As t"e disc"arges

"it t"e 5ort" /ork t"e acidity of t"e waterincreases. T"is is evident wit" every date

'ictured.

Table 8 T"is table re'resents t"e 1ime >CaC63? t"at is needed to neutraliLe t"e '- t"roug"out

t"e year based on arc"ival data.

Conclusion8

In conclusion it is believed t"at t"e data collected s"ows a decrease in '- an increase in metals

and an increase in t"e amount of alkalinity t"at needs to be added in order for t"e water to reac"

a 'oint of neutrality. T"e largest contributor to t"e 'roblem is 1ong &un w"ic" is t"e furt"est

'oint downstream t"at is monitored by /riends of 7lackwater. A!: t"at is disc"arged from

multi'le non(source 'oints is t"e most critical im'act to t"is waters"ed.
