1. For on-site measurements I use the photometer Lovibond MD200 5-in-1.

2. I  invented  healthy  water in  my  controlled...so  if  i  got  through  international  research  center my  knowledge value  exchanged  in currency  my  offer  i  say  and  i  help  to  supply  healthy  water  to  all  countries  problem  sloution

3. Formula  spread   mouth  wants  Dollars  Rupees 

4. In order to test and calculate is chem calc and/or color metric as offer before

   by others. a other calculation is how big is the alkaline buffer in that water to

   adjust the PH to your needs.

    

5. In order to calculate alkalinity, you need either: a) to know concentration of calcium carbonate, or b) titrate the water (about 50 mL) in question with a dilute sulfuric acid (~0.01 N) to pH 4.5 for total alkalinity, and use the following formula

   Alkalinity = [mL acid][Acid][Normality][ 50,000] 

6. Google EPA Method 310.1

   1. I concur with Joseph, EPA is a workable solution. Alkalinity by Tritation.

7. I always leaned in Lab Basic chemistry to tritrate using H2SO4. https://www.mt.com/us/en/home/perm-lp/product-organizations/ana/titration-solutions.html?cmp=sea_03010127&SE=GOOGLE&Campaign=MT_ANA-TI_EN_US&Adgroup=Titration+-+BMM&bookedkeyword=%2Btitration&matchtype=b&adtext=350407140187&placement=&network=g&kclid=_k_EAIaIQobChMI6t-Qx93N4gIVl-DICh1_IQbwEAAYASAAEgLPXvD_BwE_k_&gclid=EAIaIQobChMI6t-Qx93N4gIVl-DICh1_IQbwEAAYASAAEgLPXvD_BwE

8. If you search for Alkalinity of Anaerobic, you will see How to cal ALK and VFA, But ALK as CaCO3 has been used for this formula by using MW of its. For ALk such as M, P ALK in Boiler as well you can fine out easily. But if your are studying for ALK in term of Pure Chem Theory these will be a lots of details. Hopefully these will support your need.
